Your uncle wants to create a dog small enough to fit into a purse. Of the hundreds of dogs on his farm, he breeds only the smallest 10% of them. He then breeds only the smallest 10% of their offspring, and continues to breed only the smallest 10% of each generation. Over 20 years, his group of dogs did become smaller (though not small enough to fit into a purse). Did he witness evolution?
Answer:
Yes, he witnessed a little bit of evolution.
Explanation:
Evolution is based upon the change in the heritable characteristic features of a species over time. This change does not happen suddenly, it happens gradually over generation after generations. The change in characteristic expression of genes are passed through from parents to their offspring during reproduction.
He kept on breeding only the smallest one's generation after generation for long 20 years. His end result was having the smallest puppies though they are not too small to fit in the purse but still, evolution happened.
The process of selecting animals with desirable traits across successive generations represents a type of evolution through artificial selection.
The genotype of an organism is the combination of alleles observed in that organism. Moreover, a phenotype is the sum of all observable characteristics of the organism.
In artificial selection, animals or plants with desirable phenotypic traits are selected by humans to reproduce.
The process of artificial selection changes allele frequencies across generations, thereby leading to the evolution of desirable traits in offspring since the phenotype is influenced by the genotype.
In conclusion, the process of selecting animals with desirable traits across successive generations represents a type of evolution through artificial selection.

Hydrochloric acid from the stomach is neutralized in the small intestine by
The pancreas secretes bicarbonate, which neutralizes the hydrochloric acid from the stomach in the small intestine, providing an alkaline environment necessary for intestinal enzymes to function.
Hydrochloric acid (HCl) from the stomach, which creates a highly acidic environment necessary for the enzyme pepsin to break down proteins, must be neutralized when the stomach contents move into the small intestine. This is because the enzymes in the small intestine, such as trypsin and chymotrypsin, require a more alkaline environment to function effectively. Therefore, an organ called the pancreas secretes a base named bicarbonate (HCO3-) into the small intestine, which neutralizes the hydrochloric acid, maintaining a suitable pH for digestive enzymes to operate.

Final answer:
Lions and tigers are more closely related to each other than to bears, as they both evolved from a common ancestor.
Explanation:
Scientists classify organisms not only by their physical features, but also by how closely related they are. Lions and tigers look like each other more than they look like bears, but are lions and tigers related? Evolutionarily speaking, yes. Evolution is the change in a species over time. Lions and tigers both evolved from a common ancestor. So it turns out that the two cats are actually more closely related to each other than to bears. How an organism looks and how it is related to other organisms determines how it is classified.

TASK: Describe and explain the many stages involved in the development of a human embryo and fetus, as well as the
need for proper pregnancy care, nutrition, and overall healthy choices during pregnancy.
The very first stage of the development is the fertilization of an egg .It takes about 24 hours for a sperm cell to fertilize an egg. When the sperm punctures the egg, the surface of the egg changes so that no other sperm can enter. At the moment of fertilization, the baby's genetic makeup is complete. The second stage is the two cells; this stage occurs approximately 30 hours after fertilization and results in a 2-cell embryo. The next stage is the 4 cell embryo is the result of a second cleavage event and occurs at approximately 40 hours after fertilization. The individual cells are called blastomeres. At this stage the process of embryonic genome activation is started in human embryos. Next is the 8 cell stage actually consisting of 6-12 cells develops by day 3 of human embryonic development now there is now an morula or early-stage embryo consisting of 16 cells (called blastomeres) in a solid ball contained within the zona pellucida . 5 to 6 days there is a blastocyst or embryo that will develop into a baby .The fourth week ball of cells is splitting into the embryo and placenta .The neural tube the building block of the spine brain and backbone is already formed.The amniotic sac and fluid are forming. This would be a good time for the mother to get good exercise as well as to stop drinking and smoking .The mother should also see a doctor and start taking prenatals. This is important because it helps with the development and growth of the baby . The next stage is 10 weeks. The baby is as big as a strawberry. At stage 16 the baby is the size of an avocado. 16 weeks of pregnancy the mother may notice an increase in energy .Sleep is important because lack of sleep can result in growth problems in the unborn baby. 20 weeks the baby is nearly formed this is the second trimester the mother should avoid raw meat,eggs,and fish. By 24 weeks your baby's organs are fully developed .

Which property would best distinguish sediment deposited by a river from sediment deposited by a glacier?
A) thickness of sediment layers
B) age of fossils found in the sediment
C) amount of sediment sorting
D) mineral composition of the sediment
Answer:
Which property would best distinguish sediment deposited by a river from sediment deposited by a glacier?
thickness of sediment layers
Explanation:
Glaciers deposit rocks unlike river sediment that are less thicker than glacier's own
The amount of sediment sorting is the best property to distinguish river-deposited sediment, which is well-sorted and stratified, from glacier-deposited sediment, which is unsorted and known as till.
Explanation:The best property to distinguish sediment deposited by a river from sediment deposited by a glacier is the amount of sediment sorting. Sediment deposited by running water, such as rivers, will exhibit a good degree of sorting because water's flow differentiates sediment particles by size, depositing them accordingly. This leads to stratified drift, with grains size and sorting differential layers indicative of water deposition. In contrast, sediment deposited by glaciers, known as till, is typically unsorted and consists of a chaotic mix of material of various sizes, reflecting the indiscriminate carrying and depositing power of glacial ice.
What do the elliptical orbits of the planets look like?
The elliptical orbits of the planets are oval-shaped paths determined by Kepler's laws, with the sun at one focus. Planets move faster when nearer to the sun and slower when farther, and some orbits appear nearly circular while others, like Pluto's, are more noticeably elongated.
According to Kepler's elliptical orbit law, each planet's path around the sun is an ellipse, with the sun situated at one of the focal points of this ellipse. This means the orbits are not perfect circles, but rather oval-shaped, with varying degrees of elongation.
While the orbits of the planets are indeed elliptical, many of them appear nearly circular due to their low eccentricity, which is a measure of the deviation of the orbit from a perfect circle. For example, the Earth's orbit is only slightly elliptical, appearing almost circular in many illustrations. However, some planets, like Pluto, have more elongated orbits. Moreover, as per Kepler's equal-area law, a line that connects a planet to the sun sweeps out equal areas during equal intervals of time, indicating that a planet travels more quickly when it is closer to the sun and more slowly when it is farther away.

Answer:
Origin of whales
Natural selection
Modern understanding
Explanation:
Origin of whales - In the first edition of "On the Origin of Species" in 1859, Charles Darwin speculated about how natural selection could cause a land mammal to turn into a whale.
Natural selection - To understand the origin of whales, it's necessary to have a basic understanding of how natural selection works. Natural selection can change a species in small ways, causing a population to change color or size over the course of several generations. This is called "micro-evolution."
Modern understanding - Darwin didn't know anything about genetics, Pobiner said. "He observed the pattern of evolution, but he didn't really know about the mechanism." That came later, with the discovery of how genes encode different biological or behavioral traits, and how genes are passed down from parents to offspring.

0% chance of producing an affected male offspring. Evaluate the validity of the hypothesis.
The researchers hypothesize that crossing any unaffected female and an affected male will result in a 0% chance of producing an affected male offspring - The hypothesis is correct
In the case of X-linked traits we know the following facts:
male being an XY is hemizygous for the X chromosome and it gets its X chromosome from female.Male get only Y chromosome from the male parentX chromosome only passed to female offspringSo in this case, X-linked trait is considered, if a male will get its chromosome from an unaffected female then there will be no chance of the male to be affected.Thus, The researchers hypothesize that crossing any unaffected female and an affected male will result in a 0% chance of producing an affected male offspring - The hypothesis is correct

https://brainly.com/question/945983
The hypothesis is valid as X-linked recessive traits would not affect male offspring from an unaffected female and an affected male, with males inheriting the Y chromosome from the father and a normal X from the mother.
The hypothesis that crossing any unaffected female with an affected male will result in a 0% chance of producing an affected male offspring needs to be evaluated considering X-linked recessive inheritance.
If the mutation is on the X chromosome and is recessive, an affected male (XY) has a mutant allele on his X chromosome.An unaffected female (XX) may be a carrier if she has one normal and one mutant allele.When they cross, the male will pass his Y chromosome to all his sons and his mutant X chromosome to all his daughters.Since the sons receive their X chromosome from the mother, who is unaffected, they will have a normal allele and not exhibit the condition.The daughters, however, will be carriers since they inherit the affected X from the father and a normal X from the mother.An accident victim receives a blood transfusion. Shortly thereafter, he begins to have difficulty breathing, develops a fever, and experiences nausea and vomiting. Which of the following is the most likely interpretation of these events?
a. the blood transfusion contained pyrogens.b. the blood transfusion was mismatched, and the recipient had previously been exposed to the blood group antigens of the blood transfusion.c. the blood transfusion was mismatched and contained pyrogens.d. the blood transfusion was mismatched.e. the recipient had previously been exposed to the blood group antigens of the blood transfusion.
Answer:
b. the blood transfusion was mismatched, and the recipient had previously been exposed to the blood group antigens of the blood transfusion.
Explanation:
Blood transfusion giving a patient blood or its equivalent product intravenously. Necessary tests are normally carried out to ensure the blood to be transfused matches and is compatible with the blood or body system of the recipient.
However when symptoms like difficulty in breathing, fever,nausea and vomiting is visible after ten transfusion then it’s obvious there was an error which involves blood transfusion being mismatched, and the recipient being previously been exposed to the blood group antigens of the blood transfusion
Answer:
b. the blood transfusion was mismatched, and the recipient had previously been exposed to the blood group antigens of the blood transfusion.
Explanation:
This incompatibility of blood groups, which leads to immune response of the recipient to recognise the donor's blood cells as antigens, and therefore attack the donor blood cells donated , causing lysis of the blood cells, leading to low oxygen saturation in the blood and difficulty in breathing and other complication.

Small frogs living in a marshy region feed on small insects in the region. The relationship between the frogs and insects is a relationship. A particular species of lizards is introduced into the marshy land. These lizards also start feeding on these insects. The introduction of lizards may lead to
Final answer:
The introduction of lizards into a marshy region where small frogs feed on insects may lead to competition for the insects as a food source, potentially affecting the local ecosystem and food webs. Frogs are significant as both predators and indicators of environmental health, and their decline can have wider implications.
Explanation:
The relationship between the small frogs and insects in a marshy region is a predatory relationship, where frogs act as predators feeding on insects which are their prey. When a particular species of lizards, which also feed on these insects, is introduced into the area, this may lead to competition for food resources between the frogs and lizards. This competition could potentially disrupt the existing food webs and lead to decline in insect populations, which in turn can have cascading effects on other species within the ecosystem.
Insects are vital in food chains as they are a primary food source for many species. If their numbers were to decline, the stability of local ecosystems could be at risk. Frogs are important in keeping insect populations under control, but with their numbers declining globally, the introduction of lizards may further strain these populations.
Amphibians like frogs also play a crucial role in ecosystems by indicating environmental health. Declines in their populations usually point to broader environmental issues, which could be exacerbated by the added pressure of competition with the introduced lizards.
The correct answer is option (b). The correct term to describe the relationship between the frogs and insects is a predator-prey relationship.
In ecological terms, when two species (in this case, frogs and lizards) rely on the same limited resources (the insects), they are said to be in competition with each other. This competition can have several potential outcomes:
1) Resource Depletion:
The addition of lizards to the ecosystem increases the total number of predators consuming insects. If the insect population cannot sustain this increased predation pressure, the insect population may decline, potentially leading to resource depletion.2. Competitive Exclusion:
If the lizards are more efficient predators than the frogs, they may outcompete the frogs for the insects, leading to a decrease in the frog population. This is an example of the competitive exclusion principle, which states that two species competing for the same resources cannot coexist indefinitely if other ecological factors are constant.3. Niche Differentiation:
Over time, the frogs and lizards might evolve to partition the resource, with each species specializing in different types of insects, different times of feeding, or different areas within the marshy land. This would reduce competition and allow both species to coexist.4. Trophic Cascade:
The introduction of lizards could potentially lead to a trophic cascade, where changes at the top of the food chain (lizards eating insects) result in changes throughout the food web. For example, if the insect population decreases significantly, this could affect plant life in the marshy region, as fewer insects could mean less pollination or more plant growth if herbivorous insects are reduced.5. Population Fluctuations:
The populations of frogs, lizards, and insects may begin to fluctuate as they adjust to the new equilibrium. These fluctuations can be cyclical or chaotic, depending on various factors such as the reproductive rates of the species involved and the availability of other food sources.The correct answer is:
Small frogs living in a marshy region feed on small insects in the region. a) The relationship between the frogs and insects is a relationship.
b) A particular species of lizards is introduced into the marshy land.
c) These lizards also start feeding on these insects.
d) The introduction of lizards may lead to

The volume of blood filtered by the kidneys is 1.18 dm^3 min^(-1).
Calculate the total volume of blood filtered in 24 hours.
Answer:
1699.2 cubic decimeters
Explanation:
The kidney is the major excretory organ in the human body. It filters the blood and removes waste.
According to the question, the volume of blood the kidney filters is 1.18 dm^3 min^(-1). This means that the kidney filters 1.18 dm^3 of blood per minute. This can be alternatively written as 1.18 dm^3/min
To calculate the volume of blood that will be filtered by the kidney in 24hours, it is necessary to convert 24 hours to minutes.
If there are 60 minutes in 1 hour
Then, there would be 60 × 24 minutes in 24 hours
I.e. there are 1440 minutes in 24hours
Based on this, if the kidney filters 1.18 dm^3 of blood in 1 minute
Then, (1440 × 1.18) dm^3 of blood will be filtered in 1440 minutes (24 hours)
1440 × 1.18 = 1699.2
Therefore, the kidney will filter a total of 1699.2 dm^3 of blood in 24 hours.

Global climate change is the result of increasing levels of carbon dioxide, methane, and other greenhouse gases in Earth's atmosphere. How are the causes of ocean acidification and climate change related to one another?
a) Acids in the ocean decompose to form carbon dioxide, which then diffuses into the atmosphere.
b) Warmer ocean temperatures increase the stability of carbonic acid and other acids in the water.
c) Carbon dioxide diffuses from the atmosphere to the ocean where it reacts to form carbonic acid.
Answer:
c
Explanation:
Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
An increase in greenhouse gases majorly due to human activities is causing Global warming. Deforestation and increase pollutants in water, land and air altogether are the reason for global warming.
The correct answer is:
Option c) Carbon dioxide diffuses from the atmosphere to the ocean where it reacts to form carbonic acid.
The explanation for the statement is:
Global warming has increased the carbon dioxide, methane and other harmful chemicals in the environment.The use of chemicals like CFCs, the release of smoke from factories, nuclear wastes have caused the heat to be trapped on the Earth surface, therefore increasing the planet's temperature.Due to excess carbon dioxide present in the environment and on the surface of the ocean, it gets absorbed and causes acidification of the oceans.Therefore, carbon dioxide diffuses in the ocean and forms carbonic acid.

plz put brainiest if it helped you if not its ok
Lobe-finned fish were ancestors to amphibians and consequently to reptiles, birds, and mammals. The two surviving groups are coelacanths and lungfish, which have fins with bone and muscle, foreshadowing the limbs of terrestrial vertebrates.
Lobe-Finned Fish and Their Descendants
Lobe-finned fish, which fall under the clade Sarcopterygii, are known for their distinctive fins that are fleshy and lobed, supported by bone. Some of the ancestral lobe-finned fish gave rise to forms that eventually evolved into modern tetrapods. These tetrapods include groups such as amphibians, reptiles, birds, and mammals. Unlike their cousins, the Actinopterygii or ray-finned fish, which include species like tuna, bass, trout, and salmon, lobe-finned fish have a richer evolutionary history that traces back to the early evolution of these significant land vertebrates.
The two groups of lobe-finned fish that have survived to the present day are the coelacanths and the lungfish. Originally thought to be extinct, coelacanths made a spectacular re-emergence in scientific awareness when a living specimen was discovered off the east coast of Africa in 1938. Lungfish are found in various places around the world, including Africa, South America, and Australia. Both groups exhibit the characteristic stump-like appendages of bone and muscle in their fins that served as the evolutionary precursor to the legs of amphibians and lungs.
Parathyroid hormone: a. increases osteoblast activity to release more calcium ions into the bloodstream b. increases osteoclast activity to release more calcium ions into the bloodstream c. increases osteocytes activity to release more calcium ions into the bloodstream d. none of the above
Answer:
B
Explanation:
The parathyroid releases hormone that breaks down the bone to raise blood calcium level. Osteoclasts are responsible for breaking down the bone tissue.
Parathyroid hormone increases the blood calcium level by stimulating osteoclast activity, enhancing calcium absorption in the intestines, and reducing calcium loss through urine. It plays a crucial role in maintaining calcium homeostasis in the body.
Explanation:The correct option is b. increases osteoclast activity to release more calcium ions into the bloodstream. Parathyroid Hormone (PTH) is primarily responsible for increasing the blood calcium level. It achieves this by stimulating the activity of osteoclasts, which are cells that degrade bone to release calcium. Additionally, PTH indirectly increases calcium absorption in the intestines by enhancing the synthesis and secretion of calcitriol (an active form of Vitamin D) in the kidneys. This hormone also facilitates the reabsorption of calcium in the kidney tubules, thus reducing the loss of calcium through urine, further maintaining calcium homeostasis in the body.

Answer:
renal threshold
Explanation:
The concentration of a particular substance that is dissolved in the blood above which the substance is removed from the body in the form of urine is known as renal threshold. The renal threshold of different substances varies as the ability to hold diferent substances varies by the kidney. Along with the substance, the physiological conditions and the species also influence the renal threshold. If the renal threshold for a substance is lowered then lower blood levels compounds will be excreted out and if the threshold is higher then opposite will occur.Suppose a study finds a negative correlation between levels of a particular enzyme in the brain and the severity of mania in people suffering from bipolar disorder.
