Answer:
Blood goes from small intestine to the liver in order to remove toxic substances and store the nutrients. After that, the blood is sent to all parts of the body.
Explanation:
Liver is an important organ of the body which is responsible for the purification of blood coming from the small intestine and then it send to all organs of the body. This blood contains nutrients which is absorbed in the small intestines and some toxic substances which is purify by liver.
Emily (who is 5.5 feet tall) wants to measure the height of a tree in the
forest near where she lives since there is a big storm approaching and she
is worried that it might fall over and hit her house if it is too tall. If she can
see the top of the tree at an angle of 46.4 degrees and if she estimates the
distance between her house and the tree to be 100 feet, is the tree tall
enough to hit her home?
Answer:
YES
Explanation:
Here apply the formula for tangent of an angle to find height of the tree
Distance from house to tree is 100 ft = adjacent side
Tan ∅ = opposite side/adjacent side
Tan 46.4° = height of tree/100
h= 100 tan 46.4° = 105.01 ft
Given height of Emily is 5.5 ft, add this to 105.01 to find total height of the tree
=105.01 + 5.5 =110.51 ft
The tree is tall (110.51 ft) enough to hit her home which is 100 ft away from the tree.

Wyatt and Darnell are designing an experiment to study water mold reproduction. Water mold is an example of a protist that reproduces both sexually and asexually in a process called alternation of generations. Look at the diagram of the water mold life cycle. At which point is genetic information combined?
In water molds, and other protists exhibiting alternation of generations, genetic information is combined during sexual reproduction, specifically when haploid gametes fuse to form a diploid zygote. Binary fission, multiple fission, and budding represent asexual reproduction where no genetic information is combined.
Protists exhibit diverse reproductive strategies, including both asexual and sexual reproduction. Asexual reproduction in protists can occur through binary fission, multiple fission, or budding, which results in offspring that are genetically identical to the parent. On the other hand, sexual reproduction involves the combination of genetic material from two parents to produce offspring with genetic variation.
In the context of the water mold's life cycle, genetic information is combined during the process of syngamy, where two haploid cells, typically in the form of spores or gametes, fuse to form a diploid zygote. This diploid stage undergoes meiosis to generate new haploid cells that can either grow into new organisms or, under stressful conditions, form cysts that are resistant to harsh environmental factors.
The water mold Saprolegnia is a coenocytic organism that is predominantly diploid. The fusion of a sperm from the antheridium with an egg from the oogonium results in the combination of genetic information, leading to the formation of a diploid zygote. Afterward, this zygote undergoes meiosis and returns to a haploid state, completing the cycle of alternation of generations.

Explanation:
The one that is not an invasive species would be that tomato plants brought into a garden and given the opportunity to grow and thrive without any harm to any other plant species. In order to be invasive, a species must be introduced,have no natural predators or competitors, reproduce rapidly, and cause a problem to the native species. All of these are example of species that have been introduced and have led to environmental problems except the example with tomatoes.

What pattern is described by the theory of punctuated equilibrium? Punctuated equilibrium
Answ
paces of species
Explanation:
The theory of punctuated equilibrium in evolutionary biology posits that long periods of stability in species are interspersed with brief phases of rapid evolutionary change. This concept, proposed by Eldredge and Gould, contrasts with gradualism, which argues for steady evolutionary change over time.
Understanding Punctuated Equilibrium
The theory of punctuated equilibrium describes a pattern in the evolutionary process. According to this theory, the evolution of species is marked by long periods of relative stability or stasis, interrupted by short, but significant phases of rapid evolutionary change. This model contrasts with gradualism, which suggests that evolutionary change occurs slowly and steadily over time. The concept of punctuated equilibrium was first proposed by paleontologists Niles Eldredge and Stephen Jay Gould in 1972.
Drawing from fossil records, this model observes that species often remain unchanged for extended intervals—a phenomenon known as stasis. Evolutionary transformations appear more abrupt in geological terms, happening over thousands or maybe a few million years, which still seems sudden compared to the lifespan of most species. This rapid change is usually associated with speciation events, where new species are formed.
Therefore, punctuated equilibrium is a model of the timing of evolution, highlighting how long periods of little evolutionary change are punctuated by bursts of rapid evolutionary change. It's important to note that these periods of rapid change are not instantaneous but are rapid in comparison to the long periods of stasis that precede them.
Plants have large central vacuole. What is the function of the central vacuole in plants?
Answer:
To store things in the cell.
Explanation:
Answer:
Storage.
Explanation:
In plants, a large central vacuole is usually found in a mature cell. It is lined with a membrane and filled with the cell sap. Cell sap acts as a store house for many substances including excretory products.
They are located in both animal and plant cells and are way larger in plant cells. Vacuoles stores food and different varieties of nutrients, a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination.

1. What are the benefits and costs of renewable and nonrenewable resources?
Answer:They include fossil fuels such as oil, natural gas, coal, and uranium used for nuclear energy. Despite this, they have a couple of advantages: The main advantages of non-renewable energies is that they are abundant and affordable. ... Non-renewable energy is cost effective and easier to product and use.
Explanation:
Renewable resources have the benefits of being replenished naturally and having a lesser environmental impact. However, the costs involve initial investment and infrastructure while nonrenewable resources have limited reserves and long-term costs.
Explanation:The benefits of renewable resources include their ability to be replenished naturally and their lower environmental impact compared to nonrenewable resources. Renewable resources, such as wind, water, geothermal, and solar power, do not deplete over time and contribute less to global warming. On the other hand, nonrenewable resources, like fossil fuels and nuclear power, have limited reserves and can have negative environmental consequences.
The costs of renewable resources primarily involve the initial investment in infrastructure and technology needed to harness and utilize these sources of energy. However, over time, the costs of renewable energy have been decreasing as technology advances and economies of scale are achieved.
Nonrenewable resources, although currently more affordable due to existing infrastructure, have long-term costs associated with their depletion, environmental impact, and potential hazards, such as nuclear waste disposal.

Explanation:
A fly has two alleles for the color of its eyes. The green allele is recessive, and
is represented by q. The blue allele is dominant, and is represented by p. If 29
of 100 organisms are green, what is q?
Homozygous dominant + Heterozygous + Homozygous recessive = 1
p+ 2pq + q^2 = 1
A. 0.71
B. 0.46
C. 0.29
D. 0.54
The equations of the Hardy-Weinberg equilibrium are useful to get allelic and genotypic frequencies. In the example q = 0.538 ≅ 0.54 . Option D. 0.54
What is the Hardy-Weinberg Equilibrium?
The Hardy-Weinberg equilibrium theory states that allelic and genotypic frequencies remain the same through generations in a population that is in equilibrium.
Assuming a diallelic gene,
The allelic frequencies in a locus are represented as
The frequency of the dominant allele f(X) is pThe frequency of the recessive allele f(x) is qThe genotypic frequencies after one generation are
p² (H0m0zyg0us dominant genotypic frequency), 2pq (Heter0zyg0us genotypic frequency), q² (H0m0zyg0us recessive genotypic frequency).The addition of the allelic frequencies equals 1
p + q = 1.
The sum of genotypic frequencies equals 1
p² + 2pq + q² = 1
In the exposed example, the gene coding for eye color is diallelic.
B is dominant and codes for blueb is recessive and codes for greenN = 100 individuals
Green eyed individuals = 29
Blue eyed individuals = 71
The frequency of green eyed individuals is 29/100 = 0.29 ⇒ q²The frequency of blue eyed individuals is 71/100 = 0.71 ⇒ p² + 2pqIf q² = 0.29, then
q = √0.29
q = 0.538
If q = 0.538, then the value of p can be calculated by clearing the following equation
p + q = 1
p + 0.538 = 1
p = 1 - 0.538
p = 0.462
We can use the p value to calculate p²
If p = 0.462, then
p² = 0.462²
p² = 0.2134
And the frequency of the heter0zyg0us genotype is
2pq = 2 x 0.462 x 0.538
2pq = 0.497
p² + 2pq + q² = 1
0.213 + 0.497 + 0.29 = 1
The frequency of the recessive allele is q = 0.538.

A species of fly lacks wings. How would biologists explain how a species of fly without wings evolved from an ancestral fly species with wings ?
Answer:The species of fly did not need the wings because of its specific environment.The species of fly did not need the wings because of its specific environment.
Explanation: The species of fly did not need the wings because of its specific environment.
The species of fly did not need the wings because of its specific environment.
Biologists can explain how a species of fly without wings evolved from an ancestral fly species with wings through environmental adaptedness.
Environmental change is any change in an ecosystem or environment that warrens adaptability from the inhabiting organisms in order to survive. The ability to adapt to these changes is known as environmental adaptedness. This is a form of evolution in which an organism will generate or loose characteristics in response to changes in its way of life.
Biologist can explain how a species of fly without wings evolved from an ancestral fly species with wings through environmental adaptedness because the presence of unnecessary wings would have caused the expenditure of energy with no benefit to the fly, therefore, the offspring of a fly who lives in an environment which has no need for the ability to fly will gradually loose their wings in order to retain more energy and function more efficiently. This is evolution through environmental adaptedness.

Hydrolysis of polymer will produce ?
Answer:
Monomers.
Explanation:
The process of hydrolysis, reactions tends to breakdown polymers into monomers when they react with water, this process is easily seen as the opposite of dehydration synthesis which only forms water during polymer synthesizing from monomers. Hydrolysis also breaks bonds and release energy during the course of its reactions.
The formed synthesis here, is described as a molecule that forms the basic unit for polymers, they form the basic structures of proteins. Monomers also tend to bind with other monomers to form cycles of chain molecules through polymerization.
The hydrolysis of a polymer typically yields monomers, the initial small molecules that made up the polymer. This happens through the breaking of bonds in the polymer chain, facilitated through the addition of water.
Explanation:The hydrolysis of a polymer typically produces monomers, the small molecules from which the polymer was originally formed.
This process involves the breaking of bonds in the polymer chain, facilitated by the addition of water. For instance, when a polyester polymer undergoes hydrolysis, it produces monomers like carboxylic acids and alcohols. Similarly, the hydrolysis of a protein, which is a peptide polymer, generates amino acids.

What molecular clock might be useful to examine the evolutionary relationship
between several phyla in the Plant Kingdom? Explain your answer. *
Final answer:
The DNA sequence-based molecular clock is useful to examine the evolutionary relationship between several phyla in the Plant Kingdom.
Explanation:
A molecular clock that might be useful to examine the evolutionary relationship between several phyla in the Plant Kingdom is the DNA sequence-based molecular clock.
This molecular clock compares the DNA sequences of different plant species to estimate how long it has been since these species diverged from a common ancestor. It is based on the assumption that mutations accumulate at a steady rate in a given region of DNA over time. By comparing the number of DNA sequence differences between species, scientists can determine the level of relatedness and the time of divergence.
For example, if two plant species have fewer DNA sequence differences, it suggests a more recent common ancestor, indicating a closer evolutionary relationship. On the other hand, if two plant species have more DNA sequence differences, it suggests a more distant common ancestor, indicating a more distant evolutionary relationship.

Elizabeth and Benjamin are investigating the forces that result from electric charges. They rub inflated balloons with wool cloth. Which of the following observation supports the claim that the balloons have the same electric charge?
A)Not all the balloons were rubbed with wool.
B)The balloons were all about the same size.
C)The balloons repelled each other without touching.
D)The balloons are made of thin material.
Answer: Option C.
The balloons repelled each other without touching.
Explanation:
The balloons repelled each other without touching is an observation that the balloons has electric charge.
Electric charge is of an object either positive or negatively charge.
The balloons are positively charged that is why they repel each other. The objects that are positively charged repel each other. That is positively charged ballin will exert a repulsive force against another positively charged balloon.
Final answer:
The observation that supports the claim that the two balloons have the same electric charge is that they repel each other without touching, indicating they are both negatively charged due to the transfer of electrons from the wool cloth. (option C)
Explanation:
When Elizabeth and Benjamin investigate the forces that result from electric charges, they discover that when two balloons rubbed with wool cloth repel each other without touching, this observation supports the claim that the balloons have the same electric charge.
This phenomenon is explained by the principle that like charges repel each other, which is a basic concept in static electricity.
In the PhET Explorations simulation 'Balloons and Static Electricity', it is possible to visualize how rubbing the balloons with a sweater transfers negative charges to the balloon, and similarly charged objects will repel each other, just as the balloons do after being rubbed with wool.

b) I think I would be able to do this within two months. I say within two months because trust takes time to build and animals comfortably level next to each other also takes time to build. They should be able to stay a whole night in the same area without fighting.
c) Wolves and dogs are similar in this case because its up to the female when she is ready to mate with the male. And sometimes the female might not want offspring with a certain male of the group but with a different one. It's also different because with wolves, they want to eat you. With dogs, trust can grow to the point of rolling in the mud together and tolerate you and other humans.
d) Cats are unpredictable. You can cuddle one moment and it scratch you the next out of nowhere. It probably did give off signs of it not wanting to be in the mood that you missed. And female cats might have the same problem of wanting to choose it mate. And they are not similar to a wolf or dog. Dogs and wolves howl and cat meow.
