Answer:
There's two possibilities, either nothing happens, or they are slowly eliminated from the population.
Explanation:
Some adaptations are no longer useful, like wisdom teeth for us humans or hip bones in whales. Whales definitely don't need hip bones, but having them also doesn't really hurt their chances of survival. In these cases it doesn't matter, so the individuals remain in the population.
If the organism's chance of survival is decreased due to its adaptation no longer working, then it will be eliminated from the population through natural selection. For example, if an individual's camouflage stops working, they will be less likely to survive and reproduce.
Differences in traits such as hair texture are determined by differences in ? A) The location of sugar groups in DNA B)the sequence of nucleotides in DNA C) The number of nitrogenous bases un DNA D)The molecules attached to the phosphate in DNA
Answer:
A
Explanation:
This is called the locus and is determined in Meiosis by gametes from parent cells. During meiosis there is this thing called 'crossing over' where the gametes (sperm and egg cells) homologous genes (genes of similar size and shape, such as X and Y chromosomes or X and X) exchange genes on the same locus to provide slightly different characteristics.

D. Grassland
Answer:
Option C is the correct answer
Explanation:
We could call this a wetland community. Compare this community to an ecosystem. Differentiate one more important difference between the organization of the two?
Interactions in a community occur only between living creatures or biotic components. Interactions take place in an ecosystem between living components as well as between non - living and living components.
What is a wetland community?Wetland communities are aggregations of individuals from various species (plants, animals, microorganisms) that live and interact in habitats with water at or near the ground's surface or where the land is inundated by shallow water for large portions of the year.
Wetlands are locations where water covers the soil or is present at or near the soil's surface all year or for a variety of times throughout the year, including the growing season.
In a community, interactions occur between only biological organisms or biotic components.
Interactions occur in an ecosystem between living and non-living components as well as between living and non-living components.
Thus, this is the basic difference between the organization of the two.

A woman buys a packet of seeds for red flowering plants. In the spring, she plants the seeds in her garden and enjoys beautiful red flowers all summer. The flowers are self-pollinating, and many of the flowers produce seeds. The woman collects these seeds and plants them in her garden the following spring. She is surprised when about one-fourth of these plants produce white flowers while the other three-fourths produce red flowers. Assuming that the seeds were all produced by self-pollination of the parental generation, which statement best explains the reason for the woman’s observations?
A. Temperatures were above average in the garden, causing only red flowers to be produced in the first year and both white and red flowers in the second year.
B. Some of the seeds were exposed to conditions that caused a change in the plant’s genes, leading to the production of white flowers instead of red flowers in plants grown from these seeds.
C. Both the white and red flower traits were present in the parental generation, but only the red trait was expressed in this generation, while both traits were expressed in the next generation.
D. Offspring acquired new genes during the crosses taking place between plants in the parental generation, and one of these genes codes for the white flowering trait.
E. Plants producing white flowers in the second generation did not receive the same essential nutrients from the soil needed to produce red flowers.
Answer:
It should be C -
Both the white and red flower traits were present in the parental generation, but only the red trait was expressed in this generation, while both traits were expressed in the next generation.
Explanation:
The reason is just like human. As an example, a family of, let's say Africa, and all of them are dark skin, then one married to a, let's say Europe, and that person is light skin. Which the offspring became a pretty dark skin. Then as the offspring grow up and have family of their own, the trait of light skin is always in the family, although it is recessive. So randomly, that light skin gene will pop-up in the generation, probably just not in this one.

Review Answer Selections
Answer:
D
Explanation:
DNA pairs with adenosine, thymine, cytosine, and guanine
RNA pairs with uracil, adenosine, cytosine, and guanine
Option D is correct because RNA pairs uracil with adenine instead of thymine, unlike DNA. Other differences include ribose in RNA versus deoxyribose in DNA and RNA being single-stranded while DNA is double-stranded.
The correct answer to the question is Option D: pairs uracil with adenosine instead of thymine.
A. has deoxyribose as the sugar within its nucleotide components: This statement is incorrect because RNA contains ribose, not deoxyribose. Deoxyribose is found in DNA.B. contains two strands wrapped in a helix: This is incorrect because RNA is typically single-stranded, whereas DNA is double-stranded.C. contains nitrogenous bases: While this is true for both RNA and DNA, it does not 'unlike' DNA. Both types of nucleic acids contain nitrogenous bases.D. pairs uracil with adenosine instead of thymine: This is the correct statement. Unlike DNA, RNA uses uracil in place of thymine and pairs it with adenine.In summary, RNA and DNA differ primarily in their sugars (ribose vs. deoxyribose), the presence of uracil instead of thymine, and RNA being single-stranded compared to the double-stranded DNA.

Explain how a cold front is formed.
Explanation:
Cold fronts form when a cooler air mass moves into an area of warmer air in the wake of a developing extratropical cyclone. The warmer air interacts with the cooler air mass along the boundary, and usually produces precipitation. Cold fronts often follow a warm front or squall line.
Cold Front: transition zone from warm air to cold air. A cold front is defined as the transition zone where a cold air mass is replacing a warmer air mass. Cold fronts generally move from northwest to southeast. The air behind a cold front is noticeably colder and drier than the air ahead of it.

function of diastema in herbivores
Answer:
Gnawing and chewing of plants.
Explanation:
Diastema are spaces found in the dentition of most mammals or any organism that has teeth. It is a space separating dentition for different functions, specially that amongst the biting tooth and grinding tooth. Rabbits are been used as a case study because they are herbivores and also don't have canines, so the diastema helps with gnawing and chewing of plants.
It is well known according to study that a great number of herbivores have no canine, so the diastema aids in holding, gnawing and chewing of plants. This is really helpful, considering rabbits are herbivores.
What’s the difference between a red deer, roe deer, chamois, and ibex?
Answer: Male ibex, red deer, and roe deer were generally harvested at higher elevations compared to females, whereas female chamois were harvested at higher elevations compared to male chamois. Differences in harvest elevations between males (higher) and females (lower) are smallest for ibex and largest for red deer.
Explanation: Hoped this helped
The red deer is large with prominent antlers, while the smaller roe deer has shorter antlers. The chamois is well adapted to mountains with a robust body and short horns, and the ibex is notable for its large, curved horns and mountainous habitat preference. Human activities have influenced their populations and distributions.
Differences Between Red Deer, Roe Deer, Chamois, and Ibex
The red deer, roe deer, chamois, and ibex are distinct species with unique characteristics. The red deer is known for its size and imposing antlers, especially during the rutting season when the stags roar to assert dominance. Roe deer, by contrast, are considerably smaller, with shorter antlers and more solitary behavior. Chamois are adapted to mountainous terrain, with a robust body and shorter horns that hook backwards. Lastly, the ibex is recognized for its large backward-curving horns and is typically found in rocky, mountainous environments.
Each species occupies a different ecological niche and has distinct adaptations that assist in survival, such as the chamois' agility in rugged terrain and the ibex's ability to scale steep cliffs. All of these species have been affected by human activities, ranging from hunting to habitat changes, impacting their populations and distribution.

Explanation:
Final answer:
José can learn about evolution in detail from the fossil record, understanding the progression and transformation of life over millions of years and gathering evidence for how species have evolved.
Explanation:
Understanding the Fossil Record
Through studying the fossil record, José can learn about the progression of life and the evidence for evolution. By analyzing fossils, which are the preserved remains or traces of organisms, scientists can paint a picture of what life looked like millions of years ago. This helps us understand how species are related, how they have changed over time, and when they lived. For instance, the comparison of the morphology of a whale flipper with that of bird and mammal appendages can provide evidence of a common ancestor, illustrating the concept of evolutionary change over time.
Fossils provide solid evidence that past organisms are distinct from those found today. The detailed records of fossils, such as those of humans and horses, show evolutionary adaptations and transformations, revealing a history of life that has spanned over four billion years. José can infer the characteristics of extinct species and comprehend the immense time scale involved in the evolutionary process.
1. Look at the illustration in Figure 25-4. Do you think that the bud on the side of the adult hydra
is an embryo? Why?
A. No, because budding is a type of asexual reproduction.
B. No, because budding is a type of sexual reproduction.
C. Yes, because budding is a type of asexual reproduction.
D. Yes, because budding is a type of sexual reproduction.
Answer:
A. No, because budding is a type of asexual reproduction.
Explanation:
Asexual reproduction is the process where an organism makes a copy of itself by itself. It does not require a mate to make offspring.
The offspring are genetically identical to the parent.
Budding is a type of asexual reproduction where a small outgrowth of the parent breaks off to become a new organism.
Embryo development is usually only discussed in the context of sexual reproduction, where two gametes fertilize one another and a new organism that is genetically different to either parent is formed.
Answer:
A. No, because budding is a type of asexual reproduction.
Explanation:
The buds on the side of the adult hydra is not an embryo because budding is a type of asexual reproduction.
It is sexual reproduction that produces an embryo from the fusion of gametes.
Hydra produces new ones by budding using part of its body wall. This process is simply an outgrowth from the body wall. An embryo is one of the stages of development of offspring originating from a zygote. It is begins at fertilization to the formation of body structures. Embryos are peculiar to organisms that reproduces sexually.How many diseases are created each year

Describe how the motion of Earth is affected by the sun. Be sure to include the direction of any force you identify and the shape of the path that results.
The effect of motion of Earth by the sun is given below.
Explanation:
1. The Earth rotates once on its axis about every 24 hours. If you were to look at Earth from the North Pole, it would be spinning counterclockwise. As the Earth rotates, observers on Earth see the Sun moving across the sky from east to west with the beginning of each new day. We often say that the Sun is "rising" or "setting", but actually it is the Earth's rotation that gives us the perception of the Sun rising up or setting over the horizon. When we look at the Moon or the stars at night, they also seem to rise in the east and set in the west. Earth's rotation is also responsible for this. As Earth turns, the Moon and stars change position in our sky.
2. Tides are the regular rising and falling of Earth's surface water in response to gravitational attraction from the Moon and Sun. The Moon's gravity causes the oceans to bulge out in the direction of the Moon. In other words, the Moon's gravity is pulling upwards on Earth's water, producing a high tide.
3.The Moon's position in its monthly orbit determines how it appears from Earth. The diagram on page 725 shows how the positions of the Moon, the Sun, and Earth affect the shapes you see in the sky. ... As the Moon moves along its orbit, sunlight begins falling on the near side. You see a thin crescent shape.
The Sun's gravity influences the Earth's motion, causing it to orbit in an elliptical path around the Sun. The direction of Earth's rotation affects the apparent motion of the sun and causes a deviation in the path of large scale movements like weather systems, known as the Coriolis effect.
Explanation:The motion of the Earth is greatly influenced by the gravitational pull from the Sun, causing the Earth to move in a consistent, elliptical path around the Sun. This elliptical orbit is referred to as the ecliptic. Viewed from above the North Pole, Earth rotates in a counterclockwise direction.
This rotation leads to a phenomenon known as the Coriolis effect. In the Northern hemisphere, this effect causes moving air and water to appear to turn right. In the Southern Hemisphere, the effect is reversed, causing motion to turn left. These effects caused by Earth's rotation impact large scale motions, such as weather patterns.
The direction of Earth's rotation also affects the Sun's apparent motion in the sky. Due to the ecliptic and Earth's tilt, the Sun seems to move north and south as the seasons change. Additionally, because of Earth's constant motion, the Sun rises about 4 minutes later each day in relation to the stars.

Well for me, I think i'd say CAT TRAINING.
Here's an example. My newest cat is still learning how to come to the food in the kitchen, and come at times when she needs to eat even if already eaten in the morning.
So before today, I've been trying to get her to come just by placing the food down. But she doesn't give a response to it. Next I try a bell alone, and some other jingling or noise makers. Still no response of her coming to me at all. Then I tried placing the food down while ringing the bell, she's starting to understand, but still not a very good response. I assume in a few more days, she will understand that the bell/other noise means COME TO ME. That is a conditioned response i'm hoping to get soon.

What other illness played an important role in the development of a vaccine for smallpox?
a. Measles
b. Bubonic Plague
c. Polio
d. Cow pox
e. HPV
Answer:
A.Measles
Explanation:
The origin of smallpox is unknown. Smallpox is thought to date back to the Egyptian Empire around the 3rd century BCE (Before Common Era), based on a smallpox-like rash found on three mummies. The earliest written description of a disease that clearly resembles smallpox appeared in China in the 4th century CE (Common Era). Early written descriptions also appeared in India in the 7th century and in Asia Minor in the 10th century.The smallpox vaccine was the first vaccine to be developed against a contagious disease. In 1796, the British doctor Edward Jenner demonstrated that an infection with the relatively mild cowpox virus conferred immunity against the deadly smallpox virus.
