Which describes heritable
variation?
Answer:
the answer is D.
Explanation:
The heritable variation is defined as the variance of the breeding values among individuals.
Sexual reproduction describes heritable variation.
What is heritable variation?
Life on Earth is being shaped in large part through genetic selection. According to traditional genetic theory, a trait's response to selection is the result of the trait's additive genetic variance and the strength of the selection process.
The innate ability of a population to adapt to selection is reflected in the additive genetic variance. However, the social structure of life is ignored by the typical additive genetic variance.
A broad definition of heritable variation is, however, lacking in models that take indirect genetic effects into account. Here, I offer a broad definition of the heritable variation that affects a population's capacity to adapt to selection.
Therefore, Sexual reproduction describes heritable variation.

Explain how these geological processes and interactions have changed Earth's surface through the years. Be sure to use evidence to support your answer.
Convergent, divergent, and transform boundaries are the processes which make changes in the shape of the earth.
What types of geological events or changes occur at divergent plate boundaries?Earthquakes and magma eruption from the Earth's mantle to the surface and creation of new oceanic crust are the types of geological events that occur at divergent plate boundaries.
What types of geological events or changes occur at convergent plate boundaries?Earthquakes, volcanoes, the formation of mountains, and other geological events are the types of geological events or changes occur at convergent plate boundaries.
What types of geological events or changes occur at transform plate boundaries?Shallow earthquakes, large movement of rock, and crustal deformation are the types of geological events or changes occur at transform plate boundaries
Explain how these geological processes and interactions have changed Earth's surface through the years.Wind, water, and ice changed shape of the land. Volcanic activity and earthquakes also change the landscape in a violent manner. With passage of million of years, the movement of earth's plates slowly reconfigures oceans and continents.

The processes that affect the shape of the planet are known as convergent, divergent, and transform boundaries.
At divergent plate borders, geological phenomena such as earthquakes, magma eruption from the Earth's mantle to the surface, and the formation of new oceanic crust occur.
How geological processes and interactions have altered the Earth's surface over time?The land was shaped by wind, water, and ice. Volcanic eruptions and earthquakes wreak havoc on the terrain as well. The movement of the earth's plates steadily reconfigures oceans and continents over millions of years.
Geological occurrences or changes at transform plate borders include shallow earthquakes, substantial rock movement, and crustal deformation.

Many cancer-fighting drugs work by disrupting the cell cycle. If a drug works
by disrupting mitosis, which cells are most likely to be affected?
A. Red blood cells, which cannot divide
B. Actively dividing cells
C. Brain cells, which rarely divide
D. Cells in G0phase
Answer:
B
Explanation:
The cell cycle goes from the resting phase, through active growing phases, and then to mitosis (division). The ability of these pharmaceuticals to kill cancer cells depends on its ability to halt cell division. Usually, cancer drugs work by damaging the RNA or DNA that tells the cell how to copy itself in division.
This means the cells most likely to be affected are the ones that frequently divide, or actively dividing cells.

In the carbon cycle, plants, animals and fungi are considered in fungi.
What are the characteristics of carbon cycle?The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of Earth.
The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.
The carbon cycle depicts the natural flow of the element carbon through the atmosphere in different forms. There are six main processes in the carbon cycle: photosynthesis, respiration, exchange, sedimentation, extraction, and combustion.

8. Suppose this mating pattern continues among scrub jays for several generations, what do you predict will happen to the number of jays with medium-length bills
in the population? Why? Explain in your answer the relation between reproductive success and the transfer of traits from one generation to the next
Can somone answer question 8 .
Answer:
Island scrub-jays mated nonrandomly with respect to bill length. Each point represents a pair of breeding birds (n = 42). All individuals were measured as adults. The same result was obtained when controlling for body size.
Regarding bill length, island scrub-jays married in a non-random manner. A breeding pair of birds is represented by each point (n = 42). We measured everyone as an adult. When body size was taken into account, the same outcome was achieved.
What is natural selection?Populations of living things adapt and change through a process called natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways.
This variety indicates that some people have characteristics that are more environment-appropriate than others. The ability to convey genes to the following generation in a way that allows them to do the same is referred to as reproductive success.

i don't know pay more attention in class
Explanation:
you got this I believe in you
Answer:
A, B, B.
Explanation:
Imagine you are studying a population of finches on one of the Galápagos Islands. You have been recording many of the birds’ physical traits, including the length of both wings. You observe that for 80% of individuals measured, the length of the left wing is not significantly different from the length of the right wing (in other words, they are symmetrical). But for about 20% of birds measured, the wing lengths are asymmetrical. This distribution is true from generation to generation. Suddenly, a rare 5-day windstorm takes over the island. After the storm, you spend the next several days netting each bird on the island that survived the storm. You discover that 85% of the birds with symmetrical wings survived the storm, whereas only 5% of the birds with asymmetrical wings did.
Propose a hypothesis to explain this observation.
Answer:
Hypothesis: Birds with asymmetrical wings are more likely to have difficulty flying whilst in a storm than birds with relatively symmetrical wings.

Fats are generally: Solid at room temperature and from animal sources
What are fats?
Along with protein and carbohydrates, fat is a macronutrient that can be found in food. Chemically identical compounds made of fatty acids make up fats. They include solid fats like butter, vegetable shortening, ghee, and lard as well as liquid oils like olive oil.
Fish and a wide variety of plants both produce oils. However, due to their high content of saturated fatty acids, tropical oils like coconut, palm, and palm kernel are solid at room temperature. As a result, they are categorized as a solid fat as opposed to an oil.
Oils are generally: Liquid at room temperature and from plant sources.

if no conclusions can be drawn from the data
if results are the same after repeating the procedure
Answer:
d
Explanation:
the situation which would be least likely for a scientist to revise our experimental method would be if results are the same after defeating the procedure.
In the following situation, it would be least likely for a scientist to revise her experimental methods, If results are the same after repeating the procedure, that is the last option.
What is the repetition in the scientific experiment?When the hypothesis or data from a scientific experiment do not match the expected data, scientists are more likely to repeat the experiment and when the result remains the same after many repeatation, scientists are less likely to repeat the experiment. Many experiments are replicated with new technologies in order to obtain a new result, so repeats are quite common in scientific experiments to check the facts and findings.
