I don’t understand it, if someone can explain maybe what I have to do and put into each Column or give me the answer either way would help a lot. Thank you.
Answers
Answer:
First, describe each type of evidence (eg. Molecular biology is comparing DNA sequences to determine common ancestry). Then provide examples of how those pieces of evidence support the theory of evolution. For example, for one of the comparative anatomy examples, you could say that organisms that contain similar structures most likely diverged from a common ancestor.
I hope this gets you on the right track.
Explanation:
How do hypothalamus and pituitary glands work together?
Answers
Answer:
The hypothalamus is responsible for maintaining the body's internal balance (homeostasis) by stimulating or inhibiting major bodily functions such as the heart rate and blood pressure, body temperature, fluid and electrolyte balance, appetite and body weight, sleep cycle and function of the gastrointestinal track. The hypothalamus is also considered the master regulator of the endocrine system; Regulatory hormones secreted by the hypothalamus are transported by the hypophyseal-portal system to the anterior and posterior pituitary, prompting the release of secondary hormones that can affect various organ functions.
Explanation:
A research study looked at variations in snail populations in urban areas compared to natural ecosystems outside of the urban development. Urban areas tend to be be warmer, trapping more solar energy and reflecting less light back out of the atmosphere. The study found that brown snails were more commonly found in the natural ecosystem while yellow banded snails were found in the urban, developed areas. Which statement best describes the distribution in the phenotypes for the snails in this scenario?
A) The variations in the snail populations are random and unrelated to the locations.
B) The variation in the snail population is due to sexual reproduction of the snails in the urban development and asexual reproduction of the snails in the natural ecosystem.
C) The variation in the snail population is due to mutations while the distribution of colors in the population is due to genetic drift. The location of the colors is a random process.
D) The variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter colored snails survive with greater frequency in the warmer urban development.
Answers
Answer:
D) The variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter colored snails survive with greater frequency in the warmer urban development.
Explanation:
The distribution in the phenotypes for the snails in this scenario depends on the variations due to mutations as well as the change in temperature in the two areas.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or manifestation of desired characters. Phenotypes may also be known as traits.
The phenotypes of snail may get changes due to mutation which is caused by the high temperature in an urban area. UV light is considered a physical agent of mutation. Hence, the variation in the snail populations is due to mutations while the distribution of colors in the population is due to the changes in temperature in the two areas. Lighter-colored snails survive with greater frequency in the warmer urban development.
Therefore, The distribution in the phenotypes for the snails in this scenario depends on the variations due to mutations as well as the change in temperature in the two areas.

Overfishing is a global problem in which humans harvest certain species of fish, almost to the point of extinction. Many of the fish stocks depleted by overfishing are at the top of the food chain. Why would the overfishing of very large fish cause a decrease in the numbers of small fish?
The small fish are more likely to die from diseases and parasites.
The small fish live in a mutualistic relationship with the large fish.
The small fish have a greater number of medium-sized predators.
The small fish must compete with each other for fewer food sources.

hope it is helpful to you ☺️✌️how the cells in your body are different from one another. Look at the different types of cells above, and make a list of how they differ. After you have made your list, consider why they have these differences.
Answers
Answer: Different cells have different jobs to do. Each cell has a size and shape that is suited to its job. Cells that do the same job combine together to form body tissue, such as muscle, skin, or bone tissue. Groups of different types of cells make up the organs in your body, such as your heart, liver, or lungs.Differentiation means that one cell performs a different function than another cell, depending on where it is in your body. ... All the cells contain the same genetic material and all of them are from one original cell that started as a fertilized egg, but they look different and act different from one another. Under a microscope, fat cells look like bulbous little spheres. Like other cells in the body, each has a cell membrane and a nucleus, but their bulk is made up of droplets of stored triglycerides, each of which consists of three fatty-acid molecules attached to a single glycerol molecule. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. Unlike many other cells, red blood cells have no nucleus and can easily change shape, helping them fit through the various blood vessels in your body. Unlike most other eukaryotic cells, mature red blood cells don't have nuclei. When they enter the bloodstream for the first time, they eject their nuclei and organelles, so they can carry more hemoglobin, and thus, more oxygen. Each red blood cell has a life span of around 100–120 days. Skin cells are specialized to be quickly shed and replaced, and do not have much mitochondria (which helps produce energy). Muscle cells, conversely, have lots of mitochondria because they need energy to produce movement. brainliest??

In a given year, which would result in the greatest increase in population size?
A. high birth rate, high death rate, high immigration, high emigration
B. high birth rate, zero death rate, high immigration, zero emigration
C. zero birth rate, low death rate, zero immigration, low emigration
D. zero birth rate, zero death rate, low immigration, high emigration
Answers
Answer:
B. High birth rate, zero death rate, high immigration, zero emigration
Explanation:
High birth rate would mean more people being born resulting in a higher population. Zero death rate would mean that no one is dying and leaving the population. Immigration means when people come to a foreign country to live there, meaning that the population would grow. Emigration means the opposite of immigration. So that would mean that the people would be leaving your country. Resulting in a lower population. So, B is the correct answer!

Newton’s second law details the relationship between net force, the mass, and the acceleration: The acceleration of an object is in the direction of the net force. The acceleration has a magnitude directly proportional to the magnitude of the net force. The magnitude of the acceleration is inversely proportional to the mass of the object.
