Explain how hormones recognize their target cells

Answers

Answer:

A target cell responds to a hormone because it bears receptors for the hormone. In other words, a particular cell is a target cell for a hormone if it contains functional receptors for that hormone, and cells which do not have such a receptor cannot be influenced directly by that hormone.

In a density-dependent population, an increase in which of the following will most likely lead to an increase in population density?

Birthrate
Carrying capacity
Death rate
Emigration

Answers

Answer:

birthrate

Explanation:

In a density-dependent population, an increase in birthrate will most likely lead to an increase in population density. So, the correct option is A.

What is population density?

Population density is the number of people in a given area of land. It primarily applies to people, yet occasionally it also does to other living things. That is a crucial geographic phrase. The amount of people who live in an area per square kilometer, or even other unit of land area, is referred to as population density.

We must divide the population's number by the area's size to determine the population density. Population Density is therefore equal to the number of people divided by the land area. Square miles or square kilometers should be used as the measure of land area. If we need to calculate the density of a relatively small place, then can use square feet or meters.

Therefore, the correct option is A.

imagine that ou are stduying a very large population of moths that is isolate d from gene flow.A single gene controls wing color.Half of the moths have white spotted wings (genotype WW or Ww) and half of the moths have plain brown wings (ww).There are no new mutations indivisuals mate randomly, and there is no natural selection on wing color.Explain , why any calculation, wether this population is under a hardy weinberg equilibrium

Answers

About the question:

I failed to find the complete question. However, I will explain why this population is considered to be in Hardy-Weinberg equilibrium, and what the destiny of the alleles is.  

Answer:

This population is in equilibrium because it accomplishes all the H-W assumptions for a population in equilibrium. Genetic nor allelic frequencies will change generation after generation. Alleles will remain equal.

Explanation:

Available data:

A single gene controls wing colorHalf of the moths have white-spotted wingshalf of the moths have plain brown wingsW allele is dominant and expresses white wingsw allele is recessive and expresses brown wingsIndividuals mate randomlyNo natural selection

We will know by theory if this population is or is not in equilibrium Hardy-Weinberg if the population is in concordance with the assumptions of the theory. So let us first analyze the Hardy-Weinberg assumptions for a population in equilibrium:

•  Random matings: Any individual get crossed with any other individual

•  No superposed generations: each individual can leave their gametes in the pool only once.

•  No mutations: No mutations originate any new gametes.

•  No migration: No incorporation of gametes from other populations.

•  Infinite population size: the probabilities of randomly taking an A gamete from the pool are p, and the probability of taking a B gamete is q.

•  No natural selection: Each individual has equal surviving and reproducing probabilities as any other, contributing proportionally to the gamete pool.

So, the exposed population

- is isolated, meaning that there is no gene flow from other populations. No new genes will be introduced.

- has no mutations, so no allele will change to express a new form

- individuals mate randomly

- there is no natural selection acting on this group as an evolutive force that might alter the equilibrium.

Genetic nor allelic frequencies will change generation after generation.

In a Hardy-Weinberg population, where allelic frequencies are p and q (assuming a diallelic gene), genotypic frequencies after one generation of random matings are p², 2pq and q². The allelic frequencies, as well as the genotypic frequencies, remain equal after successive generations. Alleles will remain in the population from many generations.

The teacher asked the students to design an experiment that would demonstrate that temperature will affect the pressure of a gas. Which of the following would be a valid experiment that shows the correct relationship between gas temperature and pressure?

A.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. Then they bring the bike inside to a room temperature environment for several hours to warm up and check the pressure again. They find that the tires in the colder temperature showed a low pressure and that the pressure increased after the tires were able to warm up.

B.
The students want to test the air pressure of bicycle tires. They check the pressure of the tires after letting the bike sit outside in very cold, winter weather for several hours. They then bring the bike inside to a room temperature environment for several hours to warm up and then check the pressure again. They find that the colder temperature showed a high pressure in the tires and that the pressure decreased after the tires were able to warm up.

C.
The students wanted to test the air pressure in a plastic bottle of soda by comparing two bottles. They put one soda in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the soda that had been in the freezer had burst, but the one on the counter was easy to squeeze and showed some give. They determined that the cold temperature had increased the pressure of the gas in the bottle causing it to burst.

D.
The students wanted to test the air presssure in a plastic bottle of soda by comparing two bottles. They put one in a freezer for 12 hours and the second soda was left on the counter at room temperature for 12 hours. They found that the pressure of the bottle which was in the freezer had remained the same. The pressure of the gas in the bottle on the counter increased, causing it to push on the sides of the bottle making it harder to squeeze.

20. Frigatebirds have webbed feet and spend much
of their life flying over the ocean but never land in
the water. What does this fact suggest about the
evolution of these physical and behavioral traits?

Answers

Answer:

Evolution changes the abilities of the Frigate birds.

Explanation:

The Frigate birds have webbed feet because they live in the ocean and unable to fly due to its big weight. Before the evolution, the Frigate birds lives in the ocean due to their large body weight but with the passage of time, evolution occurs that leads to formation of flying ability in the bird so now the bird have the old characteristics of their ancestor as well as new abilities in the physical traits of the Frigate birds due to the evolution.

Other Questions
Science is often defined inadequately as an organized body of knowledge. This would make cookbooks, Sears, Roebuck catalogues, and telephone books science, which they are not. Sometimes science is defined simply as rationality, but that would make much of theology and metaphysics science, which they are not. Rationality is logical consistency, lack of contradiction. It is to be distinguished from reasonableness, the quality of a mind open to arguments and evidence opposed to its beliefs: a willingness to reconsider. Rationalists can be quite unreasonable or dogmatic. Rationalist metaphysicians and theologians are often certain about premises which come from intuition or revelation. Even paranoiacs may be thought of as rationalists, for they are commonly most rigorous in reasoning. But their premises, which they cling to in spite of all evidence, are absurd.WHAT SCIENCE ISScience is empirical, rational, general, and cumulative; and it is all four at once. Science is empirical in that all its conclusions are subject to test by sense experience. Observation is the base on which science rests, but scientific observation is more than keeping ones eyes open. It is observation made by qualified observers under controlled conditions of those things which confirm or disconfirm, verify or refute a theory. Sherlock Holmes* could tell by the stains on a vest what a man had eaten for breakfast. From a number of such observations he arrived at a theory about why and how a particular crime was committed. This procedure is excellent for detection but insufficient for science, because it yields only knowledge of particular events. Science would go on to ask why and how crime, not a particular crime, is committed. Science uses facts to test general theories and general theories to make predictions about particular facts.Scientific observations may be made of things as they exist, like the color of an apple or the temperature of the air, or it may be made of what results from an experiment. An experiment is the deliberate manipulation of conditions in order to bring about what we want to observe. If we want to test the hypothesis that a new plastic can withstand two hundred pounds of pressure without crumbling, we may have to create a situation in which such pressure is applied to a piece of the plastic, because it is unlikely that the situation already exists anywhere in the world, or if it does, that all other factors are kept constant. In some sciences, like astronomy, we do not sufficiently control the subject matter to experiment on italthough we do control the conditions of observationand we distinguish those sciences from others, like chemistry, in which experiment is possible, by calling the latter experimental sciences.Although all scientific thought ultimately rests on observation, there are vast portions of it which are entirely rational: analysis of the meaning of terms, deductions from existent theories, explorations of the logical relations among concepts and among theories. Logic is applied to science constantly because logic contains the rules of valid thinking. The application of mathematics is often thought, erroneously, to be an index of the status of any science. Of course, the more it can be applied usefully within a science, the more advanced the science. For mathematics functions both as a language in which scientific laws are stated, giving them the utmost precision, elegance, and economy, and as the basis of measurement. Many of the most significant advances in physics, astronomy, and chemistry have depended on advances in and application of mathematics. Without calculus the work of Isaac Newton would have been impossible. Yet great scientific work in other fields, performed by men like Pasteur, Darwin, and Pavlov (with whose names pasteurization, evolution, and conditioned response in psychology are associated), has used little or no mathematics. In the final sentence of the first paragraph, the authors choose to use the word absurd in order to demonstrate that even sound premises can lead to irrational conclusions demonstrate that even sound premises can lead to irrational conclusions A argue that evidence that seems illogical should not be considered by scientists argue that evidence that seems illogical should not be considered by scientists B emphasize a previous distinction between rationality and reasonableness emphasize a previous distinction between rationality and reasonableness C imply that too much rigor can lead to nonsensical inferences imply that too much rigor can lead to nonsensical inferences D convey disdain for those who display uncertainty about their premises Dante and Tania are both math tutors.
