Answer:
Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.
The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.
What is dehydration?Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.
The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration. It makes the kidney to filter less water.
Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

explain absorption of food
Key Points
Digested food is able to pass into the blood vessels in the wall of the small intestine through the process of diffusion.
The inner wall, or mucosa, of the small intestine is covered in wrinkles or folds called plicae circulares that project microscopic finger-like pieces of tissue called villi, which in turn have finger-like projections known as microvilli.
The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients.
Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.
Key Terms
villi: Tiny, finger-like projections that protrude from the epithelial lining of the intestinal wall.
plicae circulares: These circular folds (known as the valves of Kerckring or the valvulae conniventes) are large, valvular flaps that project into the lumen of the bowel.
diffusion: The act of diffusing or dispersing something, or the property of being diffused or dispersed; dispersion.The Small Intestine
The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food.Digested nutrients pass into the blood vessels in the wall of the intestine through a process of diffusion. The inner wall, or mucosa, of the small intestine is lined with simple columnar epithelial tissue.
Structurally, the mucosa is covered in wrinkles or folds called plicae circulares—these are permanent features in the wall of the organ. They are distinct from the rugae, which are non-permanent features that allow for distention and contraction.
From the plicae circulares project microscopic finger-like pieces of tissue called villi (Latin for shaggy hair). The individual epithelial cells also have finger-like projections known as microvilli. The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients.
Each villus has a network of capillaries and fine lymphatic vessels called lacteals close to its surface. The epithelial cells of the villi transport nutrients from the lumen of the intestine into these capillaries ( amino acids and carbohydrates) and lacteals (lipids).
The absorbed substances are transported via the blood vessels to different organs of the body where they are used to build complex substances, such as the proteins required by our body. The food that remains undigested and unabsorbed passes into the large intestine.

Because he was well aware of the effect his theory of evolution would have on the public and on the Church of England, Darwin delayed publishing his work for several decades while he gathered additional evidence. After invoking selective breeding of domesticated species as evidence that groups of organisms are capable of change, he then proposed that natural populations can change as well. On which two lines of evidence did he base this proposal? a) Individuals within a population vary, yet island species around the world all appear to be related to each other.b) Organisms produce more offspring than can be supported by their environment, and adaptations to specific environments increase an organism's ability to survive and reproduce.c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.d) Some individuals leave more descendants than other individuals, but the individuals in a population are essentially identical to each other.e) Some individuals within a population have greater success in survival and reproduction than others, and favorable traits within a population will accumulate over generations.
Answer:
c) Organisms within a population vary, and all populations produce more offspring than can be supported by the environment, resulting in competition for survival within the population.
Explanation:
Darwin's theory was based on the evidence of natural selection and survival of the fittest.
Evidence of Darwin's theory were observed from the variation in the population which is supported by the environmental factor (natural selection) and these population than produce offspring, resulting in competition for survival within the population (survival for fittest).
Hence, the correct option is "c".

When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals may form. How is this possible? Two diverged populations are capable of mating and producing viable and fertile offspring. Hybrid individuals may have reduced fitness and thus be strongly selected against. Hybrid individuals are always allopolyploid and are thus unable to mate with either of the original species. One species has a selective advantage, so as hybridization continues, the other species will go extinct.
Answer:
Two diverged populations are capable of mating and producing viable and fertile offspring.
Explanation:
Although the biological concept of species says that two different species can not mate and produce viable fertile descendants, the hybrid zones are characterized for being an area where two different genetically groups meet and reproduce. These groups might be the same or different species.
This is a frequent phenomenon in nature, and widely common geographically and among taxonomic groups. It is not rear that different sympatric populations, with a short time of divergence and similar reproductive strategies, can hybridize and even generate new populations that get reproductively isolated from their parentals.
When talking about sympatry we refer to two similar species that coincide in part or their whole distribution area.
These new populations are even morphologically different from the parental forms, which allow them to colonize new habitats and niches, promoting diversification.
Hibridation zones are very important to conserve, just because they are points of genetic diversity generation and diversification areas.
When the ranges of two different species meet, a stable "hybrid zone" occupied by hybrid individuals can form. This is possible because hybrid individuals are always allopolyploid and therefore are unable to mate with any of the original species, to understand more we need to know that......
Hybrid animalsHybridization, that is, the process through which different species reproduce, generating an offspring, is not considered a very common phenomenon in nature. This is because, in general, species have a distinct number of chromosomes, the cell structures that contain genes. These differences in the number of chromosomes can make the development of the embryo unfeasible, as the alignment of equivalent chromosomes from the female and the male are necessary for the division of the fertilized cell to occur. When this alignment does not occur, the cell does not reproduce and dies. However, in some cases, even with the lack of chromosome pairs, reproduction between different species is successful, generating the hybrid. However, the birth of the individual does not mean that its survival is guaranteed. Often, the hybrid generated is weaker than its parents and does not survive; in other cases, the hybrid can adapt better to the environment than the species that conceived it.
With this information, we can conclude that hybrid animals are a cross between two different species, but this hybrid can have several complications for its survival.

A. Organ, organ system, cell, tissue, organism
B. Cell, tissue, organism, organ, organ system
C. Tissue, cell, organ, organ system, organism
D. Cell, tissue, organ, organ system, organism
The correct order of organization in animals is Cell, tissue, organ, organ system, organism—that is what is written in the option D. The cell is the first to form, followed by tissue, and finally organs and organ systems.
What is the organization of an animal?At the early stage, unicellular individuals were seen, and later, due to development, multicellular individuals were developed. The unicellular organism has only cells, then those cells unite to make a tissue, and in a tissue all the cells have the same function. An example is epithelial tissue, which is made up of many epithelial cells.
Tissues combine to form an organ, and organs combine to form an organ system. An example is an organ such as the liver that is made up of many tissues, but all tissues perform certain functions that are required for the liver, and in the same way, the organ system and the organism are developed.
Hence, the correct order of organization in animals is cell, tissue, organ, organ system, organism—that is what is written in the option D.

Studies of topsoil erosion on Iowa farmland shows that as much as 50 metric tons are lost per hectare during winter and spring rains. This loss is due to the loss of millimeters of soil from across the entire surface of the fields. Which type of erosion would this be?
Answer:
The type of erosion described in the question is called Water Erosion.
Explanation:
Note that the erosion is caused by winter and spring rains.
Water Erosion can happen when raindrops disintegrate the aggregates of the topsoil. The fragments collect into the soil pores and create a coagulating action which makes it difficult for the water to penetrate the soil. The rainwater having increasingly accumulated on the surface flows off along with the topsoil.
This type of erosion can be further aggravated if:
the rainfall is very heavy;the terrain has a steep gradient thus increasing the velocity of runoffthe soil type has a lower capacity to erosionCheers!

2. Which of the following statements is true of persuasive messages?
A. People tune out repetitious messages, so they quickly lose effectiveness.
B. Messages presenting a one-sided argument tend to be more effective than "he said; she said" messages.
C. Messages that offer a remedy for a person's fears tend to be effective.
D. An effective message will reach all audiences, regardless of background.
Answer:
C. Messages that offer a remedy for a person's fears tend to be effective.
Explanation:
The manner in which the message is presented. Presenting two sides of an argument makes the message seem more believable and persuasive than presenting just one side. Such an approach gives the message a sense of being impartial and factual. *Presenting a fear factor also may persuade people. For example, ads for different kinds of medicines present the dangers lurking around us as they offer a remedy.
Repetition. Repeated exposure to stimuli—like ads—is more likely to have favorable effects on attitudes than infrequent exposure. That’s why companies spend lots of money making sure their ads run again and again and why they have their logos and messages on race cars, buses, and billboards. The more often you see or hear a message, the more likely you are to have a positive attitude toward it.
Messages that offer a remedy for a person's fears tend to be effective is true for persuasive message. Therefore, option (C) is correct.
What is a persuasive message?To persuade someone means to move them emotionally or to motivate them to act in a certain way by presenting them with arguments that convince them to accept your viewpoint or act in the way you want them to. A persuasive message can be either spoken or written and is a form of communication that persuades the reader or listener to behave or act in a particular way.
The first step in convincing someone is to motivate them. If persuasion is a process, and the action of your audience (such as purchasing a product or service) is the goal, then motivating them to accept an argument or a series of positions leading to the decision that you want them to adopt is one way to help achieve that goal. If you want them to buy a product or service, for example, this would be an action.
