2.1explain the body's hormonal response to dehydration​

Answers

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.

Summary

The life history of a species is the pattern of survival and reproduction events typical for a member of the species (essentially, its lifecycle).

Life history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction.

One tradeoff is between number of offspring produced and the amount of energy (both physical resources and parental care) put into each offspring.

The founder effect occurs when Multiple Choice large groups of individuals leave their home population and establish new settlements, mating only among themselves. small groups of individuals leave their home population and establish new settlements, mating only among themselves. many members of a population die, resulting in a great loss of genetic diversity. many members of a population reproduce causing too much genetic diversity within the population. small groups of individuals leave their home population and join established settlements, and mating with natives.

Answers

Answer: small groups of individuals leave their home population and establish new settlements, mating only among themselves.

Explanation:

The founder effect is what happens when a small group of individuals leave their home population in order to establish new settlements. They will then mate only amongst themselves and colonize the area without mixing with the natives.

As a result of the founder effect, there is less genetic variation in the new population than in the home one because the smaller number of individuals who left would not possibly be able to carry all the genes in the home population. The only genes that would be passed on are those of the small individuals.

The teacher was unaware of the difference between suspension feeding and predation.

Consequently, which two organisms would have been among the first to starve to death (assuming they lack photosynthetic endosymbionts)

Answers

Answer:

The correct answer is - Biwalves and sponges.

Explanation:

Suspension feeders are the organisms that depend on, for the dietary needs or nutriton, materials suspended in the water. The materials that are suspended are living organisms such as phytoplankton and zooplankton.

Biwalves and sponges are suspended or filter feeders and not predators like other organisms so providing copepods will not complete their food requirement and they will starve to death.

Earth's population over the centuries has risen at an increasing rate. So, the correct option is C.

How the population of Earth is increasing?

This sharp increase in population has been primarily caused by an increase in the proportion of individuals reaching breeding age, the gradual extension of human life expectancy, growing urbanization, and quickening migration. This expansion has been accompanied by significant changes in the fertility rate.

One of the key reasons for India's population expansion is a drop in death rates brought on by better medical services and a steady birth rate. The widespread illiteracy in India makes people believe that "children are god's blessings," which makes them opposed to the idea of "family planning."

Adults: The average adult weighing 150 to 180 pounds should have about 1.2 to 1.5 gallons of blood in their body. This is about 4,500 to 5,700 mL.

For the numbered steps below, select the option that places them in the correct order. 1) The ribosome binds to the mRNA and uses tRNAs to translate mRNA into the corresponding amino acid polypeptide sequence. 2) The spliceosome removes introns. 3) The primary structure of the polypeptide chain undergoes hierarchical foldings to form the tertiary structure. 4) RNA polymerase binds to the promoter region of a gene and initiates transcription.

Answers

Answer:

first 4, then 2, then 1, and lastly 3

Explanation:

First, RNA polymerase binds to the promoter region of a gene on the DNA and initiates transcription. Transcription is the process by which we get mRNA (coding RNA) which is used as a template for protein synthesis. Then, in transcription, the resulting mRNA undergoes modification and maturation. This  involves removal of introns, addition of 3'-poly-A tail and 5'-cap. Introns are sequences that do not code for protein and are hence removed. The structure that removes introns is the spliceosome. Thirdly, mature mRNA travels to the cytoplasm. Ribosome (composed of rRNA) binds to mRNA and tRNA to start the process of protein synthesis. The process of formation of protein is called translation. Lastly, the primary structure of protein may undergo folding to form a tertiary structure.

process called photosynthesis. Oxygen gas is also produced during photosynthesis.
Photosynthesis can only happen in the presence of light. To measure the rate of

sodium bicarbonate solution. Oxygen gas produced by photosynthesis will collect at the
top of the test tube.

During an experiment, the controlled variables are kept constant in the control groups and the experimental groups. Unlike the independent variable, the controlled variables do not influence the results. These variables do not affect the response of the dependent variable.  

In this experiment,

The independent variable → presence/absence of light reaching the plant. The researcher regulates the amount of light by using different elements such as the bucket, lamp, flashlight, and natural light. The dependent variable → oxygen production through which the researcher measures the photosynthesis rate. The controlled variableSodium  bicarbonate  solution. It provides carbon dioxyde, and must be constant in the four scenarios to avoid an effect on the results.

Answers

Answer:

The correct answer is ''arises from the greater splanchnic nerve''

Explanation:

The greater splanchnic nerve or great adrenal nerve, originates in the thoracic sympathetic chain from vertebral levels T5 to T9 (T10). It runs over the bodies of the thoracic vertebrae and as it descends it becomes more anterior. It enters the abdomen crossing the diaphragmatic pillar and ends at the celiac plexus. The upper part of each celiac ganglion continues with the greater splanchnic nerve. The collateral or prevertebral ganglia innervate the abdominal and pelvic organs and viscera. The celiac ganglion receives preganglionic fibers from T5 to T12 and innervates the stomach, liver, pancreas, gallbladder, small intestine, spleen, and kidneys.
