Based on figure 21-1 ,animals are most closely related to

Answers

Answer 1

Answer:

Answer: The correct answer is-

Choanozoa.

A phylogenetic tree is a representation of evolutionary relationship between different species. It is constructed on the basis of their similarities and differences in their morphological ( physical traits) as well as genetic characteristics.

Two species are said to be most closely related if they share most recent common ancestor. In other words, when two species are descended from a most recent common ancestor, they are said to be most closely related with each other.

In this question, Animals and Choanozoa share most recent common ancestor.

Thus, animals are most closely related to Choanozoa.

Answer 2

Answer: Choanozoa—It's the branch that animals are most directly connected to.

If a local anesthetic blocks neural transmission what hormones would be affected and in what direction (up or down) if the anesthetic is applied to the infundibula stalk below the hypothalamus. What would be the short-term acute effects on the body?

Answers

The correct answer for the question that is being presented above is this one: "local anesthetic do not affect hormones. They block sodium channels in sensory, motor and sympathetic neurons and stop transmission along those nerves. They cause numbness, motor paralysis and sympathectomy. They do not affect hormones. Seriously. I'm not kidding. So, NO hormones, and neither up nor down because they are not affected."

Why is there more oxygen and carbon dioxide near the surface of the ocean than near the ocean floor? Organisms near the ocean floor cannot process these gases, so there is more gas at the surface. The salinity of ocean water traps these gases and prevents them from escaping into the atmosphere. Organisms near the surface do not use up these gases, so there is more gas at the surface. The exchange of these gases between water and the atmosphere occurs more readily at the surface.

Answers

There is more oxygen and carbon dioxide in the surface of the ocean because these gases rises and floats thus it will stay near the surface. Also, the solubility of these gases in water is small therefore only small concentrations can be found in water.

Genes are segments of a chromosome that are responsible for specific hereditary traits. Please select the best answer from the choices provided.a. True
b. False

Answers

True. Genes are part of chromosomes and they contain DNA. Inheritance of traits occurs when genes - discrete units that can be inherited - are passed along in reproduction, from parents to offspring. Alleles are variant forms of genes that give rise to differences between people.

Conservation biologists are most interested in which three evolutionary mechanisms?

Answers

The goal of conservation biology is to protect ecosystems and the species contained within, which are vital to the biodiveristy of earth. The evolutionary mechanisms most important to conservation biologist are heredity, variation and natural selection. In essence, these three points summarize Darwin's work, which details the evolutionary process that occurs to species throughout time and the ecological effects of such.

Histamine is a chemical substance released in inflammatory and allergic responses. The histamine H1 receptor on target cells is a G protein-coupled receptor that activates phospholipase C in response to the binding of histamine. Which statements are true about the binding of histamine to the histamine H1 receptor? Select all that apply. Histamine diffuses across the plasma membrane to bind to the H1 receptor. Histamine binds extracellularly to the H1 receptor. When histamine binds to the H1 receptor, the receptor undergoes a conformation change and binds the inactive G protein. Histamine binds intracellularly to the inactive G protein, activating the G protein. Once the G protein is active, it binds to the enzyme phospholipase C, activating it. Histamine is likely hydrophilic.
