4. Cell differentiation occurs.

Answers

Answer 1

Answer: 2. Meristem cells would form.

Explanation:

Permanent cells are cells that are incapable of regeneration. These cells are considered to be terminally differentiated and non-proliferative in postnatal life. This includes neurons, heart cells, skeletal muscle cells and red blood cells.

why not test for pathogens like salmonella directly rather than use an indicator organism such as a coliform?

Answers

Indicator organisms are organisms that are utilized to detect the presence of another organisms that cannot be easily identified.

We do not test for pathogens like salmonella directly but use an indicator organism like coliform because these pathogens are not easily isolated and they are much harder to identify.

Pathogens like salmonella are not tested for directly because they are much lower in numbers when found in wastes or waterbodies and to identify them directly is expensive.

Also testing directly for these micro-organisms is very expensive and non-viable. So it is better to use indicator organisms to detect their presence.

Which researcher theorized that hypnosis comes about as a form of roleplay between hypnotist and subject? A. Ernest Hilgard B. Theodore Sarbin C. Theodore Barber D. Milton Erickson Please select the best answer from the choices provided A B C D

Answers

Answer:

Hey, your answer should be D

Explanation:

Good luck friends

The researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D. Milton Erickson was a famous American psychiatrist and psychotherapist.

What is Milton Erickson?

He is widely known for his pioneering work in the field of hypnosis. He believed that hypnosis is a form of communication between the hypnotist and the subject and that it involves a process of "roleplay" in which both parties take on certain roles or identities. In this sense, the hypnotist takes on the role of a facilitator or guide, helping the subject access their own inner resources and abilities. The subject, on the other hand, takes on the role of an active participant in the hypnotic process, using their own imagination and creativity to bring about positive changes in their thoughts, feelings, and behaviors.

Hence, the researcher who theorized that hypnosis comes about as a form of roleplay between hypnotist and subject is Milton Erickson, who is in Option D.

Answers

The correct order of glycolysis reactions is:

Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four  molecules of ATP are produced.

During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.

The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.

An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.

A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.

A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.

Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.

what determines how closely related 2 species are?

Answers

Answer:

Before: (Darwin did) Physical features and behavior

Now:

DNA Testing

Explanation:

Similarities are often easy to see when one looks at two organisms that evolved from a common ancestor, and until recently, looking at physical features and behavior was the only way to determine how closely related two organisms are. However, now scientists can also analyze DNA to discover how closely organisms are related. Every living creature has DNA, which has a lot of inherited information about how the body builds itself. Scientists can compare the DNA of two organisms; the more similar the DNA, the more closely related the organisms. This method can also help when looks are deceptive. One example of looks being deceptive is: The bat and the crow both have wings, and the squirrel does not. From this, one may think that bats and crows are more closely related than bats and squirrels, while the opposite is indeed the case.

The microscopic filtering units found in the kidneys that are responsible for urine formation are called nephrons, so here the correct option is option a.

Throughout the nephron, various processes such as filtration, reabsorption, and secretion occur to produce urine. Filtration occurs at the glomerulus, where water and small solutes are forced out of the blood into the Bowman's capsule. Reabsorption involves the selective reabsorption of water, ions, and nutrients from the filtrate back into the bloodstream. Secretion involves the active transport of waste products, excess ions, and toxins from the bloodstream into the filtrate. So here, the correct option is option a.
