which of the following statements about the clonal selection theory of immune system function is false?
-a. antigens are recognized by receptor proteins inside the lymphocyte
-b. an activated lymphocyte makes many copies of itself in response to an infection
-c. cloned cells persist after the pathogen is eliminated
-d. each lymphocyte recognizes one antigen

Answers

Answer 1

The false statement about the clonal selection theory of immune system function is statement A, “antigens are recognized by receptor proteins inside the lymphocyte.” This statement is false because antigens are actually recognized by receptor proteins on the surface of the lymphocyte.

The clonal selection theory of immune system function states that when antigens enter the body, they are recognized by receptor proteins on the surface of the lymphocyte. This triggers the activation of the lymphocyte, which will then make many copies of itself in response to the infection. The cloned cells will persist in the body even after the pathogen has been eliminated. Each lymphocyte has the ability to recognize one antigen.

The clonal selection theory of immune system function is the basis for the human body’s ability to respond and protect itself from disease. It is a complex process that allows the body to recognize, fight, and remove foreign invaders, therefore protecting us from harmful bacteria and viruses.

Answers

Answer:

Axis - B

Rotation - E

Revolution - D

Latitude - A

Gravity - C

Explanation:

The axis is the line that a body spins on. The axis will line up with the north and south poles. For Earth, the axis is tilted, which is why seasons exist.

The definition of rotation is "the action of rotating around an axis or center." So, rotation is the spinning of a body on its axis. On Earth, one rotation is equal to one day.

Revolutions are when a body spins around another. For Earth, one revolution around the sun is one year

Latitudes are invisible lines that separate the world into degrees from North to South. They are also called parallels.

Gravity is the force that keeps things together. Large masses have gravity that attract other masses.

Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids

Answers

Answer:

Proteins

Explanation:

There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.

Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

what makes lipids/fats hydrophobic?

Answers

Answer:

Lipids are hydrophobic because they do not mix with water. Lipids are made of long chains of carbon and hydrogen. ... The partial charges on the water molecule cannot interact with the neutral lipid molecule and thus water and lipids do not mix.

Answer:

"this hydrophobic ("water fearing") nature of lipids is driven by the bonds between these many carbons and hydrogens. ... Thus, long chains of carbon-hydrogens bonds form a nonpolar molecule."

A scientist exploring in the rainforest found an unclassified organism. It is multicellular and made of multiple thread-like structures. The organism has cells with a nucleus and a cell wall made of chitin. The scientist should classify this organism as belonging to the kingdom—

Answers

Answer:

Kingdom Fungi

Explanation:

Based on certain characteristics possessed by living organisms, they have been classified into five different kingdoms namely; plantae, animalia, monera, protista and fungi. Organisms with similar characteristics have been placed under the same kingdom.

Kingdom Fungi is a kingdom that contains organisms that possess characteristics different from plants and animals. Some of these features are those possessed by the unclassified organism found in the rainforest and they are as follows:

- They are eukaryotic (possess a true nucleus) and multicellular (have more than one cell).

- Their cell wall is made of chitin (a carbohydrate)

- They are made of multiple thread-like structures called HYPHAE.

Based on these mentioned characteristics above, the scientist should classify this organism as belonging to the kingdom FUNGI.

O All are tall and purple
O Three-quarters of the plants are short and white
All are short and white
Three-quarters of the plants are tall and purple

Answers

Answer:

A. All are tall and purple

Explanation:

When you set up a punnet square, all of the results would be TtPp.

When a dominant trait is present, it preceeds over the recessive trait. (Also it depends on what genotypes are given. Ex: In flowers if they gave RR shows red, Rw shows pink, and ww shows white, but that's not the case here given that there are only 2 genotypes).

So to break it down:

Tt -> tall plant

Pp -> purple plant

so they are all tall and purple.

When both lactose and glucose are available to E. coli, which part of the lac operon regulation assures that glucose will be metabolized first? Permease allows lactose to enter the cell when lactose enters the cell. The repressor binds to the operator in the absence of lactose. The repressor cannot bind to the operator in the presence of lactose. RNA polymerase transcribes the lac operon to make a single RNA molecule.
