In the male reproductive system, the pituitary hormone _____ stimulates Leydig cells to secrete testosterone, and the pituitary

Katena32 [7]

Answer:

<u>Luteinizing hormone </u>(LH) stimulates Leydig cells to secrete testosterone

<u>Follicle stimulating hormone (FSH)</u> stimulates Sertoli cells to secrete protein and other molecules required for spermatogenesis

Explanation:

Under the influence of gonadotropin-releasing hormone, the anterior pituitary releases luteinizing hormone (LH) and follicle-stimulating hormone (FSH). In males, LH stimulates interstitial cells of testes (Leydig cell) to secrete the hormone testosterone. FSH acts indirectly to stimulate spermatogenesis by causing the release of androgen-binding protein (ABP) from the Sertoli cells. The function of ABP is to maintain the higher concentrations of testosterone to stimulate the final steps of spermatogenesis in the seminiferous tubules.

Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning with by constructing a mathemat

scoray [572]

Answer:

Since the gene mutates at a rate of 0.76 base pairs every 17.1 million years, to find out the time it would take for 1 base pair to mutate can be calculated by dividing 17.1 million years by 0.76

17,100,000 ÷ 0.76 = 22.5 million years

The following equation can be used to describe this:

μ = [(r2/N2) − (r1/N1)] × ln (N2/N1) = (f1 − f2) × ln (N2/N1)

r1 = the observed number of mutants at time point 1

r2 = the observed number of mutants at the next time point

N1 and N2 are the numbers of cells at time points 1 and 2

Hope that answers the question, have a great day!

Rutherford tracked the motion of tiny, positively charged particles shot through a thin sheet of gold foil. Some particles trave

Marrrta [24]

Answer:

Some particles traveled through empty parts of the atom and some particles were deflected by small areas of high-density positive charge in atoms.

Explanation:

Rutherford concluded from his experiment that there are empty spaces present in most parts of the atom while a heavy positive charge is present in the nucleus of an atom due to which the tiny positively charged particles deflects because of positive-positive charge repulsion. Most of positively charged particles passes undeflected which indicated the presence of empty spaces in the atoms. The electrons revolve around the nucleus have no effect on the deflection of positively charged particles.

The paintings in the museum are to be filed, by genre, then title, In alphabetical order. Which painting would be positioned fou

Dmitrij [34]

Hello. This question is incomplete. The full question is:

The paintings in the museum are to be filed, by genre, then title, In alphabetical order. Which painting would be positioned fourth?

Painting 1 - Title: Morphism, Genre: Abstract, Price: € 10,000.

Painting 2 - Title: Desecrate, Genre: Classical, Price: € 7,000.

Painting 3 - Title: Remix, Genre: Abstract, Prince: € 6,000.

Painting 4 - Title: Instant, Genre: Modern, Prince: € 4,500.

Painting 5 - Title: Fugue, Genre: Classical, Prince: € 17,500.

A. PAINTING I C. PAINTING III B. PAINTING IV D. PAINTING V

Answer:

D. PAINTING V

Explanation:

To find the answer to this question, it is necessary to order the paintings as the question indicates. For this reason, we must first organize the names of the painting genres in alphabetical order. This organization will form the order: Abstract, Classic and Modern.

With that, we can organize the name of the titles, also in alphabetical order, but respecting the order already established in the genres. So we will have the order: Morphism, Remix, Desecrate, Fugue and Instant.

As you can see, the fourth painting in that order is "Fugue" which is the fifth painting.

Explain how corn can be used as an example of Mendel's law of independent assortment.

MatroZZZ [7]

Answer:

Mendel's law of independent assortment states that the genes are separated and inherited independently of each other into the gametes.

The corn can be used to study the law if independent assortment as each kernel of the corn is its fruit. Thus, it is a result of sexual reproduction.

Single corn may contain 800-1000 kernels which may have different shape, texture, structure et cetera as result of independent assortment, that is, each kernel receives alleles of genes independent of each other.

For example, a gene responsible for the texture of kernel would be inherited independently of the gene responsible for the color of the kernel.
