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.
Answer;
The above statement is true;
When fasting continues long beyond glycogen depletion, body protein will be broken down to make glucose,
Explanation;
When the body runs low on fuel, it utilizes the stored glycogen in the liver and muscle, which is the primary source of stored energy. The after the depletion of glycogen the body burns fat, and if fasting continues the body begins to break down non essential proteins for energy. protein is the last source of stored energy available to the body.
The appropriate title of the scatter plot is solubility curve of sugar
The independent variable is temperature
The dependent variable is mass of sugar in grams that can dissolve in 100 mL of water
The solubility curve is a graph of the amount of solute dissolved in a given volume of solvent against temperature.
The solubility of the solute is plotted on the vertical axis while the temperature is plotted on the horizontal axis.
The independent variable is the temperature while the dependent variable is mass of sugar in grams that can dissolve in 100 mL of water.

Answer:
Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity.
Explanation:
the number of trophic levels in a food web
Answer: Only Options A, C and E are correct
A) Sympatric speciation is best described as a random event that disrupts the allele frequencies in a population
C) Sympatric speciation does not require geographic isolation.
E) Sympatric speciation can be due to sexual(mate) selection
Explanation:
Sympatric speciation is a random or naturally occurring event whereby organisms of the same species:
> live in the same territory or nearby territories ( i.e not living in isolation)
> DO NOT interbreed, but select a sexual mate from a much diverse territory which results in an uneven gene flow or disruption of alleles among the population of same species of the parents organisms.
