Answer: Option A

Explanation:

The more hot the star is the more blue it looks. The cooler stars are blue in color and temperature is approximately 11,000 Kelvin and it gives Rigel.

It contains 40,000 times the energy of the Sun. The stars are blue in color because of its surface which appears to be blue.

Whereas, the stars that are colder appears red in color. The colder stars appears to be red in color. So, the star having greater temperature appears blue and cooler star appears.

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.

In three to five sentences, describe the advantages and disadvantages of these maps in modeling mitosis.
zhenek [66]

Answer:

Mitosis involves in cell division.

Explanation:

Mitosis may be defined as a process of cell division which results in the formation of two daughter cells each from a parent cell and each cell having having the same number of chromosomes and chromosomes of the same type as that of the parent nucleus.

The main difference between meiosis and mitosis of a nucleus cell is that it involves only one cell division. And so the cell goes by the steps of prophase, then metaphase, then anaphase and finally telophase. The specialized cells could not survive independently to each other, so they have to develop some complex system of communications like the circulatory system and the nervous system. In this way they can survive. If one of the system dies, entire organisms is more likely to follow.
