Step 1

Process during which the sperm cells above are formed

96%

114 rated

Answer

Spermatogenesis refers to the process by which male gametes (sperm cells) are produced in the testes through a series of cell divisions and differentiation.

Step 2

Identification of the sperm cell that can constituting good quality semen

99%

104 rated

Answer

Sperm cell A is identified as the one constituting good quality semen due to its complete structure.

Step 3

Instrument to evaluate sperm cells

96%

101 rated

Answer

A microscope is used to evaluate the morphology and motility of sperm cells, allowing assessment of sperm quality.

Step 4

Explanation of how sperm cell in B and C affect the ability of the bull to fertilize

98%

120 rated

Answer

Sperm cell B is unable to fertilize an egg because it lacks an acrosome, which is crucial for penetrating the egg. Sperm cell C cannot move towards the egg due to the absence of a tail, thus hindering the fertilization process.
