<span>The primordial germ cell in the embryo undergoes mitosis to produce a spermatogonial stem cell.

The spermatogonial stem cell undergoes mitosis. The new cells could either be stem cells or spermatogonium cells.

The spermatogonium undergoes mitosis to generate a primary spermatocyte.

*** Up until this point, all cells are diploid ****

The primary spermatocyte (diploid) undergoes MEIOSIS I to generate TWO haploid secondary spermatocytes.

Each secondary spermatocyte undergoes MEIOSIS II to generate a total of FOUR early spermatid.

The spermatid mature in the seminiferous tubule, and once they are completely mature they are released into the lumen.

Now called sperm cells, they pass into the epididymis, where they are stored until time to be released during ejaculation

e-lub [12.9K]

Answer:

The statement that accurately compares and contrasts the red blood cell and the white blood cell is that both have the same copy of DNA, but different genes are expressed in the two cell types.

Explanation:

Red blood cells (RBC) and white blood cells (WBC) are two highly differentiated types of cells that come from the hematopoietic system and have different functions in the blood.

Compared to WBC , RBC cells lack a nucleus and have fewer organelles, and their function is to transport gases in the blood, unlike the former which are involved in the body's defence.

<em>Cell differentiation is based on gene expression of the genome, resulting in different types of proteins synthesized in each cell, which give them a different structure and function. </em>

Both <u>WBC and RBC have the same genome</u>, but different genes are expressed in each, giving them different morphological and functional characteristics.

Answer:

C. CALVIN CYCLE(LIGHT INDEPENDENT REACTIONS OF PHOTOSYNTHESIS.

Explanation:

Photosynthesis is the process whereby green plants manufacture their food (organic matters in form of glucose) from carbon IV oxide and water molecules in the presence of sunlight.

The glucose formed undergoes two purposes; provision of energy and in the fixing of carbon.

This process involved two steps : The light dependent process and the light independent (Calvin cycle).

The light dependent reaction takes place in the thylakoid membrane and requires supply of light energy.

ATP and NADPH are formed, water molecules are also formed.

The light independent reaction occurs in the stoma and does not require light energy. The process used the ATP and NADPH formed from the light dependent reaction to fix carbon and produce three carbon sugars.

So the Calvin cycle light independent reaction is involved in the fixing of carbon molecules into organic molecules in the absence of sunlight and the ATP and NADPH formed from the light dependent process of photosynthesis.

natima [27]

Answer: This told him that the allele for a green pod is dominant to the allele for yellow pods.

Explanation: Dominant traits will express themselves even if the allele for the other trait is there. If all of the offspring were green even though they carried the allele for a yellow pod, green must be dominant.

Answer: 2. endospores

An endospore is a structure that remains in the dormant state in some bacteria. The term endospore refers to the seed like form, but actually it is not a true spore. Endospore allows bacteria to restrain it's biological activities like obtaining food and reproduction under harsh environmental conditions like freezing and drying. Under favorable conditions these endospores reactivates. The endospore consist of bacterial DNA and ribosome.
