Most organisms obtain energy from food by the process of cellular respiration. Which is the MOST LIKELY explanation for what pre

vents Earth from running out of oxygen? A. The overall reactions of photosynthesis and cellular respiration are the opposite of one another, therefore the products of one are the reactants of the other, creating a cycle. B. The energy—and thus oxygen—flows for cellular respiration and photosynthesis take place in the same direction, and therefore build upon one another. C. Cellular respiration is a process that deposits energy and oxygen, and photosynthesis withdraws energy and uses oxygen, therefore balancing each other. D. Oxygen readily accepts electrons, so cellular respiration uses a negligible amount of oxygen. E. Cellular respiration is balanced by fermentation, an alternative process of glucose metabolism which returns oxygen to the atmosphere.

Dennis_Churaev [7]

Produced by the anterior pituitary. It's regarded as a tropical hormone. Target cells are impacted by tropical hormones indirectly after being stimulated.

<h3>The anterior pituitary gland affects which organs?</h3>

The following organs, glands, and bodily tissues are affected by and interact with the anterior pituitary hormones: organs, muscles, and bones the growth hormone (GH). Adrenocorticotropic hormone: Adrenal gland (ACTH). thyroid hormone, which stimulates the thyroid gland (TSH).

<h3>What are the anterior pituitary gland's seven hormones?</h3>

Frontal pituitary

hormone adrenocorticotrophic (ACTH)

hormone that stimulates the thyroid (TSH)

Luteinizing agent (LH)

hormone that stimulates ovulation (FSH)

Prolactin (PRL) (PRL)

hormonal growth (GH)

MSH, or melanocytic-stimulating hormone

Because it releases hormones that regulate the thyroid, adrenal glands, ovaries, and testes, the pituitary gland is frequently referred to as the "master gland."

Answer:

Here are the answers:

a. 4  Cell determination as an issue in the *rest is missing*

b. 4  They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.

c. 4  I and III only

Explanation:

The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.

Cleavage Planes:

Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.

Cell Differentiation:

Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
