Answer:
Mitosis is a mechanism in which a single cell separates into two separate cells of daughters. One cell in mitosis? Once splits two similar cells into two. Mitosis is primarily aimed at growth and replacement of depleted cells
Explanation:
Answer:
B) cells or tissue that produce light
Explanation:
It wouldn't be A because photophores do not affect the color of other organisms.
It wouldn't be C because the cells produce light, they don't necessarily change color.
Lastly, it wouldn't be D because it isn't a whole organism producing the light, it's an organ. Organs are multiple tissues working together, and tissues are groups of cells.
A group of similar cells organized to perform a particular function is a "tissue."
Answer:
The <u>pituitary</u> gland controls water balance, growth and blood pressure.
Explanation:
The pituitary gland is also called hypophysis, and is a small gland located in the skull that is responsible for secreting hormones and coordinating the activity of other glands.
Hypophysis is usually divided into two portions, adenohypophysis or anterior lobe and neurohypophysis in posterior lobe. Among other functions, the pituitary gland is in charge of
- Water balance and blood pressure, through the antidiuretic hormone or ADH secreted by the neuro-pituitary.
- Growth, through the secretion of growth hormone or GH, secreted by the somatotropic cells of the adenohypophysis.
This gland is also responsible for the secretion of oxytocin and other hormones in charge of regulating endocrine glandular activity.
Regarding the other options:
- <u><em>Thymus</em></u><em> is a gland present in children and related to immune function.
</em>
- <u><em>Thyroid</em></u><em> is responsible for secreting hormones that control basal metabolism.
</em>
- <u><em>Pancreas</em></u><em> has exocrine and endocrine function, producing digestive enzymes and insulin and glucagon, respectively.
</em>
International means it's involved with more than one nation, so it can't be A or B.
