Biology
1 answer:
Fudgin [204]3 years ago
5 0
I think the best answer is letter b. which is all of these. By studying fossils, a scientist can determine what organism is found. The scientist also can determine the age of the fossil but it can be recognized as a fossil if it was older than 5,000 years. And lastly, fossils can illustrate the changes of environment, climate and evolutionary patterns of our world.

Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of what
Ira Lisetskai [31]

Answer:

This question lacks options, options are:

A) ADH

B) aldosterone

C) atrial natriuretic hormone

D) oxytocin

E) prolactin

The correct answer is B.

Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of <u>aldosterone</u>.

Explanation:

The female sex hormones produced by the ovary (estrogens and progesterone) are substances that, through the blood, will carry messages to all the organs of the female genital system (uterus, tubes and ovaries) to achieve their correct function. Aldosterone concentration normally increases at the time of ovulation and remains elevated during the luteal phase of the menstrual cycle. Women present during the premenstrual phase, compared to the luteal and follicular phases, an increase in body weight, due to an increase in fluid retention, this because the menstrual cycle modulates the renin-angiotensin-aldosterone system. High levels of estrogen and progesterone in the mid-luteal phase are associated with a greater increase in adrenal and renal hormones and retention of more volume.

Oxygen has a partial negative charge, whereas hydrogen had a partial positive charge.

This means that water molecules are polar and can be used to dissolve a lot of chemicals, that's why water is such a popular solvent.

Mrrafil [7]
A frog gets rid of it's urine through the kidneys because the heart pumps blood throughout the body, the lungs are used to take in O2 molecules and gills are use to filter out the hydrogen in HO2 so they can breathe under water. However the kidneys are part of the waste disposal system (what makes us need trip to the bathroom ever now and then) therefore that is the answer.<span />
