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.

Aloiza [94]

Answer:

The correct answer will be option-D

Explanation:

Arid areas are the regions of the world which can be marked with the lack of water conditions, high light intensity and very low rainfall.

Water is one of the primary requirement of the plant without which no plant can survive but the adaptability to the environment allows the existence of the life on earth. There are known species of plants which are adaptive to such arid conditions.

If a farmer is interested in growing plants in such arid conditions hen he should select the plants which could better be adapted to survive in the arid conditions either by avoiding arid condition like storing water, low transpiration, extensive root system and many others.

Thus, Option-D is the correct answer.

You are helping your brother build the deck. he accidentally cuts off his thumb. what should you do next?
netineya [11]
The correct answer is "<span>Wrap the thumb in gauze, place in a bag and then on ice". 

Wrapping the cut-off finger in gauze or in any cloth, should be immediately placed in a bag then put on ice for it to be chilled. the thumb should not be exposed directly to the ice, or it will cause ice burns, wherein it will cause the thumb to not get sewn back. the ice is used to chill the thumb, to prevent the it from decomposing, not for freezing it. </span>
