The question is incomplete as it does not have the options which are:

a. mosses.

b. charophytes.

c. ferns.

d. gymnosperms.

e. flowering plants.

Answer:

C. ferns.

Explanation:

In the given question, the characteristics of a newly identified species were provided which are:

1.  Flagellated sperm: shows that it is either a bryophyte or pteridophyte

2. Dominant sporophyte: chances that it is a pteridophyte

3.The xylem and tracheids: shows that vascular bundle is present which confirms that it is pteridophyte

4. No seeds: confirms that the plant is pteridophyte as vascular bundles with no seed are pteridophyte.

Therefore in the given question, the identified plant is a pteridophyte which in the given option is a fern.

Thus, Option-C is correct.

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.

An air mass forms over the North Pole region describe what you think the temperature and humidity of this air mass will be like?
soldi70 [24.7K]

Answer: hope this helps :)

The motion of air mass motion is usually based upon the air flow in the upper atmosphere. As the jet stream changes intensity and position, it affects the motion and strength of air masses. Where air masses converge, they form boundaries called "fronts".

3-D view of a cold front.

Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.

The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses. Therefore, as these cold air masses move, the dense air undercuts the warmer air masses forcing the warm air up and over the colder air causing it to rise into the atmosphere.

So, fronts just don't appear at the surface of the earth, they have a vertical structure or slope to them as well. Warm fronts typically have a gentle slope so the air rising along
