Answer:

Explanation:

One of the assumptions of the Hardy Weinberg equilibrium is that the population should not experience mutations. Mutations are usually the base on which natural selection acts by selecting the advantageous alleles and weeding out the disadvantageous ones. This is how populations evolve.

Other assumptions of this equilibrium are; there should be no migration (hence gene flow), the population is infinitely large, and mating is random.

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown answer

larisa86 [58]

Three lots with parallel side boundaries extend from the avenue to the boulevard as shown in the diagram attached.

Given;
x + y + z = 140 meters

According to the proportion theorem,

$\frac{x}{40} = \frac{y}{30}$

Solving for x, using cross multiplication:

$\frac{x}{1} = \frac{40y}{30}$

Similarly,

x/40 = z/35

solving for z by cross multiplication,

z = 35x/40
z = 7x/8

Now, the third proportions,
y/30 = z/35

Solving for y,

y = 30z/35
y = 6z/7

x + y + z = 140

4y/3 + 6z/7 + 7x/8 = 140

(224y + 144z + 147x)/168 = 140

224y + 144z + 147x = 23520

Substitutoing z = 7x/8,

224y + (144 × 7x/8) + 147x = 23520

224y + 126x + 147x = 23520

224y + 273x = 23520
Now,
Substitute y = 3x/4

(224×3x/4) + 273x = 23520

168x + 273x = 23520

441x = 23520

x = 53.33

Now,
We know that
y = 3x/4
so,
y = 40

And,
z = 7x/8
Z = 46.66

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.

True or false? pain should be the limiting factor in all rehabilitative exercises.

Lilit [14]

False. Sometimes pushing yourself can help your mind to tell itself "I can do this!" Besides, sometimes pain is a great motivator!
