Atria is a large part of the heart so too big for cells; arteries & veins lead away or to the heart.
Capillaries are the smallest vascular structures that allow materials to be exchanged easily between cells.

Answer:

Capillaries

Explanation:

Capillaries are the smallest blood vessels in the human body. They connect arterioles (smallest arteries) to the venioles (smallest veins). They are made of inner endothelial layer and outer epithelial layer, thus they are only two layers thick. They play important role in circulation. The capillaries transport gasses, fluids, and nutrients in the body tissues and also facilitates exchange of gases (oxygen and carbon dioxide), diffusion of fluids and nutrients into the body tissues and transport of waste materials.

Translate the word phrase into an algebraic equation: the quotient of 24 and 2 is equal to 12.
igor_vitrenko [27]

Answer:

24/2 = 12

Explanation:

(I'm pretty sure this isn't a Biology question, but I'll answer this because I'm nice.)

To translate English into algebriac equations, we have to understand what the symbols in algebra mean. Here are some we should know:

= : "equal to", "is", "equivalent to", etc.

> : "greater than"

< : "less than"

>= : "greater than or equal to", "at least"

<= : "less than or equal to", "at most"

We also have to know basic math operations:

a + b : "a added to b", "a plus b", "a combined with b", "a more than b", etc.

a - b : "a minus b", "b less than a", "b subtracted from a", etc.

a * b : "a multiplied by b", "a times b", "the product of a and b", etc.

a / b : "the quotient of a and b", "a divided by b", etc.

There are MUCH MORE examples of this, yet it becomes second-nature to change English sentences into algebra.

So, let's tackle the question. Sadly, it's pretty simple, so I won't really go in depth here. Since the quotient of a and b is a/b, the quotient of 24 and 2 is 24/2. We can also say that "is equal to 12" is "= 12". So,

24/2 = 12.

How do scorpio reproduce
krok68 [10]

Unlike most nonmammalian animals, scorpions are viviparous, giving birth to live young instead of laying eggs. Once fertilized, the eggs are retained in the female's body, where the embryos are nourished in utero for periods varying from several months to a year.
