________ thousands of tiny projections that add even more surface area to villi​

Biology
1 answer:
victus00 [196]2 years ago
6 0

Answer:

Each villus, in turn, has thousands of even smaller projections called microvilli (singular: microvillus).

Explanation:

The villi contain capillaries, which are tiny blood vessels. Nutrients are absorbed into these capillaries across the surfaces of the villi and microvilli. Because there are millions of these tiny projections, they greatly increase the surface area for absorption.

postnew [5]

Answer:

There should be 10% thymine

Explanation:

DNA bases come in specific pairs. Guanine pairs up with cytosine and adenine pairs up with Thymine.

According to the problem the DNA sample was 40% cytosine and 40% guanine, so this is correct, there are equal amounts of cytosine and guanine. Now Thymine needs to have equal amounts as adenine, but adenine only has 10%.

If we match up the amount of adenine to thymine, we would have 15% adenine and 15% thymine, but that would excede 100%. So you need to match the thymine to adenine.

10% adenine + 10 % thymine + 40% cytosine + 40% guanine = 100%

When an ionic compound such as sodium chloride (NaCl) is placed in water, the component atoms of the NaCl crystal dissociate int
PtichkaEL [24]

Answer:

The correct answer is C) 1 L of 1.0 M NaCl

Explanation:

NaCl is a ionic compound so it dissociates in water into Na⁺ and Cl⁻ ions. Glucose is a covalent solute so it does not dissociates into ions. So, when we dissolve NaCl we have twice the amount of particles in solution in comparison with glucose. According to this:

A) and B) are solutions with the same concentration (0.5 M) but NaCl solution will have more solute particles than glucose.

C) and D) are solutions with more solute amount because they are more concentrated (1 M), but NaCl solution will have more solute particles than glucose solution ( 1 mol of Na⁺ ions + 1 mol of Cl⁻ ions).

The solution with the greatest solute particle number is C).

PLEASE HELP I only have tomorrow morning to get my grade up.
Anika [276]

oo, The Big Bang theory predicts how much of each element should have been made in the early universe, and what we see in very distant galaxies and old stars is just right. You cannot look in new stars, like the Sun, for this evidence, because they contain elements that were created in previous generations of stars.

i hope you will get some knowledge from here❣
