The correct answer is D. Without capsids, viruses could not replicate

Explanation:

A viral infection is caused as a virus enters the body and this replicates inside it by using the host's cells. This is possible through the capsid which is an external layer in the virus that provides protection to it and helps the virus replicate because the capsid is essential for the virus to attach and penetrate the host's cells to replicate. According to this, if a drug damages the capsids the virus could not replicate and this should or reduce the infection caused by the virus. Thus, a drug that damages capsids helps treat a viral infection because "without capsids, viruses could not replicate".

In the figure below, ΔMNO≅ΔPQR.What is the measure of ∠P? Show your work and explain your reasoning.

Juliette [100K]

Answer:

$\huge\boxed{\sf P = 79.5\°}$

Explanation:

<u>Given that:</u>

ΔMNO ≅ ΔPQR

That means

M ↔ P

N ↔ Q

O ↔ R

So,

∠P ≅ ∠M

Given that P = 3x + 20.4 and M = 5x - 19

3x + 20.4 = 5x - 19

Add 19 to both sides

3x + 20.4 + 19 = 5x

3x + 39.4 = 5x

Subtract 3x to both sides

39.4 = 5x - 3x

39.4 = 2x

2x = 39.4

Divide both sides by 2

x = 19.7

<u>Given that:</u>

P = 3x + 20.4

P = 3(19.7) + 20.4 (x = 19.7)

P = 59.1 + 20.4

P = 79.5°

Answer:

the chemical

Explanation:

A variable whose variation does not depend upon on any other variable in any manner is termed as independent variable.
An independent variable is the one that can only be actually varied by the experimenter who is using it to test the affect of this particular variable on other variables that depend on it and thus, change as the independent variable is changing.
In the given experiment the scientist is testing the effect of spraying chemicals on the apple yard, here<em> the chemical used is an independent variable as varying the amount of chemical that is sprayed will change the yield of the apples. </em>

1. If a strand is given to you, and you have to identify whether it is DNA or RNA how will you identify it?

pickupchik [31]

One big way to tell a difference is that DNA is double stranded, in the shape of a double helix, while RNA is single stranded. (This is why RNA can leave the nucleus and DNA cannot) There are also factors that affect the difference like how DNA contains thymine, and when RNA makes copies of it, it becomes uracil.
