Idk if im in the right subject but please help

A.

Let's break it down:

-If the study has been conducted by multiple others and they get different results, it might be a sign that something went wrong in the experiment, and the data is unreliable. For example, if everybody else timed an event and got the same exact time except for the fact that you got a different time, you may start to suspect that you had done something wrong and the data was unusable.

What happens to the density of the Earth’s Layers as you move towards the core of the earth

zhenek [66]

Answer:

Core is the densest layer of the earth.

Explanation:

The structure of the earth's interior is made up of several concentric layers. The earth's interior is divided into three layers- The Crust, the mantle and the core. The density of the outermost layer the crust is 3 g/cm^3. As we move towards the interior, the earth become more dense. The density of the second layer mantle ranges between 2.9-3.3 g/cm^3. The core is the innermost layer of the earth, surrounding the earth's center. the density of the core ranges between 9.5-14.5 g/cm^3.

Tyra created a chart that compared DNA and RNA for her science class.

KATRIN_1 [288]

Answer:

Okay, 3 of the answer choices on this are wrong. The only correct answer is "DNA remains in the nucleus while RNA leaves the nucleus."

Explanation:

1. DNA is single-stranded while RNA is double-stranded

- INCORRECT. This is the opposite. RNA is single-stranded, whereas DNA is double-stranded.

2. DNA remains in the nucleus while RNA leaves the nucleus.

- This is true because the RNA must leave the nucleus to undergo translation into a ribosome in the cytoplasm.

3. DNA contains a ribose sugar while RNA contains a deoxyribose sugar.

- INCORRECT. This is the opposite. DNA contains deoxyribose sugar, whereas RNA contains ribose sugar.

4. DNA has bases of A, G, C, and U while RNA has bases of A, G, C, and T.

- INCORRECT. This is the opposite. DNA have bases of A, G, C, T, whereas RNA has bases of A, G, C, U. RNA sequences never have the bases of Thymine (T) as the same goes with DNA sequence that does not have the base of Uracil (U).

Honestly, I don't if the question are selectable choices or only one choice answers. There are three wrong answers and one correct answer.
