5 0

Answer:

1. True

2. True

3. I am not sure what you mean?....

Explanation:

1. A measurement is a quantitative observation that consists of two parts: a number and a unit.

2. At this time, only three countries—Burma, Liberia, and the US—have not adopted the International System of Units (SI, or metric system) as their official system of weights and measures.

A research team needs an antibody that binds to a protein of interest so that protein expression can be monitored. They use epit
antiseptic1488 [7]

Answer:

C.The added epitope disrupts the function of the tagged protein

Explanation:

When an additional sequence is tagged to a protein to use comercial antibodies, there are several reasons why this procedure wouldn't work as expected (note that we're assuming the protein is being expressed but it's not possible to detect it).

For example, the sequence of nucleotide added to codify for the tagged epitope are removed during the RNA processing. In that case, the protein would be expressed without the epitope, so it would be impossible to localize it with the antibodies.

Also, it could be that the new epitope is affecting some way the protein folding, making it not functional. This way, it would be degraded by the cell so it wouldn't be detected.

Another possibility is that the epitope doesn't affects the protein folding nor its function, but during the folding ends up in a conformation that makes it inaccesible for the antibody.

In summary, the way as the possible answers to this question are shown, the correct option seems to be C:<em> The added epitope disrupts the function of the target protein.</em>

Describe two factors that are responsible for regulating the cell cycle. What is their role in the regulation process?
finlep [7]

Answer:

The cell cycle is controlled by many cell cycle control factors, namely cyclins, cyclin-dependent kinases (Cdks) and cyclin-dependent kinase inhibitors (CKIs). Cyclins and Cdks, which are positive regulators of the cell cycle, activate cell cycle factors that are essential for the start of the next cell cycle phase.

Explanation:

Listen to pronunciation. (sel-SY-kul REH-gyoo-LAY-shun) Any process that controls the series of events by which a cell goes through the cell cycle. During the cell cycle, a cell makes a copy of its DNA and other contents, and divides in two.

How does the movement of particles of matter change when temperature increases?
saveliy_v [14]

Answer:

Increases

Explanation:

The movement of particles of the matter increases with the increase in temperature.

The particles gain kinetic energy with increasing temperature and move in faster rate.

<u>For example:</u> When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.

Hence, the correct answer is "increases".

Which two body systems interact to expel the waste product carbon dioxide
Pani-rosa [81]

Answer:

excretory system  and circulatory system

Explanation:

Blood is  part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the  blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
