The composition of a star is abundant in hydrogen and helium, both of which are two of the lightest elements. Because they are very light, they are usually unstable. To becomes stable, hydrogen atoms spontaneously combine with each other through a radiation process called nuclear fusion, to yield helium atoms. This process requires very high energy in the form of heat. Therefore, these lighter elements are burned in order to keep the star alive with energy.

Therefore, the answer is D.

Pepsin is an enzyme found in the human stomach that breaks down protein. Pepsin will not break down starch.
Andre45 [30]

The statement which best explains why Pepsin will not break down starch is that enzymes only work for specific substrates.

<h3>What is an Enzyme?</h3>

This is referred to as a biological catalyst which helps to speed the rate of chemical reaction in the body by lowering the activation energy needed to start it up. it is also proteinous and can be denatured by heat and other substance such as chemicals.

They are also substrate specific which means they can't act on any type of substance. For example enzyme such as amylase acts on only starch while pepsin acts on only protein.

AlekseyPX

The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".

Mrac [35]

Answer;

The mismatched pair is;

C) receptor proteins — bind with enzymes

Explanation;

- A receptor protein is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some form of cellular/tissue response, e.g. a change in the electrical activity of a cell.

-They are generally trans-membrane proteins, which bind to signaling molecules outside the cell and subsequently transmit the signal through a sequence of molecular switches to internal signaling pathways. There are two types of receptors: internal receptors and cell-surface receptors.
