Answer:
<h3>Enzymes are typically which type of biomolecule?</h3>
Enzymes are protein biomolecules.
Enzymes are bound to specific substrate/s and act as <u>catalysts</u> that makes chemical reactions faster, such as breaking down lactose to smaller units of glucose, which is accomplished by lactase.
<u>Cofactors (metal ions such as iron, zinc) and coenzymes (organic molecules like vitamins)</u> may be needed to initiate chemical reactions.
<h3>Describe the effects that enzymes can have on substrates.</h3>
After creating the <u>enzyme-substrate complex</u> through <u>induced fit</u>, enzymatic products are seen after the reaction. The <u>substrates may be consumed during the process or preserved</u> to be used again.
For example, these enzymatic products may be used for feedback inhibition to control the chemical reaction and production of a certain hormone.
Answer: Option A.
Explanation:
Feathers are the epidermal growths which form the distinctive outer covering, or plumage of birds and several other vertebrates.
The major function of feather is to provide heat to the body which is possible by two ways light insulation (radiation) and conduction. In light insulation, feather of birds have the property of light scattering that allows to diffuse thermal radiation to keep the body of birds warm, results in heat conservation while in conduction, layer of air is trapped in the furs of feather which slowly heated the bodies of animals or birds.
Hence, the correct option is A.
A hypothesis is a supposition based on data or information that is trying to explain something.
A theory is an explication for something that is scientifically accepted.
Every law is a universally accepted knowledge that is checked by, for example, a math formula.
All scientific knowledge is not permanent, can change if someone demonstrates it's wrong.
A hypothesis is the most important of this, is the start of scientific knowledge.
Answer:
The answer is 2; Lake.
Explanation:
A lake (from Latin lacus) is a large body of water (larger and deeper than a pond) within a body of land. As a lake is separated from the ocean, it is not a sea. Some lakes are very big, and people in the past sometimes called them seas. Lakes do not flow like rivers, but many have rivers flowing into and out of them.
