Answer:
Explanation:
Active cellular transport:
- It is the movement of molecules against the concentration gradient (from low concentration to high).
- Active transport requires expense of energy supplied by ATP.
- It is a rapid way to transport of large sized molecules.
Passive cellular transport:
- It is the movement of molecules along the concentration gradient (from high concentration to low).
- Passive transport does not require expense of energy.
- It is a slow process and small sized molecules get transprorted.
TRUE.

A </span>ribozyme<span> is a ribonucleic acid (RNA) enzyme that catalyzes a chemical reaction. The </span>ribozyme<span> catalyses specific reactions in a similar way to that of protein enzymes. Also called catalytic RNA, </span>ribozymes<span> are found in the ribosome where they join amino acids together to form protein chains.

Greenhouse gases such as carbon dioxide trap heat, helping warm the globe. The surge in carbon dioxide levels due to human activity since the Industrial Revolution is now causing an overall warming of the planet that is having impacts around the globe. And the burning of fuel generates not only carbon dioxide, but also air pollutants that are harmful to human health.
Answer:
<em>A: Multiple genes contribute to human height</em>
Explanation:
What Mendel observed in pea plants is generally considered to be exceptions to what is obtainable in most living organisms. Instead of segregating and assorting independently, a lot phenotypic expressions are as a result of interaction of several genes on different loci (polygenic inheritance) while in some cases, multiple phenotypic expressions are controlled by a single gene.
Human height is a continuously varying character and has been studied to be controlled by multiple genes. In addition, the human height is often a result of complex interaction between genetics and the environment.
The correct answer is A.
To reduce the risks of cross contamination when performing cpr, we should try, as far as possible, and if conditions permit, practice cpr in a clean environment of any chemical or physical waste, that the person who is performing the procedure doesn´t have any respiratory disease that can make the situation worse, having clean hands not to contaminate the patient, keep other people away so fresh air can flow freely.
