Answer:
enzymes are special proteins that increase the rate of a reaction by decreasing the amount of energy needed to get a reaction started
Explanation:
Genetic variation in offspring during sexual reproduction is caused by
- crossing over
- independent assortment
- randomized fertilization
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.
Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.
- crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
- independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
- randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes

A statement that carbon is matter and cannot be created or destroyed is an example of part of a scientific theory and is denoted as option A.
<h3>What is a Theory?</h3>
This term refers to series of principles which helps to explain a particular phenomenon.
The most suitable choice will therefore be option A as it helps to explain why carbon can't be created or destroyed due to it being a matter and is the correct choice.

The medicare prospective payment system for reimbursing hospitals utilizes APCs.
APC stands for Ambulatory Payment Classifications that includes the outpatient payment system which is applicable only to the hospitals. There are different reimbursement methods for hospitals outpatients, inpatients, physicians, etc.
