Answer:
orensically valuable DNA can be found on evidence that is decades old. However, several factors can affect the DNA left at a crime scene, including environmental factors (e.g., heat, sunlight, moisture, bacteria, and mold). Therefore, not all DNA evidence will result in a usable DNA profile.

Question 4 I need help with
If each parent has two sets of genes and chromosomes why do their offspring receive only one set from each parent
Answer:
Because we are diploid humans, and we have 2 chromosomes per set. We get one set from our mother, and one from out father. Each of the sets from our parents are haploid (1 ), so together they are a diploid(2) set. I can go into depth more with meiosis if you need.
Explanation:
-. What describes the conversion of ADP to ATP?
Answer:
Two processes convert ADP into ATP: 1) substrate-level phosphorylation; and 2) chemiosmosis. Substrate-level phosphorylation occurs in the cytoplasm when an enzyme attaches a third phosphate to the ADP (both ADP and the phosphates are the substrates on which the enzyme acts).

some scientists predict that if global warming continues over the next few centuries, melting of the polar ice caps will rise the level of the oceans causing some peninsulas to become islands. how might this change eventually affect the species that live on these peninsulas?
Answer:
As global warming causes more snow and ice to melt each summer, the ocean and land that were underneath the ice are exposed at the Earth's surface. Because they are darker in color, the ocean and land absorb more incoming solar radiation, and then release the heat to the atmosphere.

Answer:
a genetic mutation passed on by one or two of their parents.
Explanation:
what is Nuclear Fusion.
Answer: Nuclear Fusion occurs when the nuclear components of an atom combine.
Which explains why the nuclear membrane breaks down during cell division?
So the cytoplasm can be divided.
So the duplicated chromosomes can be separated into new cells.
So the chromosomes can be replicated.
So it makes it easier for the DNA to be mutated.
