Answer:
This question is all explanation, buddy. Take a read.
Explanation:
To start, you need to have a basic understanding in what chromosomes are. There are 23 pairs of chromosomes (46 total) in each cell. Almost all the other cells in your body have 46 chromosomes. There are two types of cells that are different, however. These are the eggs in a female and the sperm in a male. These sex cells , or gametes, have 23 each.
The sperm passes through the opening of the cervix and travels into the fallopian tubes. There, the sperm will penetrate and fertilize an egg. You'd like to think this is a one on one process, but actially- many sperm cells attempt to try to penetrate the egg but only one makes it in. no more than one, though. Once fertilized, the egg travels down the fallopian tube toward the womb, or uterus, where it will implant in the uterine wall.
During early pregnancy, a female's egg joins with the father's sperm to make a new cell. The cell then will grow and divide into a baby. This first cell has 46 chromosomes, 23 from the mother and 23 from the father. The genes on these chromosomes contain all the instructions for how the child will grow. Each cell of the body will contain exact copies of the 23 pairs of chromosomes that were in the first cell that was formed by the egg and sperm. The determination of which genes the child gets though (aside from essential genetic material) is up to the genetic lottery, however the likelihood of certain genetic traits can be mapped and predicted. Like hair colour, eye colour, etc. But that's an unrelated (to this question, anyway) subject altogether.
I hope that answers your question.
Answer:
The answer for this question would be option B. The goal of vaccinations is to reduce the number of certain cases of a particular disease. Given that 79% of the children born in the Western Pacific region received a dose of hepatitis B vaccine, and only 11% in one African region, this would mean that the Western Pacific region will have fewer cases of hepatitis B than the African region.
Explanation:
If the answers are:
A.
The Western Pacific region will have more cases of hepatitis B than the African region.
B.
The Western Pacific region will have fewer cases of hepatitis B than the African region.
C.
The Western Pacific and African regions will have same number of cases of hepatitis B.
D.
Nearly 90% of people will be immune to hepatitis B in both regions.

Answer:
I don't know the exact word they want, but organisms use energy for motion and any activity they perform regularly. (eg: hunting, climbing, digging, etc.)
Answer:
Mitochondria
Explanation:
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).
Dissecting microscope is a kind of microscope that is limited to view an opaque object. Dissecting microscope is also called as the stereo microscope. This microscope can magnified up to 300 times. Dissecting microscope can be used in electronic industry also.
