<span>Copying information in DNA is efficient because although the information must be copied individually, every single DNA strand still carries the necessary information that can be used in order to copy over during the replication phase.</span>
weight=mass*gravitational accelaration
we know the weight and the gravitational acceleration
400N=m*10m/s^2
m=400N/10m/2^2
m=40kg

Chlorine is a chemical element with symbol Cl and atomic number 17 that is widely used in the chemical and pharmaceutical industry. It is a t<span>oxic, corrosive, greenish yellow gas, irritating to the eyes and skin.</span>
It is denoted as Cl.
The following statement is NOT true about chlorine: A. It is not reactive.
Answer:
B
Explanation:
A zygote is the resulting cell from fertilization.
Fertilization occurs when the sperm (the male gamete/sex cell) fuses with the egg (the female gamete/sex cell). After they fuse, or fertilize, a cell forms that contains half of the DNA from the father (sperm) and the other half from the mother (egg). It has a complete set of DNA, and is considered a haploid cell.
It is not the structure that nourishes the fetus, an un-fertilized egg, or a ball of about 100 cells. Therefore, the correct answer is <u>B: a sperm fused with an egg.</u>
