600-400= 200N to the left.
Answer:
Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. Duplication of the genetic information occurs by the use of one DNA strand as a template for formation of a complementary strand.
Explanation:
A characteristics that helps an organism to survive and reproduce is the best description of an adaptation.
Option D
<u>Explanation</u>:
Adaptation is simply defined as the evolutionary process of the organism when they feel comfortable to their natural place of existence. The process takes place in many generation to generation and it is passed on with genetic inheritance. With its biological phenomena it explains a trait in organisms which helps animal to survive and reproduce. It is also process of changing to different places for the organisms. Adaptation happens through mutation or natural selection.

red blood cell
Explanation:
you have more red blood cells than another cell I. your human body
Answer:
Chromosomes are systemized structures of proteins and DNA. It have a string like shape, mainly located within the nucleus of both plant and animal cells. DNA is concentrated in the chromosomes. In 1902, Sutton and Boveri proposed that chromosomes has a part in heredity opposing Mendel's theory of segregation and independent assortment.
One major function of the chromosome is to keep the DNA from being altered or negatively influenced during cell division. It ensures accurate distribution of the DNA during the breaking down of genetic material. In mitosis, the chromosomes are duplicated and dispersed to daughter cells so that each cell attains a diploid set of chromosomes totally of the same nature to that of its parent cell. In meiosis, the resultant cells would attain a chromosome from each chromosome pair this will lead to half the number of chromosomes. This process is important for the offspring being produced to have the same characteristics of the parents which would results from the fusion of the sperm and egg of the parents.
