Answer:
Sequence of nucleotides in the DNA strand
Explanation:
Deoxyribonuceic acid or DNA is a biological material that stores the genetic information of an organism.
DNA encodes the information through the order or sequence of the nuceotides along each strand. Organisms differ from one another because their respective DNA molecule have different nucleotide sequences and consequently, carry different biological instructions.
A DNA strand consists of two polynucleotide chains, composed of four nucleotide subunits. Each of these chains is known as DNA strand. Hydrogen bonds between the base portions of the nucleotides hold the two chains together. DNA nucleotides are composed of a 5-carbon sugar (Deoxyribose) to which are attached one phosphate group and a nitrogenous base (Adenine, Guanine, Cytosine and Thymine). The nucleotides are covalently linked together.
Answer: B. Pathways by which matter is transferred between organisms and the environment
Explanation:
Biogeochemical cycles can be define as cycles which involves the natural pathways by which inorganic and organic matter is transferred within the living organisms and the environment.
The essential elements such as water, carbon, phosphorous, nitrogen and oxygen are transferred among the various spheres of the earth like atmosphere, biosphere, lithosphere and others which forms the integral part of the non-physical environment.
Answer:
small molecules easily pass through the phospholipids in the cell membrane
If you sequence the dna of human as well as chimpanzees almost 99% of the sequence are similar showing they are phylogenetic related
