Answer:
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
Answer:
The positive charge of the histone proteins get reduced due to the process of histone acetylation, thus making the wrapping of DNA around the histones less tightened. The loose connected DNA afterward associates with the transcription factors for the articulation of the genes situated in that area.
Generally, when there is no requirement of gene anymore, the acetyl groups from the histones get withdrawn by the activity of histone deacetylase enzyme (HDAC9) that makes the DNA tightly wrapped and inaccessible again. In case, when less expression of histone deacetylase enzyme occurs, the process of deacetylation fails to take place. This indicates that within an immune cell, at the time of infection, the inflammatory gene, which was made available does not get re-wrapped firmly around the histones.
I'm not completely sure but I think the answer is the last one. The living things need water because it is a major component of a cell membranes answer.
The proteins are biomolecules which can act as hormones and enzyme catalysts which can help in catalyzing the chemical reactions. They help in the transport of the molecules and cell membrane trafficking. The proteins are antibodies which can bind to antigens and the foreign materials. The genetic information is carried by the genes in the DNA, and not proteins.
Thus, the correct answer is option 'They contain genetic information.
Answer:
approximately 4.5
