Answer:
The genetic material of most of the organism is Dexoxy-ribonucleic acid OR DNA which are formed of the monomer unit called nucleotide.
Each nucleotide is composed of a 5-C deoxyribose sugar, a phosphate group and 4 types of nitrogenous bases mainly adenine, cytosine, guanine and thymine.
It is the sequence of these nitrogenous bases which determine the fate of a cell as these nitrogenous bases are read by the ribosome in the form of triplets called codons where each codon codes for specific amino acids. These amino acids bind to each other via peptide bonds to form proteins.
Thus, these nitrogenous bases control the important property of the cell.
Answer:
C
Explanation:
Before the earthquake the gene pool of the parent population was bigger and carried different alleles for a lot of genes.
After the killing of 98% of the population, the surviving one has an incomplete representation of the original gene pool. We can think of this as a gene bottleneck ; the new allele frequencies will be different that the parental population. IE: broadness of stripes has a higher frequency after the earthquake.
<span>He needs to keep everything the same — or controlled — in the control group plant and the experimental plants, so that the only difference between the groups is the amount of sunlight that they get. </span>
The answer is through facilitated diffusion. It is then called as the transport of substances in a biological membrane from a higher concentration to a lower concentration area though carrier proteins. Hope this is the right answer and would be of help.
