Answer:
Please find what occurs in the single nucleotide-pair substitution below
Explanation:
Single nucleotide-pair substitution is a type of point mutation as stated in this question. Point mutation is when one nucleotide base (single) is affected in the sequence. In this single nucleotide-pair substitution, ONE nucleotide base is substituted by another base.
For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG. Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.
The first one. Becuse there are more grey particuls, wich difuse faster.
Answer: Basal metabolism rate or rate of energy expenditure
Basal metabolism rate <span>calculates the amount of calories that the body needs, in twenty-four hours,

Answer:
Innate immune response.
Explanation:
TLR also called toll-like receptors play crucial role in innate immune response. They are single spanning proteins and are present on dendritic cells and macrophages.
The pathogen when enters the body via skin or epithelial of mucosal membrane, they are recognized by TLR that further activates the immune response.
Meiosis increases genetic variation due to random segregation which occurs.
In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).
