Answer:
A. fast twitch fibers primarily perform anaerobic respiration.
Explanation:
Fast twitch fibers are helpful in generating quick energy from anaerobic respiration during exercise, sprinting or jumping. Anaerobic respiration is a type of respiration in which energy is released from glucose molecules in the absence of oxygen by the mitochondria of the cell. The energy which is produced produced is very low as compared to aerobic respiration.
Answer:
North
Explanation:
it will migrates towards north
sugar maple trees shows migration pattern during climate change conditions which is an indication of global warming.
Answer:
.45 from mom, .05 from dad
Explanation:
Given that:
the mother's genotype is AZ/az
i.e AZ = 50%
az = 50% (parental)
But we were also told that the recombination rate is 10% which will like wise affect the mother's genotype
So 100% -10% = 90 % of the mother's genotype
We have a new genotype
AZ = 45%
az = 45% (parental)
Therefore the probability of az gamete from the mother = 
= 0.45
Similarly; the genotype of the father is: Az/aZ
This is an heterozygous father who is diploid hence, there is a remarkable presence of two copies of each autosomal chromosome.
Az is the allele of the genes in one chromosomes and aZ is the allele of the genes in the other.
The gametes of this self cross are: Aa, AZ, az, zZ
Therefore; the recombinants are:
AZ
az
Since there are 10% recombinant; then
AZ = 5%
az = 5%
Therefore the probability of az gamete from the father = 
= .05
Answer;
-Nucleotides
Explanation;
-Nucleic acids are polynucleotides, that is, long chainlike molecules composed of a series of nearly identical building blocks called nucleotides. Each nucleotide consists of a nitrogen-containing aromatic base attached to a pentose (five-carbon) sugar, which is in turn attached to a phosphate group.
-A sugar-phosphate backbone joins together nucleotides in a DNA sequence. The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
