A. Hundreds

This is because only around 1000 sperm cells will enter the fallopian tube. Only around 200 sperm cells make it to the egg.

Most red deer who successfully reproduce have about four fawns during their lifetimes. However, a small percentage of red deer p
Rasek [7]

Answer:

Natural selection will favor red deer that produce a dozen or more offspring that survive for at least a year.

Explanation:

Natural selection results in adaptation, which means the increase of the aptitude phenotype.  Aptitude is the contribution of each genotype to the next generation.

Natural selection is the result between the individual phenotype and the environment that determines the destiny of genes. It is the differential capability of individuals to leave offspring.

Aptitude (or fitness) is the phenotype that results in the survival, fertility, and capability of having a mate. It is a way of measuring the individual ability to leave fertile offspring. Aptitude must be significant to the natural selection act in its favor.  

Natural selection, eventually, will favor red deer that produce a dozen or more offspring that survive for at least a year. These animals have more chances of leaving fertile descendants that will be able to grow, develop, survive, and reproduce. They have a higher aptitude than those individuals that only have four fawns during their lifetimes. These animals have fewer probabilities of leaving survival descendants able to reproduce.

The following DNA is being replicated and the origin of replication is in the middle of the sequence and marked with three stars
xxTIMURxx [149]

Answer:

5'GATCGTAA3'

5'ATTCTAGA3'

Explanation:

As requested in the question above, the primers were presented with 8 nucleotides, with the nitrogenous bases of the DNA, and in the 5'-3 'direction.

Primers are small fragments of DNA that are used by DNA polymerase to form new strands. The primes attach to pieces on the ribbon, through the complementarity of the nitrogenous bases, serving as a template for the DNA polymerase to create the new ribbon.

DNA polymerase uses primers at the origin of replication, and can follow the path from the right or from the left, depending on the primers used, for this reason, this question has two answers.
