B.) crossing over, this is when chromosomes exchange DNA
Answer: There is a 50% chance that the offspring will inherit Huntington's disease
Explanation:
Huntington's disease is expressed by a dominant allele.
Since the father is heterozygous for Huntington's disease, his genotype would be as follows:Hh
Even though he carries a normal allele, the dominant allele is disease causing and thus masks the effects of the normal allele, therefore he expresses the disease.
The mother does not have Huntington's because she is homozygous recessive, in other words, she carries 2 copies of the normal alleles.with the genotype hh.
If you do a punnet square, and you cross the mother and father, the following genotypes can be produced:
Hh, Hh, hh, hh
Therefore, there's a 50% chance that the offspring will inherit the disease causing allele and 50% chance that the offspring will not inherit it.
Answer:
Predation.
Explanation:
Limiting factor refer to resources or environmental condition that limit the growth or distribution of organisms in the ecosystem. This make the organism not to occupy their original niche. Predation is a limiting factor. Predation refer to ability of an organism to prey on another organism or capture it. Predation is a density dependent factor whose effect on population determined the total size of the population. Fox chasing pika is an example of predation.
I will revise the simulation so users can evaluate the role of human activity in the pH of the ocean by lowering the temperature.
<h3>What is pH?</h3>
This is referred to as power of hydrogen and is the measure of acidity or alkalinity of a substance.
The variables which would be changed in the simulation to accomplish it is the increase in oxygen levels.

These are the statements
that apply;
viruses are not able to reproduce outside of a host cell
<span>have
DNA or RNA,
not both</span>
are unable carry out metabolic processes to generate ATP
viruses do not have a cellular structure
Viruses, though, have some living characteristics such as; they mutate and reproduce (rather inside
the host cell)
