Answer:
The pig's genotype is Tt
Explanation:
As mentioned in the question that curly hair allele T is dominant over straight tail allele t.
A heterozygous organism is that in which both alleles for a trait are different. Since Curly hair allele T is dominant over straight tail t, it means that the pig with curly tail and heterozygous genotype will definitely have a genotype of Tt.
Hope it helps! :)
The carbon cycle is the process in which carbon travels from the atmosphere into organisms and the Earth and then back into the atmosphere. Plants take carbon dioxide from the air and use it to make food. Animals then eat the food and carbon<span> is stored in their bodies or released as CO2 through respiration.

Answer:
B) genetic variation needed for a population to evolve
Explanation:
Mutations are important because they bring about the genetic variation needed for a population to evolve.
- Mutation brings about changes in the DNA sequence of an organism.
- Most times, mutation results when an organism tries to adapt and evolve to unfavorable conditions.
- Mutation can originate from mistakes in DNA sequencing.
- It can also be due to environmental influences.
The amino acids would change resulting in totally different proteins which is also called a frameshift mutation.
when no oxygen is present, there is no electron acceptor, thus pyruvate goes through a process known as fermentation which usually forms lactic acid or ethanol as a by-product. During lactic acid fermentation, pyruvate is reduced directly by NADH to form lactate as a waste product, with no release of CO2.
