Answer:
c. Mitosis results in the formation of two new cells with 23 pairs of chromosomes.
Explanation:
A and B are meiosis and D is wrong
Answer:
Cytotoxic T cell
Helper T cell
Explanation:
Adaptive immune system is a part of the immune system initiated only when there is an attack by a pathogen or foreign substance. The adaptive immune system is beckoned on when the infection is insurmountable for the body's first line of immunity, which is the innate immune system.
The adaptive immune response is triggered by the white blood cells called LYMPHOCYTES. Lymphocytes consists of T cells and B cells. T cells are either cytotoxic or helper T cells. The cytotoxic T cells kills the cells infected with the virus while the Helper T cells activate every other cell involved in the immune process.
Answer:
Question 1 - c. vv
Question 2 - b. Any of the non-sex chromosomes
Question 3 - b. Eukaryotic
Explanation:
Question 1
As explained, the gene for normal wings (V) is a dominant gene while the gene for the vestigial wings (v) is recessive. Dominant genes overpower any recessive genes.
VV - Two dominant genes will produce the dominant trait
Vv - The dominant gene (V) overpowers the recessive gene (v) and produced the dominant trait.
This means that the only way to have a fly with vestigial wings is if the fly has 2 recessive genes. This means that our answer is c. vv
Question 2
An autosome is defined as any of the non-sex chromosomes.
Question 3
Linear chromosomes are a type of chromosome most often found in eukaryotic cells. On the other hand, prokaryotic cells usually have circular chromosomes. This means that our answer is b. eukaryotic

The correct answer is C. Genetic analysis
Explanation:
In biology, two organisms have a phylogenetic relationship if they share a common ancestor and therefore have genetic similarities although in most cases there are also similarities in morphology, physiology, etc. However, two organisms might have similarities in morphology and physiology without genetic similarities. Due to this, if you need to determine whether two species are related or not the best method is a genetic analysis as only those organisms that share a common ancestor (phylogenetic relationship) are genetically similar.
