Answer:

b). activation of T cells

Explanation:

An APC (antigen-presenting cell) can be described as an immune cell, which detects, uptakes, and informs the acquired immune response when an infection takes place. B cells, macrophages, and dendritic cells are antigen-presenting cells.

These cells play an important role in activation of T cells. T cells are unable to recognize soluble or free antigens and can only recognize antigens processed and presented by carrier molecules, such as MHC molecules.

Presence of MHCII molecules is a defining feature of APCs that process and present antigens to T cells. Hence, all antigen-presenting cells help in activation of T cells.  

Thus, the correct answer is option (b).

What happens to predator populations when prey populations are scarce? Why?
GenaCL600 [577]
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.

The millions of sequences were not put up together from their end and had no repeating non-coding sequences.

Explanation:

Celera Venter of Gene Myers started working in collaboration with the Human Genome project which was designed as a revolutionary concept of sequencing of human genome at a large scale. Myers break through the traditional method of sequencing and proposed of an idea of sequencing in a unique way.  

He suggested the method of breaking genome copies and then sequencing them together using LINEs. However, the declaration of this proposal by the Human project had certain failures at first as it lacked the non-coding repeating sequence.
