Answer:
The complement system or complement cascade is an essential part immune system that increases the ability of the immune cells such as phagocytic cells and antibodies to kill and remove foreign bodies such as microbes and removes the damaged or infected from the cells of an infected organism.
The complement system utilizes the classic pathway to destroy cell walls or membrane of antigen or microbes, however, it sometimes also use alternate pathway for certain organism
Large numbers of activated complement proteins are produced by the complement system that binds and, opsonizing microbes for internalization by phagocytes having receptors for a complement. It is important for innate defense
Cell is the smallest unit of an organism that can have a separate existence.
<h3>What is a cell?</h3>
This question is incomplete but I will try to help you as much as possible. The term cell is the smallest unit of an organism that can have a separate existence.
We know that all cells come from pre existing cells and complex multi-cellular organisms evolved from simple unicellular organisms. This forms the basis of the cell theory.

Answer:
C) Non-protein-coding DNA that is transcribed into several kinds of small RNAs with biological function.
Explanation:
The genome of humans consists of a variety of protein-coding and non-protein coding sequences. The protein-coding sequences are the sequences which can get translated into the protein sequences.
When the genome was sequenced, it was expected that the size of these coding sequences will be larger but the sequences came to be smaller. This shows that the rest of the genome is made of the non-coding sequences.
The importance of these non-coding sequences is that they do not form the proteins but they can undergo transcription and form the variety of RNA molecules like the regulatory RNA, the ribosomal RNA and others.
Thus, Option-C is the correct answer.
The answer is A. No mate is required for asexual reproduction
Answer:
Haploid number of chromosomes.
Explanation:
Before fusion of sex cells i. e. sperm cells and egg cells, there are half number of chromosome present in each sec cell because in the sex cells meiosis occurs. Meiosis is a type of cell division in which a single parent cell divides into four daughter cells having haploid chromosome i. e. half number of chromosomes in each daughter cell. So when these sex cells fuse together, they form a diploid organism.
