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.
Answer:
immune system
Explanation:
The adaptive immune system reacts specifically to pathogens (germs). It is able to recognize attacking pathogens and fights against certain antigens or foreign substances. The next time a known antigen is encountered, the adaptive immune system can respond faster.
After collecting evidence that concludes that the current plan to manage the Alaska crab fishery makes it only a potentially renewable resource, m<span>ore research should be done into the reproductive behaviors of the different species. This solution tries to solve the problem at its roots. That is, if the management determines why there are fewer species based on their reproductive behaviors, certain changes can be made in order to create an environment that will enhance their reproduction. </span>
