Your bones and muscles work together to support and move your body. Your respiratory system takes in oxygen from the air and gets rid of carbon dioxide.
The question is incomplete as it does not have the options which are:
- going to a tailor and having a suit made to fit you
- selecting a lottery prize-winner by means of a random drawing
- going to a shoe store and trying on shoes until you find a pair that fits
- ordering the lunch special at a restaurant without looking at the menu
- picking out a video that you haven't seen yet
Answer:
Going to a shoe store and trying on shoes until you find a pair that fits
Explanation:
Antibodies are the immunoglobulin molecules secreted by the B cells which help the body providing the immunity as they interact with the antigen and help immune system to produce a response.
The variety of the B cells are produced by the body in response to different antigens which produce different type of antibodies. This interaction of antigen and antibodies is known as the complementation and just appear like if you are going to a shop to buys a pair of shoes and tries different shoes to find the best shoe of best size.
Thus, the selected option is correct.

After hundreds or even thousands of generations both alleles for sickle cell anemia are still common in those of African ancestry. This is supported by two mechanisms: heterozygote advantage and gene flow.
Heterozygote advantage
When an allele is said to be heterozygous, it is carrying one copy of a gene. For example if one carries a copy of sickle cell allele, it will stay in the population even after many generations — natural selection will not be able to remove it and it will be passed on through generations. So, having one copy of that allele is advantageous but not deleterious.
Gene flow
With humans migrating throughout the different parts of the world, sickle cell allele is passed from one person to another or in different populations. It is actually advantageous to have one copy of this allele especially if there’s malaria in the area, which the allele is resistant.
