Answer:
The leukocyte, commonly known as a white blood cell (or WBC), is a major component of the body’s defenses against disease. Leukocytes protect the body against invading microorganisms and body cells with mutated DNA, and they clean up debris. Platelets are essential for the repair of blood vessels when damage to them has occurred; they also provide growth factors for healing and repair.Although leukocytes and erythrocytes both originate from hematopoietic stem cells in the bone marrow, they are very different from each other in many significant ways. For instance, leukocytes are far less numerous than erythrocytes: Typically there are only 5000 to 10,000 per µL. They are also larger than erythrocytes and are the only formed elements that are complete cells, possessing a nucleus and organelles. And although there is just one type of erythrocyte, there are many types of leukocytes. Most of these types have a much shorter lifespan than that of erythrocytes, some as short as a few hours or even a few minutes in the case of acute infection.
Hope this helps :)
Explanation:
Humans produce few offspring throughout multiple reproductive episodes.
Explanation:
According to the prediction of Life history theory that organisms are capable to increase their fitness who is either by producing many offspring or by producing fewer and also high-quality offspring. Offspring investment is extended by human but some it is obscured by their cultural mechanism.
In human species the quality and quantity doubt has been empirically shown in the species which produce litters or clutches, where their litter size is large which leads the small offspring size and their growth rate became slow and due to this their survival is getting reduced.
The Comparative analyses also help a negative and the inter-specific relationship between their reproductive rate and their offspring size
