Following are the statements:
1. Main phagocytes in circulation
2. Like eosinophils, they are involved in inflammation and allergic reactions
3. Phagocytic cells that leave circulation and differentiate into macrophages
4. Display no antigen specificity but are active against tumor and virally infected cells
Answer:
1. Neutrophils
2. Basophils
3. Monocytes
4. Natural killer cells
Explanation:
Neutrophils can be described as the most abundant type of white blood cells. They make up to 55%- 75% of the immune system.
Basophils can be described as white blood cells which are made in the bone marrow.
Monocytes can be described as white blood cells which are the largest and differentiate into macrophages and myeloid lineage dendritic cells.
Natural killer cells can be described as white blood cells which play a role in providing innate immunity.
The correct answer is centrosome.
<span>The centrosome is the main microtubule organizing centre of the animal cell and it is involved in the regulation of cell-cycle progression. During the mitosis, the centrosome microtubules can interact with the chromosomes to build the mitotic spindle.</span>
Answer:
Carrying capacity
Explanation:
The scarcity of the resources of the small forest area could serve as an indication that the forest area has reached its carrying capacity. The carrying capacity of an ecosystem refers to the number of organisms that the ecosystem can comfortably support indefinitely.
Exceeding the carrying capacity will result in scarcity of resources
Answer:The correct answer is C
Explanation:
"heterozygous" for a trait = When an organism has one dominant allele and one recessive allele for a trait. Most of the time, the organism will express the dominant form of the trait.
