<span>c. Metaphase
</span><span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size. </span>
Answer:
The correct option is B (natural killer cells).
Explanation:
Natural killer cells: They are defined as the type of cytotoxic lymphocyte which are critical to the innate immune system. The NK cells play an important role in to provide rapid response to tumor formation, virus infected cells, and acting after three days of infection.
While cancer cells die, they release some antigens, than these antigens are recognized by the immune system, and later they are presented on the immune cells which are known as antigen presenting cells. So, if these cells are absent than they increase the chances of developing malignant tumors.
Answer:
Yes you are correct.
Explanation:
Number one is the rough ER not the nucleus. Number 3 is the mitochondria not the Ribosomes. This is an animal cell so there can not be a cell wall. There are exactly 3 small vacuoles in an animal cell so yes, you are correct.
When applying rigid-body mechanics to the study of human beings, the assumption made is Option B.The body does not deform by bending, stretching, or compressing.
<u>Explanation</u>:
Rigid body mechanics is a body in which the gap between any two points will be constant in time, despite of external forces. The body cannot be deformed at any circumstances be it under application of any force. The forces acting over the body gets divided into two groups one is external, which shows the action of different bodies on the rigid body under force and internal force that binds the body together making it rigid. Body changes its motion only in case of pull against some external object.
