Answer:
Primary adaptive response
Explanation:
After the first exposure to an antigen, a primary adaptive response stimulates growth and multiplication of antigen-reaction cells. phagocytic immune response secondary innate immune response hyperactive cytotoxic response primary adaptive immune response
1) Because we are constantly discovering new species of organisms, the system of classification is growing.
2) In order for scientists to write, learn, and retrieve data about organisms, there most be an organized filing system in place.
Answer:
Hello!
7. A totipotent stem cell is a cell capable of differentiating into any cell required by the body.
A pluripotent stem cell can differentiate into any body cell but it is not required for the growth and development of the embryo.
Multipotent stem cells can differentiate into any cell in a specific cell lineage. For example, a red blood cell or white blood cell.
An oligopotent stem cell can differentiate into one of a specific cell type.
A unipotent cell is fully differentiated and specialized and can only produce more of its own cell type.
5. True. Tissues are a group of cells with the same structure and function.
Explanation:
Stem Cells:
A stem cell is an undifferentiated cell that has the capacity to differentiate into any cell of the body under specific conditions.
- Totipotent stem cells are the first embryonic cells produced by the division of the zygote. They can differentiate into any cell required for development.
- The embryonic cells formed through the division of the zygote are pluripotent cells.
The correct answers are gluconeogenesis and glycogenolysis.
Glucose is the prime energy source, which is utilized by the body. Glucagon refers to the peptide hormone, which enhances the levels of glucose in the body when its amount is critically low in the blood.
The upsurge in the number of glucose levels in the bloodstream is encouraged by the processes, gluconeogenesis, and glycogenolysis. Gluconeogenesis refers to the metabolic pathway, which generates glucose molecules, this generally occurs in the liver.
Glycogenolysis refers to the biochemical dissociation of glycogen molecules to glucose. It takes place in the liver tissues.
