Answer: B
Explanation:
The T helper cell needs to acttivate the T cyctotoxic cell in order for the Tc cell to go do its work.
Once the TC cell is active it interacts with MHC-1 proteins on the surface of the infected host cell, this allows the Tc cell to recignise the host cell and begin secreting cytotoxins (perforins and granzymes) in order to degrade the infected cell and cause apoptosis (controlled cell death)
Answer:
Species
Explanation:
Such as humans, we are a species because we all look similar and can reproduce with one another.
Answer:
The correct answer will be option- B and C.
Explanation:
The cellular respiration is the process of forming energy molecules through oxidation of food. The cellular respiration takes place in four stages: glycolysis, link reaction, Krebs cycle and electron transport chain.
The glycolysis converts the glucose molecules to form two molecules of pyruvate and two ATP molecules but the total number of molecules formed in cellular respiration is between 36-38 ATP molecules. The electron flow takes place in the electron transport chain which helps in the generation of the proton motive force used to produce ATP molecules.
Thus, Option-B and C is the correct answer.
I really hope this helps!
The main dangers worldwide are population growth and resource consumption, climate change and global warming, habitat conversion and urbanisation, invasive alien species, over-exploitation of natural resources and environmental degradation.
Answer:
<em>a. Cross-sectional study</em>
Explanation:
A cross-sectional analysis <em>includes at one particular point in time looking at data from a population.</em> Participants are chosen based on specific variables of interest in this type of study.
For developmental psychology, cross-sectional experiments are often used, but this approach is also used in many other fields, including social science and education.
