Answer:
D. plants use carbon dioxide to make glucose/sugar
Answer:
The second stage.
Explanation:
Epinephrine is a hormone that is released by the glands over the kidneys that initiate a fight-or-flight response sequence in the body which starts with the segregation of the hormone and ends with the release of glucose into the bloodstream by the liver to provide energy required for the situation by the body.
The liver cells acts in the second stage of the epinephrine initiated signal with glycogen phosphorylase enzyme. The released epinephrine activates an enzyme called phosphorylase kinase and that in turn activates glycogen phosphorylase. Lastly glycogen phosphorylase reacts to epinephrine and releases another enzyme to remove the phospate from the glycogen phosphorylase group to form glucose that will be released into the bloodstream for energy.
I hope this answer helps.
The pathway will be;
The body cells becomes infected with a virus= then new viral proteins appear = class I MHC molecule-antigen complex displayed on cell surface.
Cytotoxic T cell is a T lymphocyte that kills cancer cells, cells that are infected or cells that are damaged in other ways. They are activated on the surface of antigen-presenting cells, which mature during the innate immune responses triggered by an infection.
Infertility is the incapacity to conceive an offspring while erectile dysfunction is the incapacity to get aroused so as to engage in sexual intercourse (mostly in men).
Erectile dysfunction could be caused by stress, cardiovascular diseases, and diabetes. Therefore treating it requires maintaining a healthy lifestyle of nutrition and exercise.
Infertility can be caused by disorders of reproductive organs such as endometriosis and occlusion in the tubes. This can be treated by assisted reproduction (IVF), corrective surgery and education.
Pluto
Nasa's New Horizons mission made a close pass of Pluto this week. For more than 70 years, Pluto was one of nine planets recognised in our Solar System. But in 2006, it was relegated to the status of dwarf planet by the International Astronomical Union (IAU)
