Answer:
Adaptive immune responses are triggered by activation of antigen-specific T cells that produce antibodies against foreign antigens such as, for example, harmful viruses. These immune responses are useful to eliminate dangerous molecules from the body. In a normal immune reaction, the antibodies produced by T-cells target antigen molecules in order to be subsequently absorbed by phagocytic macrophage cells.
Autoimmune diseases are triggered by the response of the adaptive immune system against self-antigen molecules. Since the immune system can not eliminate antigens from the own body, this immune reaction generates an excessive inflammatory response, and it may lead to the damage of tissues and organs.
Answer:
The Gram-negative diplococci <u>Neisseria </u>are pathogenic microbes that infect mammalian mucous membranes, and include the species which causes gonorrhea.
Explanation:
Options for this question are:
- <em>Streptococcus
.</em>
- <em>Coxiella
.</em>
- <em>Neisseria
.</em>
- <em>Listeria
.</em>
- <em>Haemophilus.</em>
Bacteria of the genus Neisseria are Gram-negative, with a rounded morphology that are associated in pairs, so they are called diplococci. They are aerobic microorganisms, no more than 1 micrometer in diameter, immobile and not sporulated.
Their biological importance is due to the fact that they cause diseases in humans, such as bacterial meningitis -caused by N. meningitidis- or gonorrhea, associated with N. gonorrhoeae.

Answer:
Glucose is produced by plants through photosynthesis. In this process, the plant uses light energy from the Sun to convert carbon dioxide and water into glucose and oxygen. Algae and certain bacteria and other unicellular organisms also produce glucose through photosynthesis.
