Nonspecific defenses include physical and chemical barriers, the inflammatory response, and interferons. Physical barriers include the intact skin and mucous membranes. These barriers are aided by various antimicrobial chemicals in tissue and fluids.
Nonspecific defenses include anatomic barriers, inhibitors, phagocytosis, fever, inflammation, and IFN. Specific defenses include antibody and cell-mediated immunity.

From right to left.
1) Cytokinesis is almost
finished, so it’s the end of Telophase
2) The chromatids have just
split up and are migrating to each pole, so it’s Anaphase
3) All chromosomes are in the
equatorial plane, so it’s the end of Metaphase
4) The chromosomes are in the
poles and cytokinesis has just started, so it’s the beginning of Telophase
5) The spindle apparatus is
complete and the chromosomes are moving to the equatorial plate, so it’s the
beginning of Metaphase
6) The spindle apparatus is forming,
so it’s Prophase
If you want to put them in
chronological order, it’s like this:
6-5-3-2-4-1
Answer:
Oxygen
Explanation:
Oxygen is the by product of photolysis during photosynthesis whereby water molecules are split to form protons (H+ ions), electrons and oxygen (by product).
Oxygen is not needed during any of the reactions in photosynthesis and Calvin cycle and will not affect the rate of photosynthesis or possibility of photosynthesis occurring. However, it will affect the process of aerobic respiration instead.
Carbon dioxide is needed in carbon fixation during the Calvin cycle. Without it, 6 carbon sugars cannot be formed.
Water is needed for photolysis to produce protons (maintain the electrochemical gradient) and electrons (to replenish lost electrons)
Chlorophyll are pigments that harvest light energy to excite electrons produced from photolysis of water to be passed down the electron transport chain.
Light is needed as a source of energy to energise the electrons
The answer to your question is true.
