Collateral blood flow is an enlargement vessel that opens to cause a detour around a blockage. When an artery in the brain is block (TIA) open collateral vessels can allow blood to bypass the blockage to restore blood flow to the affected area. <span />
I think the correct graph would have light intensity on the x-axis (because light intensity is the independent variable) and a measure of photosynthetic rate (either O2 evolution or CO2 consumption) on the y-axis (because the rate of photosynthesis is the dependent variable)... hope this helps
Answer:
Abiotic factors are the non-living factors that support the life on earth. The make up the environment suitable for the survival and growth of the living species like soil, water, sunlight and others. Biotic factors are the living species like plants, animals, microbes and humans.
A cow is a herbivores animals, that utilizes grasses,shrubs and leaves as food, it also need water to drink and oxygen to breath and respire. Therefore, the two example of abiotic factors which a cow will experience in it's environment is oxygen and water and biotic factors will be grasses and another member of the same species as mate, to undergo copulation and produce a new offspring.
Answer:
Please find the explanation below
Explanation:
This question is describing the processes involved in photosynthesis. In the light-dependent stage of photosynthesis, specifically photosystem II (PSII), water is oxidized in a process called PHOTOLYSIS OF WATER. This process produces electrons and Hydrogen ions (H+). The electrons produced via this process is accepted by NAD+ to yield NADH.
The NADH is an electron carrier produced during the light-dependent stage and used to reduce 3-phsophoglycerate (PGA) produced in the light-independent stage to glyceraldehyde-3-phosphate (G3P).
Answer:
C. Both (a) and (b)
Explanation:
Hunting, destroying habitats, polluting and introducing non-native species can cause extinction.
