Answer:
At the very bottom
Explanation:
When examining a cross section of rock layers, the oldest layer is on the bottom. This is because over time, newer rock layers continued to form on top of the oldest one.
Answer:
Just one round without DNA repair
Explanation:
When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error
Answer:
<u>a. the production of ATP</u>
<u />
Explanation:
Photosynthesis is type of biosynthesis that produces glucose from the reactants sunlight, carbon dioxide and water. It happens in two phases of the chloroplast, the light-dependent and light-independent reactions. In a light reaction that stimulates photosystems, pigments such as chlorophyll absorb light energy at specific wavelengths. Here,
- Light energy stimulates photosystem complexes formed from chlorophyll. Photosystem II then absorbs and transfers light to a reaction core.
- Water undergoes hydrolysis or splitting to yield an electron, a proton (H+) and oxygen.
- energy is passed along the electron transport chain, where it forms builds up H+ and an electrochemical gradient in the thylakoid space
- These protons pass through the ATPase enzyme embedded within the membrane, into the stroma, generating ATP from ADP.
- NADPH is generated from NADP+
Answer:
interaction between two different organisms living in close physical association, typically to the advantage of both.Compare with antibiosis.
