Answer:
True to some extent...
Explanation:
We can use bio-informatical tools like MEGA to see that to what extent an amino acid sequence shares ancestry with the other one. But these tools are based on statistical methods and mathematical modelling that make them unreliable as compared to the real world observations.
The right answer is A: Enzyme activity decreases at these temperatures
Temperature influences the activity of the enzymes responsible for assisting with chemical reactions in the Calvin cycle. When temperatures are low, enzyme activity is slow. As temperatures increase, the activity of the enzymes that assist in these chemical reactions also increases to a certain extent, which is the optimal response to temperature. It is at this point that the rate of photosynthesis of plants is the highest.
As the temperature continues to rise beyond this point, the enzyme activity decreases until photosynthesis stops. It is important to remember that the rate of photosynthesis in C3 plants is higher in cold conditions, whereas it is the opposite in C4 plants.
Answer:
Chitin
Explanation:
This glucose derivative is in fact the main building block of cell walls in not only arthropods (including the shrimp), but also fungi and insects, and also has a structural function in the scales of fish. The most similar commonly-known substance in terms of function is keratin, which makes up our hair and nails.
Question 2 is ansethosphere
Question 3 is high pressure(i think)
