Answer:
Protection, support and shape
Photosynthesis and respiration are interrelated as stated in the last option
Swimming works the heart and lungs. This trains the body to use oxygen more efficiently, which is generally reflected in declines in the resting heart rate and breathing rate.
All you have to see whether or not a duplication mutation has occurred, is simply count the number of nucleotides present in the original DNA strand and compare that number to the nucleotides present in the options. The only sequence which has substantially more nucleotides would be C. Thus we know that certain portion had been duplicated if the sequence after the mutation is in fact C.
Answer:
Photosynthesis will be affected or may not occur.
Explanation:
This is because palisade mesophyll are packed cells and have cylindrical shape with chloroplasts. Chloroplast are present here which control chlorophyll and this area specialises in absorbing light energy from the sun efficiently. If it is below spongy mesophyll, it's ability to absorb light energy is affected as there is an hindrance layer, and when chlorophyll couldn't absorb light energy, photosynthesis cannot occur.
