Answer:
C. 50 drops/hr
Explanation:
As we can see in the description of the graph above, 50 drops/hr was the rate of water fall that was most successful in plant growth. This is because with this rate, the seeds germinated more quickly, the seedlings showed a strong and fast vegetative growth, besides that at the end of 5 days, it was observed that germination of almost 100% of the seeds occurred. These facts cannot be observed with the other waterfall rates, so the correct answer is 50 drops/hr.
<span>Answer: There would be more cellular damage
from harmful products of the light reactions of photosynthesis.</span>
<span>Photorespiration
is a light dependent reaction that uptake molecular oxygen and release of
carbon dioxide from organic compund. Photorespiration is linked to
photosynthesis by ribulose-1,5-bisphosphate carboxylase. However, consequence of mutation in plant due to
photorespiration deficiency will result into </span>more cellular damage from harmful products of the light
reactions of photosynthesis.
Answer: Wo meiyou xiansuo
Explanation:
The right option is; extreme traits
Disruptive selection events select for extreme traits.
Disruptive selection is a type of natural selection in which organisms with extreme traits are favored (such as in reproduction) over organisms with intermediate traits. This type of selection results in increased traits differences with increase in frequency of the alleles for the extreme traits. Disruptive selection can lead to the digression in a species line.
Answer:B. Sunlight provides energy to producers
Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.
