Answer:
The correct answer is c) logistic
Explanation:
Logistic growth occurs during a population growth when the resources are limiting. During logistic growth sigmoid (S-shaped) growth curve is produced when population size is placed over time.
In logistic growth first the population increases slowly then after some time it increase on the logarithmic phase until it levels off near the maximum carrying capacity due to environmental resistance. Beyond this maximum carrying capacity growth rate does not increase and becomes constant.
This generates an s-shaped curve called a sigmoid curve which shows the logistic growth. So the correct answer is c.

Answer:
the humus contains the minerals necessary for chlorophyll synthesis
Explanation:
<em>The yellowness of leaves in plants can be attributed to inadequate chlorophyll in the plant</em>. The chlorophyll is responsible for the greenness appearance of the leaves of plants and when it is present in inadequate quantity, the leaves appear yellowish in color.
<u>Some of the minerals necessary for the formation of chlorophyll include magnesium, nitrogen, and iron</u>. It thus means that the humus supplied to the soil of group 1 plant has the necessary minerals to synthesize chlorophyll while the soil of group 2 plants is deficient in some or all the minerals required for chlorophyll synthesis.
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.
