Answer:

A

Explanation:

A. The optimum pH of the enzyme is 6.6.  - this is true. The optimum pH of the enzyme is where its activity is the highest. On the graph, this is pH 6.6 (activity at 100)

B. The optimum pH of the enzyme is 5.8.  - this is false, the activity of the enzyme peaks at 6.6 (100), at 5.8 the activity is 80

C. The enzyme's activity is greater around pH 8.0 than around  pH 5.0  - This is false, the activity at pH 5 is 50, whereas at around 8 it is 20.

D . The enzyme's activity continually increases as pH increases  from 5.0 to 9.0 - this is false. The activity drops between pH 6.6 and pH 9.

seeds that are planted upside down are still able to grow into mature plants which explanation best explains this phenomenon?​
pav-90 [236]

Answer:

This question is incomplete but the completed question is below

eeds that are planted upside down are still able to grow into mature plants. Which explanation best explains this phenomenon?

(a)The roots change into branches, and the branches turn into roots.

(b)The roots grow toward the force of gravity, and the shoots grow away.

(c)The plant will become a smaller version of a mature plant.

(d)Roots always grow toward the dark, and shoots grow toward the light.

Two options appear to be correct here: options B and D

Explanation:

Regardless of the direction the seed is planted, the seed has the ability to re-position itself via the help of growth hormones that respond to gravity and redirect the seed into the proper orientation. However, after re-orientation of the seed, the root grows toward the direction of gravity (a process known as gravitropism) while the shoot grows toward the direction of sunlight (a process known as phototropism). Even though two options appear to be correct here, the most correct option based on he question is b
