Which process occurs during the light-dependent reactions in photosynthesis?
kobusy [5.1K]

Answer:

A. Water molecules are split.

Explanation:

The light dependent reactions of photosynthesis require the energy in sunlight to proceed. Structures called photosystems which contain chlorophyll absorb the light from the sun to generate excited electrons, which are transferred to electron carriers ATP and NADH.

These electron carriers are used in the light-independent reactions of photosynthesis.

During this process,  the high energy electrons are passed to an acceptor molecule and replaced with an electron from water. This splitting of water produces H+ ions and oxygen as a byproduct. The splitting of water is called photolysis

Community ecologists study the factors that determine the abundance of different species. The Abundance of three algae species (
Tema [17]

Answer:

Explanation:

Given that:

The abundance of three algal species in Lake A is now represented by the vectors:

[97, 84, 43] and [100, 80, 50]

Now if we look at Lake A, the change occurring in the vector of algae species can be determined as:

a = [100 -97, 80 - 84. 50 - 43]

a = [3, -4, 7]

Thus, the magnitude of that change is:

|a| = \sqrt{(3)^2 +(-4)^2+(7)^2}

|a| = \sqrt{9+16+49}

|a| = \sqrt{74}

|a| =8.6 \ mg/mL

The abundance of three algal species in Lake B is now represented by the vectors:

[25, 59, 22] and [20, 63, 15]

At Lake B, the change occurring in the vector of algae species can be determined as:

b = [20 -23, 63 - 59. 15 - 22]

b = [-3, -4, -7]

Thus, the magnitude of that change is:

|b| = \sqrt{(-3)^2 +(4)^2+(-7)^2}

|b| = \sqrt{9+16+49}

|b| = \sqrt{74}

|b| =8.6 \ mg/mL

Hence, for both Lake A and B, the magnitude of change is the same.
