_____ splits water into 1/2 O2, H , and e- . A structure of a thylakoid. Letters from A to E indicate definite structures. Lette

Sauron [17]

The luminous reactions begin when light reaches photosystem II. The water molecules provide electrons to the photosystem, releasing oxygen and protons. The letter A represents photosystem II that splits water.

-----------

1. Luminous energy is trapped by chlorophyll in Photosystem II.

2. When the pigment molecules absorb light, electrons provided by water molecules get in a higher energy level.

3. The excited electrons go through the electron transport chain from Photosystem II to a less energetic level in photosystem I.

4. When the excited electrons leave photosystem II, they are replaced by new electrons extracted from the water molecules.

5. Luminous energy absorbed move the electrons from the photosystem I to another electron acceptor, from where they get transported again and used to produce NADPH molecules.

6. When electrons leave Photosystem I, they are replaced by new electrons coming from photosystem II.

7. When the water molecule breaks down, hydrogen ions remain in the thylakoid lumen, from where they are pumped to the stroma by the ATP synthase.

8. The released energy is used to produce ATP molecules.

9. Hydrogen ions go back from the stroma to the thylakoid compartment.

Occurs when the individual inherits only one (female) X chromosome

algol13

According to the research, Turner syndrome is a condition that occurs when the individual inherits only one (female) X chromosome.

<h3>What is Turner syndrome?</h3>

It is a genetic condition that is due to the lack of an X chromosome or part of it and can include characteristics such as delayed or incomplete development of puberty.

It can be diagnosed at birth or during childhood, puberty, or adulthood.

Therefore, we can conclude that according to the research, Turner syndrome is a condition that occurs when the individual inherits only one (female) X chromosome.

BigorU [14]

In many plants, stomata are found only on the lower surface of the leaf. The most likely explanation for this fact is that water loss would be less on the shaded lower surface than in direct sun.

Hypersecretion of growth hormone after long bone growth has ended (as an adult) is called

Anastasy [175]

The answer is the gigantism. A gigantism is a condition in which the growth hormone of an individual will likely be in excess than of its normal range and the reason for that is because of the pituitary tumor cells as they secrete the GH.
