Fruit comes from many different places it can grow on plants, just like apples grow on trees and it depends on what kind of fruit because some can grow of flowers like strawberries, figs, raspberries, and many more.

I believe it would be something called the Ovules because this is a type of tissue in a plant that would help reproduce as humans do. Let me know if that helped.

We are pretending that I am testing to see if Vitamin C cures ashy skin. You must write out EVERY step of the study that I must

denpristay [2]

Answer: Independent variable is the Vitamin C and the ashy skin is the dependent variable.

Explanation:

We can change or manipulate the independent variable of the reaction and such change can be observed on the dependent variable. The dependent variable yields the results of the experiment and changes in the dependent variable must be observed attentively to frame the results.

Here, vitamin C is the independent variable whose affect has to be observed on the ashy skin which is the dependent variable of the experiment. Steps of the experiment:

1. We can apply Vitamin C in a form of solution on the ashy skin.

2. Observe the changes on the skin directly and apply for 2-3 times in a day.

3. Observe the changes on the skin after a week.

Which specific process in the light dependent reactions produce oxygen and hydrogen ions? A- The formation of NADPH

garri49 [273]

Light-dependent reactions involve a series of events that involve electrons moving along the transporter chain. Water provides the electrons, releasing oxygen and hydrogen ions. C) The splitting of water

<h3>What are the light-dependent reactions?</h3>

Photosynthesis involves two stages: light-dependent and light-independent reactions.

Light-dependent reactions occur in the thylakoids of chloroplasts. They Involve the noncyclic pathway which is a flow of electrons along a chain located in the thylakoid membrane.

Photosynthetic pigments are in charge of light absorption. When sunlight reaches the pigments, electrons provided by water get excited and move along the electron transport chain.

During these reactions, oxygen is released, while ATP and NADPH are produced. Both of them are used during light-independent reactions.

The steps of light-dependent reactions are the followings,

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

2) When the pigment molecules absorb light, electrons provided by water molecules get to 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) The absorbed luminous energy moves 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, it releases oxygen and hydrogen ions, which remain in the thylakoid lumen. From there hydrogen ions 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.

According to this information, the correct option is C- The splitting of water.

Water breaks down and releases oxygen, hydrogen ions, and provide electrons to the chain.
