Answer:

This question is incomplete

Explanation:

This question is incomplete but the completed question can be seen in the document attached.

There are three main subatomic particles namely electrons, protons and neutrons. However, the question only discusses two of them; electrons (negatively charged) and protons (positively charged).

A. Found in all matter

Answer: They are <u>both</u> found in all matter since all matter are made up of atoms and all atoms have both protons and electrons (and even neutrons).

B. Negative charge

Answer: The subatomic particle with negative charge (as discovered by R.A Millikan) is the <u>electron</u>

C. Exists in the nucleus

The subatomic particles found in the nucleus are the <u>protons</u> and neutrons.

D. Attract opposite charges

They <u>both</u> (protons and electrons) attract opposite charges because they are of opposite charges and generally unlike charges attract.

E. Moves at extreme speed

Of the two subatomic particles mentioned, <u>electrons</u> move faster than protons because of there lighter mass when compared to the protons. However, the fastest subatomic particle is the neutrino.

F. Bound by strong force

The <u>protons</u> are bound by strong nuclear force which binds them to the nucleus of the atom.

Explain the processes that take place in the stroma including the reactants going in and the products produced from these proces
poizon [28]

Stroma, in a biological explanation, the fluid in between grana, where carbohydrate formation reactions occur in the chloroplast of plant cells photosynthesizing.

Explanation:

Part A

 In the bright daylight, the Calvin cycle happens indoors in the stroma. throughout the Calvin cycle, the results  ATP and NADPH are conventional convert molecules of carbonic acid gas into high-energy sugars.

Part B

In the darkness, the Calvin cycle conjointly occurs within the stroma. through the Calvin cycle, the products ATP and NADPH are used to change molecules of CO2 into high-energy sugars.

Part C

There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be sustained.
