The diagram represents part of a plant cell. Identify the name of the location in the plant cell
konstantin123 [22]

Answer:

The <u>stroma</u> within the chloroplast

<u />

Explanation:

Chloroplasts are membrane-bound organelles  in plants. They comprise many invaginations of a plasma membrane called a thykaloid membrane. This includes chlorophyll pigments in layers called granum, whereas the internal spaces of the organelle are called lumens. Fluid surrounds the granum, and forms the stroma; here, all metabolic reactions within the chloroplast occur- <u>including CO2 fixation.</u>

Photosynthesis, involves the conversion of energy from photons or light particles and water, starting in the thykaloids; here, the pigments like chlorophyll, which is essential to photosynthesis, reside.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy= glucose + oxygen

Ierofanga [76]

<u>Answer: </u>

When the outer electron shell is full in an element, this creates a Noble gas.

<u>Explanation</u>:

Noble gases are the elements that belong to group 18 in the periodic table.  Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.

There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.

Jill stepped on a tack. Which part of the central nervous system caused her foot to move off the tack quickly in a reflex respon
Veseljchak [2.6K]

Answer: Spinal cord.

Explanation:

The spinal cord of the central nervous system helps to move off quickly as a part of the reflex response. Jill stepped on a tack and suddenly he realizes that he should quickly move his legs out of the tack.

The pain is not stimulated until the signals reaches from the receptor to the brain. The formation of the reflex arc ensures that the amount of potential tissue damaged is less.

It forces the body to move quickly from the place that is causing damage.Example: Moving the leg up involuntarily when stepped on pin.

This occurs because the sensory neurons connects to the motor neurons within the spinal cord.This leads to the contraction of bones and muscles.

Hence, the correct option is spinal cord.

An egg is protected by its outer shell. However, the shell also allows moisture and air to pass through. Which cell structure pe
ElenaW [278]
A cell membrane would most likely be close to an egg structure. A cell membrane is a selective permeable to ions and organic molecules and controls the movement of substances in and out of the cell. 

The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the lipid bilayer with embedded proteins.
