Morgarella [4.7K]

Answer:

you can see below

Explanation:

Basic Definitions:

Cell Membrane = the semi-permeable structure that surrounds the cell and keeps all of the cells organelles from exploding everywhere.

Cell Wall = the rigid 'armor' of the cell that surrounds it after the membrane. Usually made up of cellulose and ONLY found in plant cells.

Nucleus = A really dense organelle of the cell usually surrounded by two membranes. They contain and protect your genetic material. Basically everything that makes you, you.

Cytoplasm = The watery, salty, and protein filled 'soup' that fills the cell. All organelles float happily in this.

Now Specific Locations:

Eukaryotic cells

have plasma membranes

please mark me brainliest or mark me thanks at leat

only have cell walls if the cells are plants.

They do have a nucleus.

They have cytoplasm

Prokaryotic cells

have plasma membranes

cell walls are usually chemically complexed.

don't have a nucleus

have cytoplasm

Animal cells

only have the plasma membranes.

No cell wall

have a nucleus

have cytoplasm

Plant cells

have both the cell wall

and have a plasma membrane

have a nucleus

have cytoplasm

Sayyid drew a diagram to compare the gravitational and

Jlenok [28]

Gravitational: A.is attractive only

Electromagnetic: C.attracts and repels

Both: D.has an infinite range

Explanation:

The two forces mentioned in this problem are:

- Gravitational force: this force is the force that is exerted between any object with mass. The magnitude of the force is given by

$F=G\frac{m_1 m_2}{r^2}$

where

G is the gravitational constant

m1 and m2 are the masses of the two objects

r is the distance between the objects

This force is always attractive and it has an infinite range.

- Electromagnetic force: this is the force exerted between electrically charged objects. The magnitude of the force is given by

$F=k\frac{q_1 q_2}{r^2}$

where

k is the Coulomb's constant

q1 and q2 are the charges of the two objects

r is the distance between them

This force is attractive when the charges have opposite sign and repulsive when they have the same sign. It also has an infinite range.

Therefore, we can conclude that:

Gravitational: A.is attractive only

Electromagnetic: C.attracts and repels

Both: D.has an infinite range
