Which statement describes one feature of Rutherford’s model of the atom? The atom is mostly empty space. The atom cannot be divi
Dovator [93]

Answer: The atom is mostly empty space.

Explanation:

Before to Rutherford, the accepted model for the atom was Thomson's model:

The atoms were a positive sphere, with electrons occupying space in it".

This was called the "plum pudding model".

Then came Ernest Rutherford, and he created a model where the atoms are mostly empty space (void) with a positive charged nucleus (really compressed in the center), and the electrons were orbiting around it.

Then the correct option is that the atom is mostly empty space.

A table with four organisms and their primary role in an ecosystem is shown.
Otrada [13]

Answer:Each and every one of us have several roles. Organisms in a community play other roles too. An organism's role within an ecosystem depends on how it earn its nutrients. Organisms collect their nutrients in very different actions, so they have different roles in an ecosystem.

Explanation:  

The food chain describes who eats whom in the wild. Every living thing—from one-celled algae to giant blue whales—needs food to survive. Each food chain is a possible pathway that energy and nutrients can follow through the ecosystem.

For example, grass produces its own food from sunlight. A rabbit eats the grass. A fox eats the rabbit. When the fox dies, bacteria break down its body, returning it to the soil where it provides nutrients for plants like grass.

Of course, many different animals eat grass, and rabbits can eat other plants besides grass. Foxes, in turn, can eat many types of animals and plants. Each of these living things can be a part of multiple food chains. All of the interconnected and overlapping food chains in an ecosystem make up a food web.

Functions of astrocytes include all of the following except
Neporo4naja [7]

The question is incomplete. The complete question is as follows:

Functions of astrocytes include all of the following, except

A) performing repairs in damaged neural tissue.

B) guiding neuron development.

C) functioning in action potential transmission.

D) maintaining the blood-brain barrier.

E) creating a three-dimensional framework for the CNS.

Answer:

Functioning in action potential transmission.

Explanation:

Astrocytes may be defined as the glial type star shaped cells present in the central nervous system. They envelope the synapse and can function with millions of neuron at a time.

Astrocytes are involved in the structural support in the brain and can repair the damaged and wear nerves tissue. Their main function is acting as blood brain barrier. The action potential transmission is mainly done by neurons and not by the astrocytes cells.

Thus, the correct answer is option (c).
