Elden [556K]

Answer:

C

Explanation:

For the first blank, we need to find a word whose definition is essentially "to conceive of another's emotional state", and for the second blank, we need to find a word whose definition is "allows you to see a situation from another viewpoint".

Let's define all the words given:

- "perspective": one's way of viewing something - basically, your viewpoint of a certain issue

- "empathy": being able to understand another's emotions

- "understanding": comprehending another's situation or the issue at hand

- "trust": the assurance that you can rely on a person when you're in need

Out of all these, only "empathy" fits the first blank and only "perspective" fits the second. So, C is correct.

Which of the following is an example of a closed system?
Yakvenalex [24]

Answer: B

Explanation: A closed system can be defined as a system that does not allow for an exchange of matter with its surroundings.

An estuary where fresh water and ocean water mix is not a good example of a closed system because fresh water and ocean water mix out in the open and matter is exchanged.

A living single-called organism such as phytoplankton does not constitute as a closed system because in order for the phytoplankton to be considered alive it needs to interact with its surroundings i.e light from the sun so photosynthesis (converting light energy into chemical energy to be used by organism) can occur. This also happens out in the open

A river that flows into the ocean does not fit into the closed system definition. This is because a river that flows into the ocean allows for itself (matter) to mix with that of the ocean in an open space (rivermouth).

Therefore option B is the answer because it fits the definition. A chemical reaction within the deep ocean organisms that allows them to glow happens within (inside) the organism, making this system closed, hence there is no exchange of matter with surroundings.

Why does water have unique characteristics compared to other similar
maksim [4K]

Answer:

A. Water molecules have strong intermolecular attractions.

Explanation:

Water molecules have strong intermolecular attractions due to the presence of hydrogen bond between oxygen and hydrogen atoms. This hydrogen bond is present between hydrogen of one water molecule to the oxygen of another water molecule. This hydrogen bond is weaker than covalent bond so that's why it can be broken down and water is converted into vapours form by heating.
