Answer:

Key points

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

Introduction

If you were a single-celled organism and you lived in a nutrient-rich place, staying alive would be pretty straightforward. For instance, if you were an amoeba living in a pond, you could absorb nutrients straight from your environment. The oxygen you would need for metabolism could diffuse in across your cell membrane, and carbon dioxide and other wastes could diffuse out. When the time came to reproduce, you could just divide yourself in two!

However, odds are you are not an amoeba—given that you're using Khan Academy right now—and things aren’t quite so simple for big, many-celled organisms like human beings. Your complex body has over 30 trillion cells, and most of those cells aren’t in direct contact with the external environment.^11start superscript, 1, end superscript A cell deep inside your body—in one of your bones, say, or in your liver—can’t get the nutrients or oxygen it needs directly from the environment.

How, then, does the body nourish its cells and keep itself running? Let's take a closer look at how the organization of your amazing body makes this possible.

I hope it helps you ✌

Aliyah is certain that she is the smartest person in her work place. She thinks she is clearly far more talented than everyone,
densk [106]

Answer:

Sense of grandiosity

Explanation:

In psychology, the term of "sense of grandiosity" is used to refer to a sense of superiority that an individual develops and makes them think that <u>they are better/superior than the rest of the people. </u>They see their peers as inferior  and they believe that only a few selected persons are at the same level as them.

In this question, Aliyah is certain that she is the smartest person in her workplace and she thinks her coworkers are less talented. However, this is a distortion since she actually has an average IQ and their coworkers don't perceive her as a particularly unique person. T<u>herefore this is an example of sense of grandiosity. </u>
