Which of the following is/are TRUE about a cell’s plasma membrane? (CHOOSE ALL THAT APPLY.)
Question 3 options:
Plant cells have a cell wall instead of a plasma membrane.
Proteins are embedded in the plasma membrane and contribute to its function.
The exterior of a phospholipid bilayer is hydrophilic, and the interior is hydrophobic (see figure above).
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Answers
Answer:
The plasma membrane regulates the movement of molecules and ions into and out of the cell.
Explanation:
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. Both types of membranes have a specialized structure that facilitates their gatekeeping function.
The true statement about a cell’s plasma membrane is that the plasma membrane regulates the movement of molecules and ions into and out of the cell. The correct option is D.
What is a plasma membrane?The plasma membrane or cell membrane is the outer covering of the cell. It is made up of lipids and proteins. Cell membranes serve to separate and group cells. Every cell has an exterior plasma membrane that controls both what and how much of any given material enters the cell.
Eukaryotic cells, unlike prokaryotes, have internal membranes that enclose their organelles and regulate the exchange of vital cell components. Both kinds of membranes have a unique structure that makes it easier for them to perform the gatekeeping job.
Thus, the correct option is D. The plasma membrane regulates the movement of molecules and ions into and out of the cell.

Is water wet? Is the earth flat?
Answers
Answer:
1. Water isn't wet by itself, but it makes other materials wet when it sticks to the surface of them.
2. No, the Earth is roughly a sphere.
Explanation:
Brainliest?
Answer and Explanation:
1. Water is wet. This is because the water molecules cover each other and come in contact, making them wet. A water molecule by itself with no other molecules is not wet.
2. The Earth is NOT flat. This is because during lunar eclipses (when the Earth’s orbit places it directly between the Sun and the Moon, creating a shadow in the process), the shadow on the Moon’s surface is round. This shadow is the planet’s, which means that the Earth is spherical.

3. In 3-5 sentences explain why the saying,”you are what you eat” is factually correct
Answers
Answer:
The food we eat become nutrients and support the functions of our bodies. Our bones, cells, skin, hair, are all affected by the foods we eat. The nutrients in our foods become the main source of our bodies needs.
Explanation:
I hope that this helps you!
The rate of photosynthesis and cellular respiration can be measured by estimating the quantity of oxygen that is released and consumed as a product and reactant respectively.
What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
If a substance is dissolved in water it leads to a reduction in the surrounding temperature, this process is known as endothermic. This is because endothermic reactions consume energy through the surrounding atmosphere.
The statement "you are what you eat" is factually correct because the role of diet and the food that we eat directly reflects our appearance. As healthy the food we eat, the more healthy we become. The eating pattern and diet significantly relate to the overall health and fitness of an individual.
Therefore, all three questions are briefly described one by one.

A trait is marked by the tendency to act, think, and feel in a certain way—over time and across situations. Terms such as disposition, construct, dimension, and personality variable have very similar meanings and psychologists often use them interchangeably.
A trait can be thought of as a relatively stable characteristic that causes individuals to behave in certain ways. The trait approach to personality is one of the major theoretical areas in the study of personality. The trait theory suggests that individual personalities are composed of these broad dispositions.
