What are Proteins?</h3>
The body uses the large, complex molecules called proteins for a number of essential processes. They perform the majority of their work inside cells and are essential for the development, functionality, and regulation of the body's tissues and organs.
Proteins are made up of countless thousands of amino acids, which are the smallest units that make up proteins. Twenty different types of amino acids can be combined to form proteins. The arrangement of the amino acids determines the precise function and characteristic 3-dimensional structure of each protein. The order of genes determines the combinations of three DNA building blocks (nucleotides) that code for amino acids.

Answer:
<h2>C. placing carrier proteins in the membrane.</h2>
Explanation:
If there is no barrier preventing molecules from moving molecules, then there will be large movement of molecules from an area of high concentration to an area of low concentration. This passive process is known as diffusion. The phospholipid bilayer of a cell's membrane works as a barrier to large molecules, ions, and most hydrophilic molecules. Whereas small hydrophobic molecules can pass freely through the phospholipid bilayer, other molecules and ions are transported across the cell membrane with the help of transport proteins. Some transport proteins, allowing hydrophilic molecules and ions to passively move through them and across the cell membrane.
Examples: carrier proteins and channel proteins.
Placing carrier proteins in the cell membrane will allow the molecule to reach equal concentrations on the both the sides of the membrane and maintain that way over long time. In contrast, transport proteins known as pumps will use cellular energy, usually in the form of ATP, to transport molecules.
Placing equal numbers of intracellularly directed and extracellularly directed pumps would also equalize the concentrations of a molecule long over time. Pumps are to transport molecules against their concentration gradient, such as the sodium-potassium pump continuously moves sodium ions out of a cell.
Through the use of carrier proteins, there is equalization of concentrations of a hydrophilic molecule. This equalize the numbers of molecules on the inside and outside of the cell, but the pumps would continue moving the molecule inward, eventually resulting in more molecules inside of the cell than out.
Answer: B. The number of individuals that a habitat can sustain with the resources that it has available.
Explanation:
A carrying capacity is the number of individuals of the population belonging to a particular species that an habitat or region or ecosystem can support or sustain in terms of providing the resources. If the population exceeds over the carrying capacity then this results in decline in members of the population.
According to the above description the accurate definition of carrying capacity is B.
It is C because when two species benefit from each other it is called mutualism
Compared to benign tumors, malignant tumors are different because the cells in malignant tumors are cancerous.
