Answer:
B.
Explanation:
potential energy changes into kinetic energy
An insect with coloration to prevent from being detected by a predator would be an example of Camouflage.
<h3>What is the importance of Camouflage?</h3>
Camouflage, commonly characterized as cryptic coloring, is a defensive tactic used by organisms to obscure their appearance, generally in order to blend in with their environment.
Camouflage is utilized by organisms to hide their location, identity, and movement. This enables prey to evade predators while also allowing predators to sneak up on victims.
An insect with coloration to avoid being detected by a predator would be an example of Camouflage.
Thus, the correct answer is Camouflage.

Answer:
<em><u>D. Cytoskeleton</u></em>
Explanation:
It is really none of these answers. The correct answer would be a microtubule which is a component of the cytoskeleton which is in the cytoplasm.
The Cell Walls are only in plant cells so that won't work. So, A wouldn't work.
Chromosomes are the things that both your parents give you as genes. They have nothing to do with keeping the structure of the cell alright.
Cytoplasm cannot be a answer choice because, the thing is in it but, it doesn't do anything with it. So C wouldn't work either
The correct answer is microtubule however, it is a component of cytoskeleton so therefore, that is your answer.
<em><u>Reference the picture below:</u></em>
Glycolysis requires an investment of 2 ATP, but it yields a total of 4 ATP, netting 2 ATP. So more ATP is produced than is used.
Answer:
The correct answers are option A. "tethering proteins to the cell cortex", B. "using barriers such as tight junctions", C. "tethering proteins to the extracellular matrix", D. "forming a covalent linkage with membrane lipids", E. "tethering proteins to the surface of another cell"
Explanation:
According to the fluid-mosaic model, the components of cell membranes are in constant movement forming a barrier to avoid unwanted exterior component internalization and to avoid the loss of precious internal components. This constant movement could cause that proteins move across the plasma membrane. But, this is avoided by several mechanisms including:
A. Tethering proteins to the cell cortex. The cell cortex is a rigid structure made of actin and actomyosin. Proteins found in the plasma membrane are tethered to this structure to restrict their movement.
B. Using barriers such as tight junctions. Tight junctions are barriers found in epithelia made of claudin and occludin proteins. These barriers are impenetrable, which avoid the movement of proteins in the cell membrane.
C. Tethering proteins to the extracellular matrix. The extracellular matrix is made of several proteins and macromolecules that provide a structural and biochemical support to cells that are nearby. Proteins could be tethered to this rigid structure as well.
D. Forming a covalent linkage with membrane lipids. The proteins in the cell membrane that form a covalent linkage with membrane lipids are known as lipid-anchored proteins, or lipid-linked proteins.
E. Tethering proteins to the surface of another cell. When cell-cell communication take place it is possible that proteins in the cell membrane got tethered to the surface of the other cell.
