Why is the model used to describe the plasma membrane called the fluid mosaic model?

Answers

Answer 1

Answer:

Answer:

Because proteins and lipid tails are free to move and are not bonded by strong interactions with each other.

Explanation:

The plasma membranes have two layers of phospholipids in which proteins are present. The hydrophobic fatty acid tails of phospholipid layers make the inner core of the membranes. However, the tails are not bonded to each other and make a fluid-like base in which proteins are present. Also, the membrane proteins are not bonded to the phospholipids and are free to change their position within the phospholipid leaflets. This is why the model is described as a fluid mosaic model.

Explanation:

Corals are found in shallow water because they need access to:a. algae
b. sunlight
c. plankton
d. fish

Answers

Correct answer: B). Sunlight

Corals are found near the shallow water because it needs clear water that allows the sunlight to pass through it, they are not able to survive in when the water becomes opaque.

Presence of plankton and sediment can cloud the water, which decreases the amount of sunlight that reaches the corals. Corals are found in tropical and subtropical water.

In an experiment, the hypothesis is If the wavelength of the light shining on a plant is shortened, the rate of photosynthesis is slowed down. If this experiment is performed, the dependent variable?

Answers

The variables are the factors, which do not have a fixed value. Their value keeps changing in an experiment. It can be divided in two types: dependent variable and independent variable.

The dependent variable in the experiment is the variable, whose tendency to vary depend on other factors. To test this hypothesis, the rate of photosynthesis with respect to different wavelengths. So, the dependent variable is rate of photosynthesis, as it is dependent on the wavelength of the light.

The dependent variable is the part of the experiment that depends on the other part, the independent part. The dependent variable would be the plant because it's growth depends on the light wavelength.

Which of the following makes the statement FALSE? In the alternation of generations life cycle, the generations that alternate A. Are haploid and diploid multicellular organisms B. Produce each other C. Directly develop into one another as parts of the same individual D. May be physically attached

Answers

Answer:

The false statement is option C. Directly develop into one another as parts of the same individual.

Explanation:

Alternation of generations is one of the type of the life cycle which is common in land plants and some of the alga species change n between haploid and diploid generation alternatively of an individual. It is presented in the plants only as in animals both haploid and diploid cell present in every generation.

In the alternation of generation, generation does not directly develop into each other as part of the particular individual.

Thus, the correct answer is option C. Directly develop into one another as parts of the same individual.
