Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small.
explicación:
The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. ... That is why cells are so small.
Cells are small to have a high surface-to-volume ratio and efficient exchange of materials with their environment.
All cells are very small because they need to have a high surface-to-volume ratio. The surface area of a cell determines the amount of substances that can enter or leave the cell, while the volume of the cell determines the amount of metabolic activity that can occur. By being small, cells can efficiently exchange materials with their environment and carry out essential functions.
For example, red blood cells are small to pass through the narrowest capillaries and transport oxygen to different parts of the body. Bacteria are also small to facilitate their nutrientuptake and waste removal.
Furthermore, the small size of cells allows them to have a faster rate of diffusion, which is important for the exchange of gases, nutrients, and waste products across the cell membrane.

Answer:
Chitin
Explanation:
Chitin is a natural biopolymer that is made of the N-acetylglucosamine, modified glucose.
Chitin is an important polymer mainly for the fungi and the arthropod insects as it is present in the cell wall of the fungi and the exoskeleton of the insects.
The chitin provides a protective function to this organism that the digestive enzymes cannot degrade this chitin but only the symbiotic bacteria can digest eat therefore they are sometimes avoided to be eaten.
Thus, chitin is the correct answer.
Answer:
The DNA fingerprinting is the correct answer I took the quiz
Explanation:
b. a base.
c. water.
d. a suspension
A substance with a pH of 6 is categorized as an acid. While it's close to neutral (pH 7), anything less than 7 is considered an acid in the field of chemistry.
In the context of chemistry, the substance you're referring to, with a pH of 6, is considered an acid. The pH scale runs from 0 to 14; substances with a pH less than 7 are classified as acids, substances with a pH greater than 7 are termed as bases, and a pH of 7 is neutral, represented typically by pure water. Even though a pH of 6 is close to neutral, since it's less than 7, it still falls under the category of an acid.

Answer: A. Julie loves chicken noodle soup, but her cold is making it taste bland.
Sensory interaction is the interaction among various sense organs of the body. It depicts how one sense organ influence the response from other sense organ. Taste and smell are examples of senses which are dependent on each other and can influence the response generated by external stimuli. For example, food tastes are bland when a person is not able to inhale it's smell. Julie loves chicken noodle soup, but her cold is making it taste bland. Here, the taste of noodle depends upon smell of food as, Julie is not able to inhale the smell of food therefore, the taste is bland. Hence, this illustrates the best example for sensory interaction.
