how does the surface area to volume ratio affect the rate of diffusion
Answers
Explanation:
As the ratio gets smaller, it takes longer for items to diffuse.
Explanation:
When the cell increases in size, the volume increases faster than the surface area, because volume is cubed where surface area is squared.
When there is more volume and less surface area, diffusion takes longer and is less effective. This is because there is a greater area that needs to receive the substance being diffused, but less area for that substance to actually enter the cell.
this is actually why cells divide. When they become too large and it takes too long for them to transport materials across the cell, they lose efficiency and divide in half to raise the surface area to volume ratio.

If you have a cube-shaped with 6 sides and each sides 4 cm in length and width what will be the Surface area? Volume? Ratio of surface area to volume?
Answers
Answer:
The surface area will be 96 square centimeters(96cm^2), and the volume will be 64 cubic centimeters(64cm^3). The ratio is 3:2.
Explanation:
To find surface area, you find the area of one side of the cube, which is length x width. For a cube, the length and width are the same, so it was 4x4, which gives you 16, and then you multiply that by the number of sides, 6, to get 96.
To find volume, you multiply length x width x height, which are all 4cm for the cube.
To find the ratio, you compare the surface area to the volume similar to a fraction, except side by side. I simplified 96 and 64 by dividing them by 8, which gave me 12:8, and then I simplified that by 3 which gave me 3:2.

Answers
Answer:The option are not given, here are the options gotten from another website.
A. Aerobic respiration
B. Electron Transport Chain
C. Anaerobic respiration
D. Krebs cycle
The correct option is C.
Explanation:
This is because anaerobic respiration is a type of respiration that produced ATP. pyruvate are metabolize in the absence of oxygen by a process called fermentation and fermentation us anaerobic respiration. And fermentation is the chemical process where glucose or substrates are broken down in the absence of oxygen by the activities of enzymes. When pyruvate are metabolize in the absence of oxygen , it will produce lactate.
In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.
In biology, an incomplete oxidation process is called fermentation, which does not require oxygen to take place, and which produces an organic substance as a result.
Fermentation consists of a process of glycolysis (breakdown of the glucose molecule) that produces pyruvate (pyruvic acid).
As it lacks oxygen as a receptor for the excess electrons of the NADH produced (nicotin adenine dinucleotide), it uses an organic substance that must be reduced to reoxidize the NADH to NAD +, finally obtaining a derivative of the initial substrate that is oxidized.
In this process, then, neither the mitochondria nor the structures linked to the cellular respiration process are involved.Only 2 molecules of ATP are produced per molecule of glucose consumed.It is carried out by the muscle cells that ferment glucose when the oxygen input is not enough to continue breathing.Therefore, we can conclude that many cells also can metabolize pyruvate if oxygen is not present, via the process of fermentation.

Cancer is caused by abnormal growth is due to a genetic mutation. Which of the following can cause this genetic mutation? (Choose all that apply)
•Can be inherited
•Acquired with age after many rounds of cell division
•Caused by exposure to radiation
•Acquired from contact with a person who has cancer
Answers
Answer: Can be inherited, acquired with age after many rounds of cell division, caused by exposure to radiation
⬇ Explanation(s): ⬇
Exposure to Radiation: Exposure to very high levels of radiation, such as being close to an atomic blast, can cause acute health effects such as skin burns and acute radiation syndrome (“radiation sickness"). It can also result in long-term health effects such as cancer and cardiovascular disease.
Cell Division: Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. ... During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.

Cancer is the abnormal growth of the cells and can be due to genetic mutation. These mutations can be caused by inheritance, exposure to radiation, and age. Thus, options a, b, and c are correct.
What is the cause of cancer?Cancer is a disease where the cells have lost the ability to stop cell division resulting in the accumulation and uncontrolled growth leading to tumors. Cancers are caused by genetic mutations.
The mutations can be inherited if they are in the germinal cells and can be passed to the offspring. The radiations like exposure to UV can alter the DNA sequence as they are mutagens.
It can also be caused due to the increase in age as the cell division is affected by age and the mechanism may fail or mutate resulting in uncontrolled cell growth.
Therefore, options a. inheritance, b. acquired with age, and c. exposure to radiation is the cause of genetic mutation.
