Answer:

1.   As the cell size increases, the ratio of surface area to volume DECREASES

2.   It depends on the unit of the ratio 6:1. If it is in cm−1, then it means that it is similar to a cell of size 1 cm^3,  which is normally too big to get materials from the surface .

3.  A Small cell has a large surface area/volume ratio and therefore can exchange molecules with it's external environment rapidly. So, Here cell with ratio 6:1 is smaller and have ability to better transportation across it's membrane as compared to other cell with ratio 3:1

 HOPE THIS HELPS!!!

How is light energy converted into chemical energy during photosinthesis?
qwelly [4]
Light energy (from the sun) is used to convert carbon dioxide and water into glucose and oxygen in the process of photosynthesis.
carbon dioxide + water --> glucose + oxygen
the light energy from the sun is then trapped in the glucose. in order to retrieve the chemical energy stores within the molecule, the bonds have to be broken.

KiRa [710]

a feedback mechanism that maintains homeostasis

Explanation:

Anhidorosis mostly directly interferes with a feedback mechanism that interferes directly with a feedback mechanism that maintains homeostasis.

Since anhidorosis is the inability to properly or normally sweat, it affects the process of homeostasis.

Homeostasis is an important characteristics of life.

It is the ability of organisms to maintain and sustain a balance environment within and outside of them.

Sweating is one such process by which the body carries out homeostasis. On a hot day, the body produces sweat which evaporates and release latent heat to cool the body. This inability affects the intricate balance between the environment and the body.

Are viruses living organisms
viva [34]

Answer:

No. Viruses are not living organisms.

Explanation:

Viruses are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living things.
