The choices can be found elsewhere and as follows:

<span>Osmosis
Active Transport
Passive Transport
Facilitated Diffusion

I think the correct answer is the second option. The process that would be necessary is active transport. </span><span>Transport of materials against the concentration gradient requires energy which is active transport.</span>

The right answer is active transport.

Active transport is the process of moving molecules across a cell membrane through the use of cellular energy.

The alternative to active transportation is passive transport, which uses kinetic energy to relocate only the molecules. Passive transport can only move molecules from a region of higher concentration to lower concentration, while active transport moves molecules from a lower concentration site to a higher concentration. Active transport involves molecules moving against a concentration gradient of the molecule concerned.

Georgia [21]

Answer:

The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, vitamins green spinach, Fat and oil or lipids from sunflower seeds, proteins...

The Carbohydrates is processed into glucose, proteins is processed into amino acids, lipids is processed into fatty acids and glycerol.

Explanation:

From the food consumed, The biology Molecules that will.be present in what she consumed are Carbohydrates from unbuttered bread, green spinach contains vitamins like vitamin K, vitamin A, vitamin C, vitamin B12 , minerals like magnesium, iron, Fat and oil or lipids from sunflower seeds, proteins...

The Carbohydrates is processed into glucose after enzymes like salivary amylase acts on it from the chewing and in the stomach which produces glucose which makes it easily absorbable , proteins is processed into amino acids by the activity of hydrochloric acids and protease that processed it into amino acids, lipids is processed into fatty acids and glycerol by the activities of the enzymes lipase.

The minerals and vitamins present are in a way they can be absorbed.

Which energy source did you rank as the worst option for the rescue team
stellarik [79]

Answer:

The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.

Explanation:

The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry  anywhere.

Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.

Thus, the worst option are-  nuclear, hydroelectric, combustion and fuel burning energy source.

Which attributes would allow a cell to be larger?
Leno4ka [110]

Answer:

Perfectly cube - shaped

Explanation:

If the shape of a cell is perfectly cube- shape then its volume must be calculated with an equation:

Height×Width×number of sides and number of boxes

Surface= area of volume ratio is calculated with an equation

Area /volume

if a cell has large surface area to volume into ratio means it has greater exposure to the environment.It means that flow of nutrients and gases move freely in the small cell compared to large cell.
