Which of the following is NOT true of mechanical digestion? Muscular contraction in the stomach mix food The teeth and tongue break food into smaller pieces It starts in the mouth Enzymes break down food
It starts in the mouth Enzymes break down food
Mechanical digestion is a type of digestion which is done by breaking of food materials into small pieces through physical means such as cutting and crushing by teeth and muscular contraction of stomach while the break down of food molecules by the action of enzyme such as saliva etc is chemical digestion. Chemical digestion helps in speeding up the process of digestion.
D. Enzymes break down food.
Mechanical digestion is the physical breaking down of food that starts in the mouth by chewing. Enzymes would be part of the chemical digestion.

the correct answer is a
In algae, cyanobacteria, and plants, chlorophyll a absorbs all colors of light except for A) red. Eliminate
Chlorophyll is found in and around the photosystems embedded in the thylakoid membrane of the chloroplasts.
The chloroplasts are organelles found in eukaryotic algae. The chloroplasts in eukaryotic celss are contained in the cytoplasm together with other organelles.
Since the chlorophyll is insided the chloroplast which is inside the cytoplasm, it is safe to say that the chlorophyll of the green algae is spread throughout the cytoplasm of its cells.

What type of molecules is used to store and release energy like a battery?
ATP molecules is used to store and release energy like battery.
The principle chemical compound that cell uses to store and release energy is Adenosine triphosphate or ATP.
living things use chemical fuels as well, one of the principal chemical compounds that cells use to store and release energy is adenosine triphosphate ATP.
Three main parts:
ATP consists of
adrenine, a 5-carbon sugar called ribose and three phosphate groups.
