Biology

MAXImum [283]3 years ago
5 0

Answer:

Charge & Size

Explanation:

The smaller the particles, the easier they can diffuse through the cell membrane because they can pass through the channels of the cell membrane,

The lipid layer of the cell membrane  is hydrophobic hence‘hates’ charged molecules. Polar or charged molecules will need special channels with trans-membrane proteins to facilitate their movement

Drag the terms on the left to the appropriate blanks on the right to complete the sentences. resethelp biomass assimilated feces
yaroslaw [1]

1. The right answer is not assimilated

The assimilation designates in biology the process by which substances and materials external to the body are transformed into substances and materials interior to the body.

2.  The right answer is feces.

Feces correspond to the residue of digestion that the intestine could not absorb. They consist of 80% water and 20% dry matter (intestinal cell debris, bacteria, cellulose that comes from the non-absorbable part of plants).

3. The right answer is assimilated  

The opposite of the first one.

4. The right answer is cellular respiration.

Cellular respiration is the process of cellular metabolism that converts the chemical energy contained in nutrients into ATP (adenosine triphosphate).

5. The right answer is assimilated

"Assimilation" can be also used for energy.

6. The right answer is biomass

In the field of energy, biomass is the organic matter of plant origin (microalgae included), animal, bacterial or fungal (fungi), usable as a source of energy.

7. The right answer is biosynthesis.

Biosynthesis consists of a formation and production of a chemical compound body by a living organism, usually due to the catalysis of an enzyme. For example, protein synthesis is the synthesis of organic substances by an organism. Chemosynthesis and photosynthesis are biosynthesis.

8. The right answer is non assimilated.

Since it is lost, so it is not assimilated by the organism.

9. The right answer is biosynthesis.

In ecology, the trophic level is the rank occupied by a living being in a food web. It is measured in some way by the distance separating this being from the basic level which is that of the primary autotrophic production.

Above this basic level, each link (or stage) of a food chain corresponds to a trophic level.
