sighs, well i guess older kids dont get technology as much as we do.
no offense, but seriously if you pay more attention in class you might not be asking this silly question right now.
Molecule which enzyme<span> acts on = the substrate. 5. Substrate molecule is held within the active site by bonds that temporarily form between certain amino acids of the active site and groups on the substrate molecule. ... This folds in a particular way = each </span>enzyme<span> has a </span>specific<span> tertiary </span>structure<span>.</span>

DNA determines the fate of each cell.
DNA is the basic genetic unit for each cell and contains information about the fate of the cell. The DNA of daughter cell which remains in stem cell state and continues to divide causes production of those substances which promote it to stay in stem cell state and also promote its continuous division. On the other hand, the DNA of specialized cell causes production of substances which changes characteristics of the cell and causes it to become a mature and specialized cell.

Explanation:
1 - Habitants
From this term, it is understood that a habitant is someone or something that inhabits a habitat and lives there, in a sense.

3 - Population
A population is the number of organisms in a species or total amount of something/someone in an ecosystem or community.
4 - Food Chain
A food chain represents a chain of how and where food flows within a small ecosystem or community. For instance, a basic food chain can be like this: Sun - Grass - Cow - Human - Decomposers
5 - Food Web
A food web is comprised of multiple food chains and animals/organisms. It depicts how and where energy travels in a more vast manner compared to a food chain.
Hope this helps!
Answer:
c. Osmosis is the diffusion of water molecules across a selectively permeable membrane.
Explanation:
Osmosis is the passive transport of water molecules from the region of their higher concentration to that of lower concentration through a semi-permeable membrane. Osmosis does not include the movement of solutes. When two solutions with different concentrations of solutes are separated by a semi-permeable membrane, water moves through the membrane from a hypotonic solution to the hypertonic solution until equilibrium is obtained. This process is called osmosis.
Most chemical digestion and absorption of nutrients takes place in the _small intestine_.
All macronutrient (protein, carbohydrate, fat) breakdown into their basic subunits (monomers) is finalized in the small intestine. This is where all foodstuffs will meet the last set of enzymes and emolients/emulsifiers (dissolvers) to do the final breaking of bonds (chemical digestion). And it is therefore also in the small intestine that a vast blood supply allows a special circulatory route to absorb (pick up) these nutrients (sugars, amino acids, small fatty acids) via their tiny capillaries, and transport them to the liver for processing. This circuit is known as the Portal Venous System.
