Answer:
Actin filaments return to their original positions (does not occur in muscle contraction, according to the sliding filament model).
Explanation:
Turtles
Reducing the amount of artificial light that is visible from nesting beaches is the first step to reducing light pollution that affects sea turtles.
Snakes
when snakes are in the sunlight they can gain alot of energy and heat and they can stay warm for a long time.
I dont realy know about the other two
<u>Answer</u>:
Neutral molecules are the products of the hydrolysis reaction.
<u>Explanation</u>:
Hydrolysis reactions are double decomposition reactions. In these reactions water reacts to the ester linkage in a molecule resulting into the breaking of bond between the elements of the molecules.
The products those result include the one which receives the hydroxyl (OH) group from the reacting water molecule and another one receives the remaining proton (H+). For example, if AB is a compound in which A and B are atoms or groups after the hydrolysis reaction with a water molecule (HOH) the products of this reaction may be the neutral molecules represented by the given reversible chemical equation i.e. AB + HOH ⇌ AH + BOH.
D: a nucleus
the prokaryote cell has no nucleus and for that matter no other membrane bound organelle
NADH and FADH2 are necessities in the electron transport chain because they power the chain by moving electrons into it.
NADH and FADH2 are both generated at the initial stages of respiration (the Kreb's cycle), a process during which food materials are broken down to generate energy. NADH is generated from NAD+ as a result of the addition of electrons while FADH2 is generated from FAD also due to the addition of electrons.
Once generated, both compounds get transferred into the innermost membrane of the mitochondrion where they travel down the electron transport chain, donating their electrons in the process and creating an electrochemical gradient to generate ATP.
Without NADH and FADH2, there will not be electrons to power the electron transport chain and the generation of ATP would become impossible.
