Answer:

Botulism toxin disrupts motor control <u>by blocking the release of acetylcholine by motor neurons.   </u>

Explanation:

Acetylcholine is the principal neurotransmitter in motor neurons. If there is no release of acetylcholine from the presynaptic motor neuron, the ion channels will not open. If the ion channels do not open, Na+ cannot enter the postsynaptic membrane to start an action potential. As a result, the muscle can not move.

The ion channels have a specif receptor for acetylcholine. When acetylcholine binds to the receptors, the channels open. With the ion channels open, Na+ can enter the postsynaptic membrane to start an action potential. This does not happen in the presence of botulism toxin since it blocks the release of acetylcholine.

One reason why small patches of protected land could be disadvantageous is ____.
Veseljchak [2.6K]

C. It would make it for difficult for animals to move around and seek resources in other areas.

Explanation:

Small patches of protect land makes it difficult for animals to move around and see resources in other areas.

Protected areas or conservation areas are locations that receive special protection because of the natural diversity found in them.

  • Protected areas in some places are the last refuge for animals and plant species for safety.
  • The larger a protected area is, the better and more advanced an organisms niche can be.
  • A small protected area limits the niches of roaming animals and makes it difficult to seek for resources out of their limited scope.

Reactions between atoms occur when:
VikaD [51]

Answer; All the above

A) an atom seeks to fill its outer shell of electrons

B) an atom seeks to balance its positive and negative charges

C) the reaction will result in paired electrons

Explanation;

-In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

-During a chemical reaction an atom may lose of gain electrons resulting positive and negative ions (ionic bond formation) or may result to the paired electrons (sharing of electrons).

How does the increase in the predator population affect the environment? Connexus
tankabanditka [31]

Answer:

Increase

I cant remember the lesson number but if the number of predators increase it would make many animals that are there prey to become scarce in the area the predators are in wich would make many predators starve so in order to avoid they would have to move out across more land to find more food

if a cell increases the activity of its actin severing proteins, will it lead in the short term to more or less actin polymer ma
marta [7]

More polymer will form if the concentration of free actin monomers is higher than the Cc at both the plus and minus ends.

Less polymer will form if the concentration of free actin monomers is lower than the Cc at both the plus and minus ends.

Actin polymerization encourages FAK and Src to activate small G proteins by signalling to GEFs and GTPases (e.g., Rho and Rac). The actomyosin network is then forced to develop as a result of G proteins' induction of cytoskeleton-regulating proteins.

What stops cells from forming actin polymers?

Actin monomer is sequestered by monomer-binding proteins, reducing its availability for polymerization. As a result, actin does not polymerize when monomer-binding proteins are present in stoichiometric levels.

Q. If a cell increases the activity of its actin severing proteins, will it lead in the short term to MORE or LESS actin polymer mass? Chose the most accurate answer.

Increased severing activity will result in LESS polymer under any conditions.

Increased severing activity will result in NO CHANGE in the total amount of polymer under any conditions. It simply results in a larger number of smaller filaments.

Increased severing activity will result in MORE polymer under any conditions.

If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then LESS polymer will result.

If the concentration of free actin monomers is above the Cc for both the plus and minus ends, then MORE polymer will result. If the concentration of free actin monomers is below the Cc for both the plus and minus ends, then LESS polymer will result.

When disaccharide a is hydrolyzed which monosaccharide units are produced?
lina2011 [118]

Monosaccharides and disaccharides also called sugars. Have sweet taste, water-soluble. Disaccharide output of two monosaccharides are the same or different when hydrolyzed.  Monosaccharide a carbohydrate that can’t be hydrolyzed to simpler carbohydrate units.  Polysaccharides are extended polymers of monosaccharide units joined by O-glycosidic linkages. Energy storage.
