Bacteria are able to sense and respond to a variety of external stimuli, with responses that vary from stimuli to stimuli and from species to species. The best-understood is chemotaxis in the model organism Escherichia coli, where the dynamics and the structure of the underlying pathway are well characterised. So YES they are able too hope this helps

When humans taste or smell, receptors unique to each nerve cell detect the chemical and send signals to the brain, where many cells process the message to understand what we are smelling or tasting. But a bacterium is just a single cell, and it must use many different receptors to sense and interpret everything around it.

Answer:

the answer would be A

Explanation:

Animal cells are oval and egg shaped so we can cancel out c and d

A is the correct answer because we can see green dots within the structure. Chloroplasts contain a green pigment called chlorophyll. This green pigment makes the chloroplast and the structure green (as we can see in the picture). Photosynthesis occurs in the chloroplasts, and it is where the plant gets its glucose from

The splitting apart of two organic molecules in a polymer and adding back the water parts to make individual monomers again is c

Pani-rosa [81]

The process of dissolving two organic molecules in a polymer and recombining the water molecules to create new monomers is known as hydrolysis.

<h3>What is hydrolysis?</h3>

The molecule is broken in a hydrolysis reaction involving an ester bond, such as the one between two amino acids in a protein. As a result, the water molecule (H₂O) splits into two groups: one that forms a hydroxyl (OH) group with the remaining hydrogen proton (H+) and another that transforms into a carboxylic acid.

Practically speaking, hydrolysis refers to the process of separating compounds when water is present.

Condensation, which is the process by which two molecules combine to produce one bigger molecule, can also be thought of as the opposite reaction to hydrolysis. The outcome of this reaction is that a water molecule is ejected by the larger molecule.

The three primary hydrolysis processes are

Salt hydrolysis.

Acid hydrolysis.
Base hydrolysis.

You are an experienced naturalist and biologist and you observe two birds mating that you do not believe are members of the same

Answer:

B) Post-zygotic factors prevented successful reproduction.

Explanation:

Postzygotic factors may influence the formation of the fertile offspring.

The postzygotic barriers basically involves the formation of the hybrid organisms which do not survive past the embryonic stages i-e hybrid inviability / the hybrid creation that is unable to form the offspring i-e sterile.

So , in the given scenario option B )Post-zygotic factors prevented successful reproduction is the right answer .
