The answer is “common ancestry”

andre [41]3 years ago
3 0

Answer:

The correct answer is option 2. Common ancestry.

Explanation:

The homologous structure is the structure that has a similar anatomical structure or underlying skeleton and can perform a different function in different organisms.

Homologous structures are similar in different organisms because they diverge from a common ancestor. All organisms that have homologous structures are considered to have a common ancestry. for example, human arm, dogs forearm, bat's wing all have a similar skeleton structure  

Thus, the correct answer is option 2. Common ancestry.

pychu [463]

Answer:

C.

Explanation:

Homeostasis refers to the tendency for the human body to attempt to maintain a certain state even during changes in environment, activity, intake, etc. Options A, B, and D all refer to instances where the body departs from its usual state. While the scenario in Option C does describe a change in environment, it also describes the reaction of the body that brings its internal systems back to a certain state of fluid level.

juin [17]

Answer:

This question lacks options, options are:

a) indirect

b) mosaic

c) determinative

d) regulative

e) direct.  

The correct answer is d.

Explanation:

The egg (ovum) like the embryo during the first embryonic divisions, do not possess any sign of polarity. This development mechanism can be called regulative development(in contrast to the mosaic model) since the fate of the cells that originate is not fixed and can be modified during development. In regulative embryos, part of the embryo can be removed and the remaining cells can compensate for the loss and give a complete individual as the final product.The strongest evidence that continues to support this regulatory model is based on the plasticity or potential that mammalian cells possess before implantation. It is known that the blastomeres produced by the first divisions can be replaced with each other or even can be eliminated without apparently altering the embryonic development and therefore they are equivalent (without polarity).

Chloramphenicol binds in the active site of the large ribosomal subunit and inhibits peptidyl transferase activity in the 23s rr
valentina_108 [34]
This inhibition is restricted to bacterial translation because; the peptidyl transferase is an enzyme aminoacyltransferase as well as the primary enzymatic function of the ribosome, which forms peptide bonds between adjacent amino acids using tRNAs during the process of translation. Therefore, inhibition of this enzyme means that the process oof translation wont take place, hence proteins will not be formed and thus the bacteria will die.
