Answer:

c. A bacterial cell that lacked receptors on its surface for that antibiotic

Explanation:

If the bacteria lacks the receptors on its surface meant for that antibiotic then it will be best defense for the survival of that bacteria. It is receptors which interact with the antibiotic so as to permit it inside the cell. Therefore, in the absence of receptors, it doesn't matter how much antibiotic is lying in the external environment of that bacteria, the antibiotic will not be able to enter the bacterial cell to kill it. Hence, the bacteria will be able to survive easily.

Answer:

The correct answer is option c."A bacterial cell that lacked receptors on its surface for that antibiotic".

Explanation:

There are different mechanisms by which bacteria can get antibiotic resistance. One common mechanism is that the bacteria changes the site or changes the receptor that is recognized by the antibiotic to work. Taking into account this adaptation, a bacterial cell that lacked receptors on its surface for the antibiotic from the beginning would best be able to survive an attack by an antibiotic.

In many eukaryotic cells, DNA stored in the nucleus is transcribed into messenger RNA. The mRNA is then transported into the cyt

ki77a [65]

Answer:

The statement supported by the description of the process of protein synthesis determined by DNA and its packaging and sorted by the Golgi apparatus is that various organelles within a cell interact with each other to carry out life processes (option D).

Explanation:

From the transcription of RNA from DNA to protein synthesis and its packaging and distribution, the participation of organelles is observed:

Cell nucleus: contains the DNA and is where the transcription into mRNA occurs.
Ribosomes: where the mRNA is coupled to produce translation and protein synthesis.
Rough endoplasmic reticulum: contains ribosomes and participates in the process of membrane protein synthesis, also contributing to their conjugation, glycosylation or sulfonation.
Golgi apparatus: it is in charge of receiving synthesized proteins, packaging and distributing them to be sent to the extracellular space or other cells.

In this way, the coordination of the functions of various organelles is useful and necessary to fulfill vital functions. The statement that varoius organelles within the cell interact with each other to carry out life processes is, therefore, correct.

The options for this question are:

A. Organelles within a cell act independently of each other at all times

B. Some organelles are more important than other organelles within a cell.

C. Only up to three organelles may interact with each other at any given moment in time.

D. Various organelles within a cell interact with each other to carry out life processes.
