Answer:

Plasmid DNA play a important role for survival of a prokaryotic cell.

Option D is correct one.

Explanation:

In addition to the chromosome, many prokaryotes have plasmids, which are small rings of double-stranded extra-chromosomal ("outside the chromosome") DNA. Plasmids carry a small number of non-essential genes and are copied independently of the chromosome inside the cell. They can be transferred to other prokaryotes in a population, sometimes spreading genes that are beneficial to survival.

For instance, some plasmids carry genes that make bacteria resistant to antibiotics. (These genes are called R genes.) When the plasmids carrying R genes are exchanged in a population, they can quickly make the population resistant to antibiotic drugs. While beneficial to the bacteria, this process can make it difficult for doctors to treat harmful bacterial infections.

Answer:

<u>The process of photosynthesis occurs in the chloroplast</u>. Photosynthesis can be described as a process in which plants convert water and carbon dioxide into glucose and oxygen. Oxygen is the by-product of the reaction. The energy for this reaction is taken by the chloroplast by trapping light energy of the Sun.

The reaction for photosynthesis can be written as:

6CO2 + 6H2O → C6H12O6 + 6O2

<u>The process of cellular respiration takes place in the mitochondria.</u> Respiration can be described as a process in which glucose and oxygen get converted into carbon dioxide and water. Energy is released by this process which is used for many cellular activities. Hence, mitochondria is known as the powerhouse of a cell.

The reaction of cellular respiration can be summed up as:

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP

Both, these processes provide energy for the working of cells.

The parasympathetic division is also called the craniosacral division because its preganglionic neurons are housed within nuclei
sergij07 [2.7K]

Answer:

True

Explanation:

The cell bodies of preganglionic neurons of the parasympathetic division are present in the nuclei of four cranial nerves in the brainstem. These four cranial nerves are III, VII, IX, and X. Likewise, some of the cell bodies of the preganglionic neurons of the parasympathetic division are present in the lateral gray matter of the second to fourth sacral segments of the spinal cord. Therefore, the parasympathetic division is also known as the craniosacral division. The axons of the parasympathetic preganglionic neurons are called craniosacral outflow.

Similar to all white blood cells, lymphocytes used in the adaptive immune system are produced in the _______.
Nutka1998 [239]

The answer is letter D.  A group of white blood cells that has of small and large lymphocytes. The small lymphocytes bear variable cell-surface receptors for antigen and are responsible for adaptive immune responses. There are two main group of small lymphocyte—B lymphocytes (B cells) and T lymphocytes (T cells). Large granular lymphocytes are natural killer (NK) cells, lymphocytes of innate immunity.
