<span> Before agriculture was developed people mostly were nomadic in nature. They moved from place to place in search of food. Some of them were groups of hunter gatherers as well. When agriculture started people also started to settle down in groups. This led to the development of civilization and in modern day cities and towns. The first agricultural practices were started beside the river banks due to the reason that the soil was very fertile and water for irrigation was also easily available. </span>

Phoenix [80]

Answer:

SER, they are capable of synthesizing testosterone of Adrenocortical cells.

Explanation:

Adrenal smooth microsomal cells are  enriched in smooth endoplasmic reticulum SER, membranes of which contain high levels of translocation apparatus and oligosaccharyltransferase complex proteins. STEROID-SECRETING CELLS are characterized by abundant smooth endoplasmic reticulum (SER). These cells synthesize cholesterol as a precursor for steroid hormones or take up this substrate from plasma lipoproteins. Many of the enzymes for sterol and steroid synthesis are localized in the smooth-surfaced endoplasmic reticulum. This organelle is particularly prominent in cells of the inner zones of the adrenal and fluctuates in amount and configuration in response to hormonal stimulation and sterol levels.

There are 1000 micrometres (um) in a millimetre (mm).
Vesna [10]

Answer: The length of the cell in millimetres is 0.0015.

Explanation:

Given conversion :

1000\mu m=1mm

Thus 1\mu m=\frac{1}{1000}mm=0.001mm

Given : Length of the cell = 1.5 micrometers (\mu m)

To find: Length of the cell in milllimeters (mm)

Length of the cell in milllimeters (mm) = 1.5\times 0.001mm=0.0015mm

The length of the cell in millimetres is 0.0015.
