Yes A is the correct answer
Answer:
c-hormonal hyperplasia
Explanation:
When there is increase in the number of cells and tissues that appear normal under the microscope,Hyperplasia is said to occur.If these occur in cells of an endocrine gland of a system,then it is refers to as hormonal hyperplasia.
Therefore during pregnancy,the proliferation of the glandular epithelium in a pregnant woman (and at puberty in a females are examples of hormonal hyperlasia.
Its possible causes are;
a surge in local production s of growth factors,
In the numbers of growth factors receptors on the cells receptive to the factors,
and due to activation of specific intrancellular signalling pathways.
It is for the cells to make protein.
Answer:
The correct answer would be A) ribosomes.
A ribosome is a vesicular structure present in both prokaryotic and eukaryotic cells. They consist of ribosomal RNA and associated proteins.
They are the site of translation in both prokaryotic and eukaryotic cells.
They are made up two units which are called large sub-unit and small sub-unit.
In prokaryotic cells, 70S ribosomes are present which are made up of 50S large sub-units and 30S small sub-units.
In eukaryotic cells, 80S ribosomes are present which are made up of 60S large sub-units and 40S small sun-units.
