Answer:
C
Explanation:
The meninges are the membranous tissues that cover the spinal cord and the brain, providing support and protection to these organs. They are of three layers.
A) The Dura mater
B) The arachnoid mater
C) The pia mater
The Dura is the outermost meningeal layer and lies directly under the vertebral column bones and skull. The subdural space is the space between the Dura mater and the Arachnoid mater.
The Arachnoid mater lies in the middle of the Dura and Pia mater. Under the Arachnoid layer is the subarachnoid space which contains the cerebrospinal fluid. The cerebrospinal fluid acts as a shock absorber and a cushion to the brain and spinal cord.
The Pia mater lies under the subarachnoid space and directly on the spinal cord and brain and is highly vascularised.
Answer:
The correct answer would be "Can prevent genetic diseases".
Cloning refers to the process of making an identical copy of organism, cell or DNA fragments.
One of the applications of cloning is eradication or prevention of genetic diseases.
It is done by isolating the correct or functional gene and make copies of it in in-vitro conditions.
The gene or DNA fragment is then inserted back into the cell.
With advancement in cloning process and understanding of stem cells, cloning process also favors tissues and organ harvesting which also help in reducing diseases.

Answer:
Streptococcus
Explanation:
Coccus (plural cocci) bacteria are those that are oval or spherical in shape when viewed under a microscope. Coccus bacteria end up forming different shapes when they reproduce or multiply.
When they grow in clusters, they are referred to as Staphylococci, when in chains, they are streptococci and when they are arranged in pairs, they are diplococci. Enterococci are arranged in short chains or in pairs but usually gram positive in nature.
The correct option is streptococcus.
