dsp73

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.

2. In a certain fish, blue scales (BB) and red scales (bb) are codominant. When a fish has the
Evgen [1.6K]

Upon crossing BB with bb, we will get a hybrid of Bb.

  • Codominance is a phenomena in genetics where two alleles (different forms of the same gene) express themselves equally in an organism. As a result, characteristics linked to each allele are shown at the same time.
  • The MN blood group system in humans is an illustration of codominance. M and N alleles control the MN blood type. Red blood cells from people who are homozygous for the M allele carry a surface molecule known as the M antigen. On their red blood cells, those who are homozygous for the N allele contain the N antigen. A heterozygote is a person who carries both antigens.
  • (a) Genotype of blue scales fish will be BB.
  • (b) Genotype of blue scales fish will be bb.
  • (c) Genotype of blue scales fish will be Bb.

So, in this case B and b alleles will express equally.
