Answer:
The question is incomplete as the boxes of description is not given but the missing part is attached in the image-
Brain and spinal cord have a membranous covering made up of three layers, altogether known as meninges. These 3 layers are known as the Dura mater follows by the arachnoid mater and inner layer is the pia mater.
The description of the different layers are as follows-
1. Dura mater is the most superficial layer of the meninges. The superior sagittal sinus is present within this dura mater.
It creates tough inward folds that distinguished the cerebral hemispheres. Lines the inner side of the cranium in the skull.
2. Arachnoid mater is the middle layer present under the dura mater layer that surrounds the subarachnoid space. This layer is present Immediately deep to the subdural space.
3. Pia mater makes the deepest layer that follows the contours of the surface of the brain.
Answer:
In Hershey -Chase experiment , they proved the physical carrier of inheritance is nucleic acids not proteins.
Explanation:
Hershey- Chase <em>has proved genetic material is DNA. They experimented on Bacteriophage which are made of proteins and DNA. For this experiment they used radioactive isotopes of element. Phosphorous-32 was used to label the DNA and sulfur -35 was used to label amino acids in proteins.</em>
They found in experiment shortly after attacking on bacteria phage adhere on the surface, <u>inserts its DNA into the host , leaving its protein coat outside</u>. As they did not find any trace of sulfur-35 in the test medium.
after entering host body phage DNA multiplied in several copies. And after that they packed and assembled in protein coat.
After this experiment they concluded that DNA is the physical carrier of inheritance.

The cell plate grows outward from the center of the cell to the parental plasma membrane with which it will fuse thus completing cell division. Hope that helped
