Proteins can - primary secondary tertoary and quaternary structures.
Answer:
D
Explanation:
Vitamin C is one of the vitamins that humans can't produce in their liver. They need this vitamin from the external environment in the form of food. About 75- 90mg/day is it's the normal dosage. So, option D is correct.
The pia mater is the only meninges to continue into a brain sulcus after the brain surface.
What are meninges?
The skull and spinal cord are encased in three tiers of membranes called meninges. These are:
- The pia mater is the fragile inner layer.
- The arachnoid, a fluid-filled web-like structure that forms the brain's intermediate layer, is what gives the brain its cushioning effect.
- The dura mater is the name of the hard outer layer.
The term for the three gaps between the meninges-
- The gaps between the layers of the meninges are known as meningeal spaces.
- Epidural, subdural, and subarachnoid are the three clinically important meningeal compartments.
The function of meninges:
- It acts as a shock absorber, the CNS (central nervous system) will shield our brain from trauma harm, such as a knock to the head.
- They secure our central nervous system and prevent our brain from shifting inside our skull.
Therefore the correct solution is an option (A),i.e., pia mater.
The complete question is:
The only one of the meninges that follows the brain surface into a cerebral sulcus is the
a. pia mater.
b. alma mater.
c. dura mater.
d. arachnoid mater.

The glandular swelling is found on the back of the earthworm and is called C.litellum.
An earthworm is tube shaped and it belongs to the Annelida phylum. It is usually found in the soil, where it contribute to the level of fertility of the soil by feeding on the dead organic matter and by aerating the soil. Earthworms lack internal skeletons and they are hermaphrodites.
DNA replicates into RNA molecule after transcription using one of its strand as a template.
Explanation:
The Transcription is the process of RNA molecule formation and it involves three steps in it, which are namely, initiation, followed by elongation and at the end is the termination.
The DNA strand taken for the transcription is unwinded by the help of the enzyme which provides for the template. The template helps in the formation of complementary base pairing which results into the mRNA molecule. The RNA molecule thus, formed is processed after.
