Answer:
GTP.
Explanation:
Ras MAP kinase is an important cell signalling process that are important for cell survival, cell multiplication and cell proliferation. The phosphorylation at particular reside play important role in this signalling.
The binding of GDP with Ras indicates that Ras pathway is inactive. The exchange of GDP with GTP activates the Ras pathway and initiates the signalling cascades that further activates the MEK signalling. Hence, Ras is active when bound to GTP.
Thus, the correct answer is option (c).

Horses and zebras can be bred to produce a zorse, which is sterile. Which is most likely the reason zebras and horses are considered separate species?
Answer:
The correct answer is - a. The Porifera are asymmetrical, while the Cnidaria are radially symmetrical.
Explanation:
In biology, symmetry f the body is meant the presence of a pair of organs in an orderly manner that if divide the body each part is a mirror of the other. In the phylum Porifera have asymmetric body plane.
Some animals develop into adults with radial symmetry. Cnidaria adults have radial symmetry type of body plans that eans if they are cut from the middle they divide in the two equal organs into both sides.
Answer:
Nuclear fission is the splitting of atoms while fusion is the combining
Explanation:
fission does not occur naturally while fusion occers in stars
