Answer:
The correct answer is -
exposure of the opposite environments to the species and see if they are able to be active in cold waters.
If they are then species of organism in Maine and could have more ice-nucleating agents which are responsible for their high ability for activity in cold waters.
Explanation:
To test the assess if the Maine species of organisms are especially able to be active in cold waters an experiment can be designed where one needs to place the species or animals from Maine and Bahamas in reverse conditions.
Maine animals are placed in warm water environments and species from the Bahamas can be placed in cold water. Finding if they are able to adapt in reverse condition by calculating various processes and motion, if yes then it shows that it is not a special ability to survive in cold temps. However, if it is not then the Maine poikilotherms are specially designed for their environment. In case of yes then species of organism in Maine and could have more ice-nucleating agents

Gametes
When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes. When a cell divides by way of meiosis, it produces four cells, called gametes. Gametes are more commonly called sperm in males and eggs in females.
DNA make up the chromosomes that are then passed off to the parent's offspring. The DNA is in the chromosomes and it translates the genes to determine traits
Answer:
a mutation that blocks the GTPase activity of Ras
Explanation:
A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
