Jim was observing a frog embryo in which the brain and spinal cord were formed. In what stage is the embryo?

A. neurula stage
B. blastula stage
C. gastrula stage

A. neurula stage

Explanation:

About 8 hours after gastrulation (which is the formation of the mouth, gut, and anus) the embryos go through the process of neurulation, which is the formation of the brain and spinal cord.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

i think its white blood cells
