Do you think there is an upper limit to chromosome number? Explain.

There is a upper limit to chromosome number. The upper limit is caused by incomplete segregation of sister chromatids and trimming of the long arms.

Explanation:

There is a practical limit to the number of chromosomes related to how they can line up in homologous pairs for meiosis in sexually reproducing organisms.

They have a practical limit to number of spindle fibers that you can have in the cell during mitosis.

There is a fern with more than thousand chromosomes. The micronuclei represent loss of DNA from the genome and are lost outright through further cell divisions.

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.
