Answer:
The Exosphere
Explanation:
The Exosphere is the farthest away from the Earth and the least dense. Going towards the Earth a space ship would pass through the Ionosphere, then the Stratosphere where high flying airplanes can be found, and finally closest to the Earth is the Troposphere which is the thickest layer where all our weather takes place.

Oral cavity

its first organ from which food enter
An X-linked gene is a gene on the X chromosome.
When a gene is available on the X chromosome, not on the Y chromosome, it is supposed to be X-linked. X-linked genes have different inheritance designs than genes on non-sex chromosomes or can say on autosomes. That is on the grounds that these genes are available in various duplicate numbers in males and females.
These disorders are significantly more typical in men than they are in females because of their X-linked inheritance design.
Females who are heterozygous for disordered alleles are supposed to be carriers, and they ordinarily show no side effects themselves. Children of these females have a 50 percent chance of getting the disorder, yet girls have minimal possibility of getting the disorder (except if the dad likewise has it), and will rather have a 50 percent chance of being carriers.
The alleles for specific circumstances including a few types of color blindness, hemophilia, and muscle dystrophy are X-linked.
