A jet stream forms high in the upper troposphere between two air masses<span> of very different temperature. The greater the temperature difference between the air masses, the faster the wind blows in the jet stream.
</span>.
.
So "Differences in temperature between two air masses" is the answer
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"function of snakes"
Snakes are elongated,legless,carnivorous reptile of the suborder serpents.Like all other squamates,snakes are exothermic,amniotic vertebrates covered in over applying scales.Many species of snakes have skulls with several more joints than their lizard ancestors,enabling them to swallow prey much larger than their heads with their highly mobile jaws.To accommodate their narrow bodies,snakes,oared organ appear one in front of other instead of side by side,and most have only one functional lungs.Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca.Legless lizard have eyelid and external ear.
A scale protect the body of the snakes,aids it in locomotion,allows moisture to be retained within,alters the surface characteristics such as roughness to aid in camouflage,and in prey capture (such as Acrochordus).
Snake scale originates from the epidermis.The integument of the snakes in covered with two primary scale type,both originating from the epidermis.Small scale over the dorsum and lateral surface of the snake.Whereas larger scales cover the vent rum.
Molecular homology, because it compares dna
Plant cells have what is perhaps the most complex outer coverings. Plant cell walls are made largely of cellulose which forms strong, highly rigid, almost indigestible coverings that protect the cell and gives it shape.
Primary growth or lengthening of plants results from mitotic division in cells of the apical meristem tissue. The apical meristem can be found in the top of plants. When the plant divides, it helps to lengthen it. The correct choice is C.
