Answer:
The wave like motion of a tube.. generally oesophagus due to which, food goes down
Explanation:
peristalsis have alternative contraction and relaxation movements
A neuron is nerve cells that transfer information within the body, chemically over short distances, using electrical signals over long ones.
As it turns out, most resting neurons are permeable to Na+ and CL- as well as K+. K+ will try to drag the membrane potential toward its (positive) equilibrium potential, while NA+ try to drag the membrane potential to its negative equilibrium potential.
The real membrane potential will be between NA+ and K+ of equilibrium potential<span>. However, it will be closer to the equilibrium potential of the ion type with higher permeability.</span>
Answer:
The correct answer would be Pp.
The genotype of one parent is PP. Thus, it will produce only one type of allele, that is, P.
Similarly, the genotype of another parent is pp. Thus, it will produce only one type of gamete, that is, p.
The cross would produce offspring with only one type of genotype, that is, heterozygous Pp.
The phenotype of all the offspring will be purple as it is a dominant trait.
Without the proper balance of water, chemical reactions in cells could not take place

Answer:
C. The sun's angle
Explanation:
The amount of energy received by an area depends on the suns angle from earth's surface.
Different areas of the earth receive different amounts of solar energy. As the earth revolves around the sun and the sun rays fall directly at the Equator, that makes areas lying at the equator are warmer while areas at the north and south poles receive minimum solar energy and remain colder.
Hence, the correct answer is " C. The sun's angle".
