The nucleus of an atom contain protons and neutrons, which make up most of the mass of an atom.
The answer would be 2 and 3 ( 2nd answer choice)
A. The hosts body could reject the transplanted stem cells
Answer: The correct answer to the question is option 2
If pressure is applied to a rock until it's volume is reduced by one half how the new density compares to it's original density is ; THE NEW DENSITY IS TWICE IT'S ORIGINAL DENSITY.
Explanation: Density is defined as mass divided by volume,density increases with pressure and it's determined by spaces between atoms in the object being measured.
Density is directly proportional to Pressure,so when pressure increases, Density increases and when pressure decreases,density decreases.
Density is indirectly or inversely proportional to temperature. so when pressure and density increases, temperature remains constant.
This is applicable to the scenerio with the rock in the question,as the pressure on the rock is increasing,the density is increasing too.
Answer:
c) degree of myelination of the axon
Explanation:
Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.
Factors that determines the rate of conduction velocity are:
- axon diameter-larger diameter axons have a higher conduction velocity
- sheeth-a myelin sheath increases the rate of impulse propagatio
Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.
