Generalized Anxiety Disorder (GAD), Specific phobias, Agoraphobia, Social Anxiety Disorder, Panic Disorder, Separation Anxiety Disorder.
Answer:
Organisms that are in existence to day must have evolved from Ancestral species million of years ago.
Natural selection is the main driving mechanisms for evolution of new species.
Explanation:
Genreally organisms produce more
offsprings than they can provide for in a particular environment.
Because of thre limited resources available due to overpopulation, organisms must develop certain characteris or traits to survive.
Offisprings that survived must have inherited these traits from thier parents, while those without these traits will die.
Natural selection must be the mechanism for the selected organisms to withstand selection pressure of limited resources.
This is survival of the fittests by natural selection.
Answer: The sodium-potassium pump.Explanation:
The concentration of sodium and potassium inside and outside the muscle cells are important in the regulation of contraction. These concentrations differ when a muscle is relaxing or contracting.
<span><span>Contraction: potassium concentrations are higher outside the cell than inside the cell.</span><span>Relaxation: the potassium concentrations are higher inside the cell than outside the cell.</span></span>
hope this helps :)
Explanation:
75 J
Energy is neither related nor destroyed- it's simply converted to different forms. Forces are vectors with both mass and acceleration; they are interactions that have the ability to change an object's motion. As objects move, their potential energy (apprx 100 J) is converted to kinetic energy. However, friction a resistive force, which is formed from the conversion of an object's kinetic energy into heat energy, as two surfaces move along each other.
With the reduction of friction, the energy output should increase, as less energy is lost as heat. Thus, the output should be 75 J.
