Answer:
Earth's outer core is a fluid layer about 2,400 km thick
Explanation:
composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km beneath Earth's surface
Answer:
Hyperpolarization
Explanation:
At the synapse, neurotransmitters bind to neurotransmitter receptors in the postsynaptic neuron’s plasma membrane. This results in the opening of the ions channels and the flow of specific ions to change the voltage across the membrane. An inhibitory neurotransmitter inhibits the firing of the action potential by making the inside of the membrane more negative. It is called hyperpolarization (inhibition).
It may occur when the neurotransmitter opens the Cl– or K+ channels to allow the movement of chloride ions into the cell while permitting the outward movement of potassium ions to make the inside of the cell more negative.
Answer:
the answer is D :)
Explanation:
Active transport uses energy molecules to move particles like sodium, against their concentration gradients, from areas of low concentration to areas of high concentration.
Genes are segments of deoxyribonucleic acid (DNA) that contain the code for a specific protein that functions in one or more types of cells in the body. Chromosomes are structures within cells that contain a person's genes. Genes are contained in chromosomes, which are in the cell nucleus.
Endo = enter
This means when things enter into the cell, I hope this helped
