Answer:

When a nerve cell is stimulated, the cell membrane becomes MORE permeable to Na+.

Explanation:

When the action potential is fired, opening of Na+ ion channels in membrane makes it more permeable to the Na+ ions. The Na+ ions enter the axon and makes the inside of the membrane more positive. This is called as depolarization. Depolarization of axon is followed by depolarization during which K+ ion channels are opening to allow movement of K+ ion outside the axon and to make the inner side of axon membrane negative again.

Mitochondria are main sites of aerobic respiration. They are miniature biomolecular factories where food stuffs or respiratory substrates are completely oxidised to carbon dioxide and water. The energy liberated in the process is stored in the form of ATP.

Because of formation of ATP mitochondria are called <em>power</em><em> </em><em>hou</em><em>se</em><em> </em><em>of</em><em> </em><em>th</em><em>e</em><em> </em><em>cell</em>.

BRAINLIESTTT ASAP!!

For #1, the last choice is correct. A geocentric model means that the earth is the center of the universe while all other bodies orbit around it. A heliocentric model means that the sun is the center of the inverse while the other bodies orbit around it. The shared feature is that the other bodies in space move in circular orbits.

For #2, the first answer is correct. When the moon is between the earth and the sun, positions X and Z are being pulled by the moon’s gravitational force, creating high tides at these places. However, positions W and Y are experiencing low tides because no gravitational pull is making them high.

The lysosome functions in a cell like the _______ does in our bodies.
Troyanec [42]
Lysosomes remove waste at a cellular level.
They contain digestive enzymes, so they're like the digestive system.
The stomach digests food, so lysosomes could be considered like the stomach.
But then again, so do the intestines, small and large.
Since the stomach doesn't also work to remove waste though, I'd say the answer is probably large intestine, which finishes the digestive process and removes waste material.
