Answer:
Diffusion
Explanation:
The concept of diffusion states that molecules like to travel from areas of high concentration to low concentration.
Let's think about an example. Let's say you are having a party at your house and in one room there is 100 people and in the other room connected to it, there is only 10 people. What do you think is going to happen as time passes? Right, people are going to move to the room where there is less people so as to equally disperse themselves across the area. The same thing happens within our body with ions and gases.
Ions can diffuse into or out of cells based off their concentration gradients. If there are too many ions on one side, they will simply move to the other side. There are different types of diffusion. Passive diffusion and facilitated diffusion, but those are for a different conversation.
Ionic bonds are when atoms gain or lose electrons, giving it a charge (positive or negative), A covalent bond shares electrons and gets a neutral charge.
Therefore, our answer is D.
Final answer:- <span>D. sharing of electrons between atoms.</span>
Answer:
interphase
Explanation:
The cell cycle is divided into two main phases: interphase and mitotic phase (mitosis or meiosis).
Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division, (mitotic phase).
Interphase has three phases:
G1 or Gap 1 - the cell grows in size and duplicates organelles
S1-replication of DNA
G2 or Gap 2 phase- the cell adds volume to the cytoplasmand repicates more organelles.
The nucleus, which disappeared at the beginning comes back, including the general organelles like Cytoplasm and cell membrane, the DNA also turns back into long strains of DNA, the chromosome go.
