There are three types of artificial cloning:
Gene cloning: copies a few segments of DNA or genes.
Reproductive cloning: it copies the whole animal.
Therapeutic cloning: produces embryonic stem cells for experiments aimed at creating tissues to replace injured or diseased tissues.
Answer;
- A teacher takes the cap off a permanent marker. A few minutes later, students at the back of the classroom complain about the odor of the marker.
- A cooking school student burns a piece of toast. Soon, the entire kitchen smells like burnt toast.
- Toxic fumes produced by a chemical factory are detected in the air in a town several miles away.
<h3><u>Explanation;</u></h3>
- Diffusion is a type of passive transport that involves the movement of particles from a region of high concentration to a region of low concentration.
- <em><u>Diffusion takes place in liquids and gases, since their particles can move randomly from one region to another.</u></em>
- <em><u>Therefore, diffusion results from the random movement of particles in which the net movement is down the concentration gradient that is, from a region of high concentration to a region of low concentration.</u></em>
The stability of atomic nuclei relies on the forces within the atom that balance out the charge. The electrons have the power to make an atom negatively or positively charged, but neutrons allow the atom to be electrically neutral regardless. The gravitational pull of protons and neutrons in the atomic nuclei keeps the electrons in an orbit, and with less protons than neutrons, electrons will be pulled into the nuclei and make the atom unstable; with less neutrons than protons, the electrons will be repelled and make the atom unstable. Therefore, the number and ratio of protons to neutrons are the factors that make an atom stable.
Answer: ratio of neutrons to protons and number of protons and neutrons

Answer:
The plants at a light intensity of 1200 will produce more oxygen than the plants at 400.
Explanation:
Sugar burns and turns black. A completely new substance was formed, which is the main pointer for it being a chemical reaction. More evidence would be change of color, odor, and the fact that flammability is a chemical property so setting something on fire would be a chemical change.
