Explanation:
First one should be true because neutrons don't carry a charge therefore they won't affect the overall charge of the atom.
Second one should be positively charged, dense, and contains most of the mass of the atom
Bacteria protects the cell in your intestine and helps us absorb fatty acids. It is harmful because when you have contact with it, the bacteria can reproduce in your body, damaging it and making you sick.
(Question 1 points 3)
No. There will be no water flow into or out of the fish without proper homeostatic processes. The body temperature of fish is regulated by the temperature of the water. the fishes only allow the solvent (water) to move across, but not the solutes. A fish is, after all, a collection of fluids floating in a fluid environment.
(Question 2 points 3)
The fish will not experience "bloating" or "dehydration” because in nature all organisms maintain normal conditions through homeostasis. It is the tendency toward a relatively stable equilibrium maintained by physiological processes by the body. Gills of fishes, enzymes help in maintain. Humans drink water in case of dehydration.
(Question 3 points 3)
Fish are the cold-blooded creatures of God. Most of the fishes cannot control their internal body temperature by themselves just like human beings. In order to stay at a normal and a healthy temperature, or to obtain temperature homeostasis, the fish seek warmer or colder water for water retention when they face the excessive water loss.
Dr. Blackwell caused rats to stop breathing when he lesioned their MEDULLA.
When doctor Blackwell induced a lesion in the rats' medulla, he discovered that the rats stopped breathing. He explained this observation by saying that the medulla has functional role to play in the breathing process of rats.
