Answer:
Water is the most important element in our body and we need a constant supply of it to survive. Now in the scenario that you described is very important to make sure you boil the water because that is the best way to ensure that you killed any living organism (Virus, bacteria or parasites) that could endanger your life. So the answer to your question is A as it was said before but let me elaborate a little more.
Explanation:
Many times, water is contaminated by mosquito or bacteria that can cause among other problems Dysentery. This is an inflammation of the intestines that cause a lot of pain and a bloody diarrhea. This bacteria is spread through water or food and in many third world countries is the main cause of death among the population. When you boil the water the bacteria is killed and the water is safe for drinking. If you ever learn of someone developing such symptoms and they claim to have drank unsafe water, suggest them to go to the doctor intermediately. Their life is at risk.
Answer:
It will lose 1 electron
Its charge will be 1+, or simply (+)
Explanation:
Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.
The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+
For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+
<em>Davy made a model of the water cycle by adding some water inside a plastic bag, sealing the bag, and placing it in a sunny area. He noticed that the level of the water went down, and then some droplets appeared on the sides of the bag. which part of the water cycle caused water droplets to form on the side of the plastic bag? </em>
<em>(a) condensation (b) evaporation (c) precipitation runoff</em>
The part of the water cycle that caused water droplets to form on the side of the plastic bag would be condensation.
<h3>What is condensation?</h3>
It is a process whereby water vapor in the atmosphere condenses or turns back into liquid.
Condensation is as opposed to evaporation. The latter is a process whereby liquid water turns into vapor water. In other words, evaporation and condensation are words and opposites.
Both processes play a major role in the water cycle of the ecosystem.

<span>The two identical daughter cells resulting from mitosis and cytokinesis are identical in the following ways:1. Mitosis occurs when the nucleus of the cell divides into two identical nuclei, each with the same type and number of chromosomes. The cell's DNA is duplicated during this phase. Sometimes the cell's DNA isn't copied properly resulting in cancer-type cells. 2. Cytokinesis is when the cytoplasm divides into two identical daughter cells. Each cell is genetically identical and both are a similar size.

<u>Photosystem I is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by Photosystem I are used to produce the high energy carrier NADPH.</u>
