Answer:
ionic, hydrophillic,polar
Explanation:
non polar compounds dissolve in non polar solvents like alcohol and hydrophobic substances generally repel water .
Answer:
After watching a plant for a week, you determine it needs more sunlight.
Explanation:
Inference is a process by which, through certain data, a conclusion is reached. Other synonyms for inference are conclusion, implication, ilation and consequence.
Accordingly, an inference is made when after watching a plant for a week, you determine that it needs more sunlight. This was a conclusion based on data.
Not all inferences offer true conclusions, even with data analysis. It is possible to state that all dogs are furry animals with four legs, but it cannot be inferred that all furry animals that have four legs are dogs.
Inferences usually arise from an analysis of characteristics and probabilities. If someone makes reference to an animal with four legs, hairy and wagging its tail, it can be inferred that the most certain thing is that it is referring to a dog.
Not to be too picky, but the question ought to say a positively charge ion rather than atom.
I will assume that is what you mean. An ion, using ordinary means, will be positive if it loses electrons (which are negative).
An ion can never gain protons. Left alone, the nucleus will remain unchanged for the rest of eternity. D is wrong.
C is wrong. If electrons are gained, the ion will go negative.
B is wrong for the same reason D is. An ion can't gain protons and it can't lose them.
A is the answer.

Overfishing occurs when more fish are removed from an ecosystem than can be maintained by the population,
Overfishing can lead to significant population declines in economically important species. The passage describes

According to the passage, which mechanism explains the observed changes in fish size over time?
A. Smaller fish produce fewer eggs than larger fish do, so they contribute fewer offspring to the next
generation.
B. Fish that are small enough to escape fishing nets are more likely to survive than larger fish.
C. Scientists found that Atlantic silversides exhibited changes in feeding and foraging rates after four

D. The average size of pink salmon returning to spawn decreased from 6.0 pounds to approximately 4.5
