B. by the sharing of electrons
Answer choices A and C are incorrect because covalent bonds form as a result of electrons (protons are kind of irrelevant). Answer choice D is incorrect because it describes an ionic bond.

Answer:
The answer "to obtain an average that accurately represents fish from this area
" should be the answer because a large sample size is crucial for being a good representation of the whole population, and by taking many samples from each fish scientists can then determine the average mercury concentration within each fish, which then allow them to give a good estimate of the mercury concentration in the fish population because of their sufficient sample size.
Explanation:
A). The increase in genetic variation of a population
I just took 4.05 Animal Adaptations
Hello there,
They transfer the energy with or without medium (MATTER)
Since radiation is transferred through wave, it does not need any form of objects to pass through.
For example, the heat that radiation through the sun could be felt without any objects that connect us from The sun itself.
Answer:
The blue arrows in circles indicate that cool air is sinking
Explanation:
Warm air is less dense than cool air. For this reason, warm air rises, creating a low pressure region, and cool air, which is more dense than warm air, sinks creating a high pressure zone. In this description, the red arrows represent the hot air rising up to the sky, and the blue arrows represent the cool air sinking down. The reason warm air is less dense is because its molecules are further apart than when it is cold, making it lighter per cubed square foot.
So, we can conclude that option a) Warm air is rising is incorrect, because the warm air rising is represented by the red arrows pointing up form the land to the sky.
Options c) Cool air is less dense and d) warm air is more dense are also incorrect, because as mentioned before, cool air is more dense than warm air.
