Water is considered a polar molecule because _____. it has partial positive and negative charges at each end
it expands when it freezes
it dissolves solutes

Answers

Answer: Option (a) is the correct answer.

Explanation:

A water molecule contains two hydrogen atoms and one oxygen atom. The chemical formula of water is $H_(2)O$ .

Here, hydrogen is electropositive whereas oxygen atom is electronegative in nature. Hence, oxygen atom pulls electrons from hydrogen atom and as a result partial positive charge develops on hydrogen and partial negative charge develops on oxygen atom.

Therefore, molecule of water becomes polar in nature.

Thus, water is considered a polar molecule because it has partial positive and negative charges at each end.

Answer:

The answer is It has partial positive and negative charges at each end.

Explanation:

When a neutral molecule has a positive area at one end and a negative area at the other, it is a polar molecule. Water is a polar molecule, because there is an irregular distribution of electron density in it. This means that water has a negative partial charge near the oxygen atom and a positive partial charge near hydrogen atoms.

A fish that normally lives in salty water is placed in a tank containing fresh water. What do you think will happen to the cells of the fish?

Answers

Well, freshwater doesn't have the salt that a saltwater fish needs so the fish's cells(hypertonic cells) would become hypertonic which cannot mix with that fish's structure. Therefore, the fish, well, the fish would die.

Do the results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription? Why or why not?Do the results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription? Why or why not?
No, because histone modifications do not affect transcription
No, because the results demonstrate only a correlation between altered histone modifications and reduced transcription
Yes, because the observed changes in histone modifications are consistent with reduced transcription.
Yes, because histone modification is the only regulatory mechanism that could affect transcription

Answers

The correct answer for the question that is being presented above is this one: "Yes, because the observed changes in histone modifications are consistent with reduced transcription." The results shown in Figure 19.5 prove conclusively that histone modifications are causing reduced Hnf4a gene transcription because the observed changes in histone modifications are consistent with reduced transcription.

All of these are placental mammals excepta. porpoise.
b. mouse.
c. elephant.
d. opossum.

Answers

teh answer is d. opossum

Answer:

The correct answer is the option: d. opossum.

Explanation:

Hello! Let's solve this!

A placental mammal is a mammal that is viviparous and its young fully develops in the mother's womb.

Mammalian metatheria are those that develop inside the marsupial pouch.

An example of the latter are marsupials and among them the opossum.

So we conclude that the correct answer is the option: d. opossum.
