In the winter bears hibernate because food is scarce during the winter, and it is also very cold. During hibernation a bears body temperature drops, and they do not go to the bathroom. This helps them preserve energy as they sleep throughout the winter. Which is what keeps them alive. Hope I could help!!:-)))
The answer is the plague, or the black death

The answer you're looking for is <u>D. Boiling points of various substances.</u> I got this answer because the independent variable is the thing in an experiment that is unaffected by any thing in the experiment, but has to be changed by the tester to find a change in the outcome of the dependent variable. It can't be A because depending on the temperature of the heated container must be different to reach the boiling point of different substances, for this reason, we also find out that D is the answer. I hope that this helps!
Answer:
Structure has been shown below
Explanation:
- In a Lewis structure, least electronegative atom is taken as central atom (except H)
- Total valence electrons of constituting atoms are used to construct Lewis structure
- A bond between two atoms are represented by a horizontal line or a dotted line (two dots).
- Spatial rearrangement of atoms are neglected in Lewis structure.
- H has one valence electron and O has six valence electrons. So, total valence electrons in are 8
- Lewis structure of has been given below.
