How should you change this image to represent an ionic bond between sodium and fluorine?
erma4kov [3.2K]
This is kind of hard to show without the picture, but to make an ionic bond with Na and Fl you would have the sodium move an electron to the fluorine, so the answer is C!  This is because of the fact that sodium has an outer shell valance electron (so it's unstable) and the fluorine would accept that because it is missing an electron in the outer shell.  So this sharing would lead to the bond being created!

Which of the following is an example of an environmental variation?
Lera25 [3.4K]
I believe the example of an environmental variation in the above question is, A. Marge dyes her hair blue. Variation represents any difference between cells, individual organisms, or groups of organisms of any species caused by either genetic differences or by the effect of environmental factors. Environmental variation is the ability of an organism to alter its phenotype depending on environmental conditions.

which of the following balances performs in a closed compartment with no air currents to disturb measurement
Andrei [34K]

A balance that performs in an enclosed compartment  with no air currents to disturb is called an analytical balance.

Analytical balances are instruments used for precise and determination of mass of matter. They are accurate and very precise instruments. They require a draft-free location on a solid bench that is free of vibrations.

Analytical balances of today are digital and have built in calibration weights to maintain accuracy. Older versions usually require to be manually calibrated using specific  standard weights.

A climate zone is an area that is defined by two main factors. What are they?
MA_775_DIABLO [31]

Answer:

Temperature and precipitation.

Explanation:

Climate is defined as long-term climate patterns in a location. Looking at average temperature and precipitation through time is the simplest way to characterize the climate.

Temperature and precipitation are the two most significant factors in the climate of a place. Obviously, the annual average area temperature is significant, but the annual temperature range is important as well. Some locations range from the highest to the lowest temperature significantly wider than others. Average precipitation is very essential, but the annual change in precipitation is equally important. Some regions experience approximately the same precipitation year-round. For half of the year, other locations have very low precipitation while the other portion of the year has lots of precipitation.
