Hello!!! Princess Sakura here ^^
Explanation:
The sun, earth, and moon are held together by gravity, and they interact in lots of ways. The moon orbits the earth because of the pull of the earth. The tides are another interaction in the sun, earth, and the moon system. The tides happen because the moon and sun pull on the oceans, causing them to rise and fall each day.
1) The correct answer is: 128 combinations.
The genetic combinations that are possible through independent assortment can be calculated as 2^n; where n is the number of different chromosomes.
So, using this formula for 7 chromosomes:
2^7 = 128 different combinations.
2) For a zygote produced by two barley parents, the number of possible genetic combinations can be calculated as: 2^n * 2^n
So, for 7 chromosomes: 2^7 * 2^7=16384
<span>ion
positive
An atom normally has exactly as many electrons as protons, and has 0 overall charge. And a charged atom is called an ion. An ion may have either a positive or negative charge depending upon if it has fewer electrons than protons, or more electrons than protons. Since in this case, it lost an electron, that means that there's more protons than electrons, so the atom has a positive charge since protons have a positive charge.</span>
