Answer:
A. Equator
Explanation:
There is an equal number of hours of daylight and nighttime in the Northern Hemisphere because Earth's axis is not tilted in this position. The Northern Hemisphere has the fewest hours of daylight, and the North Pole is tilted away from the sun.
The naming of a Jewish child is a most profound spiritual moment. The Sages say that naming a baby is a statement of her character, her specialness, and her path in life. For at the beginning of life we give a name, and at the end of life a "good name" is all we take with us. (see Talmud – Brachot 7b; Arizal – Sha'ar HaGilgulim 24b)
Further, the Talmud tells us that parents receive one-sixtieth of prophecy when picking a name. An angel comes to the parents and whispers the Jewish name that the new baby will embody.
Yet this still doesn't seem to help parents from agonizing over which name to pick!
So how do we choose a name? And why is the father's name traditionally not given to a son – e.g. Jacob Cohen Jr., Isaac Levy III? Can a boy be named after a female relative? Can the name be announced before the Bris?
Jewish Customs
Naming a Jewish baby is not only a statement of what we hope she will be, but also where she comes from.
Ashkenazi Jews have the custom of naming a child after a relative who has passed away. This keeps the name and memory alive, and in a metaphysical way forms a bond between the soul of the baby and the deceased relative. This is a great honor to the deceased, because its soul can achieve an elevation based on the good deeds of the namesake. The child, meanwhile, can be inspired by the good qualities of the deceased – and make a deep connection to the past. (Noam Elimelech - Bamidbar) from http://www.aish.com/jl/l/b/48961326.html
Answer/Explanation:
Sexual reproduction is a a combination of chromosomes from each mate. Since each mate has different pairs, when combined they produce a completely different product.
This product has half of the characteristics from both sides.
Below is an example of how this works. The bold cells are from one mate and the other is from the other.
X ---> >< <--- X
X ---> >< <--- X
X ---> >< <--- X
X ---> >< <--- X
X ---> >< <--- X
As shown, the cells broke in half and combined with the other half forming a cell of 50/50. With this process it never created an identical offspring but different ones each time since different parts of the cell combines in different ways but still remains half of one and half of the other.
The first description of the DNA (deoxyribonucleic acid)chain was done by Watson and Crick in 1953, the nucleotides that constitute the DNA are four: cytosine (C), guanine (G), timine (T) and adenine (A). When doing a model is essential to remember that cytosine ONLY joins guanine and timine only link adenine, this is due to the size and chemical properties of each molecule. Later, another related and similar and molecule was discovered, the ribonucleic acid or RNA, which also is constructed by nucleotides.
In both cases, the nucleotides are compound of 3 main components: a nitrogen base, a pentose and a phosphate. When the molecule lacks the phosphate group, is called nucleoside. Depending on the chain ( DNA or RNA) the nitrogen base derives from purine (adenine and guanine) or pyrimidine (cytosine or timine) just in the RNA instead of timine is uracil (U)
The union is established between adjacent molecules through the phosphate, while among each other through the nitrogen base-remember C=G and T or U=A. The core of each molecule is the pentose. Therefore the best representation of the molecule is attached
