Describe the size and scale of an atom. Explain the relative size of the nucleus in relation to the size of the entire atom.

1 answer:

7 0

The size of the nucleus of an atom is about 10 raise to power 15 meter, which basically proposes that it is about 10 raise to power -5 or 1/100,000 we can say of the size of the entire atom. A good comparison of the nucleus to the atom is just like a pea in the midst of a track. The volume of the atom is 2 x 1013 times larger than its nucleus.

What happens if you don't get your wisdom teeth out?

Blababa [14]

Some wisdom teeth is completely unharmful, as long as your mouth have enough space for it to grow healthy and you are sure that you can clean it properly, they make no problems.

However, if your mouth is too small, wisdoms teeth may grow in a tilted angle, this is big problem indeed. It may cause damage to other teeth since it doesn't grow upright. In addition, it may be a big problem to clean it properly so tooth decay may occur.

Therefore, it's better to visit the dentist and see if your wisdom teeth cause problem and whether you need to remove them or not.

The ABO blood group assorts independently of the Rhesus (Rh) blood group and the MN blood group. Three alleles, IA , IB , and i,

Eva8 [605]

Answer:

Part 1:

The mother’s genotype is ii, rr, MN

The father’s genotype is IAIA/IAi, Rr, MM

Part 2:

Approximately 1/32 (3.125%) of children can be expected to have the stated blood types.

Explanation:

Part 1:

The mother has blood types 0, Rh- and MN. Therefore, her genotype has to be ii, rr, MN.

The father has ABO type A. His ABO genotype may therefore be either IAIA or IAi, as both are compatible with type A offspring with a type 0 mother. His Rh genotype must be rr, since his Rh- child necessarily has to have inherited one r allele from each parent. Finally, his MN genotype has to be MM since both alleles are codominant.

Part 2:

Using the given data, we build the following Punnett chart:

IA R N IA r N i R N i r N

IA R M

IA R N

IA r M

IA r N

IB R M

IB R N

IB r M X

IB r N

Note that, of all 32 possible combinations, only a single one of them (marked with “X” produces a genotype which matches the desired blood type, as follows:

genotype: IBi, rr, MN

blood type: B, Rh-, MN
