Answer:

Radioactive Elements

In elements with more than 83 protons, all of the isotopes are radioactive. ... The force of repulsion among all those protons makes the nuclei unstable. Elements with more than 92 protons have such unstable nuclei that they don't even exist in nature.

Why do scientist use the light year instead of astronomical units to measure the distance between stars ?

Evgesh-ka [11]

Astronomers use light years to measure distances in space because space is so massive and distances so far that conventional numbering is inadequate and unmanageable. One light year is a distance measurement equivalent to six trillion miles.

Use the probability method to calculate the genotypes and genotypic proportions of a cross between AABBCc and Aabbcc parents.

lora16 [44]

For this, you need to use Punnett squares.

You know the genotype of the parents, and for the cross, you need to separate into two alleles, both genes.

AABBCc divided like ABC and ABc.

Aabbcc divided like Abc and abc.

Now you can cross them, and all probabilities will be:

AABbCc, AaBbCc, AABbcc and AaBbcc

So, you could say 25% of the offspring will be AaBbCc, 25% AaBbcc, 25% AABbCc, and 25% AABbcc

Color blindness is a recessive x-linked trait in humans. in a family where the mother is color-blind and the father is normal, t

melisa1 [442]

Color blindness is a recessive x-linked trait in humans. In a family where the mother is color-blind, and the father is normal, the probability of their having a color-blind son is 100%.

Color blindness is a recessive x chromosome liked recessive disease which is more prone in males than in females. As the mother is color-blind she has both the alleles of colorblindness while the father is normal with both x chromosome and y chromosome normal.

So if the parents have a boy, he will always receive an x chromosome with colorblindness gene from the mother and a normal y chromosome from the father always. Thus, the probability of having a colorblind boy will be 100%.
