Biology
1 answer:
svetoff [14.1K]3 years ago
4 0

Answer:

Secondary waves are also called S waves. As they pass through a material, the material's particles are shaken up and down or from side to side. Secondary waves rock small buildings back and forth as they pass. Secondary waves can travel through rock, but unlike primary waves they cannot travel through liquids or gases.

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six
Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

A metal in group 16 of the periodic table can become a chemically stable ion by
vova2212 [387]

Answer : A metal in group 16 of the periodic table can become a chemically stable ion by gaining 2 electrons.

Explanation :

The group 16 element are oxygen, sulfur, selenium, tellurium and polonium.

The general electronic configuration of group 16 elements is, ns^2np^4

As we now that there are total 6 electrons in p sub-shell. So, a metal in group 16 can become a chemically stable ion by gaining 2 electrons.

M+2e^-\rightarrow M^{-2}

Hence, a metal in group 16 of the periodic table can become a chemically stable ion by gaining 2 electrons.
