Hee Sun drew an electron dot diagram of a silicon atom as shown. In addition to changing the symbol to C, how would this diagram

compare with an electron dot diagram of a carbon atom (C)? The dot to the left of the symbol would be removed in the diagram for carbon. The same number of dots would appear in the diagram for carbon. There would be two dots above and to the right of the symbol in the diagram for carbon. The single dots would be replaced with two dots on each side of the symbol in the diagram for carbon

Answer: The same number of dots would appear in the diagram for carbon.

Explanation:

Electron dot structure are structure in which dots are used to represent the number of valence electrons of an element in compound. These electrons dots are placed around the chemical symbol of that element.

In electron dot structure of silicon, there are four dots present around the symbol 'Si' because their are four valence electrons present in the valence shell of the silicon atom.

Also in electron dot structure of carbon, there are four dots present around the symbol 'C' because their are four valence electrons present in the valence shell of the carbon atom.

So, the number of dots  would appear in the diagram for carbon will be same.

Brut [27]

Answer:

Total four genotypes and its frequency  

SsWw – 4/16

ssWw- 4/16

Ssww - 4/16

ssww - 4/16

Phenotype –  

SsWw – Heterozygous  Spotted skin and heterozygous wooled hair

ssWw  - Homozygous non-spotted skin and heterozygous wooled hair

Ssww  -  Heterozygous  Spotted skin and Homozygous non -wooled hair

ssww  - Homozygous non-spotted skin  and Homozygous non -wooled hair

Explanation:

Given -

Allele for spotted skin is "S"

Allele for non-spotted skin is "s"

Allele for Wooly hair is "W"

Allele for non-wooly hair is "w"

Allele "S" is dominant over "s"

And Allele "W" is dominant over "w"

Cross is carried out between heterozygous spotted, non-wooly man and heterozygous wooly-haired, non-spotted woman

Genotype of heterozygous spotted, non-wooly man - Ssww

Genotype of  heterozygous wooly-haired, non-spotted woman - ssWw

Ssww * ssWw

Phenotype –  

SsWw – Heterozygous  Spotted skin and heterozygous wooled hair

Three cells each contain a 98% water wash were soaked in different solutions cell number one is so funny solution containing 100
stepladder [879]

Answer: Cell number one is an hypotonic solution, cell number two is an isotonic solution, and cell three is an hypertonic solution.

Explanation:

Cell number one which is a 98% water content is added the 100% water solution, water moves from low to high concentration. Therefore, the water moves from the solution into the cell, which is hypotonic.

Cell number two which is a 98% water content added with a 98% water solution. These two solutions are equal to one another, so the water does not move. This is isotonic.

Cell number three which is a 98% water content added with a 80% water solution. Water moves from high to low concentrations, so water moves from the cell to the solution. The water leaves the cell, which is an hypertonic.
