Nylon is named as the most useful synthetic material. Nylon belongs to a family of materials called "polyamides."
Answer:
According to mass and volume, block density is 2 g/ml
Explanation:
Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.
In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.
The formula used to calculate the density is
ρ = 
Therefore, according to the mass and density of the block
ρ = 
= 2g/ml
Being the density of the block equal to 2 g/ml.
<em>The other options are not possible, because the values given do not correspond to the result of the equation.</em>
Answer:
Radiation oncologist.
Explanation:
Cancer is one of the most deadly disease and half of the world population died due to cancer every year. Cancer might occur due to the mutation in the genes that control the cell cycle.
The oncologist may be defined as the individual that has specialized in the cancer and its treatment. The different radiation might use to kill the cancerous cell and the radio elements are administered in the drugs used during the chemotherapy.
Thus, the answer is radiation oncologist.
D.
A parent with type A B blood can ever have a child child with type O blood.
Explanation:
An offspring gets an allele for blood type from every parent. Therefore unless both parents have blood type O the offspring cannot have blood type O.
A person with blood group O means they do not blood group antigen on their red blood cells. They cannot pass the antigens to their offspring. A person with AB means they have both antigens for A & B blood groups and can pass either to any of the offspring they have.
The passing down of the blood group alleles follow the Mendelian principles of independent assortment.
