Answer:
Sickle cell anemia is an inherited condition in which there aren't enough healthy red blood cells to carry oxygen through an individual's body. The red blood cells of a healthy individual are flexible and round, and they move through blood vessels with no problem, transporting oxygen successfully. However, a person with sickle cell anemia has rigid, sticky red blood shaped like sickles or crescent moons. These cells often get stuck in small blood vessels, which can slow or block blood flow and oxygen delivery to different parts of the body.
The sickle cell anemia trait is found on a recessive allele of the hemoglobin gene, while the regular red blood cell trait is found on the dominant allele. This means that a person must have two copies of the recessive allele (one from their mother and the other from their father) to be born with this condition. People who have one dominant and one recessive allele or both dominant alleles will have healthy red blood cells.

Answer:
Solid
Explanation:
A radio device is a solid type of matter.
- Matter is anything that has weight and occupies a space
- There are three main categories of matter which are solid, liquid and gas
- A solid state of matter is made up of substances with a definite volume and a fixed shape.
- A radio has a fixed shape. Most of the come in a solid cuboidal or cube shape
- The volume of this three dimensional body can be measured which connotes the space it occupies at any given time.
- The mass of the radio can be taken using a balance.
The process for connecting two monomers together is called dehydration synthesis. Dehydration means
“removal of water” and synthesis means “to join together”. So in this
process, two monomers are covalently bonded by the removal of a
water molecule. Each organic monomer has a hydroxyl group on
one side and a hydrogen on the other. When two monomers line
up side by side, they will have these two functional groups facing one
another. The H and the OH will break off of their respective
monomers and bond forming a water molecule. This is the dehydration
part of the process. Each monomer now has a carbon atom that needs
to covalently bond with something, so they bind to each other forming
a polymer. That is the synthesis part of the process.
