<h2>Capillary Smooth Muscle Contraction</h2>

Explanation:

  • Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
  • Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
  • Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
  • All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction

Compare the normal allele for hemoglobin with the sickle cell allele. How does this difference affect the person’s red blood cel
Readme [11.4K]

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.

The process of DNA replication is described. Identify the enzyme that participates in each part of the replication process. DNA
Kazeer [188]

Answer:

Helicase

Explanation:

DNA replication is the process in which DNA makes copies of itself.

The process of DNA  replication is supported by several enzymes.

The initial step of DNA replication is unwinding of double stranded DNA which is catalyzed by helicase enzyme. Helicase enzymes breaks the hydrogen bond between the  DNA strands and prepare them for replication process.

Hence, the correct asnwer is "Helicase".
