<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
Answer:
Because ovalbumin is <u>denaturated</u>.
Explanation:
When a protein is heated, <u>denaturation</u> occurs. This is a process in which the protein loses its conformation and structure, so we can observe changes in color and viscosity. Before heating, egg white is clear, traslucent and runny. When heated, it turned opaque, in a solid state. This changes indicate that the protein ovalbumin has been denaturated, so it changes its structure and properties.
Answer:
The average density of deer in 1923 was 1 deer per 8 acres
Explanation:
Given -
In 1923, the population of deer rose to 
The density of any species is equal to total population divided by total area of the land in which this population is residing.
Where d represents the density
P represents the population and
A represents the area of land
Substituting the given values in above equation, we get -
Thus, the average density of deer in 1923 was 1 deer per 8 acres
As demonstrated by long-range mapping of restriction endonuclease recognition sequences and genomic cloning, we found that the human genes encoding interleukin 3 (IL 3) and granulocyte/macrophage colony-stimulating factor (GM-CSF) are tandemly arrayed on the long arm of chromosome 5, separated by 9 kilobases (kb) of DNA. This close physical linkage of genes with similar structure and biologic function suggests that these cytokines may have evolved from a common ancestral gene. This linkage in evolution of two relatively divergent genes further implies that some of the other lymphokine and cytokine genes that appear to share as much or more sequence similarity than do IL 3 and GM-CSF may be distantly related members of a cytokine gene family.
Answer:
Uracil
Explanation:
Like DNA, RNA is made up of nucleotides called ribonucleotides. However, unlike DNA, RNA contains the sugar ribose instead of deoxyribose and the base uracil instead of thymine. RNA also contains of only one polynucleotide chain. Uracil is a type of nitrogenous base that is replaced by thymine during the formation of RNA.
