<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:
B. a substance that can donate an H+ ion
Explanation:
Answer:
A homozygous dominant brown mouse is crossed with a heterozygous brown mouse
B= brown mouse
b= black mouse
Bb= heterozygous brown mouse
Bb x Bb= BB, Bb, Bb, and bb 3:1 genotype
phenotype with 3 brown mouse and 1 black mouse offspring
Explanation:
Answer:
Shivering thermogenesis.
Explanation:
The rate of heat production is increased by increasing muscle contraction by movement is shivering thermogenesis because nerve impulses are transmitted to the skeletal muscles by the hypothalamus which will result to contractions that will produce heat.
Shivering thermogenesis is Contraction-mediated heat production High intensity shivering activates large muscles and produce more glycolysis which is then use as the main source for heat production
16-7= 9 you subtract the atomic number from the mass and get the number of neutrons so there ae 7 protons and 9 neutrons
