They form hydrogen bonds with the water cells so therefore strengthen the cell membrane. Hope this helped
Generally, mutations result in reduced protein function or no protein function. A mutation with reduced function is called a leaky mutation because some of the wild-type function “leaks” through into the phenotype. A mutation that results in no protein function is called a null mutation
Answer:
False
Explanation:
The most specific feature of cardiac muscles is the presence of intercalated discs. Intercalated disc connects the ends of cardiac muscle fibers to one another. The discs have desmosomes and gap junctions. The function of desmosomes is to hold the cardiac fibers together. The gap junctions of cardiac fibers allow muscle action potentials to spread from one cardiac muscle fiber to another. These gap junctions have tubular connexons that form channels and connect the cytosol of adjacent cardiocytes to allow the flow of ions and spread of action potential from one cell to another.
Answer:
pulmonary circuit, systemic circuit
Explanation:
The circulatory system consists of 2 circuits -
pulmonary circuit
systemic circuit.
The pulmonary circuit carries deoxygenated blood. The right auricle receives the impure blood by superior and inferior vena cava, then the blood enters the right ventricle. From the right ventricle, the deoxygenated blood moves to the lungs by the pulmonary artery.
In the lungs, the deoxygenated blood gets oxygenated and enters the left ventricle through pulmonary veins. The pureblood then passes into the left ventricle and then the ventricle pumps the oxygenated blood to different parts of the body. This blood passes to the body aways from the heart by aorta. When the blood gets deoxygenated, it again enters the right auricle. In this way, double circulation occurs and both types of blood do not mix together.
