Explanation:
Chromosomal deletion is the loss of genetic code, caused by a segment of chromosome breaking away during DNA replication. The best answer is the third one, "when part of a chromosome breaks off and does not reattach."
Answer:
02.5 N
Explanation:
02.5 N is a derived unit of measurement.
A derived unit is one that is obtained by combining two or more fundamental units.
Force = mass x acceleration
The unit of mass = kg
acceleration = m/s²
Combining the two; kg x m/s² = kgms²
1N = 1 kgms²
kg, m, k and N are fundamental particles
The Mitral valve which is also known as left atrioventricular prevents blood movement from left ventricle to left atrium.
Explanation:
- Human heart is four chambered.
- Two of these are receiving chambers known as atria and the other two are distributing chamber known as Ventricles.
- Atria are superior chambers and ventricles are inferior chambers.
- The heart has four valves broadly grouped as Atrioventricular valves and Semi lunar valves.
- Atrioventricular valves allows flow of blood from atria to ventricle. These are tricuspid valve and bicuspid valve.
- Semi-lunar valves allow blood to pass out of the heart. These include the pulmonary and aortic valves.
- The pulmonary valve allows blood to flow from right ventricle to the heart while aortic valve allows blood to flow from left ventricle to the Aorta.
- The Tricuspid valve located between the right atrium and right ventricle allows blood to flow from right atrium to the right ventricle.
- The Bicuspid valve ( Mitral valve) located between the left atrium and left ventricle allows the blood flow from left atria to left ventricle.
- Valves maintain the unidirectional flow of blood and thus prevent its back flow.
