A loss-of-function mutant in the gene encoding Mad2.
Answer:
Both have two circuits for circulation.
Explanation:
- The two circuits of circulations are known as the systemic circuit and the pulmonary circuit.
- In the<u> systemic circuit</u> oxygenated blood from the heart is pumped to all parts of the body through the blood vessels and then the blood is pumped back to he heart.
- In the<u> pulmonary circuit</u> deoxygenated blood from all parts of the body is pumped from the heart to the lungs to be oxygenated and after it is oxygenated it is pumped back to the heart.
Answer and Explanation:
The cell was placed in a hypertonic solution. Glucose is a monosaccharide while starch is a polysaccharide. The concentration on the outside is higher compared to that on the inside. The cells have cell membrane that is semi-permeable.
Movement of molecules is dependent on the concentation gradient. However, the size of molecules determine the diffusion rate. Small and light molecules diffuse faster than large and heavy molecules thus glucose diffused faster than starch.
The cell membrane being permeable suggested that it allows molecules of small sizes to pass but not large ones.
Acetylcholine receptor locales are blocked. Acetylcholine receptors are found on the surface of muscle cells, moved in the neurotransmitter between nerve cells and muscle cells. It is ligand-gated particle channels, and, as different individuals from the "Cys-circle" ligand-gated particle channel superfamily, are made out of five protein subunits symmetrically organized like fights around a barrel.
