Answer:
BB is blue
bb is red
Bb is patchwork
Explanation:
It can't really be codominant since lowercase letters are recessive, and condomance needs 2 dominant alleles of a different types. So really it should be BB for blue, RR for red and BR for patchwork...
The one advantage of using DNS assay to detect maltose production is the formation of a soluble and colored product compound.
The reaction that occurs between maltose and DNS in the assay is a redox reaction (reduction and oxidation) such that maltose gets oxidized and becomes Maltonic Acid while the DNS gets reduced into reduced DNS. The intensity of orange/brown /red color of reduced DNS is proportionately related to the amount of Maltose in the solution.
Answer:
When you sit on a plane for 6 hours without moving, blood accumulates in your veins, and the moment you get up, gravitational forces affect venous return, cardiac output, blood pressure, and venous pressure. That way, when you're sitting on a plane, the gravitational force is the same at the upper and lower extremities, such as the chest, abdomen, and legs, causing venous blood pressure and volume to be evenly distributed throughout the body. However, when one gets up, one becomes dizzy because of abnormal regulation of blood pressure. This is because gravity causes blood to accumulate in the lower extremities (veins of the legs and trunk). This lowers the blood pressure and the blood that the heart pumps. By causing blood to accumulate in the lower extremities, and as venous compliance increases, the veins expand with blood that causes the volume of blood to shift in the veins. This increases the volume and venous pressure in the lower extremities when standing. And the volume of thoracic venous blood is less and less central venous pressure. This leads to a decline in stroke volume. Cardiac output and mean arterial pressure also decrease as left ventricular stroke volume decreases, reducing pulmonary venous return. Decreased standing blood pressure, referred to as orthostatic or postural hypotension. Thus, lowering blood pressure decreases cerebral blood flow, which means less range of blood in the brain causing dizziness.

Answer:
Option (2).
Explanation:
Ecological succession is the change in the ecological community of the species with respect to time. Two types of the succession are secondary succession and primary succession.
The ecological succession includes various transitional stages before reaching to the climax community. The simple species acquires first and then the climax species is reached at the end of the succession. Different changes are involved in the formation of climax community.
Thus, the correct answer is option (2).
