The best answer is Hormone.
Hormones are chemicals secreted by one tissue and affect the functioning of other tissues and cells.
Hormones are secreted by glands of the endocrine system. They are secreted into the blood and also extracellular fluid. They then circulate in the blood and come into contact with essential all cells, but a specific hormone will only affect a limited number of cells, namely the cells that bear a receptor for that hormone.
Red blood cells for example have receptors for the insulin hormone that is produced by the pancreas. They will therefore be directly affected by insulin while all other cells in the blood remain oblivious of this hormone..
Some factories drain chemicals into the local water supply. Some factories also release smoke and chemicals into the air.
Answer:
1. b. The reaction rate will remain steady over the entire 8 minutes.
2. c. The reaction rate approach zero before 8 minutes.
3. a. The reaction rate will be close to zero over the entire 8 minutes.
4. b. The reaction rate will remain steady over the entire 8 minutes.
Explanation:
When 0.5 mL of enzyme is introduced with water, the reaction will remain steady. When more substrate solution is mixed with water, then reaction will approach to zero depending on the amount of substrate mixed with water.
A)
It is possible to obseve that the fur color of the feline is connected with the male chromosome "X". The presence of Xb (recessive) and XB (dominant) results in the tortoise color.
The ausent tail T is carried in the autosomes with a dominacy over the presence of tail "t" and the presence of both dominances "TT" results in the death of the offspring.
B) Genotypes of the parents:
Male: XbY, Tt
Female: XBXb, Tt
