vitfil [10]

Answer:

The correct answer is -

Decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

NO effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

Increase plant growth - increase CO2, increase sunlight, increase H2O

Explanation:

Decrease in exposure of sunlight to the plant or less intense light will affect the production of oxygen and glucose negatively which affect the growth of the plant. Decrease CO2 will be affect the growth of the plant similarly as light and water molecules which is decreased in plant growth.

Increase in the in production of the products which are 02, glucose, will have no effect in plant growth though increase in the carbon dioxide, water, and sunlight will positively affect plant growth.

Thus, the correct answer is - decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

no effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

increase plant growth - increase CO2, increase sunlight, increase H2O

Two protein kinases, K1 and K2, function sequentially in an intracellular signaling pathway. If either kinase contains a mutatio
Korolek [52]

Answer:

The order must be K2→K1, since the permanently active K1 allele (K1a) is able to propagate the signal onward even when its upstream activator K2 is inactive (K2i). The reverse order would have resulted in a failure to signal (K1a→K2i), since the permanently active K1a kinase would be attempting to activate a dead K2i kinase.

Explanation:

  • You characterize a double mutant cell that contains K2 with type I mutation and K1 with type II mutation.
  • You observe that the response is seen even when no extracellular signal is provided.
  • In the normal pathway, i f K1 activat es K2, we expect t his combinat ion of two m utants to show no  response with or without ext racell ular signal. This is because no matt er how active K1 i s, it would be unable to  act ivate a mutant K2 that i s an activit y defi cient. If we reverse the order, K2 activating K1, the above  observati on is valid. Therefore, in the normal signaling pathway, K2 activates K1.
