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.

1. Give four (4) importance of “wind”?
KengaRu [80]

Answer:

1. Wind is an important element when it comes to current weather and predicting future forecasts. Wind transports moisture and temperature from one area to another, therefore weather conditions change with the shift of wind direction.

2.All plants and animals, including humans, are exposed to the dangers of solar UV radiation; it can cause significant damage to plants, as seen in crop yield reduction and leaf burn, and can damage animal skin health.

3.sun-light is a key energy source for all plants. Through a process called photosynthesis, plants absorb energy from the sun, which fuels the processes necessary for survival.

4.The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth.
