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.
It is safe to assume that the eastern kingbird will have a <u>type 2 </u><u>functional response </u><u>to an increase in </u><u>prey abundance</u><u>.</u>
The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:
- Type 1: An increase in consumption
- Type 2: A decrease in consumption
- Type 3: Decreased consumption, followed by a quick increase.
The Eastern kingbird is likely to follow a <u>type 1 </u><u>functional response</u> to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.

Answer:
10 H atoms combine with 5 oxygen to form 5 water molecules.
Explanation:
those substances which having low boiling point or low melting point such as water they form covalent bond.
Covalent bonds form between non-metal atoms. Each bond consists of a shared pair of electrons, and is very strong. Simple molecular substances and giant covalent structures have different properties.
