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.
I believe that the best answer for this question is false. The individual who was the first to describe microbes was Antonie van Leeukwenhoek. He is considered to be the Father of Microbiology and the first microbiologist. Hook was actually his contemporary. I hope this helps.
<h2>Regulate of Environmental</h2>
Explanation:
- The motivator based administrative methodology progresses in the direction of forestalling ecological issues by giving promptings to urge contaminating substances to diminish contamination.
- An advantage of the motivator based methodology is that it energizes the production of imaginative and financially savvy techniques for <em>contamination control. </em>
- Administrative methodologies require government offices to limit or direct the exercises of controlled gatherings utilizing terms and conditions inside statutory and administrative instruments, <em>working grants, licenses, endorsements or codes of training. </em>
- <em>Command and control causes administrators to benefit as much as possible from whatever hardware they have - individuals, data, material, and, regularly generally significant of all, time. </em>
- Particles have assisted with securing nature, they have three weaknesses.
- <em>They give no motivating force to going past the cutoff points they set.
</em>
- They offer restricted adaptability on where and how to lessen contamination.
- <em>They regularly have politically-spurred escape clauses.</em>

The most painfull effect resulting from loss of insect species globally would likely be a drop in crop pollination.
<h3>What do you mean by pollination?</h3>
Pollination is the act of moving pollen grains from the male anther of a flower to the female stigma. The goal of every living organism, contains plants, is to create offspring for the next generation. One of the ways that plants can make offspring is by creating seeds.
Thus, option "B" is correct, The most painfull effect resulting from loss of insect species globally would likely be a drop in crop pollination.
