During an ethylene signalling pathway, what will have done inside cytosol and nucleus . Given below some
prediction about presence and absence of ethylene in column B match with column
A
|
COLUMN A |
COLUMN B |
|
I- In the presence of ethylene |
a) ETR1 signaling is repressed and CTR1 is
inactive |
|
II-
In the absence of ethylene |
b) ETR1 activate CTR1, a Ser/Thr kinase |
|
|
c) CTR1 phosphorylates the C-terminal domain
of EIN2 |
|
|
d) The nonphosphorylated C terminus of EIN2 is
cleaved by a protease |
|
|
e) Phosphorylation of EIN2 inhibits
proteolytic cleavage |
|
|
f) EIN3 transcription factors are
ubiquitinated and degraded in the nucleus by the 26S proteasome |
|
|
g) EIN3 initiates a transcriptional cascade by
activating expression of ethylene-responsive genes, including ERF1
transcription factor, leading to ethylene responses |

The graph below shows the growth rates of populations of bacteria that have evolved for many generations at different culture temperatures (25°C, 30°C, and 35°C). Each population grows over only a limited range of temperatures (its thermal niche), which are bounded by its critical thermal limits. Within this range, growth rate increases with temperature up to a maximal value and then declines rapidly with increasing temperature. Growth rates are known to be the major determinant of fitness for these bacteria.
If all three populations were mixed together and placed at 37°C, which of the following would be most likely to happen?
