Answer:Gene regulation by attentuation would not be possible if transcription and translation were not coupled in bacteria.
Explanation:
The question is incomplete as it does not have the answer which are:
A) They do not participate in the Calvin cycle.
B) They use PEP carboxylase to initially fix CO2.
C) They conserve water more efficiently.
D) They exclude oxygen from their tissues.
Answer:
They use PEP carboxylase to initially fix CO2.
Explanation:
Photorespiration is a wasteful process in plants which produces less amount of ATP and low glucose level as the RUBISCO enzyme binds with the oxygen instead of Carbon dioxide.
The Rubisco enzyme binds with the carbon dioxide usually during the Calvin cycle but in hot and dry conditions it binds the oxygen.
So to avoid the photorespiration, plants evolved adaptive features in the anatomy of the leaf that is they separated the photosynthetic steps by forming wreath-like structure around the vascular bundles called Kranz anatomy.
Instead of Rubisco, PEP carboxylase binds the carbon dioxide, convert it to malate and then transport it to bundle sheath cell where the Calvin cycle takes place as malate provide Carbon dioxide gas to Rubisco enzyme.
Thus, the selected option is correct.
Heat moves in the direction from hot to cold
It is b:<span>to prevent drying out and to lay their eggs

Two atoms are held together by an ionic bond when an electron transfers from one atom to another atom to produce ions of different charges, which would attract and form a crystalline type of structure known as an ionic lattice.
