In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of
ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.

Según la historia evolutiva y sus diferentes saltos, ¿Qué linaje de especies es más antiguo?
Arturiano [62]

es la A

Hace aproximadamente 250 millones de años ocurrió la extinción masiva del Pérmico-Triásico, un evento en el cual murieron hasta el 96 por ciento de las especies marinas y un porcentaje similar de las terrestres. Cerca de tres millones de años después se produjo la separación, a partir de un ancestro en común, de los linajes que con el tiempo darían origen a las aves y los cocodrilos. El grupo que incluye tanto a cocodrilos como aves se lo denomina Archosauria, que significa ‘reptiles dominantes’.
