Answer:
look in textbook - concept 29.6
Explanation:
Drought stress can also cause stomata to close. A hormone called abscisic acid (ABA) is produced in roots and leaves in response to water deficiency and signals guard cells to close stomata. This response reduces wilting but also restricts CO2 absorption, thereby slowing photosynthesis. ABA also directly inhibits photosynthesis. Water availability is so tied to plant productivity not because water is needed as a substrate in photosynthesis but because freely available water allows plants to keep stomata open and take up more CO2.
abscisic acid (ABA): A plant hormone that slows growth, often antagonizing the actions of growth hormones. Two of its many effects are to promote seed dormancy and facilitate drought tolerance.
It seems that you have missed the necessary details and options for us to answer this question so I had to look for it. Anyway, based on the given description above, the molecule which is considered the "gas" that powers a cell's "engine" is called the Adenosine Triphosphate or ATP. Hope this helps.
Answer:
d) alternating sugars and phosphates.
Explanation:
DNA is a molecule which acts as the genetic material of the organisms on Earth. The DNA is made of the monomer units called nucleotides which are composed of a sugar called deoxyribose, a phosphate group and two types of nitrogenous bases (purines and pyrimidines).
The DNA structure is known as the double-helical model which gives a ladder-like appearance in a twisted manner. The backbone of the ladder or DNA is made of the deoxyribose sugar and the phosphate group whereas the nitrogenous bases are arranged inside the DNA.
Thus, option-D is the correct answer.
