The question is incomplete, so the complete question is as follows:
A chloroplast has stopped producing ATP and NADPH. Which of the following is most likely causing this?
a.The chloroplast has used up its supply of chlorophyll molecules.
b.Electrons have stopped moving through the electron transport chain.
c.The sun has risen and the chloroplast now can make more chlorophyll.
Answer:
b.Electrons have stopped moving through the electron transport chain.
Explanation:
ATP and NADPH are produced in the light dependent reaction stage of the photosynthesis that occurs within chloroplast grana.
ATP and NADPH are produced due to the movement of electron and proton (H+) in the electron transport chain, so if the movement of electrons will stopped in the electron transport chain, the formation of ATP and NADPH will also get stop.
Hence, the correct answer is "b".
Answer:
Adding a lake near any town will most likely increase rainfall because of the added water, and water vapor levels will also increase. Because of the excess water in the environment, more water will be found in the surrounding atmosphere (the same reason precipitation will increase in the area.)
Three of the major characteristics used to classify organisms are cell structure, mode of nutrition and cellularity. These characteristics help scientists determine how organisms are similar to each other as well as how they are different from each other.
Answer:
Acid rain refers to the rain which acidic in nature having a form of precipitation and elevated levels of hydrogen ions (low pH). The normal pH of rain is around 5.6
Rising concentration of Sulfur dioxide (SO2) and nitrogen oxides (NOx) in atmosphere is one of the cause of acid rain. Sulfur dioxide (SO2) and nitrogen oxides (NOx) are released by vehicles, fossil-fuel power plants and oil refineries.
When a sulfur dioxide and nitrogen oxides released in air they mix with oxygen, water and other chemicals in the air and form sulfuric and nitric acids. sulfuric and nitric acids mix with precipitation and its pH level is about 5.2 or below.
Hence, rising concentration of SO2 And NO2x is one of the biggest reason of acid which damages agriculture, buildings and wildlife et-cetra.
Answer:Adhesion
Explanation:Is the attraction of water molecules to other molecules of different substances. Water molecules are said to be polar which means that the molecule has a slightly negative charge and a slightly positive charge. This property of water allows it to interact with other polar or charges substances making it attract to other molecules.
