I think it’s 2, because in order to do photosynthesis you must have chloroplasts so all photosynthetic organisms have to have chloroplasts
Answer: The Calvin Cycle
Explanation: The Calvin cycle involves the reduction of carbon( in this case CO2) to carbohydrates. This process requires reduction power and chemical energy which is provided by NADPH and ATP respectively, both generated from the light reaction. Thus, it is the Calvin cycle that produces sugar but it can do so only with the help of NADPH and ATP. The metabolic steps of the Calvin cycle are sometimes referred to as “dark reaction” because none of the steps requires light directly. Nevertheless, the Calvin cycle in most plants occurs during daylight, for only then can the light reaction regenerate NADPH and ATP spent in the reduction of CO2 to sugar.
The air which is oxygen ( H^2 o) helps the organisms procreate.
To perform active transport, cells use ATP
Answer:
<h2>Incomplete dominance</h2>
Explanation:
As given here;
Two pure line of four-o'clock plant, one having red flower and other having white flower, when they are crossed, they produce all pink progeny.
So, lets red as RR and white as rr
Cross between RR and rr
Here all offspring are Rr ( Pink ).
It's the result of incomplete dominance, in complete dominance the offspring is the intermediate of both the parents.
F2 generation:
As cross between Rr and Rr
progeny are: RR, Rr, Rr, rr
RR =red
Rr= pink
rr= white
So, red: pink: white = 25:50:25
