What is the first step of the calvin-benson cycle?
atp and nadph combine to make g3p.
g3p is used to make glucose and other
compounds.
atp and g3p combine to make rubp.
carbon dioxide and rubp combine to make pga.

In stage 1., the enzyme RuBisCO incorporates carbon dioxide into an organic molecule, 3-PGA.

as the gila monster consumes the eggs or young of the desert cottontail and gambel's quail, thus its main food supply is only accessible for a restricted time duration every year. however, for this, the gila monsters exhibit three adaptations, which elevate their survival rate in the desert condition.  

first, is that they possess huge bodies, and can consume greater concentrations of food during a small period. secondly, they require to feed infrequently as they can accumulate fat in their tails. ultimately, their rate of metabolism is very low, so that they can burn their reservoirs of fat gradually.  

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
