lana [24]

Answer:

The correct answer is -transfer fixed carbon dioxide to cells in which the Calvin cycle occurs

Explanation:

In C4 plants the light reaction and Calvin cycle occurs in two different cell that are mesophyll cell and bundle sheath cells. First, the CO₂ is fixed into 4- carbon oxaloacetate by an enzyme PEP carboxylase.  

Then this oxaloacetate is converted into a simpler form called malate. Malate molecule then enters into bundle sheet cell and there it releases one molecule of CO₂. This CO₂ enters the Calvin cycle which results in the sugar formation with the help of enzyme rubisco.

Therefore by releasing of CO₂ molecule by malate in bundle sheet cells, it transfer fixed carbon for the Calvin cycle to occur.

OKEASE HELP WILL GIVE BRAINLIEST
Keith_Richards [23]

The correct answer is: A. the same traits

Homologous chromosomes come in pair: one inherited from the mother and one inherited from the father. They have the same genes in the same loci, meaning that those genes code for the same traits. But, variants of those genes-alleles can be different e.g. one recessive one dominant). During the meiosis (cell division of gametes) homologous chromosomes align correctly with each other before separation.

Thank You!
