Which of the following describes what happens in the second step of photosynthesis? a. electrons bond hydrogen atoms to oxygen molecules to form a carbohydrate molecule. b. electrons bond hydrogen atoms to carbon dioxide molecules to form a carbohydrate molecule. c. electrons bond hydrogen atoms to carbon monoxide atoms to form a carbohydrate molecule. d. electrons bond hydrogen atoms to carbon dioxide atoms to form a carbohydrate molecule.

B. Electrons bond hydrogen atoms to carbon dioxide molecules to form a carbohydrate molecule.

Explanation:

In the second step of photosynthesis electrons bond hydrogen atoms to carbon dioxide molecules to form a carbohydrate molecule.

The second phase of photosynthesis takes place in the stroma. Six carbon dioxide molecules enter the cycle and bond with hydrogen atoms to produce one molecule of glucose or sugar.

gregor john mendel is known for study of inheritance in pea plants. he used garden pea plant for his study, having alternative traits for various characters. he performed cross-breeding in pea plants to check how characters are transmitted between parents to offspring, such as cross between pure tall and pure dwarf plant. mendel studied the inheritance patterns in pea plants for various generations.

thus, the correct answer includes options and f).
