Crossing over occurs at the four-strand stage when two homologous chromosomes, each consisting of a pair of sister chromatids, are paired. Each crossover involves just two of the four strands and generates two recombinant strands.

A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
Answer:
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Answer:Primary succession occurs on land that is new and has never had a flora and fauna example: glacier retreats, lava flows. Secondary succession occurs on land that has been cleared example: by fire, of flora and fauna, but which still has viable seeds and spores in the soil.
