CAN YOU EXPLAIN IT? The flowers in the photo are all the same species-50 why don't they all look exactly the
same? Now, think about all the different people you know. Everyone looks different. Even
siblings with the same parents often look different from each other and their parents.
Variation, such as flower color, ear shapes, or type of fur occurs in organisms in different
ways. How does this happen?
PREDICT How do you think characteristics such as flower color, ear shape, or hair type
are determined in different organisms?

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

the answer is sex-linked recessive.
