A certain type of frog reproduces sexually and has 36 pairs of chromosomes in each of its body cells. How many chromosomes are in each of the frog’s sex cells? A. 9
B. 18
C. 36
D. 72

Once again I'm here to prove the top one is correct.

Explanation:

Some 95% of frog species examined to-date, including Xenopus, the current model frog, possess homomorphic sex chromosomes 67, 68. Why and how sex chromosome homomorphism is maintained in so many species of this (often evolutionarily ancient) group is a mystery.

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

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.
