Biology
1 answer:
faust18 [17]2 years ago
4 0

non-disjunction is a pathological event that occurs during the second anaphase in meiosis when sister chromatids are not separated. As a result one of the resulting cells will have 1 extra chromosome and the other will be 1 short. An example of a non-disjunction that can occur in humans is Down syndrome that has a frequency of about 1/1000 people. It is caused by the non-disjunction of the 21st pair of chromosomes.

GREYUIT [131]

Answer:

glucose is the food for producers. they make their own food with the photonic energy from the sun. this energy is then passed to primart consumer, then secondary consumers, then tertiary consumers. energy decreases as it climbs the food pyramid. only 10 percent of the previous tier is carried onto the next tier.

for example if plants had 10,000 kilocalories, grasshoppers would get 1,000 kilocalories,

frogs would get 100 kilocalories,

and snakes would get 10 kilocalories.

kilocalories are a unit of energy.

i hope this helped! have a nice day
