➜ <u>Mendel conducted breeding experiments with garden peas</u>:
[i] He studied plants (pure) of a tall/short varities.
[ii] He crossed them and obtained F1 progeny.
[iii] He found that F1 progeny was all tall plants.
[iv] He selfed the (hybrid) plants if F1 progeny.
[v] He found that in F2 progeny there were tall as well as short plants.
[vi] The three quarter plants were tall and one quarter was short.
(or any other contrasting character may be taken).
<u>Note</u>: Here, F1 means <u>First fillial generation</u> and F2 means <u>Second fillial generation</u>.
Well-sorted sediments have grains of similar size, and are the result of much sediment transport and earth processes which segregated the sediment by depositing different size fractions in different places.
Answer:
The egg contains both food and mitochondria in addition to its vital DNA, thats why it is much larger. The sperm cell has to be much smaller than the egg cell, because it is the one that swims. If a sperm cell were as big as an egg, it would not be able to move very fast nor very far.
Answer: Decomposers
Because, when organisms are broken down and decomposed, they are mixed in with the soil. Yes, you should add soil to a food web that depicts the food relationship in an ecosystem because not only is it a result of decomposition, it helps the producers grow, starting the food chain again.
When oxygen is absent, anaerobic respiration occurs ('an' means without).
