Answer:
B
Explanation:
I'm pretty sure that's the answer because the others seem very odd for a population scale when a new pipe is inserted.
Answer:
The mean weight of the progeny is 
grams
Explanation:
Given -
Mean fruit weight of tomato plant (M1) 
g
Narrow sense heritability (h2) 
g
Mean weight of tomato plant selected for artificial selection (M0) 
g
Substituting the given values in above equation, we get -
The mean weight of the progeny is grams
The correct answer is (C) biomass at each trophic level
Pyramid of energy is a graphic representation of amount of energy trapped per unit time and area in different trophic levels of a food chain with producers forming the base and top carnivores the tip. As the biomass of producers are always greater than the carnivores, the pyramid of energy can't be inverted.
Answer:
A XY or XY gamete fuses with a normal gamete (X or Y)
Explanation:
Meiotic nondisjunction is the phenomenon whereby chromosomes fail to separate during meiosis I or II. Meiotic nondisjunction leads to the formation of abnormal gametes I.e. gametes with additional or missing chromosomal piece.
The fusion of these abnormal gametes produced by nondisijuction with a normal gamete (X or Y chromosome). This leads to a condition called ANEUPLOIDY, which is a chromosomal disorder. In the case od Calix, XXY is an ANEUPLOIDY state that could have resulted because there was a fusion between a XX gamete and Y gamete or XY and X. The XY or XX gametes are produced as a result of nondisijuction.
