Energy must flow through autotrophs because they take the energy from the sun, then herbivores feed off the autotrophs converting energy from the plant into energy that they can use. Carnivores then feed off the herbivores, and finally carnivores feed off of each other, and the process starts over again. Heterotrophs only generate a small fraction of their energy through photosynthesis, making autotrophs very important.
Answer: B
Explanation: There’s no picture.
Answer:
1/2
Explanation:
The allele for the red-green color blindness is X-linked recessive. The father of the woman was colorblind (X^cY) which means that the woman is a carrier for the allele and has genotype (X^cX). The genotype of the colorblind male would be X^cY. A cross between a carrier woman and a color-blind man would produce progeny in following ratio= 1/2 colorblind daughter: 1/2 normal daughter: 1/2 colorblind son: 1/2 normal son.
Therefore, there is a 50% probability that their first son is colorblind.
