Answer:D
Explanation:All things are made up of atoms but only living things are made of cells.
B) X or Y chromosomes, inherited from your mother.
C) two of the 22 pairs of chromosomes your inherited.
D) chromosomes from your mother and X from your father.
Answer:
The correct answer would be option A.
In humans, the gender of a child is mainly determined by the sex chromosome inherited from the father.
It is because human females are homozygous (XX) in terms of sex chromosome. So, their gamete will always contain an X chromosome.
In contrast, human males are heterozygous, that is, they contain XY as sex chromosome. Thus, they will produce two types of gametes of which one would contain X and the other one would contain Y.
When the male gamete containing X chromosome fuse with female gamete, the offspring produce would be a girl and when the male gamete containing Y chromosome fuse with female gamete, the offspring produce would be a boy.

10%
Explanation:
Only 10% of the energy absorbed by plants from the sun is passed to primary producers and converted to biomass. Similarly, only 10% of the energy fro primary producers is passed to secondary producers, and this continues up teh chain to Quaternary consumers. This is why energy of an ecosystem is represented as a pyramid (tapering at the top). Transfer of energy up an ecosystem is very inefficient with most of the energy lost to the environment as heat during the transfer. In this case, the oak tree is a primary producer which represents the base of the energy pyramid.
