I think 1) B I don't know what 2 is but it isn't A or B it is between C or D
The powerhouse of the cell: That is a term used to describe the MITOCHONDRIA, because its main function it to produce energy for cellular activities.
Mitochondria is the host of cellular respiration. This is where the Mitochondria take in glucose and oxygen to produce energy and is distributed all throughout the body as energy-rich molecules of ATP.
Answer: The correct answer for the fill in the blank is A) Zero.
According to Mendel's law of dominance, in a cross between parents that are true breeding for a contrasting trait (like plant with pure purple and white flowers), only one form is expressed in the next generation and that form is called dominant trait.
As per the Mendelian inheritance, purple flower color is dominant over white flower color. When parents that are pure breeding for purple and white flower ( PP and pp) are crossed, they will produce all purple flowers ( Pp) in the first generation as purple is dominant trait.
Thus, percent of offsprings with white flowers is zero.
The Answer is C. DNA
Our DNA is responsible to carriy out our genetic information which located in our cell nucleus.
The Scientist previously thought the molecul of inheritance is composed of Lipids (some sort of proteins)
As for RNA, it only carried out genetic information in a couple of viruses. Even most viruses use DNa to carry out its genetic information
