The Griffith's experiment, the Avery-MacLeod-McCarty experiment, and the Hershey–Chase experiments were the set of experiments that established DNA as the key hereditary molecule. The Avery-MacLeod-McCarty experiment was an extension to the Griffith's experiment. The heat killed virulent S strain cells of the Griffith's experiment were lysed to form a supernatant containing a mix of RNA, DNA, proteins and lipids from the cell. The supernatent was equally divided into 3 parts after the removal of the lipids. The 3 parts were respectively treated with an RNAase to degrade the RNA, DNAase to degrade the DNA and proteinase to degrade the proteins. The treated supernatant was then added into the culture containing the non-virulent R cells. In case of the supernatant treated with the DNAse, no transformation of R cells into S cells occurred. The transformation of R cells to S cells occurred in the proteinase and the RNAse cases. This indicated that DNA was the hereditary molecule and not protein or RNA.

Answer:
Aerobic respiration;this is the process of breaking down of glucose <u>with Oxygen</u> to generate energy as ATPs in living cells
Location- Matrix and inner membranes of mitochondria
Energy source_oxidative phosphorylation of glucose
Waste product-water( oxygen accept the final electron to form water)
.
38 ATPs from 1 glucose molecule
Explanation:
Photosynthesis; this is the process of reducing C02 with hydrogen ion, from water i<u>n the presence of sunlight , enzymes and green pigment chlorophyll</u> to form <u>glucose</u>
Location- stroma and thylakoid membranes of chloroplast
Energy source-photo-phosphorylation(sunlight)
Waste product-Oxygen
18ATPs
Answer: D.) Plant D
Explanation: A control group is composed of the test subject(s) that do not receive any experimental treatment. In this case, Plant D is the control group because it does not listen to any music unlike the rest of the plants.
The lower respiratory tract is sometimes referred to as the tracheobronchial tree, this describes the branching structure of airways supplying air to the lungs, this includes the trachea, bronchi and bronchioles.
a. 25%
b.75%
c. 50%
d. Male cats have only one X chromosome in their DNA meaning that they should be unable to inherit different colours.
