d. scientific theory
Explanation:
The statement that all living things like planktons are made up of cells is a true scientific theory.
All living organisms are made up of cells and all cells are derived from pre-existing cells is the first and most fundamental postulate of the cell theory.
- the concept that living things are made up of cell is from the cell theory.
- the cell is the fundamental unit of life.
- the cell theory provides an explanation into cells as the unit of life

Answer:
It adjusts to different oxygen levels.
The cytochrome bo branch operates when E coli is growing rapidly with good aeration.
The cytochrome bd branch operates at low oxygen conditions. It is located in the outer membrane.
Explanation:
Electron transport chains of Escherichia coli are composed of different dehydrogenase and terminal reductase which is linked by quinones. It adjusts to different oxygen level because Oxygen is preferred electron acceptor and represses the terminal reductase of anaerobic.

Answer:
During cellular respiration glucose is broken down in the presence of oxygen to produce carbon dioxide and water.
Explanation:
Answer: Fruit will not brown. Browning requires a functional enzyme.
Explanation:
Genetic engineering refers to the manipulation of an organism's genes. Scientists use a variety of molecular tools and techniques to cut up and join genetic material from different species and to introduce this new hybrid DNA into another organisms. <u>The overall goal is to add or remove an organism's genetic makeup for the better, or to transfer DNA code from one species into the other, in order to form new combinations or heritable genetic material.</u>
Enzymatic browning is a reaction that occurs in fruits which results in negative effects on characteristics such as taste, color, and nutritional value. This reaction is a caused by phenolic compounds' oxidation by an enzyme called polyphenol oxidase, which causes the generation of dark pigments. This is often seen in apples which are rich in this enzymes and susceptible to this enzymatic browning.
If through genetic engineering, the gene encoding the enzyme responsible for the apple browing is removed, then this enzyme cannot be produced by the apple. Consequently, apples will not brown<u>,</u> because there will not be a polyphenol oxidase that oxidates the phenolic compounds.
