I think it might be B.) and C.)
By the law of conservation of energy, the energy input to a system must equal the output. However, when there are more moving parts in a machine, like in a complex machine, the energy converted to non-useful energy, such as the production of heat energy via friction, is increased. Therefore, the more the moving parts, the greater the losses of energy due to increased friction. This is why complex machines are less efficient.
The statement is true.
<u>Explanation:</u>
A product line is a gathering of related items all showcased under a solitary brand name that is sold by a similar organization. Organizations sell different product offerings under their different image names, looking to separate them from one another for better ease of use for purchasers.
If an unprofitable product is eliminated from the product line, it will effect the rest of the products in the line and will increase the earning of the other products in the line.
The start codon is the first codon of a messenger RNA (mRNA) transcript translated by a ribosome.
Nitrogen base sequence for the start codon is AUG.
Answer:
Robert Koch
Explanation:
Robert Koch injected extract from infected animals into healthy mice. This resulted in the development of anthrax in mice. He incubated a part of the spleen containing the anthrax bacillus in beef serum. This allowed the growth and production of endospores by the bacteria.
He isolated the bacilli and the spores and injected into healthy mice. This caused the development of anthrax mice, He concluded that anthrax is caused by a bacterium. He correlated different types of microorganisms with a particular disease and developed Koch’s postulates.
According to these postulates, all the diseased living beings should have the respective causative microorganism. The same must not be present in healthy organisms. isolation of causative microbes must be followed by the development of their pure culture.
