Good evening, Pineappleman!! Your best answer would be D - Some bacteria are beneficial to human health because it talks about how it helps the process of digesting lactose. Your answer would not be A because it is not raising nor decreasing acidity at all, it is not even talking about the acidity in foods. B is wrong because it does not talk about your liver whatsoever. And C does interfere with digestion, but it not harmful. It does talk about how bacteria can help those with lactose problems digest yogurt naturally. I hope I helped!! Have a great evening.
Answer:
True
Explanation:
Index fossil, any animal or plant preserved in the rock record of the Earth that is characteristic of a particular span of geologic time or environment. A useful index fossil must be distinctive or easily recognizable, abundant, and have a wide geographic distribution and a short range through time.
The given question is incomplete.The complete question is T/F When performing column chromatography to purify a protein of interest, one needs an assay to identify which fractions that contain the protein of interest. True or False: As discussed in lecture, we use a different assay for each different protein that we purify (For instance, the assay for protein A will be different than the assay for protein B which will be different than the assay for protein C, etc).
Answer: True
Explanation:
The sample contains different types of proteins in it and when the sample into chromatography column.
Different proteins have different affinity and based on the molecular size and weight they are separated.
So, according to the question if some one wants to assay protein A, it will be different for the protein B and different for the assay of protein C. This means that assays for different proteins will be different.
Hence, the given statement is True.
One word answer is Mutation nothing is perfect but some bacteria also have changes from conjugation aka sex between bacteria even though they are asexual organisms
Here is the answer that would best complete the given statement above. <span>The physical, chemical, and biological laws that operate today also in geologic past. This statement relates to the principle of </span>uniformitarianism. Hope this answers your question. Have a great day!
