Which scientist created tests that helped confirm that bacteria and other microorganisms cause a variety of diseases

Answers

Robert Koch is the scientist who created tests that helped confirm that bacteria and other microorganisms cause a variety of diseases. He is a German physician and a microbiologist who is known in identifying specific causative agents in a number of illnesses which includes cholera, tuberculosis and anthrax. Due to this contribution to medicine, he received a Nobel Prize in 1905.

Hi there!

Answer: Robert Koch

Explanation: In 1890, Robert Koch created a series of test to assess the germ theory of disease. In 1676, bacteria was first observed by Anton Van Leeuwenhoek. In 1859, Louis Pasteur disproved spontaneous generation and developed the germ theory of disease. In 1910, Paul Ehrlich created the first synthetic antibiotic.

A biologist analyzes the DNA sequences of one gene in three different primates . The biologist finds that primates A and B have almost exactly the same DNA sequences for that gene. The DNA sequences in primate C are significantly different from those of A and B. This information allows the biologist to infer that:________

Answers

The question is incomplete as it does not have the option which are:

  • primates A and B are more closely related to each other than either is to primate C.
  • all three primates appeared on Earth at about the same time.
  • either primate A or primate B must be a direct ancestor of primate C.
  • primate C must have been the ancestor of both primate A and primate B.

Answer:

Primates A and B are more closely related to each other than either is to primate C.

Explanation:

In the given question, on the basis of the given information, it can be predicted that the Primate A and B are more closely related to C as the DNA sequences of these two primates are almost similar. The similarity of the sequence suggests that these primates have descended or diverged from a common ancestor.

The DNA sequence of C is different from both A and B which shows that both A and B are different from the C.

Thus, the selected option is the correct answer.

Answer:

The DNA sequencing is important for the determination of the evolutionary relationship with the organisms. The ancestory and descendants can also be identified by DNA sequencing.

Three primates A,B and C DNA sequences has been identified. It is given that primates A and B has same sequence and they are more closely related with each other. The primates C is unique and do not share relation with the primates A and B.  

What is an alternative to living in an urban area?
