Answer:
1. Maurice Wilkins
2. Rosalind Franklin
3. Linus Pauling
4. Erwin Chargaff
5. James Watson
6. Francis Crick
7. Rosalind Franklin
8.
Explanation:
1. Maurice Hugh Frederick Wilkins was a British scientist, both a molecular biologist and physicist. He made an outstanding contribution to the scientific discovery of the DNA structure. He is well known for his work in the 1940s at King's College in London, where he used optical spectroscopy to understudy the structure of the DNA.
2. Rosalind Elsie Franklin was an expert x-ray crystallographer and chemist, she contributed immensely to the understanding and discovery of the DNA structures as well as the molecular structure of coal, RNA and viruses.
3. Linus Carl Pauling was an American scientist who made a huge impact in the field of molecular biology, he played an important role in the molecular modelling of proteins and this helped in further understanding the DNA code.
4. Erwin Chargaff was an American scientist who formulated the Chargaff's rules and his experimentations helped to show that the ratio of adenine in a DNA molecule was equivalent to the ratio of thymine, as well of the ratio of guanine in a DNA molecule was equivalent to the ratio of cytosine.
5. James Watson and Francis Crick both worked in the Cavendish Laboratory to elucidate the 3- dimensional structure of the DNA.
6. Maurice Hugh Frederick Wilkins along with James Watson and Francis Crick won the Nobel Prize for Physiology in 1962 for their discovery of the molecular structure of the DNA.
7. Rosalind Elsie Franklin was an English scientist and x-crystallographer was famous for "photo 51", this helped to first prove that the DNA was a double helix structure.
8. Rosalind Elsie Franklin worked out mathematically what a helical defraction should look like in an x-ray defraction photo.
Answer:
b. anthrax
Explanation:
Staphylococcus aureus is a bacterial species that exists in nature as a pathogen (disease-causing). Since Staphylococcus aureus is a pathogen, it can be attributed to cause certain diseases. Based on the options provided, the diseases caused by this bacterium include:
- Scalded skin: This is also called Staphylococcal scalded skin syndrome (SSSS). It is caused by a toxin produced by Staphylococcus aureus.
- Meningitis: Staphylococcal meningitis, as the name implies, is caused by Staphylococcus aureus.
- Syndrome impetigo; This is a common skin infection in children, which is caused by Streptococcus spp and Staphylococcus aureus bacteria.
From the options provided, Anthrax is caused by another different bacterium called Bacillus anthracis.
Very simple. At rest, you have a number of bpm. After exercise, the heart can't return abruptly to the rest speed, and it keeps a faster rate for a while.
Answer:
Two main functions of keeping the stomach highly acidic are:
C) Denature proteins to ease their breakdown
D) Kill bacteria to prevent food borne disease
As, the stomach maintained a high acidic to kill the all bacteria and denture the protein for ease in the digestion system. The diaphragm keeping acid in out stomach. It basically help stomach in the activation of enzymes pepsin which helped in the breakdown of the proteins. And the acidic stomach prevents from the certain microbes produced in our stomach.
Depends on if you mean physical weathering or chemical weathering.
