In _______, with the help of Rosalind Franklin, ____________ discovered the structure of DNA.
A. 1915, Watson and Crick
B. 1953, Watson and Chargaff
C. 1953, Watson and Crick
D. 1951, Chargaff
Answer:
The answer is C.) 1953, Watson and Crick. In 1953, with the help of Rosalind Franklin, Watson and Crick discovered the structure of DNA.
Explanation:
To be specific, James Watson and Francis Crick were the first people to make a 3-D model of DNA. Although it may not seem much today, as our technology has advanced so much ever since, it was big time in 1953. They discovered that DNA was shaped like a double-helix, or twisting ladder. Pretty intriguing if you ask me!
Our body needs both vitamin and mineral in a small quantity ,still they are important why?
Answer:
Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.
High blood pressure occurs when there is too much blood flowing through the blood vessels at one time. By changing the amount of water in the blood, blood pressure can change. The excretory system can help to lower blood pressure.
Which would most likely occur in the kidney?
More water would be transferred from the nephron.
Less water would be absorbed into the nephron.
The amount of water in the bladder would decrease.
The amount of water in the blood would increase.
Answer:
c
Explanation:
The kidney plays an essential role in regulating blood pressure by adjusting the volume and concentration of water and solutes in the blood. Therefore, to lower blood pressure, Less water would be absorbed into the nephron. Hence option B is correct.
What is a nephron?The nephron is the functional unit of the kidney that is responsible for filtering waste and excess water from the blood. When there is an excess of water in the blood, the kidney can decrease the amount of water that is reabsorbed into the body.
This would result in more water being excreted from the body in the urine, reducing the volume of blood and lowering blood pressure.
To achieve this, the kidney reduces the secretion of antidiuretic hormone (ADH) or vasopressin, which controls water reabsorption in the kidneys.
This decrease in ADH secretion causes the nephrons to reduce the amount of water they reabsorb from the urine, leading to an increase in urine output and a decrease in blood volume.
Therefore option B Less water would be absorbed into the nephron is correct.

A suspension of yeast cells is being grown under anaerobic conditions such that glucose is metabolized to ethanol and carbon dioxide. An inhibitor of alcohol dehydrogenase is added to the suspension, the cells rapidly die. Explain.
Answer:
The correct answer is - NAD needed to keep glycolysis going is not being recycled so the entire process is shut down and no ATP is produced
Explanation:
Alcohol dehydrogenase plays role in metabolizing the bulk of ethanol consumed as part of the diet and their activities contribute to the rate of ethanol elimination from the body.
Inhibitor of this zinc enzyme prevents it to perform its function which results in NADH generated during anaerobic conditions glycolysis cannot be recycled back to NAD+, So the ATP production pf anaerobic condition through glycolysis cannot be maintained.

The toxins responsible for botulism are proteins that inhibit the release of acetylcholine, which in turn can cause muscle paralysis. In extreme cases the paralysis can involve the respiratory muscles, and people can die of respiratory failure. This mechanisms of action indicates that the toxins are
Answer:
Poisonous substance.
Explanation:
This mechanisms of action indicates that the toxins are the poisonous substance which attacks on the respiratory system of the body that leads to the respiratory failure. Acetylcholine is the main neurotransmitter of the parasympathetic nervous system which is the part of the autonomic nervous system that contracts smooth muscles so inhibition of the release of Acetylcholine is the main cause of paralysis.
Uplift and formation of a mountain range divides a freshwater snail species into two isolated populations. Erosion eventually lowers the mountain range and brings the two populations together again, but when they mate, the resulting hybrids have sterile young. This is and example of which type of reproductive barrier
Answer:
Post reproductive isolation → Hybrid sterility
Explanation:
The biological concept of species states that individuals of a species can not mate and reproduce with individuals of another species. But if they get to reproduce, the progeny will not be viable or fertile. There will not be any reproductive success.
There are different reproductive isolation mechanisms, which are barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers are isolation mechanisms that prevent mating between two or more species. The prezygotic mechanism avoids fertilization between individuals of different species, while the postzygotic mechanism impedes the zygote to develop and reach the adult stage.
Postzygotic mechanisms or barriers include
Hybrid inviability, Hybrid sterility, Hybrid reduced viability or fertility, Cytoplasmic interactions.In the exposed example, sympatric speciation occurs. It seems that the mountains separating the snails´ populations made a place for speciation and the development of postzygotic barriers, specifically hybrid sterility. After the erosion process, both populations got to meet again. Snails from one population get to mate and produce offspring with the snails of the other population, but their progeny is sterile.

0 The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.
The dog and frog share a closer evolutionary ancestry than the gorilla and chimpanzee.
The dog is more closely related to the frog than it is to the chimpanzee.
All four organisms share a common vertebrate ancestor.
Answer:
(A) The skeletal structure of the gorilla and chimpanzee suggest a common evolutionary ancestry.
Explanation:
The vertebrate and many of the other parts of the skeletal structure of the gorilla and chimpanzee are alike. (and, by using a little background knowledge, you can figure this out by thinking; if humans share 98% of DNA with chimpanzees and about 96% of DNA with gorillas, then the two animals must share a lot of DNA as well.)
I hope this helps !!!
Answer:
1, 3, 4
Explanation:
The gorilla and the chimpanzee have very similar anatomy, so they are closely related.
There is a small resemblance between the dog and the frog, but nowhere close to the one shared with the gorilla and chimpanzee, so NO
the dog IS more closely related to the frog than the chimpanzee since it looks more similar
yes, all of them are vertebrates and therefore share a single vertebrate ancestor

Explanation:
The process of green plants make their own food by present sunlight is called photo synthesis
I don't need follow or thanks but please subscribe to my mom channel
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.

Where would you expect to find a mountain range caused by the collision of two continental plates on the map below? (100 points)
Public Domain
A
B
C
D
The correct answer is A.
Explanation
The image shows a map with the tectonic plates of the earth and four points are marked with the letters from A to D. The letter A indicates the collision of the Eurasian Plate and the Indian plate. The letter B indicates the border zone between Russia and the United States, however, there is no plate collision. The letter C marks are on the coast of Antarctica, but there is no collision between two plates. The letter D indicates an area on the equator, but it is not located on any plate collision. Therefore, the correct answer is A that shows the collision of the Eurasian Plate and the Indian plate where the great mountain chain of the Himalayas is formed where Mount Everest is located, the highest in the world with its summit at 8,849 meters above sea level. This is because many of the great mountain ranges of the world originate from the collision of plates such as the Andes and the Himalayas.
