Answer:
The correct answer is A) An image indicating the shape of a DNA molecule. See the explanation below, please
Explanation:
Rosalind Franklin through studies of X-ray diffraction and crystallography, showed the double helix structure of the DNA molecule.
The answer is A. When a potent drug is discovered, it has to undergo animal and human trials to test it ADMET (Absorption, Distribution Metabolism, Excretion, and Toxicity) properties. Using tissue cultures to test drugs, such as cancer drugs, prevents the incidence of subjecting humans to the unknown adverse effects of the drugs before the drugs are determined to be safe for use.
Answer:
In agriculture specialization, farmers produce one crop instead of so many crops. In other words, the farmers, adopt specialized farming. By doing so they avail all those benefits which are accrued to the big businesses. Hence the goods are produced on a large scale.
Answer:
The function of the bones in bats that are homologous to finger bones in humans is to FLY.
Explanation:
Homologous anatomy- it means that the organisms have the same anatomy or bone structure but it is used for different functions. They are evolved from a common ancestor.
human beings, bats and birds have the homologous forearms. They have the same types of bones present in their forearm but however each of them use it for different purposes. A human being uses to lift things, cook, type and other mundane things whereas a bat uses it's forearms as wings to fly.
The correct answer is Oxygen.
The surface of the Earth was liquefied. As the Earth cooled, an atmosphere generated primarily from gases erupted from volcanoes. It constituted methane, hydrogen sulfide, and ten to 200 times as much as carbon dioxide in comparison to today's atmosphere.
It was considered that there was an extreme volcanic activity for the initial billion years of the existence of the Earth. The initial atmosphere was possibly majority carbon dioxide will no or little concentration of oxygen. There were slight quantities of ammonia, water vapor, and methane.
