What is the major cause of the greenhouse effect? view available hint(s) what is the major cause of the greenhouse effect? exces
Strike441 [17]
The major causes of the greenhouse effect is excessive carbon dioxide gas in the atmosphere. The greenhouse effect is a process that warms the Earth's surface. When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by green house gases, such as carbon dioxide, water vapor, metahne, nitrous oxide, and ozone. The absorbed energy warms the atmosphere and the surface of the Earth.

During aerobic respiration, electrons travel downhill in which sequence?
iris [78.8K]

Answer:

The correct answer will be option-B.

Explanation:

Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.

The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.

The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.

These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.

Thus, Option-B is the correct answer.

Dr. Paul Ehrlich observed that the differential stain developed by Dr. Gram suggested bacteria could be killed differentially by
Alex787 [66]

Answer:

The correct answer is Glycocalyx, ribosome and cell wall.

Explanation:

Glycocalyx is mainly found in bacteria that makes a protective covering outside the cell wall in the form of capsule of bacteria and provide protection to bacteria from host immune cell.  

Bacterial ribosomes are different from human ribosomes. Bacteria contain 70s ribosome while humans contain 80s ribosome so ribosomes are potential targets for many drugs present today.

Bacterial cell contain cell wall which is made up of peptidoglycan or lipopolysaccharide but human cell does not contain a cell wall, therefore, many drugs are designed to destroy cell wall of bacteria like penicillin.

So glycocalyx, ribosomes, and cell wall can be potential targets for Dr. Ehrlich's "magic bullets" due to significant difference or absence from humans.
