The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
The correct options are, frying an egg and burning candle.
Explanation :
Physical change : It is a change in which no new compounds are formed only changes occurs in size or state of substance. In this, there is no changes in the substance or compound.
Chemical change : It is a change in which a new compounds are formed by the chemical reaction. Changes occurs in their chemical composition and properties.
Frying an egg : It is a chemical change because a new substance is form by heating.
Burning a candle : It is chemical change because new substances are formed (carbon dioxide, water and heat) by burning.
Boiling alcohol : It is physical change because only changes in the state.
Melting and ice : It is a physical change because only changes in the state.
Making coffee : It is a physical change because no new substance is formed.
Therefore, frying an egg and burning candle are the example of chemical change.
Answer:
No. Since Model A shows an equinox, it shows that it is spring in one hemisphere and fall in the other hemisphere.
Explanation: exact answer on plato
Answer:
The correct answer is C. In the plaque assay for bacteriophages, the plaque is a clear zone caused by a zone of lysis.
Explanation:
The plaque assay is an approach used for titering bacteriophage stocks or determining the quantity of infectious virus in a sample. Plaques are visualized if you spot the phage on a lawn of growing compatible bacteria. Each plaque indicates an initial infection with one phage followed by lysis of neighboring bacteria in the lawn. Only viruses that cause visible damage of cells can be assayed in this way. The plaque assay is used to determine viral titer as plaque-forming units per ml so that known amounts of virus can be used to infect cells during subsequent work.
