Answer: 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.
Explanation:
Asbestos fiber accumulate in the <em>lysosomes.
</em>
Option: (b)
<u>Explanation:
</u>
Asbestos is a natural group of minerals and it is composed of thin and needle-like fibers. An asbestos causes several diseases like cancers and so on, including asbestosis and mesothelioma.
Although asbestos extend and fireproofs materials, this materials are banned in ‘many countries’. But asbestos are not banned in the United States.
Lysosomes are important part of the ‘endomembrane system’ because lysosomes are formed from the ‘endoplasmic reticulum’ and these products are synthesized and processed by the ‘Golgi’.
Estuaries are among the world's most productive ecosystems. Estuaries are essential to the success of numerous fish and shellfish species of great commercial, ecological, and recreational importance. Estuaries are also the focal points for pollutants entering the sea from the land, and are now the most nutrient-enriched ecosystems on earth.
When an atom gains an electron it acquires a negative charge and becomes a cation. As chlorine gains an electron to complete its octet it will become cationic in nature
Answer:
The three main domains into which the organisms are classified are archaea, bacteria and eukarya.
Archaea : The archaea is more closely related to eukaryotes. Although they have bacteria like metabolism and have 70'S chromosomes but shows presence of introns and shows similar molecular mechanism like replication, transcription and translation similar to eukaryotes. These are found in the extreme conditions as well.
Bacteria: The bacteria have circular DNA with 70'S ribosomes. The cell membrane has ester linkage and no nucleosome formation occur in bacteria. The transcription and translation are coupled together with no further modification.
Eukarya: The eukaryotes have linear DNA with 80'S ribosomes. The cell membrane has ether linkage and proper nucleosome fprmation occurs in eukarya. The transcription and translation occurs separately in the distinct compartments and further modification occurs.
