Answer:
Although hydroelectricity is the least expensive energy source to generate electricity but still it is not used by most of the companies as it changes the normal flow of water,affects aquatic organisms,hamper fish habitats etc.
Explanation:
As hydroelectricity is fully depend upon water flow so it may create several consequences like drought,or another natural calamity may affect potentially.This may also affect the aquatic organisms that are fully depend on aquatic body.
Moreover, there are limited reservoirs for hydroelectric power plant .Only few are functional.
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
Answer:
Explanation:
Science is a tapestry and when you yank at one thread the whole thing may need to be rewoven but sometimes you have to yank the thread. I think the comparison means that scientists may misinterpret things but at the same time may discover new ways to view the universe.
Vesto Slipher contributions were that he took spectra of the spiral nebulae and discovered galactic redshifts. Slipher discovered that most of the objects were moving away from us at high speeds. As a result of this discovery Hubble correlated Slipher’s measurements with distance. He measured by other means to formulate his law which was that the farther away the galaxy was the Faster it was moving away From us.
Answer: The structures that are found in both eukaryotic and prokaryotic cell are-
ribosomes, DNA, cytoplasm.
Ribosomes are biomolecular complex, composed of RNA and protein and act as the site for protein synthesis in all the cells of the living organisms.
DNA (deoxyribonucleic acid) is considered as the genetic material of all life forms. It possesses the genetic instruction in the form of nucleotide sequences.
Cytoplasm is the fluid compartment of all the cells (where all the essential biochemical reactions take place) that is surrounded by cell membrane.
Thus, ribosomes, DNA, cytoplasm is the right answer.
