Some people see wind energy as a clean alternative to fossil fuels. Others believe that utilizing this renewable energy resource
Y_Kistochka [10]

Answer:

Renewable energy resource as an obstacles for the growth of migratory salmon populations: It is now believed that the reduce access to spawning grounds and nursery areas, leading to a decrease in migratory fish populations is due to the dam structures of large storage-type schemes, which can create great obstacles for the movement of migratory fish species.

Explanation:

  • Storage-type schemes ( big dams) can significantly change the downstream flow regime,and may also alter water temperature and quality, and even make it inhabitable for fish to live.
  • As the storage of water can be linked with high evaporative losses, which in turn results in high life cycle water footprints compared to other sources of electricity.

<u>Run-of-river (ROR) schemes are HEP schemes: </u>

They operate without water storage, using the flow within a river channel.They are ecologically friendly and do not disturb the natural mechanism for the migrating salmons.

Working Principle:

They are normally used to regulate water levels, which allows a proportion or part of flow to be diverted down a secondary channel to a turbine before it is returned to the main channel further downstream.

There are some modern turbine types used in ROR HEP(hydroelectric power) schemes, which are also designed to allow fish to pass through the system unharmed if the fish do pass through the intake screens.

Restriction enzymes: A) act at the membrane to restrict the passage of certain molecules into the cell. B) are highly specialize
Elenna [48]

Answer:

C) are sequence-specific DNA endonucleases

Explanation:

Restriction enzymes represent a type enzyme capable of recognizing short nucleotide sequences to cut at specific restriction sites in the DNA, these sites are known as target DNA sequences. Some of the most commonly used restriction enzymes are <em>EcoRI</em>, <em>BamHI</em> and <em>HindIII</em>, isolated from <em>Escherichia coli</em>, <em>Bacillus amyloliquefaciens</em> and <em>Haemophilus influenza</em>, respectively. Restriction enzymes are endonucleases because these enzymes only cleave the phosphodiester bond within the DNA chain, conversely to exonucleases, which cleave nucleotides from the end of the polynucleotide DNA strand.

What structure provides a protective environment in which the fetus's temperature is well regulated and protects the fetus from
Gnom [1K]

Answer;

The amnion

Explanation;

-The amnion is a tough, thin membrane that surrounds a developing fetus in mammals, reptiles, and birds. It is the first of the three cavities (amnion, chorion and yolk sac) in the embryo and is formed on 8 dpc.

-In the human body, the amnion is the first of three cavities, including the chorion and yolk sac, that work together to keep the developing fetus nourished and protected.

-The amnion provides a protective environment in which the fetus' temperature is regulated and protects the fetus from friction caused by the mother's movements.
