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.
Answer:
: any of a series of chemical reactions in photosynthesis not requiring the presence of light and involving the reduction of carbon dioxide to form carbohydrate especially : calvin cycle.
Answer:
A niche is a way that a population uses the living and nonliving resources of its habitat.
Explanation:
A niche is the role a population has in it's habitat, and the second option is the best one that matches.
Answer:
<em>a. Cross-sectional study</em>
Explanation:
A cross-sectional analysis <em>includes at one particular point in time looking at data from a population.</em> Participants are chosen based on specific variables of interest in this type of study.
For developmental psychology, cross-sectional experiments are often used, but this approach is also used in many other fields, including social science and education.
Answer:
The correct answer is : Overconfidence.
Explanation:
A person who thinks his or her sense of direction or judgement is more accurate than it is actually is is known as overconfident, and this phenomenon is known as the overconfidence.
In this case, Jonah and Cathy attempted most of the question of the exam and secured less than 60% on the exam which suggests they have less knowledge than they thought they know, it is a sign of overconfidence.
Thus, the correct answer is overconfidence.
