Answer:
Explanation:
the answer is c
c. main sequence
b. red giant
d. supergiant
Our Sun is considered average because its temperature and absolute magnitude place it in the middle of the main sequence range of the H-R diagram. Correct answer: C
H-R diagram stands for the Hertzsprung-Russell diagram which was developed in the early 1900s by Ejnar Hertzsprung and Henry Norris Russell. The diagram plots the temperature of stars against their luminosity (the theoretical HR diagram), or the colour of stars (or spectral type) against their absolute magnitude (the observational HR diagram, also known as a colour-magnitude diagram).

Correct answer choice for question 1 is :
A) Type of wetland
Explanation:
Wetlands, as determined by the Convention on Wetlands of International Significance, cover lakes and rivers, bogs and swamps, wet meadows and peat lands, havens, bays, deltas and tidal flats, near-shore aquatic zones, mangroves and coral beaches, and human-made places such as fish pools, rice paddies, lakes, and salt pots. Wetland ecosystems endure a vital part of Europe’s biodiversity.

Correct answer choice for question 2 is :
A) Shallow
Explanation:
River reservoirs are normally small, and in the case of hill rivers, steep and erosion. In warm conditions, small rivers tend to be sheltered by an interlocking, above tree umbrella. Such situations result in cool, well-oxygenated streams that are sufficiently provided with a feed center of petals. Fine shreds of basic matter are delivered as the leaves are broken down by organic areas in the streams.

Correct answer choice for question 3 is :
D) All of the above
Explanation:
Sulfur dioxide and nitrogenous oxide released from industries and power plants infiltrate river ways by acidic rainfall. Sewerage and effluent are released into rivers in some regions. Pollution can decrease the pH of the water, attacking all organisms from algae to vertebrates. Biodiversity reduces with reducing pH.
