Mutation and natural selection trigger the evolution of a species

Mutation means there is new variations, as the mutations are passed on to offspring this results in evolution.

Natural selection means a change in phenotypes (the visible traits of a species) of future generations to increase the fitness of a species. This is evolution in progress.

Human opinions do not influence evolution and an unchanged environment would not result in evolution.

I hope this helps! I'm happy to answer any other questions you might have :)

ILL GIVE 60 POINTS AND A BRAINIEST
tigry1 [53]

Answer:

1. The school board wants to clear the forest surrounding the local high school to build more fields for high school sports. Following environmental factors need to be investigated before clearing the land:

1. Destruction of natural ecosystem: As forest will be cut the land will be barren. There will be loss , extinction and migration of faunal species. So, the normal balance of ecosystem will b disturbed.

2. Chances of climatic fluctuations: As, forest will be cleared, the water, carbon and oxygen cycle in the atmosphere will be disturbed. The region may not acquire adequate rainfall, temperature of the area will change drastically.

3. Soil erosion: As, forest will be cleared the soil will not be hold up and the loose soil gets wiped out from the location by water or air.The cutting of trees can cause flooding from nearby water body.

2. Two ways to reduce air pollution and slow climatic change are:

1. Control use of fossil fuels: Fossil fuels like coal, petrol, kerosene are used in automobiles, industries and house hold activities. These fossil fuels are organic in nature and adds up carbon dioxide, carbon monoxide, nitrogen dioxide gases in air and raises the atmospheric temperature and are responsible for air pollution. Therefore, the use of fossil fuel should be in control manner.

2. Planting more number of trees: The trees are responsible for fixing atmospheric carbon from air for photosynthesis. So, they can decrease the amount of atmospheric carbon abundantly present in forms of carbon dioxide and carbon monoxide, which are chief air pollutants. These carbon products are responsible for raising temperature so planting of trees can prevent raise of temperature.

Answer:

D. In an ocean heated by volcanic activity

Explanation:

Most of Earth was covered in water, early organisms weren't evolved enough to walk on land at the time. There are some organisms that feed off of volcanic activity and use it as an energy resource and would adapt to the heat.

<em>"Hot spots create volcanoes on the seafloor. If these volcanoes rise above sea level to become islands, and if they occur in tropical waters, coral reefs will form on them. Since the volcanoes are cones, the reef forms in a circle around the volcano."</em>

<em>-</em><u>https://courses.lumenlearning.com/earthscience/chapter/ocean-organisms/</u>

<em>"Discovered only in 1977, hydrothermal vents are home to dozens of previously unknown species. Huge red-tipped tube worms, ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme deep ocean ecosystems found near undersea volcanic chains."</em>
