Answer:
Burning of woods has a negative impact on the climate.
Explanation:
Burning of woods for heating has a negative impact on our climate because it releases carbondioxide gas which is a greenhouse gas that trapped the reflected solar radiation and leads to global warming. We have to used alternative methods for heating such as electric heater instead of burning of wood which produce no pollution and can fulfill the requirement of heating so from the above discussion we can say that the activity has a negative impact on the environment.
Answer: In the lab activity, I used a virtual watershed to demonstrate how pollutants enter and flow through the watershed. I constructed food chains to show how biotic factors are related. I also predicted and modeled how human activity affected the biotic factors in an ecosystem. Based on my observations, I can conclude that biotic and abiotic factors are closely linked and that human activity that changes the environment, like pollution, can affect all the other parts of an ecosystem in a negative way.

option c
Explanation:
A natural blind spot also called the optic disc in the eyes occurs where the blood vessels and axons of the ganglion cells leave to form the optic nerve. it is so called because there are no receptors (rods and cones) in this part of the retina. Artificial blind spots can also be formed when something prevents light from getting to the photoreceptors which are the rods and the cones.
The source that is considered reliable is an article from a scientific journal.
An article that is considered a reliable source is that article that has undergone a thorough review by academic scholars.
A typical example of such articles are found in scientific journals.
Articles from a scientific journal are known to be from a reliable source because:
- the author must have cited studies or other sources to be considered valid and reliable
- the author must have done some research to provide evidence and name the sources they use.
- the authors work is usually peer reviewed from time to time.
- the articles in scientific journals cannot be altered by anyone except the original authors.
Therefore, the source that is considered reliable is an article from a scientific journal.
