D. seems the most probable since plastic is barely biodegradable.
The answers are solar for the first one, and chemical for the second one
The <u>Coast Guard</u> works with the Environmental Protection Agency to enforce marine biology regulations along the coast and in the Great Lakes channels.
Answer: Option A
<u>Explanation:</u>
The Environmental Protection Agency (EPA) takes initiative to instill certain regulations to maintain the Ocean and its resources with the help of coastal guards and NGO’s. The Ocean coast is polluted due to various avoidable and unavoidable pollutants like oil leakage, industries letting in their waste, ship wrecks etc.
President Richard Nixon was the one who created this EPA. The EPA takes utmost care by educating the people of the necessity to maintain the coast in a disciplined attitude so as to have a pollution free oceanic coast which would in turn not adhere into the relevant working stream. Avoiding litter is the main rule that has been imposed.
Answer:
convergent evolution
Explanation:
If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.
Answer:
The answer is D. Food security
Explanation:
Sustainable Agriculture:
Sustainable agriculture or farming is a combination of agricultural policies, practices and measures that yield the maximum profits and benefits without negatively impacting the environment.
Sustainable agriculture, as an idea, basically means to utilizes resources responsibly so that the future generations can reap the benefits as well.
Sustainable Farming Approaches:
Approaches to sustainable farming include policy as well as farming technique interventions. Some of these methods are:
- Crop rotations that involve planting diverse crops on a piece of land, as opposed to monoculture and intensive farming that gradually makes the soil nutrient deficient.
- Cover cropping after a season of monoculture to prevent leaving the soil bare til the next season.
- Use of renewable energy resources and integrated pet management to generate energy efficiently and minimize crop losses respectively.
Food Security:
Food security entails that healthy, nutritious and safe food is readily i.e. physically and economically available for all people. Food security is one of the major sustainability goals.
