Why?
b. are not frogs, because frogs never have red eyes.
c. live in banana trees.
d. none of the above
Answer:
The nucleic acids (DNA and RNA)
Explanation:
DNA as the genetic material which located in nucleus
RNA the number cellular activities
Answer:
first- class proteins comes from eggs , meat , fish and dairy products while non - animals related foods ,like vegetables and fruits, provide second - class proteins . first - class proteins contain a necessary amount of these important amino acids , but second - class proteins only contains some of them.
Explanation:
Renewable resources can be naturally replenished, while nonrenewable resources are finite and deplete over time. Human activities significantly influence the environment, often leading to environmental degradation, but the shift towards renewable resources can mitigate these impacts and promote sustainability.
Renewable and nonrenewable resources are two distinct categories of natural resources, each with significant implications for the environment.
Renewable Resources:
Definition: Renewable resources are those that can be naturally replenished or regenerated within a relatively short time frame. They are sustainable over the long term and have the ability to renew themselves.
Examples:
a. Solar Energy: Solar panels harness energy from the sun, a virtually limitless source of power.
b. Wind Energy: Wind turbines convert wind motion into electricity.
c. Forests: Trees can be replanted and regrown, providing timber and other forest products.
Nonrenewable Resources:
Definition: Nonrenewable resources are finite and deplete over time. They cannot be readily replaced within human timeframes.
Examples:
a. Fossil Fuels: Coal, oil, and natural gas are finite energy sources formed over millions of years.
b. Minerals: Metals like gold and non-metals like diamonds are extracted from the Earth's crust.
c. Nuclear Fuel: Uranium is a finite resource used for nuclear power generation.
Human Activities and Environmental Impact:
Human activities have profound effects on the environment. For example, the burning of fossil fuels for energy production contributes to air pollution and climate change. Deforestation disrupts ecosystems and reduces biodiversity. Mining operations can lead to habitat destruction and water pollution. Conversely, renewable energy sources like wind and solar power produce fewer greenhouse gas emissions and have a lower impact on the environment.
