Which element is not one of the most abundant elements in living organisms?a. hydrogen
b. zinc
c. oxygen
d. carbon e.nitrogen

Answers

Answer: The correct answer is Option b.

Explanation:

Abundant elements are defined as the elements which are present in huge amount on earth. The elements which are required by the living organisms in huge amounts are known as essential elements.

There are in total six essential elements which are required by the body in large amounts. They are Carbon (C), Hydrogen (H), Oxygen (O), Nitrogen (N), Phosphorus (P) and Sulfur (S).

From the given options, zinc is the only metal which is not required by the living organisms in huge amounts.

Thus, the correct answer is Option b.

zinc. all the other elements are found in living organisms to a relatively large extent.

1. What is the difference between renewable and nonrenewable resources? Give at least three examples of each. How do human activities influence and modify the environment? In your own Word's please

Answers

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.

A non-renewable resource (also called a finite resource) is a resource that does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. An example is carbon-based, organically-derived fuel. The original organic material, with the aid of heat and pressure, becomes a fuel such as oil or gas. A renewable resource is a resource which can be used repeatedly because it is replaced naturally. Examples are: oxygen, fresh water, solar energy, timber, andbiomass. Renewable resources may also include goods commodities such as wood, paper and leather.

how can an increase in the use of burning of fossil fuels can lead to an increase in average global temperature?

Answers

Answer:

burning of fossil fuels produces myriad types of greenhouse gases. usually, green house gas is important to keep the earth's temperature normal without being too cold. unfortunately, increase of fossil fuels burning in recent years have lead to excessive amount of the greenhouse gas in the atmosphere, which causes too much heat from the sun to be trapped in the earth atmosphere.

If a cell is placed inside a solution that has a higher concentration of solute than on the inside of the cell what can be said about the movement of water?a. water will move in and out of the cell at the same rate.
b. water will move out of the cell causing it to shrivel.
