How can nearly all energy on earth be tracked back to nuclear fusion?

Answers

Answer 1

Answer: see if this helps Nuclear fusion seems a great solution for the demand of Energy. It is safe, has infinite fuel, produce a negligible amount of waste etc.There are enormous technical challenges still to overcome, but let’s assume one moment, for the sake of the argument, that we find a way to solve them and the power plant is now “technically ready”.Reading around seems that the cost of such plant will be huge: a lot of material required, complexity in the construction etc. Such construction costs include a very relevant energy price. For instance digging all the material and “transform” them requires a lot of energy. I have the feeling that the energy produced all over the life cycle has the same order of magnitude: i.e. at the end the “net balance” is not so convenient. Considered the huge capital cost the ration “Net energy produce / cost” would be quite poor as well.

What property of water describes the molecule as acting like a tiny magnet?

Answers

Answer:

Intermolecular forces

Water is a dipole and acts like a magnet, with the oxygen end having a negative charge and the hydrogen end has a positive charge. These charged ends can attract other water molecules.

The entire electron densities of the two hydrogen atoms get attracted towards the oxygen atom. Thus a polarity develops in each O−H bond, and therefore, the water molecules are polar in nature and act like little magnets.

What happens to a species when the environment undergoes a radical change (e.g. due to climate, food source) and the organisms do not adapt? Explain your answer in not less than 3 sentences. May cite a hypothetical; situation to explain the answer.

Answers

Answer:

If an environment rapidly changes and an organism cannot adapt it will mostly die out. For example, some birds have long, thin beaks that let them reach insects inside trees. If these insects were to disappear for some reason and seeds became the main food source then the birds with long, thin beaks would not be able to eat. Other birds with different adaptations, like short, strong beaks, would be properly adapted to this new environment. So, this second species would replace the first species.

Answers

If the results from the controlled experiment to test the effects of tea tree oil on the growth of Trichophyton rubrum are valid, a similar experiment should produce results that are similar but slightly different data.

What is reproducibility?

In science, valid results from experiments must be reproducible.

In other words, the same experiment carried out by different researchers must produce similar results with very little to no variation.

If results from an experiment are not reproducible, such results cannot be valid as far as science is concerned.

Short Tandem Repeat profiling is a technique in molecular biology used to compare allele repeats known as STRs at specific loci in DNA between two or more samples.

The PCR (polymerase chain reaction) technique used in STR profiling involves making multiple copies is a particular segment of DNA in order to make enough quantities detectable in the analysis.

Therefore, PCR technique is important in STR profiling to detect the number of Stars at a specific gene loci.

Answers

We can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

Why did the water vaporize and then condense?

As the water was heated by the electric heater, its internal temperature increased. Once this temperature reached the boiling point of water, the water vaporized or evaporated into a gas. This gas then reached the mirror, where it collected and cooled down, condensing back into a liquid in the form of water droplets.

Therefore, we can confirm that throughout this experiment, the water vaporized, then condensed into a liquid once again.

For the following organisms, choose the correct order of increasing trophic level. a. fungi, deer, wolf and grass b. fungi, grass, wolf and deer c. grass, deer, wolf and fungi d. grass, fungi, wolf and deer Please select the best answer from the choices provided

Answers

Answer:

Your answer is C

Explanation:

The correct answer is for the following organisms, is grass, deer, wolf and fungi that is the option c as the  trophic level refers to the position of an organism in a food chain.

The trophic level refers to the position of an organism in a food chain or food web. In a food chain, energy flows from one trophic level to the next as organisms are eaten by other organisms. Grass occupies the first trophic level as a primary producer. Deer occupy the second trophic level as they feed on primary producers (grass). Wolves are carnivores and occupy the third trophic level as they feed on herbivores (deer). Fungi occupy the last trophic level as decomposers, so this is the correct order among all other options.

Thus, correct option is option c.

What is an Non-native or Invasive species do to the environment?

Answers

Answer:

They can destroy the ecosystem or out - compete a native species.

Explanation:

For example, if an invasive species of tree is taller than the native species of tree and therefore takes up more sunlight, leaving the shorter native tree not enough sun, then it will effectively kill the native tree.

Also non - native and invasive are not the same thing. A non - native species doesn't necessarily mean it's invasive. It is only invasive if it begins to have a significant impact on the ecosystem it is inhabiting.
