Where is chemical energy contained in a compound

Answer: Bonds.

Explanation:

The energy of the compounds lies in the bonds present in the compound. Energy is released from the compounds when the bonds are broken.

Example: Adenosine triphosphte is hydrolyzed and adenosine diphosphate and inorganic phosphate is produced. This process releases energy by the breakdown of bonds which is used for carrying various metabolic processes of the body.

Hence, the chemical energy is stored in the bods of the compounds.

In at least three sentences, describe why transitioning to a hydrogen economy has advantages. In at least three sentences, explain three disadvantages associated with hydrogen fuel use. Why is a high use of renewable energy necessary to make hydrogen fuel an environmentally sound alternative? Respond in one complete paragraph.

Hydrogen supply s abundant and its a cleaner i.e. renewable form of energy.
This is also non-toxic. The efficiency of this energy is also higher.
Disadvantages are that it is an expensive source of energy. Because of the low density of Hydrogen gas, its storage is difficult. The transportation of Hydrogen gas is also difficult due to its low density.

If a trait is not well adapted to current local conditions, what might be the reasons why it is not, and how might one check to see which of those reason(s) is correct?

Non-availability of a proper niche to inhabit an environment can be a reason of non-adapting of local conditions in a trait. This may also be due to the filtering out of the trait by the environment. Further, other traits which are supporting the growth of the organism in this particular environment may be acting as crucial and significant to the survival, as compared to this trait

Sophia is observing slides under a microscope while adjusting its mirror so that a circle of light can be seen. Which type of microscope is she using? electron microscope compound light microscope scanning electron microscope

Answer:

The correct answer is the compound light microscope.

Explanation:

A compound light microscope comes with two or more lens and it has its own light source. There are objective lenses in a nose piece close to the specimen and ocular lenses in the binocular eyepieces.

A compound light microscope is comparatively small, so it’s easy to use and store, and it has its own light source.

Compound light microscopes reveal very fine details in slides because of their multiple lenses.

Thus, the correct answer is the compound light microscope.

A father has one allele for detached earlobes and one allele for attached earlobes. What is the probability that he produces a gamete with the allele for attached earlobes in percentage?

With the presence of a heterozygous allele for earlobes, the gametes produced by the father will have 50 percent chances of bearing an allele for attached earlobes. This means that half of the gametes will have an allele for attached earlobes, and half of them will have an allele for detached earlobes.

Earths oceans absorb carbon dioxide emitted by humans and other animals, and eventually turn it into carbonate rocks. Which ''spheres'' are part of this process? Select all that apply. Biosphere Exosphere Geosphere Cryosphere Atmosphere Hydrosphere

Answer:

Option (1), (3), (5) and (6)

Explanation:

Carbon dioxide is a gas that is released by the living organism during respiration. This gas is then released into the atmosphere. This CO₂ gas is then carried to the lithosphere from the atmosphere with the help of rainfall. Now, these atmospheric CO₂ gas reacts with the water forming carbonic acid. Carbonic acid is a weak type of acid. This carbon is then squeezed and constricted to the sediments and muds, forming rocks such as shale and limestone.

Here, the carbon is present in the form of carbonate rocks.

Thus, this entire process takes place interacting with the biosphere, atmosphere, hydrosphere and geosphere.

Hence, the correct answer is option (1). (3), (5) and (6).
