Answer:
The basic function of the light reactions of photosynthesis is the conversion of solar energy to chemical energy.
Explanation:
In photosynthesis, the light energy is captured by chlorophyll pigment which is present in the thylakoid membrane. Then this light energy is used split water which releases the electron that enters the electron transport chain. Then electrons move through several electron carriers and helps to generates NADPH and ATP.
These NADPH and ATP are used in the Calvin cycle to fix the carbon into carbohydrates like glucose. Glucose molecules is then used by the plant to get energy source and to make structural components like cell wall. Therefore during photosynthesis solar energy is converted into chemical energy like glucose.
Answer:
In eukaryotes, thousands of chemical reactions are able to take place in separate compartments called organelles.
Explanation:
Organelles are specific cellular structures that are the means of compartmentalizing the various functions that occur within cells.
Examples of organelles and their functions are:
- <u>Nucleus</u>: contains DNA and in it occur the replication of this molecule and its transcription into RNA.
- <u>Rough endoplasmic reticulum</u>: protein synthesis and conjugation of these molecules occurs.
- <u>Mitochondrion</u>: houses all oxidative phosphorylation reactions and the electron transport chain for ATP synthesis to occur.
The organelles are then the structures that allow the development of the multiple functions that a cell has.
The other options are not correct because:
- <em><u>Bacteria</u></em><em> is a prokaryotic organism.
</em>
- <em><u>Prokaryote</u></em><em> refers to simple organisms that lack organelles.
</em>
- <em><u>Proteins</u></em><em> are biomolecules that allow the structure and function of living beings.</em>
Energy is the power we use for transportation, for heat and light in our homes and for the manufacture of all kinds of products. There are two sources of energy: renewable and nonrenewable energy.
<span>
Nonrenewable Sources of Energy</span>Most of the energy we use comes from fossil fuels, such as coal, natural gas and petroleum. Uranium is another nonrenewable source, but it is not a fossil fuel. Uranium is converted to a fuel and used in nuclear power plants. Once these natural resources are used up, they are gone forever.
Renewable Sources of Energy
Renewable sources of energy can be used over and over again. Renewable resources include solar energy, wind, geothermal energy, biomass and hydropower. They generate much less pollution, both in gathering and production, than nonrenewable sources.
Hope this helps xox :)

Explanation:
The average kinetic energy of a gas particle is directly proportional to the temperature. An increase in temperature increases the speed in which the gas molecules move. All gases at a given temperature have the same average kinetic energy.
Scientists worked backwards by looking into the amino acid sequence to determine the DNA base. They started with the mRNA which transcribes the codon into respective amino acids. This human gene is found on top of chromosome 11 in human DNA.
