While plants can produce their own energy using the process of photosynthesis, animals (and other organisms that can’t do photosynthesis) must eat to get energy from food molecules. Just like energy can be stored in the chemical bond between the second and third phosphate of an ATP molecule, energy can also be stored in the chemical bonds that make up food molecules. Most of the energy that we use comes from molecules of glucose, a simple sugar.
Answer:
True
Explanation: Conjugation is the temporary union of two bacteria or unicellular organisms for the exchange of genetic material.
In prokaryotes, new mutations accumulate quickly in populations, while in eukaryotes, new mutations accumulate much more slowly. The primary reasons for this are prokaryotes reproduce quickly and have vast populations.
<h2> Prokaryotes V/S Eukaryotes</h2><h3>Prokaryotes</h3>
Prokaryotes are organisms consisting of cells that don't have cell nuclei or any organelles that are enclosed in membranes. It follows that prokaryote's DNA is not contained within a nucleus.
The following components could be found in a normal prokaryotic cell:
- The membrane enclosing and guarding the cell is known as the cell wall.
- All of the cell's internal components, excluding the nucleus, are called cytoplasm.
- Some prokaryotic cells have filaments made of proteins called flagella and pili.
- A nucleoid is a cell structure that resembles a nucleus and contains genetic material.
- A plasmid is a little DNA molecule with independent reproduction.
<h3>Eukaryotes</h3>
Eukaryotes are organisms made up of cells with membrane-bound organelles and a nucleus that contains DNA in the form of chromosomes. Eukaryotic organisms can have several cells or just one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.

Answer:
A petroleum reservoir or oil and gas reservoir is a subsurface accumulation of hydrocarbons contained in porous or fractured rock formations. Such reservoirs form when kerogen (ancient plant matter) is created in surrounding rock by the presence of high heat and pressure in the Earth's crust.
Explanation:
Answer:Sugar molecules contain carbon, hydrogen, and oxygen: Their hydrocarbon backbones are used to make amino acids and other carbon-based molecules that can be assembled into larger molecules (such as proteins and DNA)
