What else can I help you with?
What creates the energy to generate ATP?
Biological oxidation of Glucose, Fatty acids and Glycerol, as well as extra Amine acids, creates the energy for generation of ATP.
Describe the Four stages of the hypothesis for the origin of life on earth?
Abiotic synthesis of organic molecules: Simple organic molecules were formed from inorganic compounds under early Earth conditions. Polymerization: These organic molecules polymerized to form larger molecules like proteins and nucleic acids. Formation of protocells: These molecules self-assembled into protocells, which were the precursors to modern cells. Development of self-replicating molecules: Self-replicating molecules emerged within protocells, leading to the evolution of life on Earth.
Why does a pineapple conduct electricity?
Biological materials, such as this one, will usually conduct electricity due to ions in the liquid. Since an ion has an electrical charge, and is relatively free to move around, it can conduct an electrical current.
What are the relative charges on eiter side of the membrane?
The inside of the cell is negatively charged compared to the outside due to an abundance of negative ions such as proteins and nucleic acids inside the cell. This creates an electrical potential across the membrane known as the membrane potential.
What kind of substances can electric current can flow through?
Electric current can flow through conductive materials such as metals (copper, silver, aluminum), electrolytes (saltwater, acids), and certain semiconductors (silicon, germanium). Insulating materials, like rubber and plastic, do not allow electric current to flow.
Why do solution containing acids conduct an electric current?
To conduct an electrical current, you need movable charges. In such solutions, those are available in the form of ions.
Which step has not been accomplished by scientists studying the origin of life?
formation of protocells that use RNA to reproduce themselves
Is an acid or base better at conducting an electrical current?
Bases are better at conducting an electrical current because they contain ions that can move freely and carry a charge. Acids, on the other hand, may contain fewer ions and therefore have lower electrical conductivity.
How does acid strength affect electrical conductivity?
The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.
What creates the energy to generate ATP?
Biological oxidation of Glucose, Fatty acids and Glycerol, as well as extra Amine acids, creates the energy for generation of ATP.
Why was the evolution of nucleic acids important to the evolution of protocells?
Nucleic acids have a number of important features. They are self replicating, and they also have the capacity to synthesize proteins. These proteins, in turn, can regulate or cause all other biochemical processes involved in life. So nucleic acids become the means to store information about how any organism functions, and to bring about those functions as needed.
Which Substance When Dissolved in Water will Conduct an Electrical Current?
Ionic compounds such as salt (sodium chloride) or acids like hydrochloric acid will dissociate into ions when dissolved in water, allowing them to conduct an electrical current. Conversely, nonionic compounds such as sugar will not conduct electricity when dissolved in water.

Does the liver make protein?
It creates amino acids which collects mrkhthen the amino acids brake and makes proteins

What allows acids to conduct electric current?
An strong acid strongly conducts electricity because contains a large number of ions. Acids can be described as proton donors, or electron acceptors. These ions, when in water, act as charge carriers and can hence conduct electricity (strong electrolytes).
What are the relative charges on eiter side of the membrane?
The inside of the cell is negatively charged compared to the outside due to an abundance of negative ions such as proteins and nucleic acids inside the cell. This creates an electrical potential across the membrane known as the membrane potential.
