Answer: True
Explanation:
Just like digital information the genetic information is stored, retrieved, processed and translated by the cell
Both of them are similar in some ways like the hard drive is similar to the DNA whilst the words are to protein, bytes to condon, bits to nucleotides, the letters to the amino acids and the ASCII table is similar to the condon table.
But the simplest operational cell is still more complex than a computer. If you get one thing wrong in the code the whole program will crash but if the same happens in the DNA it may just turn out to be better.
b.Na+ and K+ leaks
c.Na+ cotransporter
d.Na+-K+ ATPase
The Na+-K+ ATPase, a membrane protein pump, prevents the sodium (Na+) and potassium (K+) gradients from dissipating by actively transporting these ions against their concentration gradients.
The mechanism that prevents the Na+ and K+ gradients from dissipating is the Na+-K+ ATPase. This is an integral membrane protein pump found in almost all animal cell membranes. This pump carries out the function of moving 3 sodium ions out of the cell and 2 potassium ions into the cell during each cycle of pumping. This is done at the expense of one ATP (adenosine triphosphate) molecule, hence the name ATPase. This active transport work against the concentration gradients of these ions, hence maintaining their respective gradients across the cell membrane.

b. runoff
c. ice and snowpacks
d. all of the above
Answer:
d. all of the above
Explanation:
Rivers are formed by abundant amounts of water going down uneven terrain.
They can originate from any of the forms detailed in the options. The abundant precipitations or unmelting of snowy peaks can concentrate large masses of water that can then form rivers or runoffs.
Runoffs are formed by the accumulation of water on a land that is saturated and can not absorb more water.
Ok so in this experiment what we want to find is the catalyst for the reaction. Our original reaction is the following. A + B --> C, therefore to find which of the unknown substances (X, Y, and Z) is the catalyst reaction we simply have to do the following:
A + B + X --> C
A + B + Y --> C
A + B + Z --> C
The reaction that produces C much faster than our original reaction A + B --> C will be our catalyst. The reason being that one of the substances will increase the rate of the chemical reaction.
I hope it helps, Regards.
Answer:
Prepare three test tubes containing reactant A.
Prepare three test tubes containing reactant B.
Add one test tube of reactant B and one unknown to one test tube of reactant A. Repeat for the other two unknowns.
Time the reaction until bubbling stops.
The unknown that causes the reaction to occur the quickest is the catalyst.
I took the test
Both viruses and animal cells possess genetic material in the form of nucleic acids.
Viruses are infectious agents that consist of genetic material (either DNA or RNA) enclosed within a protein coat called a capsid. Some viruses also have an outer envelope derived from the host cell's membrane. Viruses lack cellular structures and cannot carry out essential life processes on their own. They depend on host cells to replicate and produce new viral particles.
Animal cells, on the other hand, are the fundamental units of structure and function in animals. They contain a nucleus that houses the genetic material, which is composed of DNA. Animal cells also possess various organelles and structures that carry out specific functions within the cell.
Despite their fundamental differences, viruses and animal cells both have genetic material in the form of nucleic acids. However, it is important to note that while animal cells use their genetic material to carry out the necessary functions of life, viruses rely on host cells to replicate and produce new viral particles.

The correct option is D.
A virus refers to an infectious micro organism that is made up of nucleic acid molecule that is enclosed within a protein coat. Viruses are only able to reproduce and multiply when they come in contact with living cells, in the absence of living cells they remain dormant and they do not show any sign of been a living thing. The nuclei acid molecule of a virus can be in form of a DNA molecule or a RNA molecule.
Answer: The answer is D/RNA or DNA core surrounded by a protein coat.
Explanation: One reason a virus is considered to be a particle rather than a cell is because structurally it is only a RNA or DNA core surrounded by a protein coat. It has none of the other features of bacterial cells.
