1. outer covering - none of the other answers can occur due to the absorbed solutions inability to reach the centre of the organism, smaller cells in greater numbers are more efficient as they can group together yet all absorb the right amounts of nutrients for its need. multi cellular organisms, such as humans can have the other answers in them as cells group together to make skin, muscles and organs. it also gives the organism to grow larger.
2. bacteria are single celled. bacteria reproduce through mitosis (cell division). bacteria break down decaying matter to obtain energy. every organism requires energy to live. Bacteria can move in order to reach their nutrient source.
Answer:
<u>D) the nucleic acid (either DNA or RNA)</u>
<u />
Explanation:
Phages, or bacteriophages are viruses that infect bacteria.They have varying shapes, and sizes, and may contain one of two kinds of nucleic acid; these are RNA and DNA.
The nucleic acids are made up of nucleotides. These are genetic storage biomolecules made up of the monomers ribonucleic acid (RNA) deoxyribonucleic acid (DNA).
Answer:
Answer is Ammonium sulfate.
Explanation:
The method of adding ammonium sulfate to a protein solution is known as precipitation. This is because the addition of ammonium sulfate will reduce or decrease the solubility of the protein. And as the ammonium sulfate is being increased, so also the solubility of the protein will be decreasing.
And at the long run, the protein will be precipitated. This is what is referred to as the 'salting out' procedure.
<u><em>Answer:</em></u>
<u><em>The correct option is </em></u><u><em>A</em></u>
Explanation:

In the given situation, the payback period decreases as the electricity cost increases, i.e., option C is correct.
<h3>What is payback period?</h3>
The payback period is the amount of time required to recover the cost of an investment or to reach the breakeven point for an investor.
Shorter payback periods indicate more appealing investments, whereas longer payback periods indicate less desirable investments.
In the given situation, the payback period decreases as the electricity cost increases.
Thus, the correct option is C.
