Answer: carry out all basic life activities

Explanation:

Bacteria are the simplest single celled prokaryotic organisms. They do not posses a well define nucleus. They do not posses membrane bound nucleus and other organelles. Although these organisms are simple but carry out all basic life activities like respiration, digestion and reproduction are common to all bacterial cells but some bacterial cells undergoes photosynthesis and chemosynthesis to synthesize their own food.

Which of the following characteristics, structures, or processes is common to both bacteria and viruses? A. Metabolism B. Riboso

Darina [25.2K]

Answer:

C. Genetic material composed of nucleic acid

Explanation:

The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.

The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.

A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The

yanalaym [24]

Answer:

Placing salty water in A and distilled water in B.

Explanation:

The fastest net rate of water movement into the A-side will occur if we place salty water on that side and distilled water in the other one. The reason for this is that the A-side contains a higher concentration of solute than B. So, the water will pass the semipermeable membrane and go to the A-side to valance the concentrations on both sides. As we can see, there is an increase in the net rate of water movement into A.

Rosa drew a diagram to compare substitution mutations and insertion mutations.

djverab [1.8K]

<h2>Hey There!</h2><h2>_____________________________________</h2><h2>Answer:</h2>

$\huge\boxed{Option A}$

<h2>_____________________________________</h2><h2>Mutations:</h2>

Mutations are the changes produced in the nucleotide sequence of the genome.

There are four main types of mutations

Substitution

Insertion

Deletion

Duplication.

<h2>_____________________________________</h2><h3>DELETION:</h3>

A small segment of chromosome mat be missing. This condition is known as deletion.

For example, Normal chromosome has A B C D E F G. If deletion mutation occurs then mutated chromosome has A D E F G and B C got deleted.

<h2>_____________________________________</h2><h3>DUPLICATION:</h3>

In this condition, a part of chromosome present in exec ess to the normal chromosome.

For example, Normal Chromosome has A B C D E F G. If duplication mutation occurs, then mutated chromosome had A B C B C D E F G and B C is duplicated.

<h2>_____________________________________</h2><h3>SUBSTITUTION MUTATION:</h3>

Substitution is a type of mutation where one base pair is replaced by a different base pair.

For example, in the sequence CAAGT, if C replaces G, it is a substitution mutation.

<h3>INSERTION MUTATION:</h3>

In genetics, an insertion is the addition of one or more nucleotide base pairs into a DNA sequence.

For example, in the sequence CAAGT, if extra base G gets inserted after C, the new sequence would be CGAAGT.

Both substitution and insertion mutations change the position of nucleotide thus, the type of amino acid.

Peter consumes no commodities other than miller lite and bud light. his annual budget for these two commodities is described by

liq [111]

The answer Peter will consume 60 sixpacks of Miller lite per year.

The solution for this problem is:

The cost of 6 Miller six packs is 5 * 6 = 30.

Then the cost of 2 Bud cases is 30 * 2 = 60.

Consequently, Miller is low-priced so Peter will buy as much Miller as possible. Therefore, <span><span>300 which is the budget divided by 5 is the cost for the Miller sixpacks = 60</span></span>
