<h3><u>Answer;</u></h3>
All four organisms have exactly the same components in their DNA, but it varies in number and sequence
<h3><u>Explanation;</u></h3>
- <em><u>DNA, known as deoxyribonucleic acid is a type of nucleic acid which is important to all living organisms as it helps store genetic information.</u></em>
- <em><u>All living organisms store their genetic information using DNA molecules or RNA molecules. Most organisms contains DNA that have similar components, however their DNA will differ in number and also the sequences. </u></em>
- <em><u>The similarity between the molecules of DNA indicates a common ancestry among organisms. </u></em>
Answer: The answer is D. There Would be a general decrease in the Ultrviolet radiation experienced by Earth
Explanation: I took the Study Island quiz and i got it Correct
The antibiotic called ampicillin was not effective against E.coli.
Answer: D
Explanation:
E.coli is normal microbial flora which is present in the gut of the mammals.
It is gram negative bacteria and very few strains of this bacteria causes harm.
Antibiotics are the chemical drugs which are used to treat the microbial infection either by killing the causative organism or by its growth inhibition.
Antibiotics such as neomycin, penicillin and erythromycin are usually used to treat E.coli infection.
Antibiotic such as Ampicillin is not used as the bacterium E.coli is highly resistant to it.
The organism can produce 12 genetically different gametes.
<h3><u>Explanation:</u></h3>
The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.
Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.
Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.
So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
