Answer:
Bacterial DNA is a double-stranded helix that has to separate its strands during replication. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed by DNA gyrase. Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the deadly bacteria from growing.
Explanation:
DNA which stands for deoxyribonucleic acid is the molecules that stores genetic information in most living organisms. For successive reproduction to take place as well as growth to occurs in organisms, the genetic information stored in the DNA must be copied into new cells. This is achieved through the process of DNA replication.
DNA is a double-stranded molecule that is helical in shape. For replication to occur, the double strands has to be separated so that the information stored within can be accessed and then copied. DNA helicases are enzymes which are essential during DNA replication because they separate double-stranded DNA into single strands allowing each strand to be copied. The unwinding of DNA strands at the replication fork creates twists farther down the helix that need to be relaxed otherwise, the DNA strands will break. The enzyme responsible for relaxation these twists is known as DNA gyrase. Thus, any drug like Ciprofloxacin than inhibits DNA gyrase will block the DNA replication process in bacteria thereby stopping the growth of the bacteria.
Bacterial DNA is a double-stranded helix that has to separate its strands
during replication. The unwinding of DNA strands at the replication fork
creates twists farther down the helix that need to be relaxed by DNA gyrase.
Ciprofloxacin inhibits this enzyme to block DNA synthesis and stop the
deadly bacteria from growing.
The antibiotic referred to as Ciprofloxacin acts on the DNA of the bacteria
and it does this by inhibiting the enzyme that is required for DNA
synthesis. This stops replication and the anthrax bacteria from growing and
forming new organisms.

Explain E.O. Wilson's theory of Island Biogeography as it applies to environments other than islands physically
surrounded by water.
Answer:
The theory of E.O. Wilson's theory of Island Biogeography was originally developed as island biogeography, to explain species richness of actual islands, surrounded by water.
It proposes that the number of species found in an undisturbed environment is determined by immigration and emigration. According to him, the species richness will be the same if this island will have an equal number of the immigration and extinction or emigration of species.

which scenario would lead to the biggest increase in rabbit population?
increase in food supply and decrease in predators.
increase in food supply and predators.
decrease in food supply and increase in predators.
decrease in food supply and predators.
The scenario that would lead to the greatest increase in the rabbit population is increased food supply and decreased predators.
What are predatory animals?Predatory animals are animals that feed on other animals. They occupy the top of the food chain and are therefore found in smaller numbers. Predators are usually large, agile and adapted for hunting. A good predator is not known just by its size.
With this information, we can conclude that the scenario that would lead to the greatest increase in the rabbit population is increased food supply and decreased predators.

6. Compare the DNA of an offspring to the DNA of its parents.
Answer: In DNA the parent duplicates itself through a process known as mitosis. Any offspring is going to have the same exact DNA as the parent. (same characteristics, everything).
The comparison of the DNA of an offspring to the DNA of its parents is determined by the fact that every offspring gets 50% of its genome from each parent, but it is always a different 50%.
How does the DNA of parents compare to that of offspring?In the process of sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote. In other words, an offspring inherits half of the genetic material from each parent. The children resemble their parents, but they are not identical to them.
During the process of meiosis, gametes get a random chromosome from each pair. This means that there are over 8 million possible DNA combinations from 23 chromosome sets. Due to this, the difference in the genetic material or DNA sequences is occurred due to the process of variations between them while DNA copying.
Therefore, the comparison is made due to the mechanism through which every offspring gets 50% of its genome from each parent, but it is always a different 50%.

Answer:
A. Destruction of terrestrial biota
Explanation:
all the other answers would decrease the carbon output. thickening of ocean sediments reinforces a carbon reservoir (which stores carbon), reduction in the use of fossil fuels would reduce the amount of carbon emissions, increase in marine biota = increase in carbon storage because marine biota is also a carbon reservoir.
Destruction of terrestrial biota would cause excess output because terrestrial biota is a carbon reservoir, and all of that carbon would be released into the carbon cycle.

Explanation:
Carbon-14 has 8 neutrons and 6 protons. When this radioisotope undergoes the radioactive decay process it becomes nitrogen-14.
The number of protons in nitrogen-14 is?
Answer:
Nº of protons = Atomic number → 7Nº of neutrons = Massic number - Atomic number → 14 - 6 = 7Explanation:
Probably, you will find it useful to know how to deduct this information for any other isotope.
To interpreter the representation of an isotope, you need to know that the symbol representing the isotopes is the same as the chemical element. The representation also includes a superior number that indicates the massic number, and an inferior number that indicates the atomic number.
Isotope representation ⇒ ⁰ X ₙ
Where
X is the element o is the massic number, which is defined as the sum of the number of protons and the number of neutrons. n is the atomic number, which is the number of protons.(Note: You can also find the O symbol as m symbol. Both represent the same massic number)
When protons, neutrons, and electrons get together to form an atom, they lose part of their mass as energy. This is why the atomic weight is slightly inferior to the sum of masses.
In the periodic table, there is only one value of atomic mass, which belongs to the media mass of isotopes pondered by their abundance in nature.
So, what you need to know is that
Nº of protons = Atomic number → nNº of neutrons = Massic number - Atomic number → o - n (or m - n)Nº of Electrons = Nº of protons = Atomic number → nCarbon-14 forms in the atmosphere, it is radioactive and unstable. When they emit an electron and an antineutrino, they become Nitrogen-14.
Isotope representation ⇒ ¹⁴ C ₆
Massic number = 14Atomic number = 6So, from this information we can assume that
Nº of protons = Atomic number → 6Nº of neutrons = Massic number - Atomic number → 14 - 6 = 8 Nº of Electrons = Nº of protons = Atomic number → 6So, from this information we can assume that
Massic number = 14Atomic number = 6The same reasoning can be used to determine the number of protons and neutrons of nitrogen-14.
Isotope representation ⇒ ¹⁴ N ₇
Massic number = 14Atomic number = 7So, from this information, we can assume that
Nº of protons = Atomic number → 7Nº of neutrons = Massic number - Atomic number → 14 - 6 = 7 Nº of Electrons = Nº of protons = Atomic number → 7

The overall efficiency of oxidative phosphorylation, assuming standard conditions, can be calculated by comparing the free energy potentially available from the oxidation of NADH by O2 to the free energy required to synthesize 2.5 ATP from 2.5 ADP. This comparison reveals an efficiency of 35%, which is based on the experimental measurement of 2.5 ATP for every NADH oxidized during oxidative phosphorylation. Using this efficiency, calculate the number of ATP generated by each of the following Complexes:
Answer:
The number of ATPs produced wheh efficiency is 100% is 71.42 ATP.
Explanation:
It is known that at the end of Kreb's cycle 10 NADH are produced
Now by using the unitary method
1 NADH produces=2.5 ATP
10 NADH produces=2.5 ATP x 10
10 NADH produces=25 ATP
This is for the efficiency of 35%.
35% efficiency produces ATPS=25
1% efficiency produced ATP=[tex]\dfrac{25}{35}[/tex]
100% efficiency produced ATP=[tex]\dfrac{25}{35}\times 100[/tex]
100% efficiency produced ATP=71.42 ATP
The number of ATPs produced wheh efficiency is 100% is 71.42 ATP.
