1.) Which of the following is not true of negatively supercoiled DNA?
A. Eases the separation of nucleotide strands during replication and transcription.
B. Allows DNA to be packed into small spaces.
C. Has less than 10 bp per turn of its helix.
D. Is more negatively charged due to additional phosphates per turn of the helix.
E. Is found in most cells.
2.)How many complete rotations would most likely correspond to a positively supercoiled DNA molecule that is 100 bp in length?
A.) 0
B.) 5
C.) 10
D.) 15
E.) 100
Answer:
1.
C. Has less than 10 bp per turn of its helix.
2.
D.) 15
Explanation:
Negatively supercoiled DNA
(deoxyribonucliec acid) is the twisting against the helical conformation which is a twist in a left handed direction that loose and straightens the helix at low twisting stress, and knot the DNA into negative supercoils at high twisting stress.
Supercoiling will occur where the DNA helix must uncoiled for the function of a macromolecular assembly.
Supercoiling allows DNA to be packed into small spaces, It allows for more negative charge and can be found in many cells. But it does not have less than 10 bp per turn of its helix.
15 rotations will correspond positively supercoiled dna molecule of 100base pair.

Beginning with solar energy, detail how transfer of energy drives weather and climate. Be sure to mention how energy transfer affects wind, rain, temperature, and climate.
Answer:
So your answer for this question is weather and climate involves with radiation as the transfer of energy. And the rest is conduction and radiation.
Explanation:
Well solar energy is from the sun and the transfer of energies for heat is convection, conduction and radiation. Now electrically, mechanically is ways actually energy can be transmitted. But for weather and climate energy can be transferred there by radiation energy. And "wind, rain, temperature , and climate" are affected by conduction and radiation.
The solar energy affects climate, wind, rain, temperature as follows:
Solar energy is a renewable form of energy, obtained from the transformation of electromagnetic radiation that comes from the Sun.
The Earth's climate is primarily a manifestation of how solar radiation is absorbed, redistributed in the atmosphere-ocean system, and subsequently re-radiated into outer space.
Climate and weather depends on how this energy is distributed between the atmosphere and the earth's surface.The amount of energy absorbed by the surface depends on latitude, causing pressure changes in the atmosphere and forming wind currents.The abundance of water vapor in the atmosphere leads it to condense in the form of clouds, which, when displaced by the wind, collide with each other and release their liquid content, in what we know as rain.In terms of temperature, the climate is warmer where more energy reaches the surface, and colder where less.Also, atmospheric temperature is about the degree of heat or cold that exists in atmospheric air masses, heated mainly by solar radiation.Therefore, we can conclude that solar energy is the energy source for all life on Earth, where most of the solar energy reaches the surface in the form of light and heat and the climate depends on how this energy is distributed between the atmosphere and the earth's surface.

Ji wants to write an example of a frameshift mutation using the following sentence: THE CAT SAW THE RAT. Which sentence best shows a frameshift mutation?
Answer:
This question lacks options, the options are:
A) THC ATS AWT HER AT
B) CAT THE SAW RAT THE
C) EHT TAC WAS EHT TAR
D) THE THE CAT SAW THE RAT
The answer is A
Explanation:
Mutations are generally any change that occurs to the nucleotide sequence of a gene. However, a FRAMESHIFT Mutation is a kind of mutation that changes/alters the reading frame of the nucleotide sequence. Frameshift mutations are caused when either a DELETION (removal of nucleotides) OR INSERTION (addition of nucleotides) MUTATION occurs.
In this question, Ji wants to write an example of a frameshift mutation using the following sentence: THE CAT SAW THE RAT. A frameshift mutation will delete or add nucleotide bases to the sequence. Hence, the sequence: THC ATS AWT HER AT best represents frameshift mutation because a deletion mutation has altered the reading of the sequence in three's.
Notice that the bases in options B, C and D are still read in three's.
Answer:
THC ATS AWT HER AT.

Which of the following is a characteristic of this act?
A)
It promotes the exploration and use of fossil fuels.
B)
It emphasizes energy quality.
C)
It relies mostly on renewable sources of energy.
D)
It promotes an increase in second-law efficiency.
E)
It has no effect on the environment.
Answer:
b is correct answer in my view I think if it's wrong then Correct me
It promotes the exploration and use of fossil fuels. Therefore, option (A) is correct.
What is The Energy Policy Act of 2005?The Energy Policy Act of 2005 was a controversial legislation that was passed by the US Congress in 2005. It had several provisions that were intended to promote the exploration and use of fossil fuels, such as oil, natural gas, and coal.
These provisions included tax incentives for the production and consumption of fossil fuels, as well as relaxed regulations on the exploration and extraction of these resources. The act was largely seen as a "business-as-usual" proposal, as it did not significantly shift the focus of US energy policy away from fossil fuels and towards renewable energy sources.

They have genetic material from two parents is true about sexual reproduction.
What is sexual reproduction?
Sexual reproduction is the process of combining the genetic information of two individuals of the opposite sex to create new organisms. Genetic information is carried on chromosomes within the nuclei of gametes, which are specialized sex cells.
These gametes are called sperm in males and eggs in females. During sexual reproduction, two gametes participate in a fusion process called fertilization to create a fertilized egg.
The fertilized egg is the progenitor cell of the embryonic offspring and receives half of its DNA from each parent. In humans, the fertilized egg contains 46 chromosomes.
Therefore, They have genetic material from two parents is true about sexual reproduction.

What do bears prefer to eat most
Answer:
only the basic bears
Explanation:
Black bears are very opportunistic eaters. Most of their diet consists of grasses, roots, berries, and insects. They will also eat fish and mammals—including carrion—and easily develop a taste for human foods and garbage.
Alaskan brown bears are opportunistic eaters and will eat almost anything. Their diet consists of berries, flowers, grasses, herbs, and roots. They get their protein from beavers, deer, caribou, salmon, carcasses, and other small mammals.
Polar bears feed mainly on ringed and bearded seals. ... When other food is unavailable, polar bears will eat just about any animal they can get, including reindeer, small rodents, seabirds, waterfowl, fish, eggs, vegetation (including kelp), berries, and human garbage.
A panda's daily diet consists almost entirely of the leaves, stems and shoots of various bamboo species. Bamboo contains very little nutritional value so pandas must eat 12-38kg every day to meet their energy needs.

C.)More drinking water will become available.
D.) Native Inuit peoples will become extinct.
The answer is A I took the k12 test
A predicted result of the melting of the world's ice sheets is option "A" that is Sea levels around the world may rise.
How does melting ice sheets affect climate change?When warming temperatures slowly liquefy sea ice over the period, more periodic bright covers are open to reflect sunlight back into the atmosphere.
More solar energy is soaked at the surface and ocean temperatures rise. This starts a process of warming and melting.
Thus, option "A" that is Sea levels around the world may rise.

Using the data from the paraquat experiment, explain how you know that paraquat did not cause the coral bleaching.
Answer:
paraquat is a herbicide.
Explanation:
Paraquat did not cause the coral bleaching because paraquat is a herbicide which is used to kill weeds not algae. We know that coral have small algae attached to its body which is responsible for its colour so if we apply paraquat, it does not kill the algae and so coral bleaching did not occur. if we apply another chemical which kills algae so it causes coral bleaching and the coral becomes white.
