The option are not given and the options are:
Proteins are denatured by breaking covalent bonds.
Linear molecules like DNA are inherently stable.
Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.
The statement is incorrect; it actually takes far more energy to denature proteins than it does to denature DNA.
Answer:
The correct answer is- Individual hydrogen bonds may be weak, but DNA structure is stabilized by many thousands or millions of these bonds - far more than found in proteins.
Explanation:
Proteins become denatured when it looses its three-dimensional structure. Disulfide bond and hydrogen helps in stabilizing the three-dimensional structure of proteins and if these bonds break due to any factor protein lost its structure and function.
DNA is made up of a large amount of hydrogen bond because in AT base-pairing two hydrogen bonds are required and in GC base pairing three hydrogen bonds are required. Therefore it can be concluded that as more hydrogen bonds stabilizes DNA than protein its melting temperature is higher than protein.
I would say A.
B and C can be eliminated because they have to do with using resources more efficiently. Now we're down to A and D, and of the two, I'd say A is most plausible. Globalization is the connection of the world with each other. With all this technology, companies see endless possibilities to sell their products. They use more and more natural resources, which can deplete those resources quickly.
Hibernate because when they sleep they don't use any calories so thus,they can survive the winter without waking up for food. This is because also their metabolism slows down so much that it consumes little to no calories a hour keeping its vitals stable and not having to wake up to ''refuel" it's self.
Answer:
D. it is not true reproduction as a host cell is required to build new viruses
Explanation:
Viruses reproduce by using host cells to convert them into that virus. That is how they spread throughout your body.
Answer:
D. Bees benefit from drinking nectar from flowers, and the flowers are pollinated.
Explanation:
Mutualism is when two different living things <u>benefit</u> from each other. When bees drink nectar from flowers, they are benefitting from that because they get nectar. The flowers are also benefitting from this because they are being pollinated.
A. is incorrect because the grass does not benefit
B. is incorrect because the dead animals are dead so they don't benefit from this
C. is incorrect because the fish are harmed and do not benefit from this
Therefore, the only correct answer is D.
