Question 5
Ultraviolet (UV) radiation can damage DNA by breaking weak bonds. Which of the following best explains how this occurs?
A
UV radiation disrupts the double helix structure by breaking the covalent bonds between the nitrogenous base pairs,
B
UV radiation disrupts the double helix structure to breaking the hydrogen bonds between the nitrogenous base pairs.
С
UV radiation is able to break DNA strands in two by breaking covalent bonds between the sugar phosphate backbone molecules
D
UV radiation is able to break DNA strands in two by breaking hydrogen bonds between the sugar phosphate bachoone molecules
UV radiation disrupts the double helix structure to breaking the hydrogen bonds between the nitrogenous base pairs.
WHAT IS DNA?
DNA, known as deoxyribonucleic acid, is one of the two types of nucleic acids. It is a long double helical structure found in the nucleus of cells.STRUCTURE OF THE DNA:
The DNA is made up of nucleotides. Each nucleotide consists of three components namely: phosphate group, nitrogenous bases and a pentose sugar. In the DNA molecule, the four nitrogenous bases are Adenine, Cytosine, Guanine and Thymine. Adenine and Thymine bonds together while Cytosine and Guanine bonds together. Weak hydrogen bonds holds one nitrogenous base to its complementary base.Therefore, an ultraviolet radiation can damage the DNA structure by breaking the hydrogen bonds between the nitrogenous base pairs.

(Choice D)
D
None of these labeled structures would be the site of the malfunctioning proteins.
Answer:
Structure A
Explanation:
Malfunction proteins happen when it changes the instructions for a gene to make a protein. This change or "malfunction" can disrupt any protein and cause not to work at all. When in a mutation occurs and changes the protein, it can change the development and cause serious medical conditions for a person.

Which organisms obtain energy from dead or decaying matter? Check all that apply. groundhogs.
daisies
earthworms
bacteria
humans
phytoplankton
Answer:
The correct answer is Earthworms, and Bacteria.
Hope this helps :)
Explanation:
I just took the test on edge.
Decomposers are the organisms which feeds on dead and decaying matter. Earthworm and bacteria are included under decomposers.
What are Decomposers?Organisms that feeds on dead or decaying organisms and return organic material again to ecological cycle.
These are also called as detritivores. If decomposers gets vanished from ecology then it will result in stopped recycling of carbon and hence affect percentage of carbon dioxide in environment.
Some organisms that comes under this category are bacteria, earthworm, fungi, invertebrates, some insects etc.
Thus, the correct options are b and c.

Describe the basic structure and functions of proteins.
Answer:
Each protein is made up of a unique number and order of amino acids. The protein that is created has a specific job to do or a specific tissue such as muscle tissue to create. The structure of amino acids is fairly simple. Each amino acid has an amino group at its core with a carboxyl group and a side chain attached.

What is migration ?Migration can be defined as the movement of a large number of organisms from one place to another place, there are many reasons for migration.
The term migration is used to define regular and periodic movements of the population away from or back to their place of origin, it can be up different types.
Some migration can occur for an entire lifetime and it happens to be a single migration of an individual. This is in the case for the Pacific salmon. On another hand, an individual may migrate frequently, like many of the migratory birds and other mammals.

A. Ability to evolve
B. Use of energy
C. Maintaining an internal balance
D. Response to environment
Why are answer choice B is incorrect? Include in your response an explanation or
example of the incorrect choices. *
Your answer
Answer:
B
Explanation:
The characteristic of life is described in order to make reference that the glucose is stored in the muscle to be used later is MAINTAINING an internal balance (Option C).
Homeostasis refers to the functions of the body that work to maintain internal environmental conditions relatively constant.Insulin and glucagon are fundamental hormones that help to control sugar levels in the blood and thus maintain this homeostatic state.In muscle, glucose (sugar) is stored as glycogen.Glycogen is a polysaccharide composed of many subunits (monomers) of glucose.
In conclusion, the characteristic of life is described in order to make reference that the glucose is stored in the muscle to be used later is MAINTAINING an internal balance (Option C).
