Answer:
Amino acids are molecules used to build proteins. All amino acids have a central carbon atom surrounded by a hydrogen atom, a carboxyl group (COOH), an amino group (NH2), and an R-group. It is the R-group or side chain that makes each of the 20 amino acids unique.

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.

When the level of sugar in the blood is too high the excess sugar is stored in the
muscle to be used later as needed. Which characteristic of life is described here?
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).

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.

Answer:
Triclosan was popularly utilized as biocide generally in present modern items like oral, cosmetics, and dermal items this expanded utilization causes microbial resistance among intestinal, dermal, and ecological generally E.coli and Salmonella enterica.
This microbial resistance happens because of moving out of metabolites, target modification or alteration, development of Biofilm, and bypass of metabolic blockage in the bacterial cells additionally acquires opposition against triclosan.
This causes serious endless supply of the items and prompts utilization of these biocides and ineffective.This is expected to acquiring cross resistance or co-resistance from the antimicrobial.

The definition of manipulated variable ?
A manipulated variable is an independent variable subject to the changes of an experiment to analyze its effect on a dependent variable. Simply put, the variable is modified to assess its influence over the experiment’s overall result. It’s called “manipulated” because it’s the one you can change. In other words, you can decide ahead of time to increase it or decrease it. In an experiment you should only have one manipulated variable at a time.

Are flowers naturally rainbow colored? Please describe how the store can
have a rainbow colored plant (using the terms xylem or phloem.)
Answer:
Answer in explanation
Explanation:
Capillary action: Inside the stem, there are tube-like transport tissue, called xylem, that brings water and nutrient to different parts of the plant. Water molecules are attracted to the surface of the xylem cells by weak electrical attractions. This sticky property is called adhesion. Water automatically moves up the xylem due to adhesion and the resulting movement is called capillary action1.
Cohesion: Water molecules are not only attracted to the surface of xylem (adhesion), but they are also attracted to one another. This property is called cohesion. Because of cohesion, water molecules fill the column in the xylem as they move up and act as a continuous stream of water.
Transpiration: Water evaporates from the plant through transpiration. As water evaporates in the petals or any part of the plant exposed to air, a negative pressure is created in the xylem, resulting in suction pulling the water upward just like you draw water upward when you suck on a straw.
