Term “plant system” when referring to individual plants is sgnificant because _____ ?
a plant represents a species
thinking of a single plant as a plant system reminds us of the complexity of plant life
some plants fit into greater ecologies
commercial growers have developed large systems of plants that can be grown together
Answer:
Thinking of a single plant as a plant system reminds us of the complexity of plant life
Explanation:
A plant system is a plant and all of its parts. This lets us know that there is an entire system within each plant, allowing it to carry out functions and live. We often take for granted the complexity of lifeforms, especially plants.

2. A researcher adds an enzyme to a sample of human DNA to see if the
DNA changes. Which result would best support the conclusion that the
enzyme had no effect on the DNA?
The DNA has uracil bases.
The DNA has unpaired nitrogenous bases.
The DNA has a single strand with nucleotides and a sugar-phosphate backbone.
The DNA has a double helix shape with nucleotide pairs and sugar-phosphate
backbones.
Answer:
has a single strand with nucleotide and a sugar phosphate backbone
Answer:
hi
i'm not really sure but i think its the second option
Explanation:
enzymes when they are active usually hydrolyzes things
so in the second one we read that we can see unpaired nitrogenous bases
these bases are:
adenin timin citosin goanin
those are for DNA . in RNA timin is changed with uracil
so these means the hydrogen bond between them are hydrolyzed by enzyme
so we see the effect of enzyme on DNA
DNA and RNA are made of what monomers? ___________________________
42. What are the 3 components of a nucleotide? ________________________________________
43. What are the elements found in nucleic acids?___________________________________
44. What are the 3 polymers for nucleic acids.________________________________________
45. What are the 2 main functions for nucleic acids.________________________________________________________________________
Answer:
42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine
Explanation:
43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.
44.polymer of nucleic acid
33 terms. The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Threose nucleic acid (TNA) is an artificial genetic polymer in which the natural five-carbon ribose sugar found in RNA has been replaced by an unnatural four-carbon threose sugar.

Which function of the integumentary system is illustrated in the release of sweat? A. Absorption B. Protection C. Sensory Reception D. Regulation E. Secretion F. Both regulation and secretion
Answer:
F. Both regulation and secretion
Explanation:
Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.
The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

Answer:
The correct answer is:
Archaea
Explanation:
took the test :)
Archaea is the organism that is classified by the scientist.
The correct option is A.
What is an Archaea?They are single-celled prokaryotic organisms of the domain Archaea.
They are separated from bacteria due to the difference in the composition of the cell walls.
These organisms reproduce by binary fission.

What is the force of a 3kg skateboard accelerating at a rate if 4m/s²? Plug the numbers into the formula
Answer:
[tex]\boxed {\boxed {\sf 12 \ Newtons }}[/tex]
Explanation:
Force is the product of mass and acceleration.
[tex]F=ma[/tex]
The mass is 3 kilograms and the acceleration is 4 meters per square second.
[tex]m= 3 \ kg \\a= 4 \ m/s^2[/tex]
Substitute the values into the formula.
[tex]F= 3 \ kg * 4 \ m/s^2[/tex]
Multiply.
[tex]F= 12 \ kg*m/s^2[/tex]
1 kilogram meter per square second is equal to 1 Newton. Our answer of 12 kg*m/s² is equal to 12 N[tex]F= 12 \ N[/tex]
The force of the skateboard is 12 Newtons.

Explain how an biotic factor (stronger storms, warmer oceans, or lower ocean pH) can affect populations in a coral reef ecosystem
Not only is the biota important, but the abiotic factors in the ocean are also important because both groups work together. The abiotic factors in the ocean help the ocean to 'work'. For example, phytoplankton (autotrophs) need light, nutrients, CO2 (dissolved gases) to photosynthesize.
Answer:
Biotic factors include plants, animals, and microbes; important abiotic factors include the amount of sunlight in the ecosystem, the amount of oxygen and nutrients dissolved in the water, proximity to land, depth, and temperature. Sunlight is one the most important abiotic factors for marine ecosystems.
Explanation:
An offspring cannot have a trait if neither of its parents have it. Do you agree or disagree with this statement now? What evidence supports your ideas about the statement?
No
An offspring can have traits that neither parents have. People have both dominant and recessive genes that control the traits that they have. So the child would have gotten two recessive genes that the parents carry, to display a trait that the parents don’t display.
It can be carried to you when the chromosomes combine even if the parents don't possess the same trait. It can skip and be dominant for you, so you would be able to see it in your genetic make up.
No, I don't agree with this statement.

can dogs the poison ivy?
Explanation:
Though cases of a dog being affected by poison ivy are rare, if you have a canine companion with sensitive skin, you should keep him away from the plant, just in case. “After being in an area with poison ivy or oak, you should wash your dog,” Nold suggests.
Answer:
Unfortunately, yes, your dog can get poison ivy. Fortunately, dogs getting poison ivy is not as common as it is in humans. It is tougher for poison ivy to make contact with the dog's skin since they are covered in protective fur. If your dog does get poison ivy it is easily treatable.

Calculate the population of 217 bison at the end of 2 years if it decreases at a rate of 7.5% per year. _____ bison
7.5% of 217 = 16.275
At end of 1 year bisons = 217 - 16.275 = 200.725
7.5% of 200.725 = 15.054375
At end of 2 years bisons = 200.725 - 15.054375 = 185.670625 (Rounding that to the tens)

Red-green colorblindness is an X-
linked recessive trait that
prevents the eye from
differentiating red and green
colors. Look at the pictures. What
problems could a person
experience as a result of
perceiving the colors so similarly?
Answer:
look,Examples of X-linked recessive conditions include red-green color blindness and hemophilia A: Red-green color blindness. Red-green color blindness means that a person cannot distinguish shades of red and green (usually blue-green), but their ability to see is normal.
Red-green colorblindness is an X-linked recessive disorder in humans.
What do you mean by disorder?An illness that disturbs the normal physical or mental functions of any individual.
The allele of colorblindness resides on X-chromosome, which means the male is affected with one mutant allele. while both the alleles are required to be mutant to cause the disorder in females. Another example of X-linked disorder includes Hemophilia. Red-green colorblindness reveals that an individual cannot able to differentiate the shades of red and green but occupy the normal vision.
Therefore, Red-green color blindness is an X-linked recessive disorder in humans.
