Explanation:
The four nitrogenous bases are A, T, C, and G. They stand for adenine, thymine, cytosine, and guanine. ... Adenine always pairs with thymine, and cytosine always pairs with guanine. The pairing nature of DNA is useful because it allows for easier replication.

Create a mutant fly with any number of variations and mate it with a
wild-type fly. How many offspring are wild-type? What are the
phenotypes of the flies that are not wild-type?
Untamed type, a person who exhibits the typical phenotype, which is the phenotype typically present in a population of living things. Mutant, a person who deviates from the typical phenotype in some way.
What are the phenotypes of the flies that are not wild-type?The phenotypic of a species' normal form as it appears in nature is known as the wild type (WT). The wild type was initially thought to result from the “regular” standard allele at a location, as opposed to a non-standard, “mutant” allele.
Type wild, an individual with the typical phenotype, or the phenotype typically present in a population of living things in the wild. Mutant, a person, has a phenotype that is different from the typical phenotype.
Therefore, to characterize a gene in its natural, unaltered (unchanged), non-mutated form. Some cancer types have been linked to mutated (changed) versions of specific genes.

Which of the atomic models represents the most reactive element?
A. Argon, because it has three energy levels with eight electrons in the third level.
B. Lithium, because it has two energy levels with one electron in the second level.
C. Aluminum, because it has five energy levels with two electrons in the third level.
D. Carbon, because it has two energy levels with four electrons in the second level.
The most reactive element is represented by the atomic model for lithium, which consists of two energy levels with an electron in the second level. So, the correct option is B.
What is Reactive element?A reactive element is one that forms chemical bonds with other elements to obtain a stable electron configuration. Reactive elements are chemically unstable. The amount of valence electrons in an element's highest energy level determines how reactive it is.
The element with the fewest number of energy levels and most reactive valence electrons in the above example is lithium, which has only two energy levels and one electron in the second level. Lithium in this state has one valence electron, which makes it very reactive and predisposed to form bonds with other elements filling its outermost shell.
Therefore, the correct option is B.

A team of students from UGA are completing a field study to determine the impact the American alligator has on ecosystems in places such as the Okefenokee Swamp in South Georgia over a 3-month period. In one area, they have removed the alligators and in another area they have left the alligators. What is the hypothesis the students are testing?
A.
If the American alligator is a keystone species, then the ecosystem with alligators absent will be healthier and contain greater biodiversity.
B.
If the American alligator is a keystone species, then the ecosystem with alligators present will be healthier and contain greater biodiversity.
C.
If the American alligator is a tertiary consumer, then the ecosystem with alligators present will contain fewer primary producers.

How is antibiotic resistance related to Natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Animal body systems often coordinate their actions to carry out specific functions for the whole animal. Which of these correctly describes the interaction of two biological systems for a specific purpose in the human body?
Answer: I believe c is what you're looking for, D is also a viable option, but C is more likely.
Explanation:
The integumentary and immune system correctly describes the interaction
of two biological systems for a specific purpose in the human body.
The integumentary system which comprises of the skin, hair and nails help in
the protection and prevention of foreign substances from entering into the
body.
In situations where there is a cut or pathogenic microorganisms being
present in the body then the immune system acts by production of
antibodies which fight them.
The two systems work hand in hand to protect the body from foreign
compounds or organisms which may cause illness and death.

what happened when you simulated wave movements in your oil spill model. what affect would this have on resource availability for organisms that live near or around the shore
Answer:
Wave movement started to move the oil around in the water mixing it a little bit, but not very much. Wave movement also brought the oil near the shorelines. This could affect organisms that live around the shoreline because many organisms will catch hypothermia and most likely die if not treated.

Creepers and climbers have thin, slender stems and cannot stand upright on their own.
Climbers, such as jasmine, grapevine, and money plant, require external support to grow vertically. Creepers, such as watermelon and pumpkin, grow horizontally on the ground.
A grapevine, also known as a grape, is a stem-tendril climber plant with cascading growth that grows in an upward direction.
Every year, new shoots emerge from this plant. It is grown to a height of 19 meters or more, depending on the pruning technique used.

Answer:
Reasons for the spreading of this illness is due to the fact that people are not wearing their masks, not covering their coughs and sneezing which spreads germs, and during this time coming in close contact with others. To help prevent the spread would be for us to wear masks because not only does it protect us it helps protects people from our germs. Washing hands and covering coughs and sneezes can also help tremendously as well as keeping distance between others. The sooner we all practices these basic things the quicker all of us can get back to our normal lives because almost we know almost everyone misses the normal.
