Answer:
4
Explanation:
There are 4 nitrogenous bases and they are Adenine, Thymine, Cytosine and Guanine (in RNA, Thymine is replaced by Uracil)
Answer:
Four different types of nitrogenous bases are found in DNA: adenine (A), thymine (T), cytosine (C), and guanine (G).
Explanation:
DNA is a polynucleotide. Each nucleotide is made up of deoxyribose sugar, a phosphate group and nitrogenous base. In DNA, there are four main kinds of nitrogenous bases. Adenine (A), guanine (G), thymine (T), and cytosine (C) are the four bases of DNA (C). Purine bases are adenine and guanine, whereas pyrimidine bases are thymine and cytosine. Base pairing occurs between complementary bases on two strands of double-stranded DNA. By two and three hydrogen bonds, A and G link with T and C, respectively. In RNA, uracil is present instead of thymine.

As a result of the general stress response, blood concentrations of epinephrine.
Answer:
THE STRESS RESPONSE. Increased concentrations of cortisol, glucagon, and epinephrine serve to increase blood glucose levels and to redirect metabolism so as to increase concentrations of fuel substrates. Finally, there appears to be a tendency towards hypercoagulability, which would likely improve hemostasis.
Explanation:
Dose this help you?
As a result of the general stress response, blood concentrations of epinephrine and cortisol rise.
What metabolic changes occur during the stress response?When the body is under stress, the hormone cortisol, stress and steroid, is released. As a result, the body's sugar level rises, and the extra sugar aids in tissue healing.
Adrenaline is another name for epinephrine. It is a hormone used in medication. When the body experiences an emergency, this is released. When something unexpected happens, like getting stung or bitten by a dog, taking medicine, etc.
They come with charges that include faster heartbeats, higher blood sugar, and improved accuracy.
Therefore, blood concentrations of epinephrine and cortisol increase during the stress response.

What does the Theory of Evolution state and what are the 4 evidences for it? *
Answer:
Mark me brainliest please I really need itExplanation:
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species are related and gradually chamge over time.Darwin's theory consisted of two main points; 1) diverse groups of animals evolve from one or a few common ancestors; 2) the mechanism by which this evolution takes place is natural selection.Evidence that supports the theory of evolution are fossils, embryological studies, anatomical and morphological characteristics (homologous organs, analogous organs, vestigial organs), molecular biology (comparing DNA sequences).which of the following species of fish would likely contain the highest levels of contaminants? mahi-mahi swordfish flounder salmon
Swordfish would likely contain the highest levels of contaminants.
sun-->sagebrush-->jackrabbits-->coyotes
What would happen to this ecosystem if the amount of rain increased? plsss tell me
The amount of sagebrush would increase, which would lead to an increased population of jackrabbits, as sagebrush their food source. As the amount of jackrabbits increase, it gets easier for coyotes to hunt for them which in return, increases their survival rate/population.

A student is investigating the strength of electromagnets she created using batteries, wire, and nails.
She uses two different-sized nails and varies the number of coils of wire around the nail to determine how many paper clips each configuration can lift. She makes a data table of the results.
The student hypothesizes that the number of coils has a cause-and-effect relationship on the strength of the magnetic devices she made. Which would be the best way for the student to test the devices to be sure that her hypothesis is accurate?
Explanation:
You will change two variables to make different electromagnets: the number of wire coils around the nail (10 or 20) and the number of D cell batteries.
What prior species of hominids did homo sapiens encounter in europe approximately 40,000 years ago?.
Answer:
Neanderthals
Explanation:
Homo sapiens encountered neanderthals in europe and had offspring.
The prior species of hominids that Homo sapiens encounter in Europe approximately 40,000 years ago is Neanderthal.
What is species?
Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
While the form of the head and face was not significantly different from that of current humans, there were still quite a few distinctions. Most notably that of the modern human head, which is shorter and has a less prominent facial front. Neanderthal was a former human.
Therefore, the Neanderthals are the ancestors of Homo sapiens, who first encountered them in Europe some 40,000 years ago.

Scientists have several theories about magma hotspots and mantle plumes. They are theories because neither can be observed within the Earth's layers. Scientists say a model of a hotspot/mantle plume location in the Earth is much like a lava lamp. Consider the photo of the lava lamp and complete the analogy. Select which description would not apply
Most Magma Hotspots are situated under the African Plate. Others occur very close to the diverging plate boundaries. Some are also known to be underneath Iceland, the Azores, and the Galapagos Islands.
What is a Magma Hotspot?A magma hot spot refers to an area on the Earth domiciled over a mantle plume where molten magma is hotter several degrees than surrounding magma.
The magma plume causes melting and thinning of the rocky crust and widespread volcanic activity.

Why is cellulose important for explaining how carbon atoms get "locked up" (stored) in a tree as long as it is alive?
O Cellulose is what is produced in photosynthesis.
O Cellulose is used to make new cell walls, when tree cells divide, which become part of the tree.
O Cellulose is made up of CO2 molecules from the atmosphere that stay in the tree.
O Cellulose is what the trees use to make starch, which stores energy for the tree to use later.
Cellulose is a very common organic chemical compound in the plant kingdom and is made up of CO2 molecules from the atmosphere that stay in the tree.
What is cellulose?It is a biopolymer, that is, a long chain of carbohydrates, composed exclusively of glucose molecules (β-glucose) linked together by hydrogen bonds.
It is synthesized by the photosynthesis of plants and whose main function in plant tissues is support, that is, it is part of the cell wall of plant cells.
Therefore, we can conclude that cellulose is a very common organic chemical compound in the plant kingdom and is made up of CO2 molecules from the atmosphere that stay in the tree.

Answer:
C.) 2
Explanation:
Just a side note, I just assigned a random letter to work through this problem. It does not matter what you choose.
The carrier genotypes are Aa while any non carriers are AA, and any affected would be aa.
You would go through each of the pairs and do a pedegree to find out the genotypes of the offspring they produce. For 1 it would be a pedegree for Aa from the mom and AA from the dad. There offspring would be 1/2 Aa and 1/2 AA.
For number 2 it would be Aa for the mom and Aa for the dad. There offspring would be 1/4 AA, 1/2 Aa, and 1/4 aa.
For number 3 the mom would have AA and the dad would be aa. There offspring would be 4/4 Aa
For number 4 the mom would be Aa and the dad would be AA. There offspring would be 1/2 AA and 1/2 Aa.
Group #2 are the only set of parents that would produce a offspring that would be affected by the genetic condition, so the answer is C
