Describe the path of a nitrogen atom through four parts of the nitrogen cycle. Be sure to explain the processes involved in the transfers. Note when a form of nitrogen is available to plants.
Answer:
Explanation:
Nitrogen cycle consists of four main steps namely:
Nitrogen Fixation.
Ammonification/ Decay.
Nitrification.
De-nitrification.
A strand of DNA was unwound and analyzed. If the nitrogen bases of the strand were A-T-C-G-G-A, what was the sequence of nitrogen bases on the other strand? Explain.
Answer:
U-A-G-C-C-U because the other strand is always the opposite so if it's G then it will be C and that goes backwards too and for T it's A but u can't put T on the other strand so u substitute it for U

Write characterize progression of infectious disease.
Answer:
* Infectious disease management depends on precise portrayal of disease progression so transmission can be forestalled. Gradually progressing infectious diseases can be hard to characterize because of a latency period between the time an individual is infected and when they show clinical signs of disease.
* Defining directions through sickness states from infection to clinical illness can assist researchers with creating control programs dependent on focusing on individual infection state, possibly decreasing both progression and creating misfortunes because of the illness.
Explanation:
Gradually progressing infectious diseases are hard to characterize in light of the fact that they are frequently connected with an inactivity period between the time an individual is infected and when they give clinical indications or side effects of illness.
To successfully control infectious diseases, it is paramount to see how the disease progresses.
Why might farmers and herders have selectively bred their animals and plants?
Answer:
Farmers and herders can derive a surplus of animals and plants with desireable traits. (ex: larger crops, bigger animals, sweeter fruits etc.)
Explanation:
By selectively breeding animals (breeding those with desirable traits), farmers increased the size and productivity of their livestock. Same thing goes for plants. Farmers can selectively breed them so they can become more favorable for their consumers.

Name three fluids that are essential to life. Cite evidence from this section to justify your answer.
Answer:
water:to stay alive
semen:to reproduce
sweat:without we would get heat strokes easier
Answer:
Blood, Saliva, Bile
Explanation:
blood, which functions to transport oxygen to cells, carry metabolic waste products such as carbon dioxide away from cells and transport infection-fighting white blood cells, glucose, hormones and other essential substances throughout the body. Blood also contains cell fragments called platelets and clotting factors that help to seal leaks that may develop in blood vessels.
Saliva is secreted by salivary glands in and around the mouth saliva contains antibacterial enzymes and antibodies, as well as mucus itself. Saliva helps to moisten food, which is important to lubricate chewing and swallowing. It also enhances taste, because if the chemicals in food were not in a liquid medium, they could not be detected by taste receptors.
Bile is a brown to dark green fluid that is produced by the liver, stored in the gallbladder (a synonym for bile is gall), and released into the intestines when we eat. It is partly responsible for the color of vomitus and stool. Its most important ingredient is bile salts, which function like soap to break down dietary fats, enabling them and fat-soluble vitamins such as A, D and E to be absorbed. They also help to prevent the cholesterol-containing bile in the gallbladder from forming gallstones.
what cell components are responsible for detoxifying the cell
RER
SER
ATP
DAF
(Anatomy and physiology)
Answer:
SER
Explanation:
Smooth Endoplasmic Reticulum
These are fat-based molecules that are important in energy storage, membrane structure, and communication (steroids can act as hormones). The smooth endoplasmic reticulum is also responsible for detoxifying the cell.
A type O woman marries a man with type B blood, given that both of their mothers were type O, predict their possible offspring.
Answer:
For a woman with type O blood and a man with type B blood, whose mother was of type O blood, the possible offspring will consist of B and O children.
Explanation:
Blood type is an inherited trait and is determined by the presence or absence of antigens A and B on the surface of the erythrocyte:
Blood type A contains the antigen A and its genotype can be A|A or A|O. Blood type B contains the antigen B, whose genotype may be B|B or B|O. Blood type AB contains both antigens and a single genotype expression A|B. Blood type O lacks surface antigens, with a unique O|O genotype.In the above case, the woman has an O blood type, whose genotype is O|O. The male must be heterozygous, since his mother was of blood type O, so his genotype is B|O.
♂ B|O ♀ O|OTo know the possible descendants of this couple, the crossing of the wolf alleles must be done:
Alleles B O
O B|O O|O
O B|O O|O
From where the probabilities of the offspring are obtained:
Individuals with blood type B and genotype B|O 50% Individuals with blood type O and genotype O|O 50%Therefore, from this crossing only descendants of individuals with blood type B and O can be obtained.

Which two characteristics are shared by all thunderstorms, tornados, and huricanes?
O clouds and wind
O eyes and clouds
O warm, dry air and wind
O large waves and warm, dry air
The two characteristics that are shared by all thunderstorms, tornadoes, and hurricanes are: clouds and wind. The correct option is A.
What are the characteristics of thunderstorms, tornados, and hurricanes?Thunderstorms, tornadoes, and hurricanes are all types of severe weather conditions. They are called severe weather conditions because they can cause a lot of damage to property and people's lives. They are all characterized by strong winds and clouds.
Thunderstorms are storms that have thunder and lightning. They are caused by warm air that rises and cools, creating thunderstorm clouds. They are usually accompanied by heavy rain, gusty winds, and lightning.
Tornadoes, on the other hand, are funnel-shaped clouds that touch the ground. They are usually created by thunderstorms. They are characterized by strong, rotating winds that can cause a lot of damage to structures and vegetation.
Hurricanes are large, tropical cyclones that have low-pressure centers. They are usually formed over warm ocean waters and are accompanied by strong winds, heavy rain, and flooding. They can cause a lot of damage to coastal regions and people's lives.
Therefore, the correct option is A.

Why is it important to know the difference between science and pseudoscience? to look intelligent to make informed decisions to score well on tests to tell believable stories
Answer:
The difference between science and pseudoscience is that science organizes knowledge in testable explanations and predictions about the universe while a pseudoscience is a claim or a belief which is carried out as scientific but has no valid.
Explanation:
It is important to know the difference between science and pseudoscience because it helps in telling believable stories to people who do not have this sense of understanding and still have myths in their mindsets. Thus, the correct option is D.

A scientist wants to make a geologic column of rock layers from different parts of a state. Which claim explains how the scientist will do this?
A. The scientist will organize the layers by comparing the fossils and types of rocks.
B. The scientist will measure the exact ages of the rocks found in each part of the state.
C. The scientists will look at the surface features in each area to organize the layers.
D.The scientist will select one area in the state and use only those layers to construct the geologic column.
Answer:
A. The scientist will organize the layers by comparing the fossils and types of rocks.
Explanation:
A geologic column can be defined as a collection of rock layers that are typically grouped based on their relative ages in a descending order i.e from oldest to the youngest.
Generally, the layers of the rock that are found in various parts of the world are known to be different because they all comprises of distinct Earth's geological history.
In this scenario, a scientist wants to make a geologic column of rock layers from different parts of a state. Thus, the claim which best explains how the scientist will do this is that, the scientist will organize the layers by comparing the fossils and types of rocks.
Hence, the scientist will collect or gather the fossils obtained from various rocks located in different parts of the state and make a comparison.
