The correct answer as to which molecules some examined meteorites contain would be lipids, nucleotides, amino acids, and monosaccharides.
Meteorites are considered to be pieces of rocks or metals that fall into the earth from outer space. These rocks/metals have been extensively studied/analyzed by some researchers, especially those seeking to prove/disprove the Panspermia theory that life originates from other planets.
Several studies conducted found compounds such as lipids, DNA, RNA, and amino acids. There has been no evidence for monosaccharides for a long time until 2019 when an international team discovered sugars such as xylose and arabinose in certain meteorites. No polypeptide has been discovered in meteorites, but its precursor, amino acids, have been discovered.Therefore, the correct answer to the molecules that have been found in some meteorites would be lipids, nucleotides, amino acids, and monosaccharides.

A Congressional Budget Office (CBO) estimate put the bill's cost at $182 million over five years when the bill was first introduced in 2016. The policy of the U.S government includes strong support for research into and preparedness for the effects of space weather. Does the government's policy match its actions? Does it match the seriousness of the situation? What are the consequences?
During the Obama Administration, a significant step was taken by the administration in order to prepare critical technology and infrastructure in order to curtail the risk of the space weather.
Space weather simply means the effects that emissions from the sun, have on the space environment. Space weather can have a negative impact on the infrastructures that are essential to the economy like water supply, electrical power, transportation, health care, etc.Space weather is a concern now due to the fact that the modern technology depends on signals and these are vulnerable and can be affected by space weather. The Executive Order was put in place to help in the reduction of economic loss and saving of lives of the people. The policy of the government matches it actions. In order to support the space weather research, it should be noted that National Aeronautics and Space Administration[NASA] keeps an eye and observes the space environment often by using solar observatories and studying the solar atmosphere, magnetic fields etc. and other bodies that surround the Earth.Read related link on:

Which of the following mechanisms of change in genefrequencies is responsible for the antibiotic resistance of E. coli in this experiment?
A. founder effect
B. natural selection
C. population bottleneck
D. genetic drift
Natural selection is the mechanism responsible for the antibiotic resistance of E. coli.
Natural selection is a mechanism that favors the adaptation of organisms to survive in their environment, thrive and reproduce.
In the context of antibiotic resistance, antimicrobial substances exert selective pressure on microbes that encourages the evolution of resistance.
Those capable of resisting the effects of antibiotics survive and reproduce, while the vulnerable either die or have their growth inhibited.
The excessive and inappropriate use of antibiotics favors selection for antibiotic resistance in bacteria.
E. coli is characterized by having Gram negative bacilli, it represents the greatest risks of zoonotic transfer of resistance.
In general, and when a treatment is short, there is an elimination of sensitive saprophytic strains of E. Coli and an enormous predominance of resistant strains.
Bacteria also acquire antimicrobial resistance through vertical or horizontal transfer of genetic information.
Therefore, we can conclude that resistance to antibiotics in E. coli is due to the process of natural selection since it evolves to resist the action of an antimicrobial agent.

WHAT IS CORRELATION?
Correlation coefficient, denoted by "r", is used in statistics to show the degree of relationship between two linearly related variables. The correlation coefficient (r) can either be positive or negative depending on whether the relationship is inverse or direct. The value of the correlation coefficient is used to depict the strength of the relationship. The closer the correlation is to +1 or -1, the stronger the relationship between the two variables. That is; -1 ≤ r ≤ +1Therefore, the strength of the relationship between two variables increases when correlation approaches +1.00 or -1.00.

Viruses and bacteria can infect human cells. Bacteria are living organisms, while viruses are not. How do you think the treatment for viral and bacterial illnesses differ? How do you think they affect healthy body cells? Explain your response.
Answer:
hope it helps
Explanation:
1) antibiotic drugs can kill bacteria however, they are not effective against viruses
2) some bacteria's help to digest foods and speed up enzyme reactions. Some bacteria cells destroy disease causing cells
The treatment for viral and bacterial illnesses differs primarily due to the fundamental differences in their nature and characteristics. Bacteria are living organisms that can be targeted by antibiotics, whereas antiviral medications are used to treat viral infections.
Both bacteria and viruses can affect healthy body cells, with bacteria directly invading cells and causing damage, while viruses rely on host cells for replication and can induce damage during the process.
Bacteria and viruses can both cause damage to host cells. Bacteria can directly invade and damage cells through mechanisms such as releasing toxins or inducing inflammation.
Viruses require host cells to reproduce. They invade host cells, hijack cellular machinery to replicate themselves, and subsequently cause damage to the infected cells during the process.

A person lives on the Tropic of Capricorn. What is the altitude of Polaris?
O 23 1/2"
O 90°
O 66° 33"
O 15°
O 30°
O 45°
The correct answer as to what the altitude of Polaris would be for a person that lives on the Tropic of Capricon is 23° 1/2".
Polaris is a star and the altitude of any star is its height above the horizonThe Polaris is otherwise known as the North star as an indication that it is directly located overhead the north pole. Thus, it may not be visible once one moves South of the equator. The tropic of Capricon is located approximately 23° 1/2" South of the equator. In other words, the latitude of the Tropic of cancer is approximately 23° 1/2".Hence, the altitude of the Polaris at an altitude of 23° 1/2" will also be 23° 1/2", although it will most likely remain invisible.A person that lives on the Tropic of Capricon is approximately on latitude 23° 1/2". Since the altitude of a star is its height above the horizon, the altitude of Polaris from the Tropic of Capricon would, therefore, be 23° 1/2"

Why do some scientists believe that RNA, rather than DNA, was the first genetic material?
RNA can replicate more accurately than DNA.
RNA contains uracil in place of thymine.
All of the protocells on early Earth contained RNA.
RNA has both information storage and catalytic properties.
The correct answer as to why some scientists believe that RNA, rather than DNA, was the first genetic material would be that RNA has both information storage and catalytic properties.
Other options are cannot be correct because:
RNA cannot replicate itself unless it is in a living host.RNA containing Uracil instead of Thymine has no effect on being the first genetic material or otherwise.There is no clear evidence to show that all of the protocells on early Earth contained RNAThe fact that RNA has the capacity to store information as well as catalyze important biological processes made it a plausible candidate as the first genetic material.

Inhumane factory farming methods have a huge tendency to contribute to environmental degradation. Explain the connection between inhumane factory farming methods and environmental degradation and further motivate why a study on such factors is important.
Inhumane or uncontrolled factory farming methods posses a high risk to the surrounding environment. This is because of the farming activities that can lead to degradation (pollution) of the environment.
Factory farming is an industrialized type of farming that involves both the growing of crops as well as the rearing of livestock in a confined area in order to maximize production at minimal cost.
There are some practices carried out while using this farming method which when poorly managed can lead to the degradation of the environment. They include:
Bush burning: Repeated cycles of bush burning in a given area can damage the soil, making it become powdery and dry with poor nutrient content. Tillage: An over tilled soil will become dry and powdery. Its topsoil can easily be blown away resulting to land erosion.Fertilizers: This must be added to the soil in correct amount, according to the mineral requirement pf the soil that is to be planted on it. This is done to avoid excess fertilizers washing into nearby water bodies.pesticides: These are used to control agricultural pests. Farmers are advised to use them with great care and only when essential. This is because when the plant products are consumed, some of the chemicals can accumulate in the body leading to harmful effects.Learn more here:

Describe the digestion of fats.
You should include reference to the following in your answer.
- Named regions of the alimentary canal and associated organs.
- Named chemicals, including the end producys of fat digestion.
Answer:
The majority of fat digestion happens once it reaches the small intestine. This is also where the majority of nutrients are absorbed. Your pancreas produces enzymes that break down fats, carbohydrates, and proteins. Your liver produces bile that helps you digest fats and certain vitamins.
Answer:
Triglycerides are large molecules, and unlike carbohydrates and proteins, they're not water-soluble. The digestive process has to break those large droplets of fat into smaller droplets and then enzymatically digest lipid molecules using enzymes called lipases. Digestion of fats mainly take place from fat enzymes produced in liver.
