Answer:
Presence of inorganic molecules
Explanation:
Earth's primitive atmosphere contained a mix of different inorganic compounds (gases) including, among others, water vapor (H2O), carbon dioxide (CO2), ammonia (NH3), methane (CH4), etc. It has been proposed that these inorganic molecules would generate the conditions needed to form a "primordial soup" of organic molecules (i.e., RNA nucleotides, amino acids, etc). Subsequently, this soup would accumulate in water bodies of the primitive Earth due to endogenous abiotic syntheses and the delivery caused by comet/meteorite collisions.

7. Which molecule is light energy temporarily stored in before being used to make glucose?
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light

Which of the following is an example of specific immunity?
Answer:
Immunity to Small Pox
Explanation:
Over the years, Europeans had built up an immunity to smallpox because many had contracted the disease and still survived. As the population grew children were born with some immunity to the disease. When the Europeans arrived in the Americas, and smallpox spread around the native peoples, the Europeans did not contract the disease because they were immune. However, since the natives were not immune, they slowly died of due just to the disease as well as some parts of the war between the europeans.

A sample of human DNA is made up of approximately 30% adenine. The quantity of cytosine found in human DNA will be 20%. The correct option is B.
What is DNA base pairing?DNA base pairing is the pairing or joining of DNA bases to each other with hydrogen bonds. There are four types of bases present in DNA. They are adenine, thymine, cytosine, and guanine.
Adenine pairs with thymine with double hydrogen bonds and cytosine joined with guanine with triple bonds of hydrogen. The pairing between these base pairs is alternated in the sequence of DNA.
According to the base pairing rule. There will be 100% of these bases present together. So if there is 30% adenine, there will be 30% thymine. The total becomes 60%. Now remain is 40%. So there will be 20 % cytosine and 20% guanine.
Thus, the correct option is B 20%.

A. The sun heats the air at the equator, followed by hot air rising and moisture condensing
B. Air moves towards the poles as it cools
C. The dry air moves back to the equator, picking up a lot of moisture on the way
D. The air sinks around 30° latitude and is very dry.
Answer:
B. Air moves towards the poles as it cools
Explanation:
The image represent convection cell or Hadley cell is a natural phenomenon in the atmosphere that occur due to difference in the density within a body of liquid or gas. These differences in density causes rise and fall in currents.
The process in step A refers to when hot air moves up and in the step B, the hot air encounters a cold surface, it direct exchange the heat with cold surface and the air cools down and move towards the poles.
Hence, the correct answer is "B. Air moves towards the poles as it cools".

Are the Earth's seasons caused by the differences in the distance
from the Sun throughout the year or the tilt of the Earth's axis?
Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.

Give two ways in which saliva aids digestion.
Explanation:
Saliva contains special enzymes that help digest the starches in your food. An enzyme called amylase breaks down starches (complex carbohydrates) into sugars, which your body can more easily absorb. Saliva also contains an enzyme called lingual lipase, which breaks down fats.

In about 100 words, explain how the use of flashback adds meaning to “Rules of the Game.” Be sure to use details from the story to support your answer.
Answer:
“Every time people come out from foreign country, must know rules. Throughout the story, Waverly describes past incidents when cultural differences caused her and her mother to view events differently. Waverly sees events differently because of her American upbringing. Her mother sees events differently because of her Chinese upbringing. She shows this struggle when she describes her mother’s reaction to the game manual for her brother’s new chess set: “This American rules,” she concluded at last.The The use of flashback in "Rules of the Game" provides insight into the complicated relationship between Waverly and her mother. You not know, judge say, Too bad, go back. Better you take it, find out why yourself.” She tossed her head back with a satisfied smile. Waverly notes that her mother has had difficulty adjusting to American culture. They say, Don’t know why, you find out yourself. They not telling you why so you can use their way go forward.

Why is the line graph a curve instead of a straight line?
Answer:If it's important to display the exact values, then the straight lines do a much better job. But often you'll find that what matters is the trend and the precise measurements are secondary. ... A straight line suggests that the value between the two measurements increased linearly, while a curved line suggests otherwise.

Identify the correct transcriptions between DNA to mRNA
CTGACTGACC to GACUGACUGG
OGGATCTCTCA to CCTAGAGAGT
TACTACGGAT to UTGUTGCCTU
AGCTCCGATC to UCGAGGCUAG
OGCTAATCGAT to CGAUUAGCUA
CATCTATGAG to GTUGUTUCTC
No
Answer:
CTGACTGACC to GACUGACUGG
AGCTCCGATC to UCGAGGCUAG
GCTAATCGAT to CGAUUAGCUA
Explanation:
Transcription is the process whereby a DNA template is used to form a mRNA molecule in the nucleus following the complementary base pairing rule. The complementary base pairing rule as postulated by Chargaff states that an Adenine base will always pair with Thymine (Uracil in RNA) while Guanine base will always pair with Cytosine i.e A-U, G-C.
N.B: Thymine in the DNA will yield Adenine in the mRNA while Adenine in the DNA will yield Uracil in the mRNA.
Hence, according to this question, the following DNA templates will be transcribed as follows:
1. CTGACTGACC to GACUGACUGG
2. AGCTCCGATC to UCGAGGCUAG
3. GCTAATCGAT to CGAUUAGCUA

1. How would you describe the biosphere?
2. What are some ways we, as humans, affect the biosphere?
Answer:
1. The Biosphere is a life-supporting stratum of Earth's surface, extending from a few Km into the atmosphere all the way to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients
2. Humans burning fossil fuels and growing animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. Humans have caused threats to non-renewable resources, CO2 production& global warming, as well as over-competition for food between native and introduced species.
PLZ HELP IM TAKING MY EXAM!! which of the following best explains the impact of mrna being double stranded before translation
Answer:
Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.
Explanation:
The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.
Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.
If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.
