Answer:
Yes. Upper-layer skin cells and the cells in the front surface of the eyes get a significant amount of oxygen directly from the air rather than from the blood. Human bodies have a huge demand for oxygen. As a result, the oxygen that is able to passively diffuse into the body directly from the air is not nearly enough to run the whole body.

what is photosynthesis ?
the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.
Answer:
Photosynthesis is the physical process in which plants make their food with the help of biotic and abiotic components.

1- How could you tell whether a given sequence was DNA or mRNA?
2- Was it easier to decode messages written in DNA or in mRNA sequences?
3- Which cellular enzymes or machines are you imitating when you "transcribe" DNA into mRNA?
4- Which cellular enzymes or machines are you imitating when you "translate" mRNA into a chain of amino acids?
5- What else needs to happen in a eukaryotic cell between the processes of transcription and translation?
6- In step 5, how did different mutations affect the amino acid sequence that was encoded?
7- Explain why some single nucleotide mutations affect an amino acid sequence and some single nucleotide mutations do not.
8- Explain why nucleotide insertions and deletions affect the amino acid sequence so profoundly.
9- Why could your secret message include only 20 of the 26 letters of the alphabet?
10- Did you find that it was difficult to work with only these letters?
Answer:
DNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
The cellular enzyme that carries out transcription is RNA polymerase.
The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.

Biotic and abiotic factors affect population density and dispersion. A) Explain the factors that affect a population's density. B) Describe the types of population dispersion, with examples, and the factors that influence them.
Answer:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources.
Explanation:
Water supply, climate, shape of the land, vegetation, soils and availability of natural resources are the factors that affect population density of an ecosystem. There are three types of population dispersion are uniform dispersion, random dispersion, and clumped dispersion. In uniform dispersion, individuals of a population are more or less evenly distributed for example, allelopathy plants. In random dispersion, individuals are distributed randomly in the ecosystem for example, dandelions plants. Clumped dispersion is when individuals in a population are clustered together for example, oak trees.

The map illustrates the greenhouse gas emissions by country in 2000. What statement correlates the map with the ecological footprint of the country?
A)Only larger countries impact greenhouse gas levels on a global scale.
B) Less developed countries have equivalent greenhouse gas emissions to industrialized nations due to their reliance on burning biomass for fuel.
C) The United States has a smaller population than China, but has a higher per capita greenhouse gas emission, resulting in a larger carbon footprint on a national level.
D) Although the United States and China are roughly the same geographical size, the United States must have a larger population of citizens to result in a higher level of greenhouse gas emissions.
Answer:
C) is correct
Explanation:
The United States has a smaller population than China, but has a higher per capita greenhouse gas emission, resulting in a larger carbon footprint on a national level.
Is it C? Be honest don’t agree cause I think it’s one thing
answer:
c) if, then statement **you chose the correct answer**
explanation:
the hypothesis is an educated guess as to what will happen during your experiment. the hypothesis is often written using the words if and then. for example, "if i don't study, then i will fail the test." and since c) is the only answer choice that matches this description, c is the correct answer

Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.
Thus, Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance.
The homozygous genotypes' two alleles are not expressed over one another in incomplete dominance; instead, an intermediate heterozygote is created.
A significant contributing factor to the variety in the traits or properties of an organism is incomplete dominance.
Thus, Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.

What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?(this is for gizmos lab carbon cycle)
Answer: When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere.
9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.
What is the total amount of carbon added to the atmosphere from soil and the burning of fossil fuels?According to the Intergovernmental Panel on Climate Change, the average annual increase in carbon dioxide concentration from 2000 to 2009 was about 1.9 parts per million (ppm) per year, of which about 55% came from the burning of fossil fuels and industrial processes, and about 45% came from land-use change, primarily deforestation.
Thus, in terms of actual amounts, this translates to roughly 9.4 gigatons (Gt) of carbon per year from fossil fuels and 7.6 Gt of carbon per year from land-use change, for a total of approximately 17 Gt of carbon added to the atmosphere each year.
