Due to the higher concentration of oxygen in the air than your blood, oxygen goes from the lungs into the red blood cells by simple diffusion.
It should be noted that oxygen diffuses from the lungs into the red blood cells. It then binds to hemoglobin. A molecule of hemoglobin can bind with four molecules of oxygen.
Since the red blood cells have cell membranes that are thin, this then enables oxygen to be able to diffuse quickly.
In conclusion, the correct option is simple diffusion.

Which of the following influences the amount of ozone pollution near Earth's surface?
O An area's weather patterns
O Nearby water resources
O Volcanic eruptions
O Plants undergoing photosynthesis
Answers
All the four options can lead to ozone pollution near the earth's surface.
Ozone Pollution- Increased wheezing, coughing, and chest tightness are brought on by ozone pollution, which results from hydrocarbon and nitrogen oxide emissions from cars and other sources mixed with sunshine.
Plants undergoing photosynthesis- Significant producer of VOCs (Volatile Organic Compounds) is woody vegetation. Before they react to generate ozone in the atmosphere, where it can linger for several weeks, NOx and VOCs can be transported over great distances by local weather patterns.Volcanic eruptions- Volcanoes probably generate enough bromine to deplete the ozone layer locally and alter the chemistry of the stratosphere. According to estimates, 1 to 5 percent of ozone damage is thought to be caused by volcanoes, 15 to 20 percent by other natural sources, and a staggering 75 to 85 percent by human activity.Water resources- From farms, factories, and towns, streams and rivers transport pollutants like chemicals, fertilizers, and heavy metals into our bays and estuaries, where they are then transported out to sea. The wind also brings in marine waste, particularly plastic, as does water from storm drains and sewage systems.Weather Patterns- As a result of global warming, there will be an increase in more extreme weather, including heat waves, extreme rainfall events, and other phenomena. Because the chemical reactions that produce ozone in the atmosphere take place more often in hot temperatures, heat waves increase the amount of ground-level ozone pollution.To learn more about ozone pollution- https://brainly.com/question/14154063

A cladogram is a branching diagram that represents the hypothetical relationship (phylogenetic relationship) between different groups of organisms. It is used in phylogenetic analysis to determine the evolutionary relatedness between organisms.
Each branch on a cladogram represents an evolutionary lineage. The names of specific taxa are placed at the end of each branch, while the names of groups to which those taxa belong are placed at the intersection of branches (nodes). By analyzing shared characteristics among different species and their ancestors, scientists can use cladograms to propose and ask questions about their evolutionary relationships.

How is it possible that muscle and fat cells make up 75% of human cells by weight but 84% of cells are red blood cells?
Answers
RBC’s make up about 84% of cells in the body, but they are only 4% of body weight. Whereas, 75% of total weight are fat cells and muscle cells. They’re both large cells but constitute only a minute fraction of the total number of cells.
How many cells is the human body made of?
The exact number of cells is still debatable. But to put it briefly, around 30-40 trillion. The long answer? Not yet determined.
What we do know, is that RBC’s (red blood cells) make up the majority of cells in our bodies. They make up only 4% of total mass, despite constituting 80% of all cells. The reason is that RBC’s measure 8 micrometers in diameter. The size of fat cells, however is around 100 micrometers.
The total number of cells to this date is still not defined, but we have a slight idea of what could be.
Therefore, the reason for RBC’s having 84% of cells and 75% of fat cells is their mass. RBC’s are only 4% of total weight because their measure is only 8 micrometers. Whereas fat cells are around 100 micrometers in diameter.

Answers
Answer:
relaxed packaging of the chromatin and increased transcription.
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and are responsible for condensing it to chromatin.
Typically, acetylation of histone tails leads to relaxed packaging of the chromatin and increased transcription.
Transcription can be defined as a process which typically involves re-writing the informations contained within a Deoxyribonucleic Acid (DNA) into a Ribonucleic Acid (RNA) by enzyme RNA polymerase.

A bacterial culture is growing exponentially. At 7:00 AM, the number of cells was estimated to be 5.5 X 104 cells. At 11:00 AM, the number of cells increased to 8.7 X 107 cells. What is the generation time in minutes of the bacteria? Please assume we are in the log phase of growth for this bacterial population. Please show your work.
Answers
N = N0 x 2^(t/g)
where:
N0 = initial number of cells
N = final number of cells
t = time elapsed
g = generation time
We can use the information given to solve for g.
At 7:00 AM, N0 = 5.5 x 10^4 cells
At 11:00 AM, N = 8.7 x 10^7 cells
The time elapsed is 4 hours, or 240 minutes.
Substituting these values into the formula, we get:
8.7 x 10^7 = 5.5 x 10^4 x 2^(240/g)
Dividing both sides by 5.5 x 10^4, we get:
1582.7 = 2^(240/g)
Taking the logarithm of both sides (base 2), we get:
log2(1582.7) = 240/g
Solving for g, we get:
g = 240 / log2(1582.7)
Using a calculator, we find that g is approximately 29.3 minutes. Therefore, the generation time of the bacteria is approximately 29.3 minutes.

What are recessive alleles?Recessive alleles are alleles that are encoded by recessive genes.
Recessive alleles do not appear phenotypically except when the dominant allele is absent. Hence, recessive alleles only appear in an offspring that is hom0zygous for the given recessive allele.
Hom0zygous means that the two copies of the allele are the same for that trait, either they are hom0zygous dominant or hom0zygous recessive.
Considering the given question:
the allele for long eyelashes is dominant (L) and the allele for short eyelashes is recessive (l) in humans and the allele for free earlobes is dominant (E) and the allele for attached earlobes is recessive (e).
A man homozygous recessive for both traits has children with a woman who is homozygous dominant for long eyelashes and homozygous recessive for earlobes.
Genotype of the man = llee

does the value of acceleration due to gravity vary from planet to planet explain
Answers
Answer: The value of acceleration due to gravity, commonly denoted as "g," is the acceleration experienced by an object due to the force of gravity acting upon it.
The value of g varies from planet to planet because the strength of the gravitational force depends on the mass of the planet and its distance from the object experiencing the force.
Explanation: On Earth, the standard value of g is approximately 9.8 m/s^2. This means that an object weighing 100 grams on Earth would experience a force of approximately 9.8 newtons (N) acting upon it due to gravity.
The value of g varies slightly from planet to planet because the strength of the gravitational force depends on the mass of the planet and its distance from the object experiencing the force.
For example, the value of g on the Moon is about 1.62 m/s^2, which is about 60% of the value on Earth. The value of g on Mars is about 3.71 m/s^2, which is about 30% of the value on Earth.
