The air that is breathed in contains oxygen in a concentration of 20% while the air exhaled still contains oxygen in a concentration of 16%. This implies 4% oxygen has been absorbed by the blood cells per breath.
Even though 16% of the oxygen in the air is exhaled, hemoglobin is 100% saturated with oxygen.We only exhale 16% of the oxygen we breathe in because some parts of our lungs are not actively engaged in gas exchange.The conducting parts of the airways that do not take part in the exchange of oxygen and carbon dioxide include the nose, mouth, and windpipe, for instance. They only move air from the atmosphere to the interior of the lungs. The distal-most air sacs, known as the alveoli, where gas exchange takes place, are the functioning parts of the lungs.Therefore, the air from the nose, mouth, and windpipe still contains all of the oxygen when we exhale, and this accounts for the 16% of oxygen that is lost during breathing.

Distinguish between descriptive, correlational, and experimental research
The goal of descriptive research is to offer a snapshot of the existing situation. Finding relationships between variables is the goal of correlational research. Experimental studies aim to evaluate cause and effect.
What is the research about?A population's or phenomenon's characteristics are described through descriptive research. It does not provide an explanation for when, how, or why the features developed. Instead, it answers the "what" query.
With a correlational research design, correlations between two variables—or more—are examined without any of the variables being under the researcher's direct control or manipulation. It is a form of quantitative study that is not experimental.
A study that carefully follows a scientific research strategy is called experimental research. It consists of a hypothesis, a controllable variable, and variables that can be measured, calculated, and compared. Most crucially, controlled environments are used to conduct experimental research.

Describe the following spheres of the Earth.
1. Geosphere
2. Biosphere
3. Atmosphere
4. Hydrosphere
Explanation:
1. Geosphere
Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the portion of the earth that includes rocks and minerals. It starts at the ground and extends all the way down to Earth’s core.
We rely on the geosphere to provide natural resources and a place to grow food. Volcanos, mountain ranges, and deserts are all part of the geosphere.
2. Biosphere
Bio means “life.” The biosphere is made up of all the living things on Earth and it includes fish, birds, plants, and even people.
The living portion of the Earth interacts with all the other spheres. Living things need water (hydrosphere), chemicals from the atmosphere, and nutrients gained by eating things in the biosphere.
3. Atmosphere
Atmos means “air.” The atmosphere includes all the gases surrounding the Earth. We often call the atmosphere “air.” All planets have an atmosphere, but Earth is the only planet with the correct combination of gases to support life.
The atmosphere consists of five layers and is responsible for Earth’s weather. Even though it seems like air is made of nothing, it consists of particles too small to be seen. All these particles have weight that push down on Earth. The weight of air above us is called air pressure.
4. Hydrosphere
Hydro means “water.“ The hydrosphere includes the oceans, rivers, lakes, groundwater, and water frozen in glaciers. 97% of water on Earth is found in the oceans. Water is one of the most important substances needed for life and makes up about 90% of living things. Without water, life would not be possible.
how do immunizations work with viruses?
Answer:
immunisations can help protect against certain diseases by imitating an infection. This type of imitation infection, helps teach the immune system how to fight off a future infection. Sometimes, after getting a vaccine, the imitation infection can cause minor symptoms, such as fever. Such minor symptoms are normal and should be expected as the body builds immunity.
Once the vaccinated body is left with a supply of T-lymphocytes and B-lymphocytes that will remember how to fight that disease. However, it typically takes a few weeks for the body to produce T-lymphocytes and B-lymphocytes after vaccination. Therefore, it is possible that a person infected with a disease just before or just after vaccination could develop symptoms and get that disease, because the vaccine has not had enough time to provide protection. While vaccines are the safest way to protect a person from a disease, no vaccine is perfect. It is possible to get a disease even when vaccinated, but the person is less likely to become seriously ill.

Another student thinks a constant should be the speed that the skateboard travels. Is this correct? Explain.
A student thinking that a constant should be the speed that the skateboard travels is not correct.
What is Speed?This is referred to as the rate of change of position with time and the unit is meter per second (m/s).
Speed = distance/time
For a body to have a constant speed, then it means that the sum of all the external forces acting on it is zero. This isn't possible because the numerous forces such as friction, drag etc won't always equal zero which therefore means the student's reasoning is false and not correct and is the most appropriate choice.

Explain why some areas that are surrounded by land (such as the Red Sea) experience a lower pH value overall than the open ocean in genera
Due to the dissolving of minerals carrying hydrogen ions into the water body, some places that are surrounded by land generally have a lower pH than the open ocean.
Why do some places with a land border have a lower pH value?
The hydrogen ion concentration in a medium is determined by that medium's pH.While a high pH indicates a low hydrogen ion concentration, a low pH indicates a high hydrogen ion concentration.Due to the existence of minerals with a high concentration of hydrogen ions, areas that are surrounded by land have low pH levels.The breakdown of minerals carrying hydrogen ions into the water body causes some locations that are surrounded by land to have a lower pH value generally than the open ocean in general.

Explain how the sodium/potassium exchange pump in the axon of neurons
maintains polarity. (2 marks)
Explain why polarity in an axon is necessary.
The sodium-potassium pump maintains cell polarity by moving ions in and out against their concentration gradient, thus maintaining a negative electrical voltage within the cell.
What is the sodium/potassium exchange pump?The sodium/potassium exchange pump is necessary for the exchange of potassium ions for sodium ions, this will be found in the cell membrane and will help maintain the functioning of the cell and the body in general. This process of exchanging sodium for potassium is going to be done against its concentration gradient, since this is impossible by cell media alone, since it is an unfavorable process for the cell, it is going to be necessary to spend energy in the form of ATP, hydrolyzing it, releasing the energy found in its bonds.
Therefore, we can confirm that the sodium-potassium pump maintains cell polarity by moving ions in and out against their concentration gradient, thus maintaining a negative electrical voltage within the cell.

Attached earlobes are a recessive trait in humans. In the tree below, people
with attached earlobes are shaded in. Which best describes the person
labeled X in the tree
A male with one recessive allele is the correct answer.
What do you mean by recessive allele:
Earlobes of this kind are tiny and fastened firmly to the side of the head. The lack of the dominant allele in the chromosomes is what causes this type of lobe to form structurally. An connected earlobe is expressed by the recessive allele.
The children from this generation are the result of a cross between homozygous recessive (one parent) and heterozygous (two parents) parents. All of the filial 1 (one) generation's kids will therefore carry a recessive allele. The attached earlobe trait won't be present in people with the same dominant allele, though.
Having an attached earlobe a dominating human characteristic?Some people's ear lobes are free, whereas others have them linked to the side of the head. This is caused by a gene that is recessive in people with attached earlobes and dominant in people with detached earlobes. Therefore, in humans, attached ear lobes are recessive.

At each new wavelength, the spectrophotometer was "blanked" to ensure that measurements of the absorption of water and cuvette did not conflict with those of the dye.
Since the water and cuvette likewise ingest light, the spectrophotometer won't gauge their retention, it is essential to "clear" the gadget prior to estimating an example's retention at each new wavelength.
Since the stretch chosen was great for estimating the arrangement due to having high absorbance esteem, the ingestion of indigotin arrangement was estimated at similar spans.
