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?
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.

What advantages does a coelom provide the earthworm and the salamander?
Explanation:
The coelom refers to the body cavity derived from mesoderm germ layer and mainly found in multicellular animals and is positioned inside the body to surround and contain the digestive tract and other organs.
There are many advantages that coelom provides to the earthworm and the salamander. The digestive system of earthworms and salamanders is more complex, here coelomic fluid helps their body processes and assists as a hydrostatic skeleton.
The coelom's main advantage is its flexibility. The internal organs for example the heart, liver, lungs, and intestines develop, and they help to push into the coelom. The fluid of the coelom diminishes the organs for protecting the organs and also enables them to turn, bend, shift and move. In this way, coelom helps the animals internally to finish and run the system inside in the correct way. Coelom helps the earthworms and salamanders in building the correct system and protecting their organs to maintain and enable them to function properly.

Chlorophyll in the chloroplast reflects green color on the spectrum of
visible light.
What is chlorophyll?
The ability to produce their own nourishment exists in green plants. They achieve this through a process known as photosynthesis, which makes use of the green pigment chlorophyll. A molecule with a specific color known as a pigment can absorb light at various wavelengths depending on the color. Although there are many various kinds of pigments in nature, chlorophyll is special in that it allows plants to absorb the energy they require to develop tissues.The little structures called chloroplasts found in a plant's cells are where chlorophyll is found. This is the location of photosynthesis.Each pigment has a distinctive absorption spectrum that illustrates how it absorbs or reflects various light wavelengths. Chlorophyll and other pigments used in photosynthesis absorb wavelengths, creating electrons that power photosynthesis. All visible light wavelengths, with the exception of green, are absorbed by chlorophyll, the green pigment found in all photosynthetic cells. Because of this, plants seem green to us.
Hence, Chlorophyll in the chloroplast reflects green color on the spectrum of visible light.

(80-100 words) What is sickle cell disease? Describe its effects at a protein, cellular and organismal level.
Sickle cell disease (SCD) is a genetic disorder caused by a mutation in the gene that codes for hemoglobin, a protein responsible for carrying oxygen in red blood cells.
The mutation results in the production of an abnormal form of hemoglobin known as hemoglobin S (HbS). Sickle cell disease is inherited in an autosomal recessive manner, meaning that an individual must inherit two copies of the mutated gene (one from each parent) to develop the disease.
Effects at a Protein Level:
Hemoglobin normally has a rounded shape, allowing red blood cells to flow smoothly through blood vessels. However, in sickle cell disease, the abnormal hemoglobin S causes red blood cells to become stiff and take on a crescent or sickle shape under certain conditions, particularly when oxygen levels are low.
Effects at a Cellular Level:
The sickle-shaped red blood cells are prone to clump together, leading to the formation of blood clots. These clots can block blood vessels, causing a reduction in blood flow to various organs and tissues.

20 million years ago two species share a common ancestor, if the molecules found in these two species differ by a total of eight mutations.
Neutral mutations play an major role in the phenomenon of evolution because they generally take place at a consistent rate over time.
Every time when a genome is passed from one generation to another , a small error is responsible for changing the base sequences. So the mutation rate in the genome copy is calculated by both the rate of error per copy and the number of copies made per unit time. Both of these factors may be impacted by species biology.

Currently, new regulations control the use of pesticides and chemical fertilizers to reduce what?
Pesticides and fertilizers create water and air contamination and significant health consequences. Chemicals are regulated to reduce water contamination.
What are pesticides?Insecticides, fungicides, and nematicides are all examples of pesticides. It is essential to exercise population control over the unwanted organisms and insects that cause severe damage to the crops. On the other hand, pesticides can never be used in excess, as this would have a negative impact on living things.
Fertilizers are added to the soil in order to improve its fertility and thus the development of plants. In addition, they contain hazardous substances.
Both insecticides and fertilizers are known to include compounds that are potentially harmful. These chemicals almost certainly will lead to the contamination of water and air, in addition to causing health problems for the organisms in the surrounding area.
Contamination of water is a critical problem that has been on everyone's minds for a considerable amount of time. It is possible to lessen the amount of water contamination by lowering the amount of pesticides and fertilizers that are used.
