Increase in the metabolic activities of the fish necessitated the increase in the consumption of oxygen hence the straight line graph.
What is an experiment?We know that when we carry out an experiment, the aim of the experiment is so that we can be able to deduce the nature of the relationship that is seen to exist between two variables. The variables are the independent and the dependent variables. The dependent variable is directly affected by the independent variable as it changes.
We are also told that what we have here is a straight line graph. This implies that the amount of oxygen that the fish was using was increasing as the age of the fish was increasing. This is what has accounted for the straight line graph.
Now we can see that the reason why we have a straight line graph is that the metabolic activities of the fish was increasing as the age of the fish was increasing thus it had to take in more of the oxygen.

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.

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.

The outside surface of epidermis is covered in a waxy coat called cuticle. This cover prevents the loss of water.
The circle below represents sells the arrow shows the movement of materials State whether each diagram represents active or passive transport
Passive transport carries molecules from the more concentrated side to the less concentrated one, while active transport carries molecules against their electrochemical gradient, needing the energy to do it.
Note: Since the image is not attached and I could not find it, I will define active and passive transport and attach an image with cells, molecules, and arrows indicating molecule motion for each transport case.
What are active and passive transport?Active and passive transport are two ways in which substances can move through the plasmatic membranes.
Passive transport occurs in favor of an electrochemical gradient and does not need energy to move because molecules move from the more concentrated side to the less concentrated one.
Simple diffusion and facilitated diffusion are two types of passive transport.
On the contrary, active transport moves molecules against their electrochemical gradient. This means that molecules move from the concentrated side to the more concentrated one. This process needs the energy to occur.
In the attached image you will find two scenarios. One of them is passive transport and the other one is active trasport. You should notice the differences in substances concentrations at each side of the membrane, and the arrow direction.

The Atlantic puffin feeds on several species of Atlantic fish. A population of puffins living on Matinucus Rock was found to feed on the types of fish shown in the graph below. The beaks of this group of puffin are shaped to grasp Species A particularly well. Predict what would happen to the puffins’ beaks if another predator enters the area that is better at preying on Species A. Explain your reasoning based on what you know regarding genetic adaptations.
The number of Atlantic puffins that have adapted to species A will decrease as competition for species A increases. After several generations, the puffins that eat species B and C will be formed.
What is adaptation?
Adaptation is the process of changing in response to a changing environment. An example is seen in puffins. The puffin that eats species A has a different beak. When another predator enters who preys upon species A, then competition will increase. As a result, species A's consumption of puffin will decrease.
Those puffins that eat species B and C will survive. They will reproduce and produce more offspring. The number of puffins with beaks in Species B and C will increase over time.
Hence, after many generations, puffins of species B and C will increase.

Chlorophyll in the chloroplast reflects green color on the spectrum of

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.
