Explanation:

osmosis

refers to the movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules through a cells partially permeable membrane

Importance

- it stabilizes the internal environment of the organism by balancing the level of water and intracellular fluids

General category: Biology.

Sub-category: Cellular membranes

Topic: Diffusion

Introduction:

Diffusion is the random movement of molecules in a given medium toward a state of equilibrium. Then, diffusion is the net movement from regions of greater concentration to regions of lesser concentration.

First of all, remember that if a cell membrane divides a solution into separate compartments, the movement of the different solutes can be affected by the properties of the membrane. The passage of substances depends on whether the membrane is permeable or semi-permeable to different solutes.

Now, the concept of osmosis is based on the idea of diffusion. Osmosis is the diffusion of water across membranes. This means that water will diffuse from a region of its higher concentration (lower concentration of solutes) to a region of its lower concentration (higher concentration of solutes).

Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function. Remember that osmotic equilibrium is the ratio of intracellular fluid to the extracellular fluid. For example, osmotic balance is of vital importance in the functioning of the nephron.

We can conclude that the correct answer is:

Osmosis:

Osmosis is the diffusion of water across membranes where the water will diffuse from a region of its higher concentration to a region of its lower concentration.

Biological importance of osmosis:

Osmosis is vital to maintain the osmotic equilibrium necessary for the cell to function.

Dolphin meat is more likely contaminated and contains higher levels of mercury than other species due to its position in the food chain and the process of biomagnification.

Biomagnification is the process by which the concentration of certain substances, such as pollutants or toxins, increases in organisms as they move up the food chain. Dolphins are apex predators, meaning they feed on other marine animals, many of which have already accumulated mercury in their bodies. As dolphins consume these contaminated animals, the concentration of mercury in their tissues increases. This can lead to bioaccumulation, which is the buildup of toxins in an organism over time and can result in negative health effects.

Blood pressure is lower on the side of the heart because the blood does not need to be pumped as far in pulmonary circulation compared to the systemic circulation.The pressure in the pulmonary artery is lower than the systemic artery because the distance that the pulmonary artery has to pump blood to is much shorter than the distance that the systemic artery has to pump blood to.

Due to the lesser distance to travel, the pulmonary artery will require less pressure to carry blood to the lungs for oxygenation than the systemic artery, which will need to supply oxygen and nutrients to all parts of the body. As a result, the blood pressure on the side of the heart for the pulmonary circulation will be lower than for the systemic circulation.

The primary source of energy in most ecosystems is the sun. Autotrophs, such as plants, use light energy from the sun to produce glucose through the process of photosynthesis.

Correct option is B.

The glucose is then used as a key source of energy for other organisms. Heterotrophs, or consumers, cannot produce their own food, instead they must obtain energy by consuming organic substances, such as glucose produced by autotrophs. This glucose is eventually oxidized by the consumer, releasing energy for use in metabolic activities.

In this way, the sun is the primary source of energy in most ecosystems because it provides light energy that autotrophs use to produce glucose, which is then used as an energy source by other organisms in the ecosystem. Overall, the sun is the main source of energy for living organisms, providing energy to both producers and consumers.

Experiment

In this experiment, as the question the investigators are trying to answer is what component is the limiting one, it is necessary to test every one of them, independently. Therefore, the best option is to change the concentration of one of them and leave the rest unchanged. To accomplish this, would be necessary three different tanks, one for phosphorus, one for iron, and one for nitrogen (option A).

To determine which nutrient is limiting algal growth, the company can add phosphorus to one tank, nitrogen to another, and iron to a third, and see which treatment increases algal growth. Therefore, option A is correct.

By adding each nutrient separately to different tanks and observing the effects on algal growth, the company can identify which nutrient is limiting. If the addition of phosphorus to one tank leads to increased algal growth, it suggests that phosphorus was the limiting nutrient.

Similarly, if the addition of nitrogen or iron to their respective tanks results in increased algal growth, it indicates that nitrogen or iron, respectively, was the limiting nutrient. Thus, option A is correct.

The main reason for the rejection of a transplanted tissue is the body’s immune response. When foreign tissue is transplanted, our body's immune system identifies it as an intruder and tries to reject it.

This is termed as graft rejection. Antibodies are created by the body's immune system to combat the foreign tissue.

The transplanted tissue is attacked by these antibodies, which causes rejection. This results in the transplanted tissue losing its ability to function properly, which causes the transplant to fail.

The age gap between the donor and recipient, immunosuppressant medications, and the existence of any underlying medical disorders are additional factors that can cause tissue rejection.

The body occasionally may develop excessive levels of antibodies, which can further raise the likelihood of rejection.

Answer:

Explanation:

It is impossible to transport O2 from the atmosphere to exercising muscle cells using the process of diffusion in humans because of the following reasons. Firstly, the atmospheric pressure of O2 is insufficient to provide an adequate amount of oxygen for the amount of work done by exercising muscles. Secondly, the concentration gradient of oxygen decreases as oxygen moves through the circulatory system.

The diffusion of oxygen from the atmosphere to the exercising muscle cells is limited because of the insufficient supply of oxygen by the atmosphere, which is inadequate to meet the demand of the exercising muscles. The concentration gradient of oxygen decreases as oxygen moves through the circulatory system, as it is consumed by the cells. As the concentration gradient of oxygen decreases, the rate of oxygen diffusion also decreases, leading to a reduced supply of oxygen to the exercising muscles.

To overcome the limitations of diffusion, the human body uses the cardiovascular and respiratory systems. The respiratory system allows the lungs to take in oxygen and exhale carbon dioxide, while the cardiovascular system circulates oxygen-rich blood throughout the body, supplying the muscles with oxygen.

During exercise, the respiratory and cardiovascular systems work together to ensure that the body receives enough oxygen to sustain the increased demand of the exercising muscles. The lungs increase the rate of ventilation, and the heart increases the rate of blood flow to the muscles. Together, the respiratory and cardiovascular systems increase the supply of oxygen to the exercising muscles, ensuring that they can continue to function efficiently.

             - moving the decimal to the right means you multiply

2. Use your new number, 5.4 and make a new equation

3. Your new equation is, 5.4 times 10 to the 3 power

The number 0.0054 written in scientific notation is \(5.4 X 10^{-3\). The correct option is C.

In scientific notation, a number is expressed as a coefficient multiplied by 10 raised to a certain power.

The coefficient should be a number greater than or equal to 1 and less than 10. The power of 10 indicates the number of decimal places the original number should be moved to the left or right to obtain the given value.

For 0.0054, we can write it as 5.4 multiplied by 10 raised to the power of -3. This is because we move the decimal point three places to the right to obtain the value 5.4, and the power of 10 becomes -3 to indicate the decimal movement.

So, the number 0.0054 in scientific notation is  \(5.4 X 10^{-3\).
