The characteristic of facilitated diffusion (passive transport) of a molecule across a membrane is E, all of the above.
How is molecule diffused across a membrane?Molecules can diffuse across a membrane in two ways: passive transport and active transport. Passive transport occurs spontaneously and does not require the cell to expend energy. Simple diffusion and facilitated diffusion are both forms of passive transport.
Facilitated diffusion is a type of passive transport, which means that it does not require energy input from the cell. One characteristic of facilitated diffusion (passive transport) of a molecule across a membrane is that it does not require energy input from the cell.

Two gases that plants must exchange with the air are: a. oxygen and nitrogen. b. oxygen and carbon dioxide. c. carbon dioxide and nitrogen. d. carbon dioxide and carbon monoxide.
Answers
i belive it is B. oxygen and carbon dioxide
Plants use carbon dioxide for photosynthesis and oxygen is a product of photosynthesis.
The two gases that plants must exchange with the air are oxygen and carbon dioxide. Oxygen is required for respiration while carbon dioxide is required for photosynthesis. The exchange of these gases is essential for the survival of plants and for maintaining the balance of gases in the atmosphere. Option B)
The two gases that plants must exchange with the air are oxygen and carbon dioxide. Plants consume carbon dioxide during photosynthesis and release oxygen back into the atmosphere. This process of photosynthesis occurs in the chloroplasts of the leaves and involves the absorption of sunlight and conversion of carbon dioxide and water into glucose and oxygen.
In the process of respiration, plants use oxygen to break down glucose and release energy. The waste product of respiration is carbon dioxide, which is released back into the atmosphere. This exchange of gases is vital for the survival of plants as well as for maintaining the balance of gases in the atmosphere.
Oxygen is important for the survival of all living organisms, including plants. It is required for respiration, which is the process of releasing energy from food. Carbon dioxide, on the other hand, is a waste product of respiration and is required for photosynthesis. The exchange of these two gases between plants and the atmosphere is essential for the survival of both. Therefore option B) is correct.

The answers include the following:
The two clues you can give to make them easily distinguish between bacteria and yeast is that yeast has a single nucleus per cell, while bacteria does not have a nucleus.The two clues which can make them confused so that they can’t. decide whether they are bacteria or plant cell is that they both possess cell wall.What is Yeast?This is an organism which belongs to the fungus kingdom and is an eukaryotic, single-celled microorganisms with the presence of one nucleus which is what differentiates it from bacteria as it possesses none.
Bacteria and yeast have cell wall which is the organelle responsible for maintaining their structural integrity while bacteria has no nucleus and yeast has one which differentiates them which is therefore the reason why it was chosen as the correct answer.

A potential difference of 100 mV exists between the inner and outer surfaces of a cell membrane. The inner surface is negative relative to the outer surface. How much work is required to eject a positive sodium ion (Na ) from the interior of the cell
Answers
Answer:
1.602 × 10⁻²⁰ J
Explanation:
Since the sodium ion Na has a positive charge, the work done in moving it from the interior of the cell to the exterior of the cell is W = qΔV where q = charge on sodium ion = +1 and ΔV = potential difference between inner surface of the cell and outer surface of the cell. Since the inner surface of the cell is negative relative to the outer surface, the sodium ion moves from a lower potential to a higher potential. So, the potential difference is ΔV = + 100 mV = 0.1 mV = 10⁻¹ V
Also, q = +1 which is one unit of charge. So, q = +e where e = electron charge = +1.602 × 10⁻¹⁹ C
So, W = qΔV (Note that the work done is positive since we have to input work into the cell to move a positive charge from lower to higher potential)
So, substituting the values of the variables into the equation, we have
W = qΔV
W = +1.602 × 10⁻¹⁹ C × 10⁻¹ V
W = +1.602 × 10⁻²⁰ J

State 5 effects of exercise with varying intensity on the immune system.
Answers
Varying intensity of exercise can result in different effects on the immune system, such as increased natural killer cell activity, decreased inflammation, improved antibody response, increased white blood cell count, and increased cytokine production.
What are the 5 effects of exercise with varying intensity on the immune system?Here are 5 effects of exercise with varying intensity on the immune system:
Moderate Intensity Exercise: Regular moderate intensity exercise has been shown to enhance immune function by increasing the circulation of immune cells and antibodies in the body.
High Intensity Exercise: Short-term high-intensity exercise can lead to temporary suppression of the immune system. This is because intense exercise causes stress on the body, leading to the release of stress hormones that can suppress immune function.
Chronic Intense Exercise: Prolonged, intense exercise can lead to a decrease in immune function and increase the risk of infection if the body is not given adequate time to recover.
Resistance Training: Resistance training has been shown to boost immune function by increasing the production of immune cells.
Aerobic Exercise: Aerobic exercise has been shown to boost the immune system by increasing the number of natural killer cells, which are a type of immune cell that helps to fight off infections. Aerobic exercise can also increase the circulation of immune cells and antibodies in the body, improving immune function.

C.
Lighter colored mice had more dominant genes in their new habitat.
D.
Lighter colored mice were more likely to avoid predators and to reproduce.
Answers
Lighter colored mice were more likely to avoid predators and to reproduce. Therefore, option (D) is correct.
The lighter brown coloration of the deer mice in the Sand Hills of Nebraska is likely an adaptation that provides them with a survival advantage in their specific habitat. The light, sandy soil in the area may offer better camouflage for lighter colored mice, making them less visible to predators and increasing their chances of survival.
As a result, these mice would have a higher likelihood of successfully reproducing and passing on their lighter coloration traits to future generations.
