Mycorrhizae help plants to take in minerals such as phosphate and other soil minerals, including zinc and copper.
Mycorrhizae is a symbiotic relationship that some plants' root systems have with fungi. The fungal hyphae either surround the developing roots in a dense network or enter the root cells. The fungal hyphae's large surface area aids in increasing the soil's ability to absorb water and minerals. They receive sugar and nitrogenous compounds from the host plants in exchange. Some plants must participate in the mycorrhizal association. For example, Pinus seeds do not sprout and grow without mycorrhizal fungi.
What are types of Mycorrhizae?
Endomycorrhizae and ectomycorrhizae are the two different types of mycorrhizae.
Endomycorrhizae is a type of mycorrhiza that embed mycelium within the root tissue instead of forming a sheath around the plant roots, which is known as a mantle from which the hyphae grow. Ectomycorrhizae are a type of mycorrhiza that do the opposite.
Endomycorrhizae is found in the roots of most terrestrial plants and is characterized by mycelium that is embedded within the root tissue as opposed to forming a sheath around it.

During bronchoconstriction, the smooth muscle that lines the bronchial passages contracts, resulting in a decrease of the internal diameter of the airway and an increase of:________
During bronchoconstriction, the smooth muscle that lines the bronchial passages contracts, resulting in a decrease of the internal diameter of the airway and an increase of____resistance to airflow ____
What is bronchoconstriction ?When the smooth muscle around the bronchi and bronchioles constricts, wheezing and shortness of breath result.
When the muscles lining the airways become tense, the process of bronchoconstriction begins. Your airway narrows as a result of the bronchi and bronchioles being squeezed. Numerous airway stimuli can constrict the airway in sensitive patients.Bronchodilators are typically the first step in bronchospasm treatment. There are several ways to get this drug, including pills, nebulizer solutions, and inhalers.

During strenuous exercise, anaerobic conditions can result if the cardiovascular system cannot supply oxygen fast enough to meet the demands of muscle cells. Assume that a muscle cell’s demand for atp under anaerobic conditions remains the same as it was under aerobic conditions. What would happen to the cell’s rate of glucose utilization?.
During strenuous exercise, anaerobic conditions can result if the cardiovascular system cannot supply oxygen fast enough to meet the demands of muscle cells. Assume that a muscle cell’s demand for ATP under anaerobic conditions remains the same as it was under aerobic conditions. Under such circumstances, the cell's rate of glucose utilization would increase a lot.
In the field of science, aerobic respiration is a kind of respiration in which glucose is broken down to release energy in the presence of oxygen. However, if oxygen is not present, then the breakdown of glucose during such circumstances is referred to as anaerobic respiration.
There are 38 molecules of ATP that are formed as a result of aerobic respiration. As a result of anaerobic respiration, only 2 ATP molecules are formed. Hence, if a muscle cell's demand for ATP remains the same in aerobic and anaerobic respiration, then an excessive amount of glucose will be used to meet the requirement in anaerobic conditions.

What is the conductance of a 1.0-mm-diameter, 10-cm-long blood vessel filled with blood?
The conductance of the blood vessel is 4.91× 10-6 ohm⁻
Given, here the length of blood vessel, L = 10cm.and the diameter, D = 1mm or 0.1 cm
Then, radius is equals to 0.1/2 = 0.05cm
Now, we calculate cross sectional area, which equals to πr2
A=πr² = π(0.05)²
We know that , the resistivity of blood ties between 80 ohm cm to 240ohm cm.
Therefore, The average resistivity, ρ= 80+240/2ohm cm = 160ohm cm.
Now, we calculate the resistance of the blood by the formula,
R= ρ l/A
R= 160ohm cm × 10cm/ π × (0.05) 2
R= 1600/ 7.854× 103cm2
R= 203.72× 103 ohm.
Now, we caclulate conductance and we know that it is reciprocal of resistance.
So, The conductance is, G= 1/R
G= 1/203.72× 103 ohm.
G= 4.91× 10-6 ohm⁻
Any conductor, including a lightbulb, will block the flow of an electric current; this obstruction is known as electrical resistance and is represented by the letter R. Conductors emit heat when current flows through them because all materials have an electrical resistance.

When sperm and ovum unite at conception, the resulting _____________ will again have 46 chromosomes.
A simulation is run exploring the random motion of particles and its role in diffusion. At the start of the program, there are 20 blue spheres on one side of the membrane and 10 red spheres on the other side. After a period of time, the distribution of spheres reaches an equal number independent of each other, so that there are 10 blue spheres and 5 red spheres on either side of the membrane. What evidence suggests that diffusion results in a dynamic equilibrium across the membrane?.
According to the facts, diffusion produces a dynamic equilibrium across the membrane, where the red and blue spheres continue to move in opposite directions.
Diffusion produces a gradient in which molecules and atoms move from one concentration to another. Essentially, it is a procedure designed to preserve equilibrium. The process continues to ensure that there is equal concentration everywhere.
For further explanation, see the image below that has been attached:
The blue spheres are more prevalent on the left side of the first diagram, while the red spheres are more prevalent on the right side.
20 blue spheres are on the left and right sides of the diagram in the question, and 10 red spheres are on the right side. Because the colored spheres are not distributed equally on the two sides of the membrane, some blue spheres will move from the left side (where there is a higher concentration) to the night side (lower concentration).
Additionally, a few red spheres will move from the left side's lower concentration to the night side's higher concentration in order to achieve an equal distribution of red and blue spheres on both sides.
Seek out the second diagram in the question where arrows indicate a change in concentration from higher to lower.
On the left, there are a total of 20 blue spheres. Therefore, 10 blue spheres from the left side of the spheres will move to the night side to achieve equal distribution.
On the right side, there are a total of 10 red spheres. Therefore, five red spheres on the right side of the board will move to the left, distributing the spheres equally.
The second image in the question provides an illustration of the aforementioned distribution.
Look for the arrows that depict the spheres moving.
The atoms and molecules are now free to move, which means they might once more result in a loss of equal concentration. In order to maintain an equal number of red and blue spheres on both sides, the red and blue spheres will therefore move continuously.
On the third diagram, look for the arrows. It demonstrates that both the right and left sides of the blue molecules or atoms are moving. Red spheres are also moving to maintain equal concentration, Similarly, this leads us to the conclusion that even when the red and blue spheres are in equilibrium, they are still moving to the ether side. Thus, despite being in equilibrium, the red and blue spheres continue to move in opposite directions.
