Answer: The correct answer is- This relationship is one of example of mutualism.
Mutualism can be described as a biological interaction between two species that live in close association with each other in a way that both the partners are benefited from each other. It is a type of symbiotic relationship.
Lichen shows mutualistic relationship between algae and fungus, where photosynthetic algae provides food source to the fungi and fungi in return provides protection to algae as well as provides nutrients from the surrounding.
Thus, it is an example of mutualism.
b. . a polygenic trait that is influenced by the number of alleles present
c. . a codominant trait that is expressed more often when more dominant alleles are present
d. . a dominant trait that depends on the presence of only one of many dominant alleles
The answer is b. a polygenic trait that is influenced by the number of alleles present.
There are three genes linked to a common form of glaucoma, so it must be the polygenic (meaning more than one gene included) trait. The polygenic traits are influenced by the number of alleles. In this case, there are more than 20 genetic loci which means there must be a great number of alleles for all loci.
Vitamin A and B are crucial for maintaining healthy eyesight along with following a balanced diet to ensure the supply of these nutrients which are not synthesized by the body.
To maintain healthy eyesight, you would take vitamins that are essential to this function. Particularly, Vitamin A and Vitamin B play important roles. Vitamin B helps maintain eyesight while vitamin A is critical to the development of bones, teeth, and skin, enhances the immune system, contributes to fetal development and gene expression, and importantly, helps maintain eyesight. It's important to note that the body does not synthesize these vitamins on its own. Hence, consumption of a balanced diet containing a variety of foods is of utmost importance to ensure a supply of these essential nutrients.

In thanks to the cell wall, the appearance of a plant cell does not change when water is plentiful and is therefore normal.
A cell wall is a structure on the outskirts of most plantcells. The density of the wall can change from time to time, but this wall is often rigid. This cell wall functions to provide the cell with protection and structural support, as well as help it withstand mechanical pressures.
The cell wall helps the cell in withstanding a form of mechanical pressure known as turgor pressure exerted by the vacuole when the plant absorbs a great amount of water. In this way, the cell wall helps in withstanding water pressures in hypotonic solutions. In addition, it also prevents the shrinkage of the cell in hypertonic solutions from exceeding a certain limit.
