Fungi are interesting organisms that interact with humans in many ways. Yeasts arefungi used in the food industry to produce products such as bread and certain beverages. Some fungi are valuable in medicine. For example, the drug cyclosporine, which is capable of suppressing the response of the immune system to foreign antigens, and the antibiotic penicillin are both products from fungi. Other fungi are less welcomed by humans. The irritation of athlete’s foot is caused by a fungus, and a number of allergies are caused by reproductive spores released by fungi. Explain the difference between an infection caused by a fungus and an allergy caused by a fungus.

In order to protect off of aquifers near landfills material is placed under the soil to prevent pollution which property must the protective material process

Answers

Answer: Permeability. 

This property allows liquids to pass through the material but also filters out pieces of garbage and other pollutants. In aquifers, permeable rocks or synthesized permeable material are used so that trash, or clay will not leak into the groundwater. 

The answer is impermeability. The protective materials prevent the leakage and seepage of contaminated water (such as those of battery acid and household cleaners), by gravity, to the water table in the aquifer. If this is not done, contamination of groundwater may result and cause a public health disaster when the contaminated water is used for consumption when it reaches water wells.

Which describes the mating of organisms that have different homozygous alleles for a single trait? monohybrid cross dihybrid cross homozygous cross heterozygous cross

Answers

The term which describes the mating of organisms that have different homozogous alleles for a single trait is monohybrid cross. The 'mono' refers to the singular trait while 'hybrid' refers to the crossing of two different parents. Monohybrid cross yields offsprings that have one dominant and one recessive allele for that particular gene in question.

Monohybrid cross describes the mating of organisms that have different homozygous alleles for a single trait. Thus, the correct option is A.

What is Trait?

A trait may be defined as the phenotypic appearance or manifestation of the desired characters that are selected for the study.

A Monohybrid cross may be defined as a cross between parents that differed in a single characteristic. The F2 phenotypic ratio of the monohybrid cross is 3:1, while the F2 genotypic ratio is 1:2:1.

Therefore, it is well described above.
