Reil [10]3 years ago

Answer:

Antibiotics, also known as antimicrobial drugs, are drugs that fight infections caused by bacteria. Alexander Fleming discovered the first antibiotic, penicillin, in 1927. After the first use of antibiotics in the 1940s, they transformed medical care and dramatically reduced illness and death from infectious diseases.

The term "antibiotic" originally referred to a natural compound produced by a fungus or another microorganism that kills bacteria which cause disease in humans or animals. Some antibiotics may be synthetic compounds (not produced by microorganisms) that can also kill or inhibit the growth of microbes. Technically, the term "antimicrobial agent" refers to both natural and synthetic compounds; however, many people use the word "antibiotic" to refer to both. Although antibiotics have many beneficial effects, their use has contributed to the problem of antibiotic resistance.

Antibiotic resistance is the ability of bacteria or other microbes to resist the effects of an antibiotic. Antibiotic resistance occurs when bacteria change in some way that reduces or eliminates the effectiveness of drugs, chemicals, or other agents designed to cure or prevent infections. The bacteria survive and continue to multiply causing more harm.

Given the information below, answer the following questions, assuming complete dominance. Tongue rolling is a dominant trait. If
adelina 88 [10]

Answer:

The chance that their <u>child will not be able to roll his tongue will be zero</u>.

The chances to have a child with tongue rolling ability is 100%.

Explanation:

In complete dominance, a dominant gene completely manifests over a recessive gene. If tongue rolling is a dominant trait, this means that the gene that expresses this trait is dominant over the recessive one that does not allow the person to roll the tongue.  

If the gene for tongue rolling is called T, then a person that is homozygous dominant for this trait will have the following genotype: TT. If the person is heterozygous for this trait, the genotype will be Tt. And if a person is homozygous recessive for the trait, this person´s genotype will be tt.

When two homozygous dominant individuals mate, their chances to have a child with tongue rolling ability is 100%.

This is:    

Parental)         TT   x   TT

Gametes)     T   T       T   T

Punnet Square)                  T                 T

                                T        TT             TT

                                T        TT             TT

F1)  Genotype: 100% TT, or 4/4 TT

      Phenotype: 100% Tongue rolling capable.
