Genes are located on chromosomes and these chromosomes are passed into the gametes in sexual reproduction. If two genes are closely linked, it is likely that their positions on a chromosome are close together. This is why they are likely to be sent into the same gamete of the parent and inherited by the offspring.
Answer:
Intramuscular
Explanation:
Intramuscular is a method of administering injection directly into the muscles for effective functioning.
Long acting penicillin are administered intramuscularly because of penicillin sensitive microorganisms that are subsceptible to low serum levels which is associated with penicillin dosage in the body and penicillin Has low level of solubility therefore it is slowly released into the muscles sites.
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.
The correct answer is C. Trees provide oxygen for humans, so by reducing trees you reduce oxygen available for humans.
