Answer:
RrYy (F1 generation)
Explanation:
This is a typical dihybrid cross involving two genes in the pea plant; one coding for seed colour and the other for seed shape.
According to Mendel's law of dominance, an allele is capable of masking another allele in a gene, the allele that masks or is expressed is called the DOMINANT allele while the allele being masked is called RECESSIVE allele.
Homozygosity of a gene refers to it having the same type of alleles while heterozygosity refers to having different alleles.
In this example, allele for Round (R) and Yellow (Y) pea is dominant over the allele for Wrinkled (r) and green pea respectively.
Homozygous round green pea (RRyy) crossed with Homozygous wrinkled yellow (rrYY) will give rise to a heterozygous round yellow (RrYy) F1 offsprings.
Answer:
Fomepizole with ethanol
Explanation:
The antidote for ethylene glycol poisioning is the administration of fomepizole with ethanol.
Ethylene glycol (antifreeze) is a poisonous, colorless and sweet tasting liquid which is usually used for antifreeze formulations. Drinking or liking of ethylene glycol deliberately or unintentionally can result in ethylene glycol poisoning. The poisoning can be treated by stabilizing the affected animal, followed by the administration of the antidote; fomepizole with ethanol. This is the most preferred antidote. Hemodialysis, sodium bicarbonate and magnesium may also be used to treat the affected animal.
Answer:
Explanation:
The Julia butterfly (or dryas iulia) isn't trying to cheer up the turtle, it is actually a symbiotic relationship between the two creatures. The butterflies undertake the process of lachryphagy, or 'tear feeding' as a way of gaining much needed nutrition.
