Answer:
llbb
Explanation:
<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>
Generally, epithelial cells serve the function of protection of the inner layers of the structure they are on. The fact that these columbar epithelium and transitional epithelium cells have smooth walls and are dome shaped allows them to stretch. This stretching helps the bladder retain more urine than it would be able to if the epithelial cells were rigid.
The answer is; burning unleaded gasoline
Unleaded gasoline does not reduce carbon emissions. The lead was added to fuel ideally for vehicles to reduce the knocking of engines. Lead in its chemical structure also increased fuel octane levels. When lead was discovered to be a neurotoxin, it was banned as an additive in fuel in most countries.
