How does temperature change with elevation and latitude
UNO [17]
When altitude increases, air temperature decreases because when there is an increase in altitude, there is a decrease in air pressure. When air pressure decreases, air cools down. Latitude affects temperature because the closer you are to the equator, the more intense the sun will be.

All the offspring of a cross between a tall pea plant and a dwarf pea plant are tall. This means that the allele for tall plants
Olenka [21]

Answer:

All the offspring of a cross between a tall pea plant and a dwarf pea plant are tall. This means that the allele for tall plants is <u>DOMINANT OVER</u> the allele for dwarf plants.

Explanation:

Mendel's law of dominance state that the heterozygous genotype expresses only one allele of a gene out of the two alleles present together. The allele that is expressed in a heterozygous genotype is said to be the dominant one as it does not allow the expression of another allele of the gene.

The allele of a gene that is not expressed in the presence of its dominant allele is said to be the recessive one. Under such conditions, a heterozygous genotype expresses the dominant phenotype. When a tall and dwarf pea plants are crossed, all the F1 progeny is tall. This means that the allele for the tallness is dominant over the allele for the dwarfism.
