In a group of bitter melon plants, some individuals have dark brown seeds and others have light brown seeds. In this group, the gene for the seed color trait has two alleles. The allele D is for dark brown seeds, and the allele d is for light brown seeds. A certain bitter melon plant from this group has dark brown seeds. This plant has one allele for dark brown seeds and one allele for light brown seeds.

Based on this information, what is this bitter melon plant's phenotype for the seed color trait?

(A.) Dd (B.) dark brown seeds

i think it is true in my reasonment ..

answer: decrease

a limiting factor is the one which decrease the abundance, distribution and causes extinction of the population of species in a ecosystem. here, predators including hawks, owls and snakes are the limiting factor for the population of mexican free tailed bat.   although bats are nocturnal animals as they forge for food at night these predators also may remain active during night which can decrease the population of the mexican free-tailed bats. also, these bats eat only one type of insects that are moths. the food can also be a limiting factor as all 400 members are dependent upon same type of food needs that are moths. the decrease in the moth population can cause decrease in population size of the mexican free-tailed bats.

therefore, the scenarios will most likely to decrease the population size of the mexican free-tailed bats.  

b tumor cells have a cell wall instead of a membrane

explanation:

tumor cells different from normal cells because tumor cells have a cell wall instead of a membrane.

it's diluted or concentrated

in a diluted solution, you can add a lot more solute but in concentrated only a little more can be added
