According to the dichotomous key below, what are the distinguishing characteristics of a female mosquito of the genus culex? A. Pointed abdomen tip; antennae and palps shorter than proboscis
B. Pointed abdomen tip; antennae and palps longer than proboscis
C. Blunt abdomen tip; antennae and palps longer than proboscis
D. Blunt abdomen tip; antennae and palps shorter than proboscis

D.Blunt abdomen tip; antennae and palps shorter than proboscis

Explanation:

According to the data I found on research, on this type of mosquito, the Culex, or Culicine, females do present a blunt abdomen tip, which is different from the Aedes and other types of mosquito, palpi that are much shorter, and less bushy than in males either of their own type, or another type, and antennae with shorter, fewer hairs in them. The antennae and palps are shorter than the proboscis, as well. Knowing these factors help scientists to recognize the female mosquitoes of the Culex subfamily, from other females and from males of the same family, as well.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
