An aquatic arthropod called a cyclops has antennae that are either smooth or barbed. the allele for barbs is dominant. in the same organism, resistance to pesticides is a recessive trait. make a "key" to show all the possible genotypes (and phenotypes) of this organism.

Lets consider the allele for barbs to be B and the allele for smooth to be 'b'. The possible genotypes and phenotypes will be

BB ( homozygous dominat barbs)

Bb ( heterozygous barbs)

bb ( smooth)

Lets consider the resistant allele to pesticide as 'r' and the non- reistant as 'R'.

The possible genotypes and phenotypes will be

RR (non- resistant)

Rr (non- resistant)

rr (resistant)

hi there!

answer: b. nucleolus

explanation: nucleolus is a structure in the nucleus are ribosomes are made.

hope this you!

have a nice day! : )

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
