Pick one part from the male reproductive system and one part from the female and tell me how
they're similar. please

They are similar a bit like this

It is true that the testicles are similar in shape to ovaries, but that is where those similarities end.  Males do NOT start as females.  All humans start out the same, asexual.  When hormones are introduced during development, the s-xual organs form.  If a female has too high of testosterone during development, they will be come a hermaphrodite and have what looks like both organs and same goes if males and  they actually begin life as the same organ structurally anyway. That's why it's so difficult to tell the sex of a very young fetus they all have a phallus which becomes a pen-s in males and a cli-oris in females. The gonads are all internal at that time. They become ovaries in females and descend and become testicles in males.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
