Nematodes are a model organism for many eukaryotic processes. These worms are often used in laboratory investigations regarding animal reproduction. One variety of mutant nematode cannot lay eggs in order to reproduce. However, the addition of the
neurotransmitter serotonin provides a mechanism that allows the mutant worm to lay eggs. The results of this study indicate that
multiple organ systems are involved in egg laying. Which statement best describes the interaction between organ systems in this
scenario?
es -))
A)
B)
The respiratory and the reproductive systems interact to produce eggs in
the nematode.
The respiratory and the circulatory systems interact to produce eggs in the
nematode.
The nervous and the circulatory systems interact to produce eggs in the
nematode.
The nervous and reproductive systems interact to produce eggs in the
nematode.
D)

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.

fossil's are like over rated rocks like low key not gonna lie i don't get why we can't just call them old rocks like for real i mean i call my grandpa and grandma that smh
