What do you think would happen if we touched the posterior part of the worm (the rear), instead of the anterior part (mouth)?
Most annelids, like earthworms, have a simple brain that connects to their skin and muscles through simple nerves. Along with this there are chemo receptors on the skin which help the worms to taste things and also act as tiny sense organs that can detect chemicals. The body muscles respond to touch and contract when the sensation travels to the 'brain'.
If the posterior part of the worm is touched, the muscles contract and the rear part of the body curls and is pulled forward. In other words, the body contracts and pulls away from the touch.

What do you think would happen if you failed to vortex your homogenate sample before removing an aliquot for an assay? In this experiment, we sought to measure glycogen and free glucose in tissue homogenates, using spectrophotometry to detect levels of glucose in tissue samples. We inferred the amount of glucose stored in glycogen using reaction catalyzed by amyloglucosidase. A control reaction was without amyloglucosidase, this measured free glucose or not part of glycogen.
What vessel in the posterior compartment would particularly contribute to collateral circulation? Where do you feel the pulse of the anterior tibial artery? Where would you palpate the pulse of the dorsalis pedis artery?
Regarding studies in early development of vertebrates (frog and mouse): A) What do you think is the most striking similarity between the way these organisms specify their anterior structures? B) What do you think is the most striking difference in the way these organisms specify their anterior structures? C) What are the similarities and differences between these mechanisms and the way that Drosophila specifies its anterior/posterior structures?
Based on the chemical properties of esters, what do you think would happen if a reaction was heated at too high of a temperature for too long?
what do you think would happen if an oil spill occurred that killed off most of the phytonplankton ans zooplankton?
EXPERIMENT 1: What do you think will happen to the temperature if you used 75 mL of HCl and 75 mL of NaOH instead of the 10 mL each you used in Experiment 1?
What do you think would happen if the Trump administration threw out the entire Affordable Care Act?
Assuming it would dissolve, what you think will happen to the absorption band of MnO4 - if the ion was dissolved in acetonitrile instead of water? Briefly explain your answer
what do you think will happen to the variety of colours as the allele frequency of the dominant allele at each of the ambiguous loci increases? We will begin to see fewer individuals with the homozygous recessive genotypes and therefore the variety of colours will decrease. We will the same number of individuals with the homozygous recessive genotypes and therefore the variety of colours will remain the same. We will begin to see more individuals with the homozygous recessive genotypes...
