Answer:

1. Many vertebrates have teeth, and chewing (mastication) breaks up food into small particles, expanding its surface and mixes it with fluid secretions, which makes it possible to digest. Teeth are located in the mouth of animals, where the digestive process initiates.

2. The stomach, which resembles a bag-like shape, can either fold up when empty and expand like a balloon when it fills up with food. By doing this, the area of activity of the gastric juice is expanded, increasing the efficiency of the digestion. Food enters the stomach from the esophagus.

3. The villi and microvilli present in the epithelial wall of the small intestine, are fingerlike projections that greatly enhance the surface area of the small intestine. In humans, this surface area is 300 square meters and it is over this large surface that the products of digestion are absorbed.

Compare and contrast p-dependent and p-independent termination of transcription in prokaryotes.
iVinArrow [24]
Compare and contrast two mechanisms for transcriptional termination in bacteria.

(rho)p-dependent termination: requires rut (rho utilization site), rho protein binds, moves towards 3' end, DNA encodes GC rich for stem loop, RNApoly pauses, rho protein catches up and separates RNA-DNA hybrid

(rho)p-independent termination: Uracil-rich sequence causes RNApoly to pause, stabilized by NusA near open complex RNA exit, UA bonds to weak to hold, DNA-RNA hybrid dissociates AKA intrinsic termination
