A human DNA sequence is amplified by PCR in a population sample, and we observe five different alleles of 220 bp, 224 bp, 228 bp, 232 bp and 236 bp in length. This sequence is an example of a (choose one):
O 1.DNA profile
2. Minisatellite
O 3. SNP
4. Short tandem repeat (STR)

Wich organism obtains its energy from dead or decaying matter

Which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.which statements about the fluid mosaic structure of a membrane are correct? select the three correct statements.the framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.the diverse proteins found in and attached to membranes perform many important functions.the kinky tails of some proteins keep the membrane fluid by preventing the component molecules from packing solidly together.membranes include a mosaic, or mix, of carbohydrates embedded in a phospholipid bilayer.
