Phospholipid bilayers are NOT stabilised by: a. van der Walls forces b. covalent bonds c. hydrogen bonds d. ionic bonds e. hydrophobic interactions - b. covalent bonds A transmembrane protein has the following properties: it has two binding sites, one for solute A and one for solute B. The protein can undergo a conformational change to switch between two states: either both binding sites are exposed exclusively on one side of the membrane, or both are exposed exclusively on the ot...

cell division division of a parent cell into daughter cells centriole structure that helps to form the spindle spindle microtubule structure that separates chromosomes during mitosis cell cycle cell grows, prepares to divide, then divides to start growth process again; interphase + M phase telophase last phase of mitosis, chromosome are in two new cells and nuclear membranes start to reform interphase cell grows, performs its normal functions, and prepares for division; consists of G1, S...

sister chromatids - ️️two copies of a duplicated chromosome attached to each other by proteins at the centromere and, sometimes, along the arms; when joined, two of these make up one chromosome. usually separated during mitosis or meiosis II centrioles, centrosome - ️️a structure present in the cytoplasm of animal cells that functions as a microtubule-organizing center and is important during cell division is a _______. it has two _______, which are structures in an animal cell comp...

How is cell division possible in eukaryotes versus prokaryotes? - Answer-*Eukaryotes* - Mitosis - > somatic cells - Meiosis -> gametes *Prokaryotes* - Binary fission What is the outcome of Mitosis/Cytokinesis? - Answer-A parent cell is divided to create two identical daughter cells to the parent and each other (clones) What are the three functions of Mitosis? - Answer-1) Growth 2) Repair/ Replacement 3) Asexual Reproduction What is a chromosome? - Answer-- A structure carrying ge...
