A polymer is formed by linking of many monomers units by different kinds of bonds. In carbohydrates, this bond is a glycosidic bond. In the case of proteins, it is a peptide bond. In nucleic acids, the bond is an ester linkage. The monomers link together by two mechanisms: addition polymerization, or condensation polymerization.
Answer:
The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature to increase the surface area for reactions (electrochemical gradient) by accommodating protons pumped into it by the proton motive force(PMF) from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.
Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.
Explanation:
The falciform ligament separates the<u> a. right and left lobes of the liver.</u>
Explanation:
- The falciform ligament is a ligament that attaches the liver to the front body wall, and separates the liver into the left medial lobe and left lateral lobe.
- The falciform ligament is a broad and thin peritoneal ligament. It is sickle shaped and a remnant of the ventral mesentery of the fetus.
- The falciform ligament droops down from the hilum of the liver.
- It contains between its layers a small but variable amount of fat and its free edge contains the obliterated umbilical vein and if present, the falciform artery and paraumbilical veins.
- The falciform ligament divides the left and right subphrenic compartments but may still allow passage of fluid from one to the other.
- The falciform ligament stretches obliquely from the front to the back of the abdomen, with one surface in contact with the peritoneum behind the right rectus abdominis muscle and the diaphragm, and the other in contact with the left lobe of the liver.
Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.
Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.
