Komodo dragons can reproduce both sexually and asexually depending on the environment. They can do this because of Parthenogenesis (Parthenogenesis is a natural form of asexual reproduction in which growth and development of embryos occur without fertilization. In animals, parthenogenesis means the development of an embryo from an unfertilized egg cell.)
I am pretty sure the answer is A but i'm not sure
Answer:
Despite a generally high security standard, <u>accidents can still happen.</u> It is technically impossible to build a plant with 100% security. A small probability of failure will always last. The consequences of an <u>accident would be absolutely devastating both for human being as for the nature.</u>
Nuclear power plants as well as nuclear waste could be<u> preferred targets for terrorist attacks. </u>No atomic energy plant in the world could withstand an attack. Such a terrorist act would have <u>catastrophic effects for the whole world.</u>
Answer:
The two main reasons are nonpolar core of the bilayer and the active transport.
Explanation:
The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.
If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.
One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>
