Answer:
The movement of glucose across the cell membrane through facilitated diffusion one of the form of passive transport because it does not require the energy to transport the glucose molecule across the cell membrane and the transport is along the concentration gradient.
In facilitated diffusion the passage of molecules if facilitated by a carrier protein or a channel protein. The rate of transport of molecules in facilitated diffusion is greater than simple diffusion.
Through facilitated diffusion, some polar and charged molecules can cross the cell membrane without the expense of energy.
Answer:
A
Explanation:
Since the water occupies a bigger space the organisms that reproduce in freshwater have a bigger area to reproduce.
Answer:
A. Earthquake
Explanation:
When plates slide past each other, the edges of these are earthquake zones. Earthquakes are formed but not volcanoes.
I am going with x-rays; it is the most visible to the naked eye out of all the choices.
The answer is; C
Plasmids are conferred through horizontal gene transfer in bacteria. The ‘male’ bacteria develops a structure called pili that then attaches to the ‘female’ bacteria. It then transfers it’s replicated plasmid to the ‘female’ bacteria in a process called conjugation. This bacteria will hence have desirable traits that are coded for by the transferred genetic material ,such as antibiotic resistance, after a process called recombination.
