Answer:
Crossing Over. Crossing over, or recombination, is the exchange of chromosome segments between nonsister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
If you must leave an injured or ill athlete unattended to get additional help, and you do not suspect an injury to the head, neck or back, then you should ask not to move while going for help, either by calling 911 or looking for someelse to help, once contacted help return immediately with the injured person and check that no threat has appeared to his life and provide care while the help gets there.
Hey You!
It lasts about 90 minutes for a normal person.
Answer;
-Pumps require energy for transport because they move material against an electrochemical gradient, but channels and carriers do not use energy because they only facilitate diffusion down a molecule's or ion's electrochemical gradient.
Explanation;
-Permeability is conferred by two classes of membrane proteins, pumps and channels. Pumps use a source of free energy such as ATP or light to drive the thermodynamically uphill transport of ions or molecules. Pump action is an example of active transport.
-Channels, in contrast, enable ions to flow rapidly through membranes in a downhill direction. Channel action illustrates passive transport, or facilitated diffusion.
