False, science aims to explain and understand. Science as a collective institution aims to produce more and more accurate natural explanations of how the natural world works, what its components are, and how the world got to be the way it is now.
Active transport is the moving of molecules across the membrane of the cell against the concentration gradient with the use of ATP.
Low to high concentration. Concentration gradient is the diffusion (movement of molecules from regions of low concentration) from high to low with the gradient. Active transport is from low to high, against the gradient.
A membrane bound nucleus (or just a nucleus in general)
*This is to help figure it out, you don't learn if I flat out give you the answer*
The new viruses burst out of the host cell during a process called lysis, which kills the host cell. Some viruses take a portion of the host's membrane during the lysis process to form an envelope around the capsid.
