Answer:
A.
Explanation:
bacteria have cell membranes to mimic a normal cell. this protects the bacteria from being consumed by the body's natural defences .
Yes, you can determine which of two unknown elements has the larger radius.
What is the radius?
In classical geometry, a radius of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
An element with an atomic number that is 20 greater will be bigger because when an element is bigger, it will have more particles (electrons, protons, and neutrons) which means that the atom will get bigger which will cause it to have a bigger radius.

Sympathetic and parasympathetic fibers serve the same organs, but they have opposite effects. The sympathetic system prepares the body for intense activity and fight or flight. The parasympathetic system relaxes the body, controls homeostasis and resting and digesting. It is the feed and breed system.
The question is incomplete as it does not have the options which are:
Protein carrier
Lipid carrier
Porin carrier
All of the choices are correct
Answer:
Protein carrier
Explanation:
The transport of molecules through diffusion can be passive or facilitated. The facilitated diffusion in which the molecules are facilitated to cross required tow type of protein channels which are the channel proteins and the carrier proteins.
The carrier proteins are the transmembrane proteins which are specific for ions and to transport the molecules change their shape of conformation. The change in the shape is responsible for the release of ions on the other side of the membrane.
Thus, Protein carrier is correct.
