The right answer is facilitated diffusion.
Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.
<span>If it loses that 1 electron (0 electrons, 1 proton, 1 neutron) it become an ion that is positively charge because it has more protons than electrons. [Ignore the neutrons] </span>
<span>If it gains an electron (2 electrons, 1 proton, 1 neutron) it becomes an ion that is negatively charge because it has more electrons than protons </span>
<span>A molecule - when 2 or more "different" elements combine or when 2 or more of the "same" elements combine </span>
<span>1 proton 1 electron <----- that is considered to be neutral </span>
<span>3 protons, 3 electrons <----- neutral </span>
<span>5 protons 5 electrons <----- neutral </span>
<span>6 protons, 5 electrons <-- positive ion [more protons than electrons] </span>
<span>5 protons, 8 electrons <--- negative ion [more electrons than protons] </span>
The normal, or emmetropic, eye accommodates properly.
The correct answer is - limestone.
On the image, it seems that we have a representation of rock formations in a cave. They are evidently weathering. According to the manifestation of the weathering, the color of the rocks, and that it is most probably a cave, the chances are mostly likely that it is a limestone.
The weathering appears as a result of the water. The limestone is a sedimentary type of rock, thus it doesn't have strong structure. The water is able to gradually penetrate through it, making holes in it, and little by little weather it. In this way we have the formation of the water reservoirs, springs, cave systems.
Answer:
because more is being forced through
