Answer:
A) Channel Protein
Explanation:
Channel proteins span the membrane and make hydrophilic tunnels across it, allowing their target molecules to pass through by diffusion.
Channels are very selective and will accept only one type of molecule to transport
A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly.
The value of x = 4
<u>Explanation:</u>
RS = 4(x-3)+6
= 4x-12+6
= 4x-6
RT = 5(2x-6)
= 10x-30
Showing left hand side is equal to right hand side.
4x-6 = 10x-30
Divide both left hand side and right hand side by 2, we get:
2x-3 = 5x-15
Rearrange both the sides
-3+15 = 5x-2x
12 = 3x
x = 4
Thus, the value of x is 4
To clearly view the morphology of the prokaryotes, one needs a microscope with higher resolution i.e magnification of ×100. Use of oil for this purpose is important because it reduces the refraction of light as it travels from air to glass. this process increases the resolution of the microscope making it possible to view morphology of bacteria.
Answer:
3900
Explanation:
100 meters x 39 worms per meter = 3900 worms per square meter :)
B is a possible hypothesis for testing the experiment
