Answer:
Major difference between active transport and facilitated difusion is:
Active transport moves substances against the concentration gradient.
Facilitated diffusion moves molecules through the plasma membrane.
Explanation:
- Active transport involves the transport of molecules against the concentration gradient.
- Since molecules move from lower concentration to higher concentration this mode of transport needs energy.
- Facilitated diffusion do not require energy but need some other molecule or carrier protein to transport the molecules across the membranes.
- In facilitated diffusion, the molecules move from their region of higher concentration to the region of lower concentration.
The <span>eukaryotic cells do not contain any organelles such a nucleus in particular. The difference in their structures for prokaryotes and eukaryotes will also include the presence of chloroplasts and mitochondria. Also, structures such as cell wall and chromosomal DNA structures are also some of the difference in the two types of cells. The answer to the second question is C.

ANSWER
A water molecule consists of one oxygen atom bonded to two hydrogen atoms by covalent bonds. Since oxygen is more electronegative as compared to hydrogen atoms, the shared electrons are attracted towards the oxygen atom. This imparts partial negative charge to the oxygen atom and partial positive charge to hydrogen atoms. The overall effect is making the water molecular a polar one. The presence of free hydrogen atoms makes water molecule to form hydrogen bonds with other water molecules and with other polar molecules.
explanation: what i found on google
Answer: i know the answer but i just cant think off the top of my head i am sorry i really want to answer though but if i figure it out i will tell you
Explanation:
Alpha particles bouncing off gold foil in Rutherford's gold-foil experiment which developed the understanding of the structure of the atom, expanding upon Thomson's research with cathode rays.
