Answer:
Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.
Explanation:
Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.
Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.
In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.
Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.
Well new species can come and live there and some animals may have new food but the disadvantage is some of the animals ill die that lived there because of the changes...i hope this helped you
The leaves of the plant compared to the plants around it are bigger because they are being token care of and watered and fed while the others take care of them selves also they are different types of plants :)
D because kg is mass and cubic cm is volume which Density = Mass / Volume
Answer:
It Depends...
Explanation:
The null hypothesis is that statement that we use as an opposite case of the original expected result. If the null hypothesis is rejected then that means that our expected result is true. If the null hypothesis is accepted then it means that the expected values are in field of error. When the null hypothesis gets rejected it goes for another series of test a.k.a the LSD (Least Significance Test) but sure that another advance level approach for a hypothesis testing...
