This is true.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient exists that allows movement of particles without expending cellular energy.
Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.
Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.
Answer:
True
Explanation:
The lymphatic capillaries have the role to drain extracellular fluid, more precisely the interstitial fluid that surrounds cells. Lymph capillaries process the interstitial fluid, collect it together with the white blood cells and form a lymph. Formed lymph is then transported into a lymphatic vessel, which is connected to a lymph node. Lymph is at the end returned to the venous circulation.
Answer:
So the mnemonic that I know is SNOW DROP. Southern=DNA, Northern=RNA, O=O, and Western=Protein. The question asks, "Which technique CANNOT be used to analyze gene expression?" and the answer is Southern because it is a "techniue used to detect a particular sequence in a sample of DNA."
Answer:
picture? I'll try to answer. It's not B. It's either A, C, or D, but it is <em>most likely</em> not C, So I would honestly say it is probably D
