Answer:
From the given information, the transport of glucose in blood across the red blood cells takes place by facilitated diffusion, that involves the spontaneous passive-transport with the help of trans-membrane proteins or transporter proteins to move the ions or molecules down the concentration gradient.
While the transport of glucose in intestines take place via active transport mechanism. It takes place from gut into intestines. It occurs against the concentration gradient with the help of energy molecules like proteins.
The correct answer is: a. the agar and air in the petri dish are providing all of the resources needed by the bacteria.
There are four phases of bacterial growth:
1. Lag phase-bacteria prepare for reproduction
2. Log phase- cell doubling
3. Stationary phase- due to a growth-limiting factor
4. Death phase.
Answer:
option A
Explanation:
The protein specific sequence also known as the primary sequence is determined by the sequence of its amino acids linked together by peptide bonds. The sequences of amino acids determine the proteins that will eventually be synthesized. This proteins becomes functional when correct folding pattern/ native conformation of the protein occurs which determines the shape of the proteins. peptide bonds hold the amino acid sequences together, hydrogen bonds involving components of the peptide bonds allow for the existence of the secondary structure either the alpha helix or the beta pleated sheets and then disulphide bonds and other type of bonds helps in the folding of the protein to become a functional protein.
Answer:
all functions
Explanation:
To survive, unicellular cells must carry out all functions.
