b. The A chain binds to clathrin. The B chain interacts with SNARES
c. The A chain stimulates autophagy
d. The protein enters through pore complexes in the plasma membrane.
The correct option is a
The protein is internalized by endocytosis.
Explanation:
The protein is internalized by endocytosis because Ricin is a potent toxin gotten from lecithin. It internalised in the intracellular cell by endocytosis or substances are brought inside the cell and translocated into the cystosol which hereby inhibit protein synthesis and kill the internal cells. These internal toxins are transported to lysosomes for degradation
The expression would be $0.20 x f. Once you figure out what the 'f' variable stands for, you have to multiply it by $0.20, and you will have your answer.
Autumnal equinox right ascension = 12 hours; declination = 0°; Sun rises at 90° azimuth and sets at 270° azimuth. December solstice right ascension = 18 hours; declination = -23.5° Sun rises at greater than 90° azimuth and sets at less than 270° azimuth.
Balanced chemical equations only show formulae, not names. A balancing number, written in normal script, multiplies all the atoms in the substance next to it.
