Answer:
Antigens (more info below)
Explanation:
Antigens determine the blood type and may be either proteins or sugar molecule complexes (polysaccharides). Genes in the blood group antigen group provide instructions for the production of antigen proteins. Blood group antigen proteins serve a variety of functions within the red blood cell membrane.
hope I helped!
6.3 ×

In scientific notation, the numerical value without the exponent of 10 must be within the range from 1 to just below 10 (for example, 9.99...). In this case, 6.3 is already within this range, so we just have to multiply it by 1. To get a multiplier of 1 using base 10, we would have to raise 10 to the zeroth power.

Answer:
P = 3.23 atm
Explanation:
Given data:
Number of moles of gas = 30 mol
Temperature = 120°C
Volume of gas = 300 L
Pressure of gas = ?
Solution:
PV = nRT
P= Pressure
V = volume
n = number of moles
R = general gas constant = 0.0821 atm.L/ mol.K
T = temperature in kelvin
Now we will convert the temperature.
120+273.15 = 393.15 K
P × 300 L = 30 mol × 0.0821 atm.L/mol.K × 393.15 K
P = 968.33 atm. L /300 L
P = 3.23 atm
