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.

The answer is A: Between 50 and 5,000 amino acids
Answer:
2.6 kJ
Explanation:
The formula for the amount of heat (q) absorbed by the water is
q = mCΔT
1. Calculate ΔT
ΔT = 23.5 °C - 22.1 °C = 1.4 °C
2. Calculate q
q₂ = mCΔT = 500 g × 4.184 J·°C⁻¹g⁻¹ × 1.4 °C = 2900 J = 2.9 kJ
Answer:
The answer to your question is 1.40 moles of N₂O
Explanation:
Balanced equation
NH₄NO₃ ⇒ N₂O + 2 H₂O
2 -------- N ---------- 2
4 ------- H ---------- 4
3 ------- O ---------- 3
Process
1.- From the balanced equation, we know that 1 mol of NH₄NO₃ produces 1 mol of N₂O so, we use proportions to find the number of moles produced when 1.40 moles of NH₄NO₃ react.
1 mol of NH₄NO₃ ------------- 1 mol of N₂O
1.40 moles -------------- x
x = (1.40 x 1) / 1
x = 1.40 moles of N₂O are produced
Answer:
The limiting reactant is propene, 
.
Explanation:
Moles of nitrogen propene = 2 mol
Moles of oxygen = 10 mol
According to reaction, 2 moles of propene reacts with 9 moles of oxygen gas, then 2 moles of propene will react with:
According to the question, we have 10 moles of oxygen gas, which is more than 9 moles of oxygen gas. This indicates that propene is present in a limiting amount hence, it is a limiting reactant.
The limiting reactant is propene, hence the correct answer is the .
