Answer 1

Step-by-step explanation:

It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.

Answer 2

Answer:

Let the age of A be a, and age of B be b

Now, a−5=3(b−5)

a=3b−10 (1)

After 10 years,

a+10=2(b+10)

a=2b+10 (2)

From 1 and 2,

3b−10=2b+10

b=20

And, a=2b+10=2×20+10=50 years

Thus, age of A = 50 years and age of B = 20 years.
