I believe it's B. Plasma and red blood cells are the 2 main components of blood.
Answer:
Relationship Between Diameter and Circumference
If you know a circle's diameter, you can calculate its circumference with this equation: Circumference = diameter times pi (3.14).
Answer:
0.949367 ≈ 0.95.
Explanation:
The chi square analysis can be done by the formula as follows:
Chi square = (O-E)²/E
Here, O is observed value and E is expected value.
The tall trait follows the Mendel's law, this means the cross between F1 results in the formation of progeny with ratio 3( tall) : 1 (short).
The observed values for set I is 63 tall, 16 short.
The expected value for tall plant =
= 59.25 .
The expected value for short plant =
= 19.75.
Put these value in the formula for chi square analysis:
For tall plants = ( 63 - 59.25)²/ 59.25= 0.237.
For short plants = (16 - 19.75)²/ 19.75 = 0.712
Total value for set I = 0.237 + 0.712 = 0.95.
Thus, the answer is 0.95.
Answer:
this is just evolution like the birds on the Galapagos islands also I don't see the question
