snow_tiger [21]

Answer:

Cold temperature and higher pH cause the oxygen-hemoglobin saturation curve to shift high reflecting that hemoglobin releases more oxygen.

Explanation:

In higher pH i. e. neutral or alkaline and low body temperature, the hemoglobin molecule attach more oxygen to their active sites. When the temperature of the blood increases, the hemoglobin stops or reduces the binding of oxygen to their active sites and lower the saturation level.    Oxygen-hemoglobin saturation level refers to the amount of oxygen binds with the hemoglobin. This saturation decreases with increase in temperature and lower pH while saturation level increases when the temperature of the body is lower and pH is high.

s2008m [1.1K]
The answer is C) 9:3:3:1

This looks like a dihybrid cross where the expected phenotypic ratio is 9:3:3:1. However, in nature, the numbers cannot be absolut. Let's check it out:
242 purple wrinkled
84 purple smooth
70 yellow wrinkled
24 yellow smooth

Divide all by the smallest number:
242 purple wrinkled / 24
84 purple smooth / 24
70 yellow wrinkled / 24
24 yellow smooth / 24

We have 
10.1 purple wrinkled which is near to 9
3.5 purple smooth which is near to 3
2.9 yellow wrinkled which is near to 3
1 yellow smooth
