Answer:
<h2>Both Yy</h2>
Explanation:
1. As given here,
Total offspring are= 124;
that produce yellow squash= 93;
that produce green squash= 31;
2. Let Y for yellow producing squash and y for green squash;
Y is dominant over y.
3. Cross between two yellow squash producing plants
Genotype of parents = Yy and Yy
offspring = YY, Yy, Yy and yy,
as Y is dominant over y, so YY and Yy all produce yellow squash, and yy produce green squash.
4. Their phenotypic ratio is 3:1 , as in question 93: 31
Answer:
Without naturally occurring greenhouse gases, Earth's average temperaturewould be near 0°F (or-18°C) instead of the much warmer 59°F (15°C). The concentration of greenhouse gases, especially carbon dioxide and methane, has fluctuated naturallyover geological time scales.
Answer:
Effects of exercise on breathing
During exercise there is an increase in physical activity and muscle cells respire more than they do when the body is at rest.

The heart rate increases during exercise. The rate and depth of breathing increases - this makes sure that more oxygen is absorbed into the blood, and more carbon dioxide is removed from it.
The rate of breathing can be measured by counting the number of breaths in one minute. The depth of breathing can be measured using a spirometer (a device that measures the volume of air inhaled and exhaled).
To investigate the effects of exercise on breathing, record the rate of breathing for a few minutes when the person is at rest. After they do some exercise, record their rate of breathing every minute until it returns to the normal resting value.
