Answer:
It is better to compare the average height gain of control and experimental groups of plants to eliminate all other variables.
Explanation:
If you evaluate individual plants, the data may vary. The experimental group is the one where an experimental procedure is performed while the control group does not receive any treatment.
The removal of insects would mess up the food chain. Many animals rely on insects as a source of food and energy. Eventually everything would die off.
Gene—>DNA—>Chromosome
Gene: a section of DNA
Chromosome: combination of sections of DNA
First you need to determine how much standard deviation the range is.
120+12*x= 96
x= 96-120/ 12= -2
120+12*y=144
y= 144-120/12= +2
Systolic blood pressure between 96 mmHg and 144 mmHg means that the blood pressure is at -2SD to +2SD. The Z-score for -2SD is 0.0228 and +2SD is 0.9772
So the percentage would be: 0.9772- 0.0228 * 100%= 95.44%
<span>The question says, which of the following is not required by an animal to control body temperature. All these statements are true except D. The correct option is D. The fat in animals bodies keep them warm at all times and animals do not have to look for a source of heat to keep warm. They are able to regulate their body temperature internally. </span>
