If you change two of the three variables than you don’t know if the change is caused by variable A or variable B. In this case if you keep light constant but change the amount of co2 and the color of the light, you can’t which of these two are affecting photosynthesis.
Somatic mutations are acquired after birth in non-reproductive cells. These changes occur in only certain cells of the body and can be caused by tobacco use, ultraviolet radiation, viruses, chemicals and age. Acquired mutations are the most common cause of cancer.
Humans experience many somatic mutations over a lifetime, and the human body is normally able to correct most of these changes. This is why there is only a small chance of one mutation causing cancer. It normally takes many mutations over a lifetime to cause cancer. This is why older people are the most likely group to get cancer, as they have had more chances for mutations to build up.

Explanation:
The individual organisms that frame a population are additional or less equally spaced, spread every which way with no predictable pattern, or clustered in teams. These are called the uniform, random, and clumped dispersion patterns. Uniform refers to the evenly distributed population, random means random spacing and clumped shows the distribution in clusters.
Food supply and resources are directly proportional to a particular distribution pattern. Random distribution occurs when several pollen grains of some flowers were carried by wind or bees. These flowers will then bloom where they were scattered.
hope this um ... helps hehe ........
Answer:
Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
