Answer:
A. You remind him that a mutation that increases the expression of a single proto-oncogene is generally not sufficient to cause cells to become cancerous. He should also cause some mutations in the mouse's DNA that cause increased expression of some of the mouse's tumor-suppressor genes.
Explanation:
To begin, mutation can be defined as the changes in genetic composition and/or structure of an organism. Now, we have a scenario a strain of mutant mice is developed in a bid to culture cancer and develop cancerous treatment to the effect. Thus, after causing mutation in a mouse, it is disappointing to know that in spite of this, there's no cancer development.
Hence, it is in the light of this that the scientist need to be reminded that a mutation that increases the expression of a single proto-oncogene is generally not sufficient to cause cells to become cancerous. He should also cause some mutations in the mouse's DNA that cause increased expression of some of the mouse's tumor-suppressor genes.
Option A is therefore the most fitted.
Answer:
so what's the question asking? does she want to know how much? or the necessary items?
a. Transpiration
This process is responsible for loss of water from aerial parts of plants.
b. Photosynthesis
This process is responsible for use of oxygen, water and sunlight to prepare food (glucose).
c. Cellular respiration
This process is involved in breakdown of glucose with help of oxygen, and the end products are CO₂ and energy.
d. Evaporation
It is a simple process related to conversion of water from liquid phase to vapours.
Conclusion
Thus it is concluded from above explanation that cellular respiration is responsible for returning carbon into atmosphere.
