If the distance between the source of light and the plant is increased, the rate of photosynthesis will decrease.
Answer:
D - Its genetic diversity is very low
Explanation:
An extinction vortex can be defined as the process which populations in decline pass through to drive them into a vortex of smaller populations, endangering their survival as they tread the path to extinction.
Populations that fall to extinction vortex already have small populations which is usually as a result of certain powerful genetic factors, which cause the populations to continue to decline in size.
During genetic drift which occurs in all populations, small populations tend to lose genetic diversity as a result of the random nature of gamete sampling.
This is because any change in alleles in a small populations can have dastardly effects on the populations size due to a small gene pool.
Answer:
-
Periods of light-time
- Temperature
- Substrate/Soil type
Explanation:
Controlled variable: Variables that are controlled and have no influence on the results of the experiment. These variables do not affect the change in the dependent variable values.
These variables must be the same for all the subjects or groups (control and experimental). In the case of plants, controlled variables are probably those needed by the plants to correct development.
All plants should be exposed to the same period of light-time and the same temperature. Also, the substrate or soil where the plants are growing should be the same.
Both of the above because they belong to the same principle. I hope this helps!
