Answer:

Density independent factors refer to any influences on a population's birth or death rates, regardless of the population density. Whereas, Density dependent factors affect a population through increasing or decreasing birth and death rates.

Density-dependent regulation can be affected by factors that affect birth and death rates such as competition and predation.

How many rounds of replication does it take for an incorporation error to be established as a base pair change?

iris [78.8K]

Answer:

Just one round without DNA repair

Explanation:

When an error occurs before or during replication, in a normal system, there is always proofreading and correction. If the error is not corrected during replication, it can then be corrected by the DNA damage repair system. But if not also corrected, the error becomes fixed and subsequent replication will produce this error

vitfil [10]

Answer:

The correct answer is -

Decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

NO effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

Increase plant growth - increase CO2, increase sunlight, increase H2O

Explanation:

Decrease in exposure of sunlight to the plant or less intense light will affect the production of oxygen and glucose negatively which affect the growth of the plant. Decrease CO2 will be affect the growth of the plant similarly as light and water molecules which is decreased in plant growth.

Increase in the in production of the products which are 02, glucose, will have no effect in plant growth though increase in the carbon dioxide, water, and sunlight will positively affect plant growth.

Thus, the correct answer is - decrease plant growth - decrease sunlight, decrease CO2, decrease H2O

no effect - increase O2, decrease O2, increase C6H12O6, decrease C6H12O6

increase plant growth - increase CO2, increase sunlight, increase H2O
