A plant reaches its adult stage
when it is ready to reproduce.
The statement “All plants
reproduce several times before dying” is true. The answer is letter A. Plants
can reproduce several times as long as it has the gametes needed for
reproduction.
Answer:
The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).
Explanation:
There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.
The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.
For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
- <em>Other options, such as </em><u><em>an increase in food availability</em></u><em>, a</em><u><em> decrease in tuna fishing
</em></u><em> or </em><u><em>a decrease in tuna predators</em></u><em>, are environmental factors that contribute to increased genetic variability.</em>
This statement is true. Developing countries indeed tend to have more people in urban areas than rural areas. For example, New York City has the massive population in the state of New York, compared to its rural areas upstate.
