Answer:
The correct answer would be b. the environment.
Due to movement of tectonic plates the organisms would experience different environment. For example, different habitat, different food source et cetera.
As an adaptation to the changing environment different organisms would evolve in different species.
For example, in Galapagos island fiches had developed different sizes and shapes of beaks as a result of adaptation towards different environment.
Explanation:
Leaves have a large surface area so more light hits them. The upper epidermis of the leaf is transparent, allowing light to enter the leaf. The palisade cells contain many chloroplasts which allow light to be converted into energy by the leaf.
Answer:
True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.
Explanation:
- An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
- Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
- Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.
Answer:
Mutations affect evolution by increasing genetic variation and the potential for individuals to differ.
Answer:
<u>No, there is no control group.</u>
Explanation:
To test various theories, experiments are usually conducted under a number of different conditions. Several considerations must be established when planning studies to ensure reproducibility, accuracy, and validity of findings.
For example, while controls are kept constant, or unmanipulated. Also, separate independent variables are strictly altered and analyzed - this guarantees validity and may show whether external influences affected the experiment. Here the variable being altered or measured is the food, and the resultant weight is the factor being observed.
