Options:
- a lake
- a prairie
- the land an organic farmer uses to raise crops to feed his dairy cattle
- a large island in the tropics that has snowcapped mountains
Answer:
a large island in the tropics that has snowcapped mountains
Explanation:
The land a farmer uses is likely to be quite highly regulated in order to ensure that his dairy cattle thrive. That means the growth of certain plants will be controlled, and this will likely impact diversity.
A lake and a prairie could have diverse and balanced ecosystems. However, due to the limited habitat are likely only to harbour specific organisms. E.g. the lake will only harbor organisms that thrive in water environments.
A large island will, first of all, have a lot of space to support diversity. It is in the tropics, meaning it will have species suited to a hot and wet environment. Since it is an island, there will also be the involvement of sea/ocean dwelling creatures. However, there is also mountainous habitat that has snow, meaning it is high up and cold. This provides a habitat for even more species adapted to different environments.
Therefore, the island will be the most diverse.

<h2>Answer is option "C"</h2>
Explanation:
- To clone a plant means to create an identical copy of an adult plant. These identical copies become young plants that in turn become adult plants that can be cloned again. This process can go on indefinitely
- The most common method of cloning plants and the one that has been used for a very long time is that of taking cuttings from an adult plant. A cutting is a stem or leaf that is cut from an adult plant. The cutting is then planted into moist soil or other moist growing media. The cutting will produce roots of its own and then become a whole new plant identical to the original adult plant. Not all plants can be cloned via cuttings, though
- Vegetative proliferation works in light of the fact that the finish of the cutting structures a mass of non-particular cells called a callus. With karma, the callus will develop, gap and structure different specific cells (roots, and so on.), in the end framing another plant
- Hence, the right answer is option C "Clone the plant"
Answer:
Because of the several steps with high temperatures and also (heavy ) changes in temperature.
Explanation:
PCR consists of a serie of 20–40 repeated temperature changes. Those series or cycles are also called thermal cycles.
The individual steps (common to most PCR methods) are as following:
→Denature template : 99 °C for 2 minutes
→Anneal primers to template : 55 °C for 2 minutes
→Extension of the primers by heat stable DNA polymerase :72 °C for 2 minutes
As we can notice, will in a relatively short time, different temperatures be used. It's important that the used polymerase will be functional at corresponding temperatures, as well as (heavy) temperature changes.
→ Since the bacteria Thermus aquaticus lives near thermal vents in the ocean floor and grows at temperatures of up to 98°C, it's used to corresponding temperatures.
If other enzymes will be used, i.e enzymes functional in lower temperatures (several) steps will not continue or will not be executed properly. To avoid this it's important to use the best temperature resistant enzymes.
The answer is C because you want to focus on what will happen with/without sunlight and the growth of the plant.
