The answer is an overhunting.
<span>The bottleneck event means drastic reduction of the population size because of environment changes. The consequence of this is the reduction of genetic variation. The bison population is a good example of the population bottleneck. The bison population drastically reduced its size due to overhunting which culminated at the end of the 19th century, when bisons almost extinct. </span>
The most likely consequence of the widespread lack of bees is loss or reduction of food. Majority of food depends on pollination and bees are major pollinators in the ecosystem, playing an essential role in food production among different type of plants. Bee’s declining population is mostly associated to excessive use of pesticides or toxicants in industrial agriculture as well as presence of different parasites or pathogens and even climate change.
B Since protons and electrons have to be the same amount!
The type of mutation that will eventually occur is A TO G BASE SUBSTITUTION.
In this type of mutation, what will happen is that, in all the points where adenine base is suppose to be inserted, it is the guanine base that will be inserted there. This is an example of base substitution error in DNA replication.
<h3><u>Answer;</u></h3>
primary ecological succession
A glacier retreats exposing bare rock and allowing communities of organisms such as moss and lichens to move in. This is an example of <u>primary ecological succession.</u>
<h3><u>Explanation</u>;</h3>
- Primary succession is a type of succession that occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine.
- <em><u>Primary succession occurs in lifeless area; that is regions in which soil is incapable of sustaining life.</u></em>
- <em><u>The first organisms to appear in areas of primary succession are often mosses or lichens, often known as pioneer species because they are the first species present.</u></em>
