Answer:
Geographic isolation
Explanation:
Geographic isolation is a term that refers to a population of animals,plants and other organisms that are separated from exchanging genetic materials with other organisms of the same species. This usually occur as a result of accident or coincidence.
Liocleonus clathratus usually referred to as L. Clathratus is a species of cylindrical weevils that belongs to the curculionidae family . It can reach a length of 1cm.The body is elongated and the basic coloration is white, with
longitudinal black markings on the pronotum and elytrae.
When a Plateau is been divided into a valley as a result of natural factors such as earthquake or erossion, plants and organisms are been isolated or separated from their mass habitation. This right here is coincidental and a natural accident .
The ability to reproduce species of their kind will be limited since they are not able to exchange genetic materials with other organisms of same species as each one will be displaced into different location.
Answer:
B. Look around, since even a changed ecosystem is still an ecosystem.
Explanation:
Ecosystem refers to the interaction or relationship that exist between living organisms and its surrounding environment. This environment provides habitat, food and other needs to the organisms. If the people in the Midwest determine what kind of natural ecosystem they are in, they have to look around the environment they are living. This environment includes all the plants and animals that survive the change which occurs due to humans intervention.
The topography of Bangladesh is frequently altered due to floods.
<u>Explanation</u>:
- Even though Bangladesh is a small country, it has considerable topographic diversity.
- It has three prominent features - a large alluvial plain subject to frequent flooding, a slightly elevated relatively older plain and a small hill region drained by flashy rivers.
- Bangladesh experiences heavy monsoon rains, especially over the highlands.
- Causes of flooding in Bangladesh include -
i. monsoon climate which brings heavy rains.
ii. spring snow-melt which results in soil erosion and a rapid increase in river discharge.
ii. deforestation in head water areas due to increasing population in Nepal and Tibet.
iv. rivers slit-up due to increased soil erosion which raises river beds and lowers the capacity of the channel resulting in floods.
The idea of time zones is to have a particular time of day have the same meaning worldwide. For example, noon will be the point in time when the sun is the highest, if you compare from exactly on one line of a longitude line that is used to determine the time zone (actual time zone lines change based on settlements and politics, so use the longitude line it is based on).
<span>The sun rises and sets based on the earth's rotation on its axis. Time zones divide the earth into 24 areas that will be rotated into. Latitude lines have nothing to do with the time of day or the earth's rotation--they tell you where something is north and south rather than east and west.</span>
