What best describes diversity in terms of natural selection?
Diversity is the number of different role players (species) in an area. I like to think of diversity in the form of niches. The number of niches being filled in an ecosystem is directly related to the diversity.
What happens when the water table is above the surface at various places?
If the water table is higher the the surface of the land, water will seep out of the land surface and form a puddle, pool or lake. The depth of the water body will increase until the water surface is at the same level as the surrounding water table - this is a state of equilibrium. If the water table lowers, so will the water level in the water body, until equilibrium is reached. Water moves slowly into and out of the land surface and follows the movement of the water table in the area. Don't confuse this with storage reservoirs behind dams. These have an artificially high water level and the surrounding water table can be lower than the reservoir.
How is genetic diversity important to the concept of natural selection?
Without genetic diversity, natural selection cannot occur
Why does air flow from water to land during the day?
The sun more quickly heats the surface of the land during the daytime than that of the water. The reason for this is that the surface of the water has a much higher effective heat capacity (amount of temperature change for a given unit of heat imparted) than land. This contrast in surface temperatures causes the air column over land to expand, consequently an upper level pressure gradient to develop (high over land at altitude vs low over the water) and flow at altitude from land to ocean. This movement of air out of the land air column and towards the water air column causes a surface pressure gradient to develop, with a surface level high pressure over water and a surface level low over the land. This gradient drives the daytime "see breeze" flow of surface level air from the water to the land. It's actually part of a cell that develops that can be thought of as a roll laying parallel to the shore, going up over land, out to sea at height, down over the sea, and towards land at the surface.
Shallowest zone of the benthic environment?
The question is slightly incorrectly phrased as the benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers.
What is the surface-level of a movie?
What is the surface-level subject in a film?
What is deep level diversity?
Deep level diversity is wherein individuals feel they diverge from members of a work group. This is the degree to which individuals differ in personality, values or attitudes.
A flat level surface?
A flat, level surface is a plane.
Which level of biodiversity may still be reduced after a species recovers from a threat to its survival?
species diversity
What level of classification was developed because of prokaryote diversity?
Domain
What is a level a tool which shows if an object has an even horizontal surface?
A level is a tool that is placed on a solid surface. There is a string hanging on the level, and if it tilts, the surface isn't an even horizontal surface. If the string doesn't tilt, the surface is even.
What level of classification developed because of prokaryote diversity?
Domain
Why do monera live everywhere?
Their nutritinal diversity,diversity of respiration,high surface-volume ratio,High metabolic rate,being very small,high reproducing rate
What is diversity in an ecosystem?
the types of plants and animals that are located in that ecosystem
Does oceans have diversity why or why not?
Yes, It has a wide variety of life. Over 70% of the earth's surface contains water, so there is a heck of a lot of room for life. However, Human activity has threatened this diversity.
4 letter word for flat level surface?
even ? when something is flat and level it is often referred to as an even surface.
