In order to use the Hardy-Weinberg equation to calculate genetic variation in a population which of the following conditions must exist in the population?
All organisms must reproduce.
Why does evolution stop?
Evolution never stops, although at times it is a very slow process. An organism that is perfectly adapted to its ecological niche would experience no evolutionary pressure, but then, no niche stays the same forever; the environment changes, and organisms must adapt.
Why must there be variations in the population in order for natural selection to occur?
Natural selection works via a simple mechanism: certain organisms, though mutation, will be better-equipped for survival than others of their species. Over time, the better-adapted organisms will have a higher survival rate and, through interbreeding and simply outliving the competition, will eventually replace them. If there was no variation (mutation) in the population, there would be no better-adapted individuals, and no change. This has been the case with some species. Alligators, for example, have been around virtually unchanged (except for size) for nearly 100 million years. They are well-adapted adapted for survival in their environment as it is, and thus there is really no need for improvements that would lead to major evolutionary change.
In order to survive all organisms must have?
blood
Identify characteristics that organisms must have to carry on the processes of life?
Organisms must have cells , must reproduce, respond to stimulus and reproduce to carry on the processes of life. They also ought to have energy to perform the various processes.
How are animals adapted to live in the intertidal zone?
Organisms that live in the littoral zone must be adapted to humid, moist conditions. They have to be able to handle dramatic changes in the tides and temperature.
Why must animals high on the food chain eat many organisms at lower levels?
It is important for an organism to belong to a lower trophic level because the lower levels receive more energy for their food. Organisms on the higher levels also rely on all the lower levels.
How organism adapt to their environment?
each organization must assess its own unique situation and then adapt according to the wisdomof its seniour managements
What are 4 things that organisms must keep stable or balanced?
The process of an organism maintaining stability is known as homeostasis. Examples of things that organisms must keep balanced are temperature, pH, the concentrations of ions (such as calcium) and glucose levels.
What must organisms do in a changing environment if they are to survive?
Organisms can cause changes in their environment to ensure survival in various ways. This happens through the various processes that cause organisms in different trophic levels to interact from producers to consumers and to decomposers.
Why would a desert not normally experience fog?
To experience fog an area has to have a relative humidity of near or at 100%. The temperatures must be at or near the dew point. Deserts rarely have the humidity levels needed to produce fog.
Why are matter and engery transferred through an ecosytem?
Energy must be transformed within ecosystems so that it is made available to other organisms. Energy is produced by producing organisms at the lowest trophic level, and then moves up to higher trophic levels to other consuming organisms.
In order to use the Hardy-Weinberg equation to calculate genetic variation in a population which of the following conditions must exist in the population?
All organisms must reproduce.
Organisms that must feed on other organisms for energy are known as?
Consumers ^_^
What is the difference between natural selection adaptation?
NATURAL SELECTION --The process in nature by which, according to Darwin's theory of evolution ,the organisms best adapted to their environment tend to survive and transmit their genetic characteristics in increasing numbers to succeeding generations while those less adapted tend to be eliminated.ADAPTATION--In Biology, the process by which an animal or plant becomes fitted to its environment. It is the result of Natural selection acting on inherited variation. Even simple organisms must be adapted in many ways, including structure, physiology, and genetics; movement or dispersal; means of defense and attack; and reproduction and development. To be useful, adaptations must often occur simultaneously in different parts of the body.
Organisms that below to the same class must belong to what?
Organisms that belong to the same class must also belong to the same phylum. Classes are subdivisions of phyla in the classification hierarchy of organisms.
How many levels down must the commanders intent must be easy to remember and clearly understood?
Counterdrug activities are part of which operational them
