The normal gradual changes that occur in the types of species that live in an area?

Punctuated equilibrium

1. Evolution did occur. 2. The evolutionary changes were gradual, taking from thousands of years to millions of years. 3. The primary mechanism for evolution was natural selection. 4. The millions of species existing today branched out from a single organism through a process called speciation. 1. Evolution did occur. 2.

there are two different rates that evolution could occur at. the first kind is gradual, which is small changes over time. the other kind is fast and it occurs when there is a big change the environment.

cilia regain normal function

the same thing happens to midgets as it does in normal people only they may not grow taller.

Homeostatic mechanisms are said to act by negative feedback because changes away from the normal state stimulate changes to occur in the opposite direction.

If crossing over didn't occur that could lead nondisconjuction.

The heart has to pump oxygenn aroound the body faster because when you excercise your body is using up oxygen quicker than normal. The pumps get harder and faster.

significant changes occur in the ecosystem

Over time, everything changes. Climates change, species evolve, ecological systems change, and so forth, and a species that was well adapted to a particular ecological niche may eventually find that its niche disappears or changes to the point at which that species is no longer adapted to it.

When no changes in motion occur the forces on an object are balanced.

Every organism changes the environment it lives in. Over time, more and more species can find suitable niches and survive.

Are able to modify habitats more than any other species!

One thing is that scientist think we will lose our pinkie toe

It takes a certain amount of time depending on the creature. You cannot tell how long or how short it can be. It could take a generation or a thousand generations. It all depends on the environment. The traits that species acquire are determined by what the environment selects. If the environment changes rapidly, then the species is going to evolve more quickly to fit the new environment, or in some cases, the environment changes too quickly for the species to evolve in which extinction can occur.

Extinctions are a reaction to changes in the environment. The change can be gradual, like evolution in a predator or prey, or sudden, like a meteor hitting the earth or a massive volcanic eruption, or somewhere in between, like the sudden introduction of an unfamiliar predator species or competing species. So on the rapid side, you have things like human whaling, which is on the verge of driving some species of whale extinct in just a few hundred years (which is really fast in geologic time).

Most of said species die, if there is a favorable mutation existent in the population that characteristic will become more prevalent. If not the species will most likely go extinct.

waht changes in the chromosomes occur during meiosis

Return loss refers to the reflections that occur at changes in impedance.

During menstruation what changes occur in the uterus?

For a new species to form, there must be a long string of mutations and developments based on some environmental need. Eventually enough changes will occur that the organisms that have made the change are no longer recognizable as their original species.

The changes are gradual, but they are not only physical. during puberty, a person's mental status also changes momentarily. they may experience many mood swings and desire sex. they may also want more space and privelages Yes, the brain is adapting to the body changes but not quickly enough in some people. This can make them clumsy and confused. Also it can affect them with dizzy spells when moving around quickly or getting up quick from the chair. A sudden rush of blood to the head.

what are some of the physical changes that occur during adolescence

changes the occur in relationship

There is not a specific time when weather changes occur except for the changing of the seasons.
