When there is a natural selection upon any species this means that that specific species has an adaptation / a increase in survival skills .
There a Giraffes for EXAMPLE : one group of giraffes have medium length necks and the 2nd group has longer necks , so they can reach the 85 foot tall trees.
That was an example of natural selection , i hoped that my answer helped yo out a lot , have a nice day.
For natural selection to occur, several premises must be satisfied. Firstly, there must be variation in a population. If all individuals are the same, there is no variation on which selection can occur. Secondly, these traits must be heritable, meaning they are passed from parent to offspring. Natural selection cannot operate on traits that have no genetic basis. There must also be differential reproduction, which means that some individuals must reproduce more than others. When all of these factors occur, natural selection results in evolution as advantageous traits propagate throughout the population.
Natural selection is quite variable, as changes in the environment impact what traits are advantageous in a particular time and place. A good of example of this comes from Galapagos finches. These birds have varying beak sizes. Wide beaks are best for eating hard seeds, while long narrow beaks are more adept at exploiting the fleshy fruit from trees. Typically narrow beaks are more prevalent, but during drought conditions when trees cannot produce fruit, seeds become a more abundant food item. This results in those finches with wide beaks having more food available and reproducing more than those with narrow beaks. When droughts persist over many years, wide beaks replace narrow beaks as the most common, but this trend reverses when droughts end and fruits once again become available.
The Calvin cycle begins a incorporation of carbon dioxide from the air to organic molecules already present in the chloroplast (known as carbon fixation) chemical energy is supplied by atp and nadph provides electrons
A student constructs a Venn diagram to compare the organelles in plant and animal cells. Venn Diagram of Plant and Animal Cells A Venn Diagram is shown. One circle is labeled Animal only, the other circle is labeled plant only, and the overlapping section is labeled both. Which organelle should be listed under “Animal Only” in the diagram? nucleus centriole ribosome cell wall"
The reason as to why the breaks of a vehicle becomes hot
when they are continuously used is because of the fact that the kinetic energy that
is being used is being converted to a thermal energy, causing the brakes of the
vehicle to be hot.
The mass of an object is a measure of the object's inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it. The pull of gravity on the earth gives an object a downward acceleration of about 9.8 m/s2.
