Answer:
According to Darwin's theory of evolution, new species evolved as a result of natural selection.
Explanation:
- Darwin proposed that speciation could readily occur through the prolonged action of Natural selection.
- Natural selection allows the 'survival of the fittest' i.e. a more fit organism will have a better chance of survival than the less fit one.
- The result of Natural selection could be positive,negative or balancing.
- Evolutionary process in which the genetic changes confer a higher fitness to increase frequency of the organism over time in population is called positive selection.
- Evolutionary process in which genetic changes decreases the organism's fitness resulting in its disappearance from the population is called Negative selection.
- It may happen that a mutation benefits hetero-zygotes but not homo-zygotes and alleles maintain a intermediate frequency in population.This evolutionary process is called balancing selection.
Answer:
Well there are many ways for scientific models to be use like if something was small and you couldn't see it u would have to make a model of that
Explanation:
If this didn't help I'm sorry
<u>Answer:</u>
Heat moves from the land to the air through the process of "conduction".
<u>Explanation:</u>
When the two things come in contact with one another at different temperatures or basically when heat flows from the warmer to the colder region or phase until both reach at the same temperature is understood as "conduction". Conduction is a physical process which occur by collision of the microscopically colliding particles like molecules, atoms and electrons on the movement of heat through a substance.
While convection take place by the movement of heated objects and it isn't the process influencing air and water temperature difference. The examples of conduction are like a radiator, a heating pad, sand can conduct heat etc.
This is false.
These are called perennial plants. Annual plants go through their entire life process within a single year and stop existing, meaning they can't produce fruit every year.
