Species evolve independently possibly due to geographical isolations or behavioural isolations.
Geographical isolation includes the isolation of 2 groups of the same species. Since these 2 groups live in different locations, (e.g. a volcanic eruption resulting in a barrier between one side of an ocean and another side of the ocean), they will have different selection pressures in their different environments as well (e.g. one side of the ocean may have more sunlight and thus more underwater plantations than the other side of the ocean). Natural selection will eliminate those with disadvantageous characteristics (e.g. Fishes that only eat plants and nothing else on the side of the ocean with little plantations) with unfavourable alleles, and select for those with advantageous characteristics (e.g. Fishes are able to eat plants and other organic substances as well on the side of the ocean with little plantations) with favourable alleles.
Since the 2 groups have different selection pressures, natural selection will occur in different ways, selecting for and against different types of fishes with different types of alleles. Also, because of the barrier, they are not able to mate with each other, and there are no mixing of genes from one side of the ocean and the other side. They are genetically isolated. As genetic drift occurs over time, their gene pools become different from each other. Thus, they evolve independently.
Hope this helps! :)
Answer:
<h3>Recently been reviewed and range from single cell protein </h3>
Explanation:
I hope it is correct
Answer:
alright bet I got this
Explanation:
Have you ever wondered what can happen to those plastic bottles you toss away? How do they decompose? What happens to them? Its simple really, they get eaten! No, not by people of course they are eaten by a tiny critter called a wax worm. The wax worms earn their name because they are often found living in beehives where they eat the beeswax.
Wax worms much like mealworms are used to break down things that would normally be endangering to our environment. These seemingly useless little animals do a whole lot for our environment especially with the amount of waste we produce! They really are a tiny secret hero to todays pollution problem.
After quite a few studies scientists are still unsure on how was worms can breakdown plastic with their tiny bodies but they appreciate the work these little recyclers do. They have a lot of theories on how these worms do this one of the theories is that bacteria can break it down, another theory is that enzymes in the worms intestines break down plastics. Though scientists believe it will take a while to figure this out they enjoy studying and learning more about this tiny helper.
Answer:Stars are formed in clouds of gas and dust, known as nebulae. Nuclear reactions at the centre (or core) of stars provides enough energy to make them shine brightly for many years. The exact lifetime of a star depends very much on its size.
Answer:The seminal vesicles produce mucus to neutralize the acidic environment of the vagina.
Explanation:
The seminal vesicles is found in male reproductive system which produces mucus that is alkaline in order to protect the sperm from the acidic environment of the female vagina . This also contain sugar to nourish the sperm.
The vargina is the outer opening of female reproductive system that receives the sperm. It is acidic in nature because it discharge fluids that contain liquid, cells and bacteria that lubricate and protect it.
