The answer is C. Fast moving water, due to steep slopes in
the mountain form V-shaped valley because
the erosive power of the water is
projected vertically more than horizontally. This is the vice versa in plains
where the water moves at slower speeds. The horizontal
erosion power is dominant over vertical erosion
hence the banks of the river are eroded more than the bed in the plains.
Answer:
Daughter cells receive one set of the original strands of DNA of a parent cell and one set newly synthesized during the events of cell division.
Explanation:
Hey there!
For this problem, I would take a look at which answers you can get rid of based on the situation and some common sense:
<span>
<span>A. comparing the cost of raking the lawn, three hours, with the benefit of raking the lawn, $10: </span>This one seems to make the most sense to me, given the situation. Even though she may have the tools to rake the lawn, you would also have to count the time that it would take to complete the task, since it would still be using up a resource. Cost–benefits analysis looks at a lot of aspects, such as money, time, risks, imperfections, uncertainties, etc.
</span>
B. <span>comparing the cost of raking the lawn, $0, with the benefit of raking the lawn, $10: This doesn't apply given the information in my last point, since cost–benefit analysis looks at more than just money.
C. </span><span>comparing the benefit of raking the lawn, $10, with the benefit of not raking the lawn, $0: This one doesn't have a cost, and earning no money for not doing something doesn't sound like a benefit to me.
D. </span><span>comparing the cost of raking the lawn, three hours, with the cost of not raking the lawn, no hours: This one just doesn't make sense to me. Spending no hours doing something isn't a cost. Again, it's missing half of the equation, which is the benefit this time.
I would say your answer is A.
Hope this helped you out! :-)</span>
Animals memories are very good especially Dolphins. Dolphins Have Longest Memories in Animal Kingdom. Marine mammals can remember their friends after 20 years apart, study says. Bottlenose dolphins (pictured in the Caribbean) have amazing memories, a new study says. Sorry, elephants: Dolphins have taken the top spot for best memory, at least for now.Aug 6, 2013
Answer:
It allow organisms to pass down their traits to the next generation.
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Natural selection can be defined as a biological process in which species of living organisms having certain traits that enable them to adapt to environmental factors such as predators, competition for food, climate change, sex mates, etc., tend to survive and reproduce, as well as passing on their genes to subsequent generations.
Simply stated, natural selection entails the survival of the fittest.
Artificial selection is also known as selective breeding and it is a process that involves humans (breeders) selecting the animal or plant with desirable traits in order to reproduce favorable offspring having phenotypic traits.
Hence, the role which reproduction play in both natural and artificial selection is that it allow organisms to pass down their traits to the next generation.
