Answer:
Survival of the Fittest means that animals best suited to a certain area will survive, not that the largest will survive. An example of this is the mouse.
Explanation:
When an animal adapts to live longer, they are adapting to their predators and their environment. For smaller animals, like mice, being big might mean that hawks are able to find them easier, leaving only the small mice to reproduce. I hope this helps!
Answer:
Physical Pollution
Explanation:
Physical Pollution is the type of pollution which occurs when small particles of soil are suspended in water. The small soil particles do not mix with the water but are rather suspended thus reducing the amount of light energy availed to micro-organisms in the water.
Physical pollution is the type of pollution that is caused by color change, suspended solids, temperature conditions or radioactivity.
Answer:
each of the two daughter DNA molecules contains one strand from the original DNA molecule and one newly synthesized strand.
Explanation:
DNA replication is a semi-conservative process. The two parental DNA strands are separated from each other by the action of helicases. The separated DNA strands serve as the template. Primase enzyme forms primers which are elongated by DNA polymerase enzymes. These enzymes elongate the primer by the addition of deoxynucleotides complementary to the sequence of the template DNA strand.
Therefore, DNA replication forms two DNA double helices from one parental DNA molecule. Each of the daughter DNA molecules contains one parental DNA strand and one newly formed DNA strand making the process semi-conservative.
The correct answers are:
- water;
The water is the essential substance used for the functioning of the living organisms. It is included in the process of photosynthesis, as well as for the bodily functions.
- rocks;
They are the mineral base, thus they provide food source. Also, the rocks are the mother material for the creation of the soils.
- air;
The air has to be just right in order for the organisms to survive. Its composition has to be consisted of elements that are useful for the living organisms.
- sunlight;
The sunlight provides heat, thus it enables the formation of suitable environments, as without it, the Earth would be very old and frozen. It is also crucial for the process of photosynthesis.
