The correct answer is - a front.
On this image, the lines are representing a front, and since the signs are marked with blue color, it means that it is a cold front. The fronts are advancing masses of air. In this case, we have a cold front, thus we have advancing cold air masses in the western part of the US, and in the Great Lakes region and the northeastern part of the country. This means that these areas will be affected by colder air masses, that will bring in higher air pressure, colder weather, and cold winds from the direction from which these cold fronts are coming.
Answer:
There are lots of transitional organisms in the fossil record though it does take very specific and precise conditions for a fossil to be preserved, a deer that dies in a field will not end up in the fossil record so we are looking at a small sampling of the evidence (and a good thing too or there wouldn't be anywhere to walk with all the bones laying around)
Explanation:
2 related plants may produce similar substances that could be used for medicines
Mendel observed that a heterozygote offspring can show the same phenotype as the parent homozygote, so he concluded that there were some traits that dominated over other inherited traits. However, the relationship of genotype to phenotype is rarely as simple as the dominant and recessive patterns described by Mendel.
Explanation:
The animals that remain active during the day are called the diurnal while animals that remain active during night are called the nocturnal.
As per the question we can distinguish organisms and plants and see their behavior during the day as well as during night. Diurnal are organisms that activate during the day, while the organisms that activate during the night are called the nocturnal. Among the animals, nocturnal animals are bats, mouse, hedgehog, etc. The appearance of the nocturnal animals is due to the following three factors :
-- to avoid heat
-- to hunt
-- to mate
