Answer:
The distance between them is changing at the speed of 10.16 m/hr
Explanation:
Consider the sketch attached below.
The question is simply asking to calculate the resultant of the two velocities.
To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.
90 + 45 = 135°
from the cosine rule we have
= 
+ 
- 2abcosθ
= 
+
- 2 ×6×5×cos 135
= 103.426
c = 
c = 10.17 m/hr
The answer is either C because both C and D cause disease, but only C is a living organism. Hope that helps!
Answer: phenotype. An organism's physical appearance, or visible traits. genotype. An organism's genetic makeup, or allele combinations.
No doubt, the United States is a powerful country in the world today. It has made its mark in the history by building a strong economy that every other nation envies, and idolizes as well. But, all that glitters is not gold. And every country has its pluses and minuses. There are some serious social issues in the United States as well that need to be dealt with to maintain the position of power and prestige, and set a true example of ideal society in the world.

The correct answer is B. This question relates to using a punnet square to determine the genotypes of the offspring. Two heterozygous parents expressing a polka-dot tale must have genotype Pp each.
Using a punnet square, this will produce 4 possible genotypes in equal probability:
PP - polka dot
Pp - polka dot
Pp - polka dot
pp - solid tale
Therefore there is a 75% change of getting polka dots in the offspring, and a 25% chance of solid tale.
A. is an incorrect answer because only 50% of offspring will be type Pp, another 25% will be expressing double dominant alleles for P as PP, which will still express polka dots.
