Light acts like a particle when it bounces off the surface, and acts like a wave when it bends around objects.
Answer: A. Does the wave require a medium to travel.
Explanation:
Mechanical waves require the presence of a material object to be able to engage in energy transfer. For example, Sound is a mechanical wave that needs a medium to travel such as a solid or liquid.
Electromagnetic waves on the other hand, are able to travel through a Vacuum including that of space and they include all light waves. This is why the sun's light is capable of reaching Earth.
Answer:
A
B
D
Explanation:
The Digestive System, the Immune System and the Reproductive System have common functions because they all do the same thing. They all digest food but in their different ways
The chance that the child produced would have nail-patella syndrome from this mating is 1/8 (12.5%) and the chance that the child has alkaptonuria is zero (0%). It is a case of recessive phenotypes.
<h3>Pedigree and genetic inheritance</h3>
The answer is incomplete, but I have now included the Figure to answer it. The vertical lines indicate nail-patella syndrome, while horizontal lines indicate alkaptonuria.
Pedigree is a diagram showing the genealogical relationships in different individuals, which is usually used to represent the inheritance pattern of a given phenotype.
In this case, the nail-patella syndrome and alkaptonuria are recessive phenotypes, which means that individuals may be heterozygous carriers but they need to have both mutated alleles to express each condition.
In the pedigree, it is possible to observe that the individual IV5 expresses both syndromes (nail-patella syndrome and alkaptonuria), whereas there is a 1/8 chance that the individual IV2 is a carrier of the nail-patella syndrome.
