Answer:
Explanation:
Refraction, on the other hand, bends the waves as they go through one medium to another medium, or change their direction. The amount or degree of the bend would depend on the medium they go through. If the mediums are different, it would substantially change the wave's path. The reason for this is because the medium changes the speed of the waves that go through them, depending on the material they are made up of.
A classic example of this would be the straw in a glass of water.
Diffraction occurs when the waves go through an opening of the medium or barrier. If the opening is smaller than the wave that passes through it, it would spread out wider, coming out of the opening, but if it is bigger, then the spread would decrease.
In x-ray crystallography, they use this by letting x-rays pass through the spaces in between the crystals

Why do some people require bifocals (or even trifocals) as they age?
Answer:
Explanation:
People have to wear bifocals most commonly because of a condition called presbyopia. This condition occurs naturally. It causes difficulties in the eye’s focusing abilities. Bifocals work to help the eyes focus more clearly, which is why people have to get them.

Genes A, B , C and D are present on the same chromosome. The recombination frequency between the genes is as follows: A and B: 24%, A and D: 16%, B and C: 18%, C and D: 10%. What is the correct order of genes along the chromosome
Answer:
BDCA
Explanation:
Recombination, also know as crossing-over, refers to the exchange of genetic material (DNA) between non-sister chromatids of homologous chromosomes during cell division (meiosis). The recombination frequency refers to the frequency of crossover between two genes/loci during meiosis. The recombination frequency is not a direct result of the physical distance between genes/loci on the same chromosome, but this value provides a good approximation of such distance. The recombination frequency is measured in centimorgans (cM), where 1 cM is equal to a 1% chance of recombination. The higher the recombination frequency between two genes/loci, the greater the chance that a cross-over will occur between them, and the greater the distance between them. Moreover, the lower the recombination frequency between two genes/loci, the lower the probability that they will separate by recombination, and the more closely they are linked.

On the planet Fugus, there is a species of flowers, Dontdrinkmycola, that has two special loci: Bach01 and Bach02. At Bach01, there are two alleles in the population: A (dominant) and a (recessive). Similarly, at locus Bach02, there are two alleles in the population: B (dominant) and b (recessive).
Individuals with the A_ genotype at Bach01 have mauve colored petals, and individuals with the aa genotype have teal colored petals. Likewise, individuals with the B_ genotype at Bach02 have mauve colored petals, and individuals with the bb genotype have teal colored petals.
In a cross between two doubly heterozygous Dontdrinkmycola flowers, the following number of offspring are produced: 280 offspring with mauve colored petals, and 220 teal-colored petals. The most likely form of epistasis here is:
a. Duplicate dominant epistasis.
b. Dominant recessive epistasis.
c. Duplicate recessive epistasis.
d. Recessive epistasis.

Most of the coal found on Earth today was formed during the Carboniferous and Permian Periods. About how old could a piece of coal be?
Answer: 298.9 million years old
Explanation: hope it helps luv ❤✨
A piece of coal would be 298.9 million years old. This is because the Permian period was initiated approximately 298.9 million years ago.
What are the characteristics of coal?The characteristics of coal are as follows:
It primarily consists of carbon, hydrogen, and oxygen.It contains a very less amount of sulfur and nitrogen.It is black in color and has a metallic luster.It is significantly hard as stone. Coal is widely utilized in power plants in order to generate electricity.According to ancient tomes and periods, the Permian period ends about 252.2 million years ago and it was the time of the initiation of the carboniferous period that further extends to the Triassic period. This was all about the time duration when the first piece of coal was found in the atmosphere.
Therefore, a piece of coal would be 298.9 million years old.

What is some evidence that makes plate tectonics is such a firmly believed idea?
Answer:
There are many shreds of evidence that support the theory of plate tectonics and make it such a firmly believed idea. These pieces of evidence include fossils, glaciers, earthquakes and volcanic activity, the shape of continents, the magnetism of rocks on the seafloor, the mid-ocean ridge system, and others.
Fossils give an idea of the location of the plants and animals that once existed. Earthquakes and volcanic activity also help in determining the cause of the boundaries and rifts formed. The shape of the continents seems to be fit with one other that gives the idea that these were together and moved away from each other.
. One function of the circulatory system is to help maintain a uniform body temperature. Explain how the constant circulation of blood through the body can accomplish this.
Answer:
Capillaries are the blood vessels with the smallest diameter and those closest to the surface of the skin. The blood that circulates through them is therefore closer to the outside air than the blood in the rest of our blood vessels. As the capillary dilates, a greater amount of blood is exposed to the air, which allows it to cool down and our body temperature to be maintained.
Explanation:
Blood is a solution where solutes and cells are found and that participates in homeostatic mechanisms such as the control of body temperature, helping to regulate respectively the preservation and elimination of heat. Blood vessels are the routes of the cardiovascular system, which are responsible for being a means of transport for blood with and without oxygen that reaches all tissues and returns to the heart. In very hot weather, surface thermoreceptors signal the brain that something needs to be done to dissipate heat. For this reason, a vasodilation process is activated, which allows blood to flow to the outermost layers of the skin. This promotes a heat exchange with the environment, which helps the individual to lower their body temperature. Cold causes a decrease in blood flow by reducing the size of the vessel (arteries or veins) through which blood and other substances circulate. By reducing the size of the vessel, the substances that circulate in the blood are also reduced. The heat causes an increase in the size of the blood vessels, which generates greater transport of nutrients through the blood.
