Speed = (256 Hz) x (1.3 m) = 332.8 meters per second
2). If the instrument is played louder, the amplitude of the waves increases.
On the oscilloscope, they would appear larger from top to bottom, but the
horizontal size of each wave doesn't change.
If the instrument is played at a higher pitch, then the waves become shorter,
because 'pitch' is directly related to the frequency of the waves, and higher
pitch means higher frequency and more waves in any period of time.
If the instrument plays louder and at higher pitch, the waves on the scope
become taller and there are more of them across the screen.
3). The equation is: Frequency = (speed) / (wavelength)
(Notice that this is exactly the same as the equation up above in question #1,
only with each side of that one divided by 'wavelength'.)
Frequency = 300,000,000 meters per second / 1,500 meters = 200,000 per second.
That's ' 200 k Hz ' .
I didn't think anybody broadcasts at 200 kHz, so I looked up BBC Radio 4
on-line, and I was surprised. They broadcast on several different frequencies,
and one of them is 198 kHz !
Let the radius of the cylinder is r and the height is h
So, the volume of the cylinder is π r² h
If the radius is multiplied by 5
So, the new radius = 5r
And the new volume = π (5r)² h
= π (25r²) h
= 25 π r² h
= 25 the volume of the cylinder of radius r
So, if the radius is multiplied by 5, The volume of the cylinder will be 25 times larger.
Answer No 1) The correct option is a. Structures B and C are located within Structure A and code for inherited traits.
Answer No 2)
According to the most widely accepted Watson and Crick's model of DNA, the DNA comprises of two strands.The backbone of the DNA strands is made up of sugar-phosphate. The two strands are joined together by the hydrogen bonds in between the nitrogenous bases of the two strands.
The two strands of the DNA are twisted around each other and form a helix. It is due to the hydrogen bonds between the two strands and their twisting that the DNA is called the double helix.
DNA is like a recipe because the sequence of the DNA is just like the ingredients of a recipe which will be added to form the right organism.
The DNA contains nitrogenous bases which will code for the traits of a particular organism with its specific characteristics just as different ingredients make up a different recipe.
If DNA changes abnormally, then the traits of an organism will be affected. Serious complications might release due to the DNA changing abnormally.
Differences between gene and allele
1) Gene are a part of the chromosomes. Alleles are a part of the gene.
2) Genes determine the expression of a trait. Alleles will determine the variations which can arise in a particular trait.
3) Genes will produce a particular protein whereas alleles will produce a particular genotype.
Both the gene and allele will determine the particular genotype and the resulting phenotype of the organism.
a) Claim: Yes, genes do affect physical features of an organism.
Evidence: The genotype produces the resulting phenotype.
Reason: The genotype of an organism is determined by the particular alleles of the genes which make up the organism. The expression of these genes results in the physical characteristics of the organism.
b) Claim: Some DNA mutations are heritable, other are not.
Evidence: Those mutations might be carried along the germ line and hence can be inherited.
Reason: Some mutations are carried from the parents to the children and these mutations will be heritable. Other mutations might not be carried along the germ line and will non-heritable.
Drawing of the chromosome is shown in the attachment.
A chromosome is made up of different genes. Each particular gene is made up of a allele pair. The genes comprise of a section of a DNA.
This means that all the array of chromosomes in an individual will comprise of the entire DNA.
Each cell in an organism comprises of the particular number of chromosomes which are essential for the survival of that organism, Only the sex cells contain half the number of chromosomes of the somatic cells.
Answers are rectangle, rhombus and parallelogram respectively.
Step-by-step explanation:Answer to 74 is a rectangle. It has opposite sides equal and adjacent sides are perpendicular.Answer to 75 is a rhombus. It has all equal sides and opposite angles are equal, but adjacent angles are not equal. Answer to 76 is a parallelogram. It has opposite sides equal and parallel but adjacent sides are not equal.
Explanation: The US has been characterized by some as a neo-imperialist power of the 20th and 21st centuries.
a company that is considered the most effective in its industry, for example, because it sells more products, makes more profit, or has a better known brand than its competitors: The industry leader with a 30% market share, it is expected to grow 35% a year.
