D. Chromosomes are mainly made up of DNA. Down's Syndrome: Down's syndrome is caused due to the presence of an additional copy of chromosome 21 (Trisomy of 21). All Science And Technology Solutions Solutions for class Class 9 Science are prepared by experts and are 100% accurate. • A phosphate group is linked to 5'-OH of a nucleoside through phosphoester linkage to form a corresponding nucleotide. Chapter 12 lab extracting dna answer key. • A nitrogenous base is linked to the ribose sugar through N-glycosidic linkages to form a nucleoside (like adenosine, guanosine or cytidine and uridine). C. |Monohybrid cross||Dihybrid cross|. Science And Technology Solutions Solutions for Class 9 Science Chapter 16 Heredity And Variation are provided here with simple step-by-step explanations. 4) Telocentric chromosomes: In telocentric chromosomes, the centromere is present at the terminal end. It was the first discovered and described chromosomal disorder in humans. If a carrier/sufferer of a genetic disorder marries a person who is also a carrier/ sufferer of the disorder, then there are chances that disorder will be passed on to the offsprings.

D. A RNA nucleotide has three main components − a nitrogenous base, a ribose sugar and a phosphate group. The total number of chromosomes in people affected with Down's syndrome becomes 47. Monogenic disorder||Pale skin, white hairs|. As a result, the chromosome has only one arm. • Two types of nitrogenous bases are present i. e. Dna and rna worksheet answer. Purines (Adenine and Guanine) and Pyrimidines (Cytosine and Uracil).

Example- a cross between tall and dwarf plant||. E. Organisms produced through sexual reproduction show major variations. 44+X:Turner syndrome::44+XXY:-.............. Genetic disorders are not communicable diseases that would be transmitted to people who come in contact with people with genetic disoders. There is no particular treatment for sickle cell anemia, the treatments which are available provide symptomatic relief from the symptoms associated with this disorder. View NCERT Solutions for all chapters of Class 9. It can be used for studying evolution and genetic diversity in a population. Hereditary characters are transferred from parents to offsprings by gene, hence they are said to be structural and functional units of heredity. • Every nucleotide residue has an additional −OH group present at 2' -position in the ribose.

As a result, it has one arm, which is extremely long and the other, which is extremely short. A dihybrid cross is useful in studying the assortment of the offspring. A. Chromosomes are thread-like structures found in the nucleus of all living cells. The applications of DNA fingerprinting are as follows: -. DNA fingerprinting forms the basis of paternity testing since a child inherits polymorphism from both its parents. What is meant by 'chromosome'. D. No, it is not right to avoid living with a person suffering from a genetic disorder.

Question 5: How are the items in groups A, B and C inter-releated? Explain Mendel's monohybrid progeny with the help of any one cross. It is a result of replacement of GAG by GUG leading to the substitution of Glu by Val at sixth position of beta globin chain of haemoglobin. 44+XXY||Pale skin, white hairs|. C. The component which is in the nuclei of cells and carries the hereditary characteristics is called chromosome. It is the remaining 0. There are 3 types of RNA: 3. rRNA (ribosomal RNA) − These are the work benches of translation.

44+XXY||Men are sterile|. E. It is necessary for people to have their blood examined before marriage because the genetic disorders are transmitted only by reproduction. The DNA molecule is made up of basic materials called nucleotides and each nucleotide is made up of three components: - Sugar. 3) Acrocentric chromosomes: In acrocentric chromosomes, the centromere is located close to the end of the chromosome. • Many nucleotides are linked through 3'-5' phosphodiester linkages to each other to form the polynucleotide chain. Nitrogen bases are attached sugar from inwards that extends to join hydrogen bond and the complimentary nitrogenous base from other strand. Leber hereditary optic neuropathy|| Mitochondrial. B. Monogenic disorders: Monogenic disorders are genetic disorders which are caused by a mutation in a single gene.

Let me do all the vertical stuff that we wrote in blue. And this rocket is going to launch a projectile, maybe it's a rock of some kind, with the velocity of ten meters per second. A soccer ball is traveling at a velocity of 50m/s 2021. Gravity only affects the vertical component of the projectile's travel. And we're going to use a convention, that up, that up is positive and that down is negative. By clicking Sign up you accept Numerade's Terms of Service and Privacy Policy. We have to hypotenuse, so once again we write down so-cah, so-ca-toh-ah.

A Soccer Ball Is Traveling At A Velocity Of 50M/S Rocket

I'll just round to two digits right over there. Actually, there are several types of kinetic energies. How do you know that the initial vertical velocity and final velocity are equal in magnitude? So let's think about how long it will stay in the air. The work-energy theorem. The -5m/s comes from the instant before it reaches the launch point again. So this velocity vector can be broken down into its vertical and its horizontal components. 02 seconds So our change in time, so this right over here is 1. The horizontal velocity is constant. Projectile at an angle (video. We assume this to be true since we are also assuming that there is no air resistance. And you might not remember the cosine of 30 degrees, you can use a calculator for this.

The key information is what kind of object we are talking about. So to figure out the actual component, I'll stop to get a calculator out if I want, well I don't have to use it, do it just yet, because I have 10 times the square root of three over two. Times the amount of time that passes by. So in 1 second the object would move that far. The acceleration is what is actually causing the velocity to change, so if you multiply the time by the acceleration, the answer will be how much the acceleration caused the velocity to change (change in velocity)(11 votes). Voiceover] So I've got a rocket here. I have, this is the same thing as positive 10 divided by 9. It looks very similar to the kinetic energy equation because we replace mass with density, which isn't coincidental. Which is going to be 10 divided by two is five. Times the cosine, times the cosine of 30 degrees. When it falls back down, isn't the velocity just gravity? A soccer ball is traveling at a velocity of 50m/s web. Let's consider a bullet of mass.

A Soccer Ball Is Traveling At A Velocity Of 50M/S Web

It's important to realize you can separate the flight of the projectile into its vertical component and horizontal component, solve them separately, and get valid results for the actual flight of the projectile. 10, sin of 30 degrees. Just before it hits the ground, the projectile has some downward speed. The displacement is the average velocity times change in time. A soccer ball is traveling at a velocity of 50m/s rocket. The most popular and commonly used kinetic energy units are: - Joule (J), equivalent to kg·m²/s² – SI unit; - Foot-pound (ft·lb) – imperial unit; - Electronvolt (eV); - Calorie (cal); and. You can easily find it out by using our kinetic energy calculator. So it's gonna be five, I don't want to do that same color, is going to be the five square roots of 3 meters per second times the change in time, times how long it is in the air. So we're gonna get some vertical component, some amount of velocity in the upwards direction, and we can figure, we can use that to figure out how long will this rock stay in the air. So how do we figure out the vertical component given that we know the hypotenuse of this right triangle and we know this angle right over here. And its horizontal components. A and B hit the ground at the same time.

We haven't even thought about the horizontal. Here's an interesting quiz for you. Projectile Motion Quiz Questions With Answers - Quiz. So the first that we want to do is we wanna break down this velocity vector. Change in velocity, in the vertical direction, or in the y-direction, is going to be our final velocity, negative five meters per second, minus our initial velocity, minus five meters per second, which is equal to negative 10 meters per second. The two '2's will cancel each other out, leaving us with 5*sqrt(3). It's related to the motion of an object traveling in a particular direction and the distance it covers in a given time.

A Soccer Ball Is Traveling At A Velocity Of 50M/S 2021

But the problem is we aren't sure when the ball hits the ground. As you can see, depending on the scale, they may differ by a significant number of orders of magnitude, so it's convenient to use scientific notation or express them with some prefix like kilo- (kcal, kWh), Mega- (MeV), etc. Constant acceleration. We assume that the elapsed time is a positive one. If you don't know the object's speed, you can easily calculate it with our velocity calculator. The relation between dynamic pressure and kinetic energy. Over 10 meters per second. What is the kinetic energy of football during a field goal kick? 83 meters, just to round it.

And, if we assume that air resistance is negligible, when we get back to ground level, we will have the same magnitude of velocity but will be going in the opposite direction.
