Answer:
double helix, which is made up of a nitrogenous base, a five-carbon sugar (deoxyribose), and a phosphate group. There are four nitrogenous bases in DNA, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine).
Explanation:
The chromosomes in the sex cells would be half the chromosomes in the body cells; so since each body cell has 40 <span>chromosomes and half of that is 20, there's your answer. It's B. 20</span>
Answer:
1.33 m/s
Explanation:
The formula for Kinetic Energy is given as:
![K.E=\frac{1}{2} mv^{2} \\](https://tex.z-dn.net/?f=K.E%3D%5Cfrac%7B1%7D%7B2%7D%20mv%5E%7B2%7D%20%5C%5C)
Where, m is the mass and v is the velocity of the object. In order to tell how fast is the object moving we need to calculate its velocity.
Re-arranging the above equation and isolating v, we get
![2 K.E = mv^{2}\\\\v^{2} = \frac{2 K.E}{m}](https://tex.z-dn.net/?f=2%20K.E%20%3D%20mv%5E%7B2%7D%5C%5C%5C%5Cv%5E%7B2%7D%20%3D%20%5Cfrac%7B2%20K.E%7D%7Bm%7D)
Putting values in this equation, we get:
![v^{2}=\frac{2 \times 32}{36}\\\\ v^{2}=\frac{16}{9}\\\\ v=\frac{4}{3}\\\\ v=1.33](https://tex.z-dn.net/?f=v%5E%7B2%7D%3D%5Cfrac%7B2%20%5Ctimes%2032%7D%7B36%7D%5C%5C%5C%5C%20v%5E%7B2%7D%3D%5Cfrac%7B16%7D%7B9%7D%5C%5C%5C%5C%20v%3D%5Cfrac%7B4%7D%7B3%7D%5C%5C%5C%5C%20%20v%3D1.33)
Thus, the object is moving with a velocity of 1.33 m/s
Answer:
No osmosis occurs. Red blood cells placed in a solution with a higher water concentration compared to their contents (e.g pure water) will gain water by osmosis, swell up and burst. Water will diffuse from a higher water concentration outside the cell to a lower water concentration inside the cell.
Answer:
Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.
