The kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.
<h3>How to calculate kinetic energy?</h3>
The kinetic energy of a moving car can be calculated using the following formula:
K.E = ½ × m × v²
Where;
- K.E = kinetic energy
- m = mass
- v = velocity
K.E = ½ × 1324 × 20²
K.E = 264800J
Therefore, the kinetic energy of a car with a mass of 1,324 kilograms, traveling at a speed of 20 meters seconds is 264800J.

Ans.
The biodiversity of a coral reef ecosystem will be decrease if there is a decrease in coral reef population as most if the marine organisms, such as microbes, sea urchins, plankton, fishes, seahorses, along with larger animals, such as sea turtles, directly or indirectly depend on coral reefs. As seaweeds act as competitors of corals, overgrowth of seaweed population would decrease population of corals.
This will lead to a disturbance in coral reef ecosystem and decrease the ecosystem's biodiversity. Thus, the correct answer is 'option B). the overgrowth of seaweed would prevent light from reaching the reef.'
<span>Type 2 alveolar cells or pneumocytes are the cells responsible for secreting pulmonary surfactant. Their function is important as the pulmonary surfactant is required to decrease surface tension within the alveoli. They are capable of cell division which in turn produces more of these alveolar cells when there is damage to the lung.</span>
Answer:
An organism interacts with both the living and nonliving parts of its habitat.
Explanation:
Biotic FactorsThe parts of a habitat that are living, or once living, and that interact with an organism are called biotic factors.
The answers are insertion, deletion and substitution respectively.
<h3><u>Explanation</u>:</h3>
The mutation is the phenomenon which includes some alteration of the genetic material of the organism by either insertion, deletion or substitution of one or more nitrogen base pairs by others. This phenomenon was invented by Scientist Sir Hugo de Vries, who was also called as the Father of Mutation.
The insertion includes the addition of one or few nitrogen base pairs within the DNA which changes the codon pattern, thereby changing the protein coded from that part of DNA. T
The deletion includes the deletion of a part of DNA with similar effect as that of Insertion.
The substitution is the change of nitrogen bases by other bases which also leads to change in protein produced by the part of Genetic material.
