Answer:
nucleic acids and phospholipids
Explanation:
- Phosphorous is required to make two essential molecules in the body- the nuclei acid and the phospholipids.
- The nucleic acid contains carbon, hydrogen, oxygen, nitrogen, and phosphorus and is organic compounds that codes for the genetic information in an organism. There are two types of nucleic acid- ribonucleic acids and deoxyribonucleic acids, i.e RNA and DNA respectively. Both of them sugar-phosphate backbone and therefore, phosphorous is essential for the synthesis of nucleic acids in the body.
- Phospholipids make up the cell membrane and thus, phosphorous is also essential for their synthesis.
Answer:
rapid climate
Explanation:
rapid climate could affect the rainforest by increasing the temperature and driving animals far away
Answer: The average speed of the toy car during the two trials is 2m/s.
Explanation:
Speed can be defined as a type of scalar quantity in physics through which the rate at which an object travels through a distance is measured in a given amount of time. The formula for determining the speed of a car is:
Speed= distance/ time which has an SI unit of m/s.
From the speed tests carried out on a toy car, the speed of trial 1 is:
Distance= 10 meters
Time= 5 seconds
Therefore trial one speed is 10/5= 2m/s
While the speed of trial 2 is:
Distance= 40meters
Time= 20 seconds
Therefore trial 2 speed is 40/ 20= 2mls
Average speed of the toy car during the two trials is: Sum of both both speeds divided by total number of trials.
Therefore: 2 m/s + 2m/s / 2= 2m/s
From the calculation, the average speed of the toy car during the two trials is 2m/s.
Answer:
Continental Polar Air Masses: cold temperatures and little moisture. Those who live in northern portions of the United States expect cold weather during the winter months. These conditions usually result from the invasion of cold arctic air masses that originate from the snow covered regions of northern Canada.
