Explanation:
Peptide bonds are essential in the formation of a protein's primary structure, but they do not contribute to the tertiary structure.
Answer:
1. C
2. D or C
3. B
4. Heat will be transferred through molecular collisions from the hotter system to the cooler system.The thermal energy will flow in that direction until the two objects are at the same temperature.
5. The strawberries will start to get colder and freeze.
Hope this helps
This questions seems to be a question where you are required to mention more than one point. The question has two options of course, I'll tell you my personal answer to the question in broken up points.
I disagree with this statement because I believe that Physical Education (PE) is a very important subject for each individual.
It has been proven that any sort of physical education improves the activity of your brain, if an individual's level of brain activity is higher, it means he learns more from other education and performs better on his tests.
Physical Education is also a practical lesson that relieves stress off students from all the other core subjects that do not that involve as much practical activity.
Physical Education makes you healthier, the healthier you are the better your life style and (technically) life time will be.
Physical Education is also now proven to wake up students, this means students are less lazy and goes back to one of my previous points mentioning a students activity and performance in a lesson or a test.
I hope this helped, any other questions let me know. :3
The correct answer is B. The pickup truck is moving at 4 m/s and the school bus is moving at 2 m/s.
Explanation:
The kinetic energy is related to how fast a body moves (speed), as well as, the amount of matter in the object (mass). Due to this, even if the bus and the truck move at the same speed they do not have the same kinetic energy. Indeed, the graph shows in general the kinetic energy is higher for the school bus.
However, this does not occur if the truck moves at 4 m/s and the bus moves at 2m/s because, at this speed, the kinetic energy of the truck is 30 kilojoules, while the kinetic energy of the bus is around 15 kilojoules, which is lower. According to this, the correct answer is B.
