Answer: it is difficult because it is necessary to understand some concepts used in a system. For example what is a boundary, and environment which can be positive or negative, etc. A sample could be the course OpenLearn that provides an example of Computing & IT.
Explanation:
This is because twenty-four latitude lines were chosen so that 24 hours represents a 360 revolution around the planet. As earth spins on its axis, different places receive sunlight at different times. Each day goes from morning to night as earth turns because the earth spins from west to east therefore the day moves from east to west. Lines of longitude help us keep track of time differences from place to place. Mapmakers divided earths 360 degrees of longitude by 24 hours which results to 15, the time changes by one hour every 15 degrees. It is one hour earlier every 15 degrees of longitude to the west and it is one hour later every 15 degrees of longitude to the east.
The fourth option: 2 C’s are connected by 3 parallel lines...
3 parallel lines represent a triple bond
Answer: humans have a very high brain-weight-to-body-weight ratio, but so do other animals. ... Other intelligent animals, such as monkeys and dolphins, also have these folds in their cortex, whereas mice have smooth brains, he said. Humans also have the largest frontal lobes of any animal, Holland said.
Explanation:
Answer:
C. primary consumers to secondary consumers.
Explanation:
An eco-system is a set of living and non living organisms living in a certain area where they interact with each other to fulfill their life requirements. One of the every important component of any eco-system is food chain.
What is food chain?
- Food chain is a series of events which involves the living organisms and the process of obtaining their food and nutrition from one organism to another.
- A food chain starts when the autotrophs or producers or plants produce their food through the process of photosynthesis.
- The next organism of food chain are primary consumers that eat plant based foods. These are called herbivores. For example: rabbit
- The next sequence organism of food chain are secondary consumers that eat primary consumers. These are called secondary consumers. For example: snakes that eat rabbit.
- The next sequence organism of food chain are Tertiary consumers that eat secondary consumers. For example owl which eats snakes.
So based on above information we can say that flow of energy in an eco system is as:
- Sun --> Producers --> primary consumers --> secondary consumers -->Tertiary consumers
Therefore, only option C is correct.
Hope it help!
