We see the full moon when it is in the middle of its cycle, but we see only a small part of the moon at the beginning or end of its cycle.

a sequence that happens at regular times

an event that happens once only

a set of stages that starts again after it finishes

series of events that are repeated in the same order

a series or sequence of events that happens regularly

a process that repeats itself

a process that we cannot predict

a set of stages that always follows the same pattern

Which answers best explain the meaning of cycle? Choose the 3 correct answers.

Response:

a series or sequence of events that happens regularly

a process that we cannot predict
Feedback:

A cycle is a set of stages that form a process. The stages of the process are repeated on a regular basis, so we can predict what the next stage of a cycle will be. If the process occurs only once, then it is not a cycle.

Multiple choice question

This exercise focuses on what we can learn from cycles.

Understanding cycles can help us to predict when something will happen and to take appropriate action in advance. This is why researchers in different fields - from economics to earthquakes - are trying to find out whether events in their fields occur in cycles.

We can learn more about when things will happen and why.

We can prepare for events instead of just reacting to them.

We can prevent events from happening.

Read this paragraph and answer the question below.

All cycles in the world of biology repeat themselves.

All cycles in the biological world work at the same rate.

The cardiac cycle is faster than the respiratory cycle.

Biological Cycles

The main systems in biology have cycles which repeat themselves over different lengths of time. Some cycles, such as the cardiac cycle, better known as heart beats, recur frequently. Others, such as the respiratory cycle, which is the act of breathing, repeat themselves at a much slower rate. In sharp contrast, there is the life cycle itself which recurs over a much longer period of time.

According to this paragraph, which of the following answers are true? Choose 2 correct answers.

Response:

The cardiac cycle is faster than the respiratory cycle.

All cycles in the world of biology repeat themselves.

All cycles in the biological world work at the same rate.
