Answer:

The answer is statement 1, 2, and 3

Explanation:

A hypothesis is a starting point for further investigation, therefore a hypothesis will always be a possibility at least until it is tested.

Variable is a factor that is liable to vary or change.

A hypothesis without being tested is merely a statement or an explanation made on the basis of limited evidence. Therefore it is unsure whether the said statement is true or not.

A hypothesis can still be proven by further investigation with different variables

A student does an experiment for a science fair to study whether temperature affects the timing of a cricketâ€™s chirps. The stu

nexus9112 [7]

The frequency of chirps increases as the temperature increases. The correct option is B. The chirps occur closer together as the temperature increases.

-------------------------------

<h2>Available data:</h2>

<h3>Data recorded by the student </h3>

Day Temperature Average time between chirps (sec)

1 21 2. 5

2 22 2. 6

3 23 2. 2

4 24 2. 3

5 25 2. 0

6 26 1. 8

7 27 1. 9

8 28 1. 8

9 29 1. 4

10 30 1. 2

11 31 1. 5

12 32 1. 1

In this experiment the student recorded the time in seconds between chirps.

We can see that as the temperature increases, in general, the time between chirps decreases.

At 21ºC the time between chirps is 2.5 seconds

At 26ºC the time between chirps is 1.8 seconds

At 32ºC the time between chirps is 1.1 seconds

According to this information, if the average time between chirps decreases with the temperature increase, we can assume that the frequency of chirps increases as the temperature gets higher.

<h3>Options,</h3>

A) The higher the temperature, the fewer chirps there will be in 10 seconds.

Wrong. The number of chirps in 10 seconds will depend, not only on the frequency but also on how long the chirps last. Since the student did not record the time of chirps, we can not make this conclusion.

B) The chirps occur closer together as the temperature increases.

True. The chirps increase in frequency as the temperature increases, so they occur closer together.

C) The chirps become farther apart as the temperature increases.

Wrong. We can see how the time between chirps decreases as temperature increases, meaning that they are closer not farther.

D) There is no relationship between temperature and the time between chirps.

Wrong. If we make a graph we will see the tendency and the relationship between chirps and temperature.

Graphs usually explain the relationship between variables. In this example, the relationship would be inverse.

Why is it a good idea to plant only native species in your garden

Brums [2.3K]

Answer:

Native plants do not require fertilizers and require fewer pesticides than lawns. Native plants require less water than lawns and help prevent erosion. The deep root systems of many native Midwestern plants increase the soil's capacity to store water.

This is more of a psychology question but why does the mind procrastinate and what helps it stop?

Pie

people procrastinate because they're avoiding something they know will make them emotionally unpleasant by doing that task, so instead, they do something that provides a temporary mood boost. Procrastination itself causes shame and guilt, leading people to procrastinate even further.

your physical abilities rely a lot on your mental strength, if you feel like you've been procrastinating, try doing things to boost your overall mental health.
