Independent variable: FERTILIZER.
 This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.
Hypothesis: THE TYPE OF FERTILIZER USED IN CULTIVATING HYDRANGEA FLOWER AFFECT THEIR COLOR.
 An hypothesis is a generalized statement which predicts the relationship between the variables you are examining. 
Control group: THE GROUP THAT DID NOT GET ANY FERTILIZER
The control group is the group that does not receive any treatment. 
Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment. 
Constants: TYPES OF SOIL USED, MORNING SUNLIGHT, WATER AND THE NO OF DAY THE EXPERIMENT LAST.
The constants are the inputs into your experiment which you give to all the groups.

1. Independent variable: type of fertilizer

2. Dependent variable: color of hydrangea flowers

3. Hypothesis:  The type of fertilizer changes the color of their hydrangea flowers.

4. Control group: One bush gets no fertilizer.

This bush is their basis of comparison on what changes the type of fertilizer have on different bushes.

5. Experimental group: 9 bushes where every bush gets 3 cups of fertilizer, but each receiving a different brand.

Since there are 10 hydrangea bushes and 1 of these is the control group, the rest are experimental groups.

6. Constants: - Variables that are the same all throughout the experiment.

* Planted in the same yard with the same type of soil.

* All bushes receive morning sunlight and no afternoon sunlight

* All bushes are watered the same amount every other morning.

A researcher is trying to design an experiment to measure the amount of energy a person uses during different activities. He pro
Tomtit [17]

The right answer is to measure the amount of released carbon dioxide.

The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.


A is false because glucose is not found in the urine, except in the case of diabetes mellitus.

C is false because the consumption of calories does not mean that we will directly use it.

D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.

The current population of a threatened animal species is 1.6 million, but it is declining with a half-life of 25 years. How many animals will be left in 35 years<u> The decay law i</u>

<u>p(t) = 1,700,000 (1/2)t/25</u>

<u>where t is in years and p(t) is the population at time t.  Plug in 40 and 55 for t.</u>

<h3>What is threatened animal?</h3>

Any species (including those of animals, plants, and fungi) that is likely to become endangered in the near future is considered to be a threatened species. The population dynamics measure of critical depensation, a calculation of biomass related to population growth rate, is occasionally used to identify threatened species. This quantitative indicator is one way to gauge how endangered an area is. When discussing IUCN categories, the terms threatened and vulnerable may be used interchangeably; however, threatened generally refers to the three categories (critically endangered, endangered, and vulnerable), whereas vulnerable generally refers to the category that is least at risk among the three. However, since all threatened species are vulnerable species, they can usually be used interchangeably.
