Oh boy, there's many, many, many, many...
(many x100)
many ways!

One way is to take shorter showers and conserve water wherever you go, at home, at a restaurant, hotel, etc.

Another way is to not litter on the streets.

Or, spread the word and tell everyone to conserve water, not litter, or just anything to help the environment!

Answer:

two sets of magnifying lenses

Explanation:

This is because a compound microscope is a high magnifying microscope that have multiple lenses or two magnifying lenses which help to see or observe or magnify image very well compare to single lense. It is a high power microscope and it has high level of magnification because of the

If the number of cigarettes smoked increases, then the risk for lung cancer increases. Independent variable: _______ Dependent v

hodyreva [135]

Complete Question:

Part A: Identifying Variables

Read the following hypotheses and identify the variables.

If the number of cigarettes smoked increases, then the risk for lung cancer increases.

Independent variable: _______

Dependent variable: _______

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.

Independent variable: _______

Dependent variable: _______

If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.

Independent variable: _______

Dependent variable: _______

Answer/Explanation:

Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.

Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.

In the above given hypotheses, the dependent and independent variables are shown below:

1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".

"Risk for lung cancer" => dependent variable

Number of cigarettes => independent variable

2. "number of shark attacks on humans" is dependent on "number of sharks swimming".

Dependent variable => number of shark attacks on humans

Independent variable => number of sharks swimming

3. Dependent variable => strength of bone

Independent variable => amount of milk a person drinks

Lelechka [254]

Answer: Comparing the DNA sequence of the organisms can also tell you how closely related species they are. It can give you even more information since the original DNA is how the amino acid sequence of cytochromes is coded for.

Looking at embryonic development also helps you determine the phylogeny of organisms because a way an embryo develops can be very similar to the way another species develops but then both are full-grown they look very different and its tuff to explain how close they might be related
