Biology

A: In a lab a scientist measures the height of roses that received different fertilizers.

An experiment must include variables. The other three are just measurements, but since the scientist is varying the types of fertilizers used, this better describes an experiment. It is also done in a controlled environment (in a lab) which helps to eliminate other uncertainties.

How does carbonic anhydrase change the reaction between carbon dioxide and water?
Natalka [10]

It catalyzes the reaction by making it fast (both forward and reverse reactions).

Naturally, the reaction between CO2 and H2O is very slow in the formation of carbonic acid. However, in the blood, due to the presence of the enzyme, the reaction is much rapid by millions of factors.

Answer:

With the findings of the 2016 Census count on population and dwellings, Statistics Canada gives Canadians a first look at the most recent national statistical snapshot.

The census counts 35,151,728 persons who said they lived in Canada on May 10, 2016, and displays population growth patterns across the country.

The organization will provide the complete spectrum of census data during the following year, as Canadians commemorate 150 years since Confederation, in order to portray a truthful picture of Canadians' lives and communities.

In 1871, the first census following Confederation recorded 3.5 million people in Canada, while the population figure in 2016 was ten times higher. When Canadians celebrated the 100th anniversary of Confederation in 1967, that number had risen to 20.0 million people (1966 Census).

Canadians have been making their way west for many years. The four founding provinces of Ontario, Quebec, New Brunswick, and Nova Scotia housed the majority of Canadians in 1871, whereas Western Canada was lightly populated. Manitoba, Saskatchewan, Alberta, and British Columbia accounted for over a third of the population in 2016.:
