Write a reflection outlining what this tells you about Canada’s population density. What other information does this tell you
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.:
Which of these do scientists change when new evidence conflicts with old
ideas?
A. Experimental variables
B. Experimental results
OC. Scientific methods
OD. Scientific theories
Scientists change scientific theories when new evidence conflicts with old ideas; option D
What are scientific theories?Scientific theories are explanations put forward by scientists to explain a given observation based on current research.
Scientific theories can be modified based on changing evidence due to further research.
Therefore, it can be concluded that when new evidence disproves old ideas, scientists modify and adjust scientific theories to harmonize with new evidence.

What are characteristics of allosteric enzymes?
The characteristics of allosteric enzymes are regulatory molecules can bind and modify the catalytic activity of these enzymes.
What are the main characteristics of enzymes?Enzymes are proteins that catalyze chemical reactions that occur in living things. They speed up the speed of reactions, which contributes to metabolism. Without enzymes, many reactions would be extremely slow. During the reaction, the enzymes do not change their composition and are not consumed either.
In this case, Allosteric enzymes are enzymes that contain a region separate from the substrate to which small regulatory molecules can bind and modify the catalytic activity of these enzymes.

After an investigation, Kuri determines that her hypothesis was wrong. What is the best thing for Kuri to do next?
propose a scientific theory that explains what went wrong
write a new hypothesis and conduct new experiments to explore the matter
rewrite a scientific law to better predict the observations she gathered
move on to a different topic because there is no value in a wrong hypothesis
Write a new hypothesis and conduct new experiments to explore the matter. Thus, option "B" is correct.
What is the Hypothesis?Hypothesis
The formulation of hypotheses is one of the key steps in the scientific method.
Hypotheses are usually tested using experiments and are usually accepted or rejected depending on the outcome of the experiments.
If a hypothesis is rejected, it does not mean that the entire subject is abandoned. Rather, new hypotheses may be formed and experiments conducted to further explore the subject.

The correct answer will be
1. Motor neuron
2. Spinal cord to muscle
In a Reflex arc, the Motor neuron carries the action potential from the Spinal cord to muscle.
The following are the components of a reflex arc:
A stimulus-detecting receptorA sensory neuron that will transmit the data to the spinal cord.A processing interneuron for the data (not present in all reflexes)A neuron that transmits signals to an effector organAn organ that carries out the reaction action.A brain circuit that manages a reflex is called a reflex arc. In vertebrates, the majority of sensory neurons synapse in the spinal cord rather than passing directly into the brain.
When Juan picks up a steel utensil the receptor detects the stimulus. A sensory neuron transmits the data to motor neuron which activates spinal cord which then signals the effector organ to carry out the reaction action i.e., Juan immediately drops the hot Utensil.

Explanation:
Determine whether the statement is true or false, and why. “If a theory becomes supported by evidence, it can become a law.” A. False, it should read, “A theory and a hypothesis are already equally supported by evidence, but they have different functions.” B. False, it should read, “If a theory becomes supported by evidence, it can become a hypothesis.” C. False, it should read, “A theory and a law are already both supported by evidence and are equal, but they have different functions.” D. True
The statement "If a theory becomes supported by evidence, it can become a law" is false because it should read, “A theory and a law are already both supported by evidence and are equal, but they have different functions.” Thus, the correct option is C.
What is Evidence?Evidence may be defined as the general body of attributes or information suggesting whether speculation or recommendation is authentic or valid.
In scientific methods, both theory and law are supported by evidence but they have different functions.
The function of theory illustrates an explanation of the statements and discoveries accumulated during the process.
While the function of law illustrates an experimental circumstance in nature that is genuine whenever it is positioned to experiment.
Therefore, it is well described above.

50,000 x 0.10 = 5,000J energy did the zooplankton get from the phytoplankton. thus option B is correct.
What do you mean by food chain?In ecology, the food chain is the flow of substance and energy from one organism to another in the form of food.
A process cycle from producer to consumer to decomposer is referred to as a food chain.
Plants, herbivores, omnivores, and carnivores all exist. Beginning with plants, moving on to herbivorous insect, spiders, a small bird, a snake, a hawk, a fox, and a lion When a person passed away, a hyena would consume their body. When the hyena passed away, the body would disintegrate, becoming food for worms, and then become fertilizer for plants. so according to 10 percent rule, zooplankton get 5000 j of energy from phytoplanktons.

Answer:
A.) conversion of chemical energy to heat energy
D.) Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
D.) The populations of marsh snails and painted turtles will decrease.
Explanation:
When energy is stored in wood, it is being stored as chemical energy. This energy is being stored in the bonds that hold the wood molecules together. Once you begin to burn the wood, these bonds are breaking. As this happens, the chemical energy turns into heat energy (aka. thermal energy) and is released into the atmosphere.
Photosynthesis converts light energy from the sun into chemical energy that can be accessed by the plant later. During cellular respiration, the plant breaks down the molecules which store the energy in the form of chemical energy and accesses the energy.
When you decreases the amount of phytoplankton, the marsh snails have less food to feed on. As a result, more phytoplankton will starve. This results in the decrease of the marsh snail population. Because the marsh snail population decreases, the same will happen to the painted turtles.
A.) conversion of chemical energy to heat energy
D.) Photosynthesis creates energy that the plant stores, and cellular respiration utilizes the energy.
D.) The populations of marsh snails and painted turtles will decrease.

In analyzing the number of different bases in a DNA sample, the result would be consistent with the base-pairing rules is A+G = C+T.
What is the RNA base pairing rule?Base pairing occurs precisely: a purine base binds to a pyrimidine – adenine (A) on one chain pairs with thymine (T) on the other and guanine (G) pairs with cytosine (C).
In this case, the base pairing rule states that the number of adenine is equal to number of thymine. Similarly, the number of guanine is equal to number of cytosine.
