Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Answer:
Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.
Explanation:
The air travels through the respiratory system during inhalation in the next order:
- <em><u>Nasal cavity:</u></em> You inhale air into your nose.
- <u><em>Larynx:</em></u> The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
- <u><em>Trachea:</em></u> (Or <em>windpipe</em>) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
- <em><u>Bronchi:</u></em> The trachea divides into two primary bronchi; they are the main passageway into the lungs.
- <em><u>Bronchioles: </u></em>The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
- <em><u>Alveoli:</u></em> They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
The whale and the bat are the most different because of the size of the hands or fins.
And the human and the cat are the most similar because they are almost identical to each other from the bottom up
You can conclude that the one that were alike were related in some type of way
Answer:
No
Explanation:
Replication happens at a much faster rate in prokaryotes than in eukaryotes.
Answer:
cancellation
Explanation:
A factor in the numerator is <em>cancelled by dividing it</em> by the same factor in the denominator. The quotient is 1, the multiplicative identity element.
