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:
I.
4) The deoxygenated blood then travels through the veins and enters the right side of the heart.
1) The blood leaves the heart through the aorta.
2) The blood travels throughout the body via the arteries to the capillaries.
3) In the capillaries, the exchange of nutrients and gases occurs. Oxygen is absorbed by the cells while carbon dioxide is released into the blood.
II.
2) Exchange of gases happens as oxygen is received by the blood and carbon dioxide is released.
1) The deoxygenated blood flows from the right side of the heart to go to the lungs.
3) The oxygenated blood then returns to the left side of the heart.

<h2>Answer:</h2>
<u>Typical rates of sea-floor spreading are approximately </u><u>5 cm per year</u>
<h2>Explanation:</h2>
Sea-floor spreading is a process that happens at the mid-oceanic ridge where a divergent boundary is causing two plates moving away from one another resulting in spreading of the sea floor. To calculate the spreading rate of one side of a mid-ocean ridge by dividing distance by time (Distance/Time = Rate) The typical rates of sea -floor spreading are approximately is 5 centimeter per year.
The amygdala is found in each temporal lobe and is involved with the limbic system. The amygdala is found in the medial temporal lobe, immediately prior to the hippocampus. The temporal lobes are the second biggest lobes, located behind the ears. They are most typically related with the processing of auditory information and memory encoding.
The temporal lobes' primary roles include language comprehension, memory acquisition, face recognition, object recognition, perception, and auditory information processing amygdala. The temporal lobe is in charge of understanding and assigning meaning to different sounds. As a result, injury to the left temporal lobe often leads to issues understanding language.

Think of it like this. Horses do a LOT of galloping, which is hard on the feet! Hooves are a physical ADAPTATION, so that the horses won't experience pain on their journeys. They're hard, so that the horses don't feel the ground nearly as much. Now, mountain goats travel over rough terrain, with sharp rocks and steep inclines. Again, it's really easy for them to get hurt strutting around the mountains, so they evolved hard hooves to protect their feet.
