<em>Answer:</em>
<em>The answer for this statement is "True".</em>
<em>Explanation:</em>
<em>In the kidneys, the countercurrent mechanism involves the interaction between the flow of filtrate through the loop of Henle of the juxtamedullary nephrons (the countercurrent multiplier) and the flow of blood through the limbs of adjacent blood vessels (the countercurrent exchanger). This relationship establishes and maintains an osmotic gradient extending from the cortex through the depths of the medulla that allows the kidneys to vary urine concentration dramatically which is true.</em>
Two examples of related organisms are dinosaurs/chickens, and the megalodon/the great white shark.
<h3>How have organisms evolved?</h3>
Life emerged on our planet 3.7 billion years ago, and since then organisms have evolved or changed over time this includes:
- The appearance of more complex organisms, which is the result of natural selection.
- The diversification of organisms.
- The extinction or disappearance of species.
This has caused all organisms that exist today to be related to other organisms of the past. Let's examine two examples.
<h3>Dinosaurs and chickens: </h3>
According to scientific research, birds evolved from dinosaurs. Indeed, it has been determined birds started with theropods, which were a specific group of dinosaurs.
This means modern birds including chickens are related to this group of dinosaurs, even if overtime birds have evolved a lot and they might not seem to be very similar to dinosaurs.
<h3>The megalodon and the great white shark:</h3>
These two species of shark likely share a common ancestor and due to this, both species have many similarities such as the shape of their teeth. However, megalodons are extinct, while great white sharks still exist today.

The experiment shows that the cells can divide themselves to fill in the empty space
Answer:
Analysis
Explanation:
This is the process of analyzing and organizing data in tables, graphs, etc. A. experimentation is wrong because it is testing your hypothesis. You take data from experimentation. D. hypothesis is wrong because a hypothesis means thinking of what you THINK will happen in your experiment using an if, then statement. hope this helped!
