Tiktaalik roseae was discovered in sediments on Ellesmere Island in Nunavut, Artic Canada (Ahlberg and Clack, 2006). The sediments it was found in are from what is known as the Fram Formation, which is thought to be deposits of lowland streams (Murphy, 2005). hope it helps
<u>Answer:

When the outer electron shell is full in an element, this creates a Noble gas.
<u>Explanation</u>:
Noble gases are the elements that belong to group 18 in the periodic table. Noble gases are also called as inert gases. The outermost shell of the noble gases are fully filled by electrons. Due to this the noble gases don’t react with any other elements and remain isolated.
There are 6 noble gases in the periodic table. They are helium (He), Argon (Ar), Neon (Ne) Krypton (Kr), Radon (Rn) and Xenon (Xe). Noble gases conduct electricity. They are fluorescent, odorless and colorless. Noble gases are used a maintain stable elements in a constant and safe environment.
Regurgitation influences the flow of blood by mixing the oxygen-poor blood with the oxygen-rich blood. Due to this, the heart has to pump more to oxygenate the entire body, leading to the rapid, and fluttering heartbeat. The tissues get oxygenated but regurgitation could be fatal, as the heart cannot function overtime forever.
Valve prolapse influences the flow of blood when the flow of blood backs up. This leads to an irregular or racing heartbeat. Even at certain occasions, the blood can flow back to the lungs. However, there is not a huge influence in the oxygenation of the body tissues.
Stenosis makes the ventricles to pump overtime to get enough blood through, and in the process, the ventricles thicken. This functions for a while, however, it will result in heart failure as the heart cannot do it for entire life. The tissues are oxygenated, but it will be an issue due to overtime.
Answer: The question is not complete, here are the options.
Which statements best describe this scenario? Check all that apply.
A. The potato plant is parasitic.
B. The dodder plant is parasitic.
C. The potato plant will grow stronger.
D.The potato plant stays alive because of
E. The dodder plant stays alive because of the potato plant.
The correct options are A and E.
Explanation:
This is because dodder plant is a parasitic plants that survive and live on the host plants there by causing harm or destroying the host because it survive on the resources needed for the host survival. Dodder plants twine around the potatoes and obtain nutrients and water from the potatoes through it root system.
Population density refers to the determination of population in a unit area or unit volume. It is generally applicable to the living species, and majorly to the humans. It is an essential geographical term and its a quantity of type number density.
In the given case, it can be seen that New Zealand exhibits a smaller population in comparison to Australia, but it has a greater population density as it encompasses a much smaller region.
On the other hand, the population of Australia is about five times more than New Zealand, but Australia covers about 30 times more area in comparison to what New Zealand covers.
