The four systems that describe the functions of the circulatory systems are:
- oxygen is delivered to cells throughout the body by this system
- This system removes carbon dioxide from organs & delivers it to the lungs.
- Carbon dioxide exits the body through this systems
- This system's organs pass oxygen into the bloodstream.

What is the circulatory system?
The circulatory system can be referred to as a system of organs that includes the heart, blood vessels, and blood which is circulated throughout the entire body of humans or other vertebrates.
The circulatory system includes the cardiovascular system, also known as the vascular system which consists of the heart and blood vessels.

Answer:
The officer that allows people in and out of the crime scene.
Explanation:
The cell membrane chooses what comes in and out of the cell, therefore the officer would be most similar to the job of the cell membrane.
Answer:
blood hormone level will increase
Explanation:
since once food reach the stomach it will trigger different hormone process that cause release of enzymes required to digest carbohydrate
The correct answer is - False.
To trace the correlation between the rock layers by using fossils can be a big mistake, though occasionally it may provide the proper information, still it will be relying on luck.
The case is actually the other way around, the fossils can be correlated by using the rock layers, because each layer of rocks represents some time in the geologic past.
The fossils, on the other hand, are much more easy to be moved through the layers over time, because there can be disturbances, adjustments in the crust, or the rocks can change their composition under the influence of multiple factors. All of that can contribute to the fossils ending up at places where they aren't expected to be, so using them to correlate the rock layers will not be a very useful method.
Step 1: DNA replication begins at the origin of replication
Step 2: Helicase cuts hydrogen bonds and separates DNA in half
Step 3: Single strand binding proteins attach and keep the DNA molecules separated.
Step 4: The replication fork is formed with the leading and lagging strands
Step 5: In the leading strand RNA primase moves along nucleotides and coats with a RNA primer.
Step 6: DNA polymerase attaches post primase to DNA nucleotides and moves along towards the replication fork in 5 prime --- 3 prime direction. It adds nucleotides to the half DNA molecules
Step 7: Another type of polymerase replaces the primer with DNA nucleotides so all DNA is there
Step 8: Ligase stitches up the gaps.
Hope this helps!!!
