The looping of DNA around histone proteins... a. Produces the characteristic helix shape of the DNA b. Allow the room for cellular machinery to reach all genes so they may be transcribed c. Compacts the DNA allowing a large amount of DNA to fit into the cell d. PreventS the DNA from becoming kinked and breaking e.
Despite the humpback whale and whale shark being similar in size, they are not as closely related as the humpback whale is to the spider monkey, which is far smaller in size. This provides evidence that size of a specie is not a good indicator of its relationship to other species.
I temperature will continually rise until it melts assuming you do not stop applying heat to the ice. It doesn’t really matter at what temp below freezing you start as long as you go above freezing the ice will melt.
Because each strand in DNA that is created contains a Helix that is copied! :) Hope this helps.
Answer:
Ralph is looking at a vein (likely a muscular vein).
Explanation:
Of all three great types of vessel present in vertebrates (arterial, venous, lymphatic), only veins and lymphatic vessels may normally contain valves. This is an essential feature of vessels which present low pressure flow, since it ensures that such flow is unidirectional.
Since blood cells are not typically found in lymphatic vessels, the vessel in question can be assumed to be a vein.
