Examine this image and choose the most accurate statement base on relative dating.
Vlada [557]

Hello!

One of the most basic examples of relative dating, specifically in this case, would be the law of superposition. This simply states that out of many layers of rock, the oldest would be at the bottom and the youngest on top, so therefore the age of the fossils inside the rock would also increase when going down the layers. Therefore, we see that layer a is the oldest, and layer g is the youngest.

This disproves the first answer choice - the fossils in layer g are the youngest, not the oldest. Now, when comparing Layer F and D, we see that the rock layer F is above layer D. This means that layer F is younger than layer D (and same for the fossils in those respective layers). The third choice is incorrect as layer A would be older than F as it is beneath layer F.

Therefore, this means your second choice, or the fossils in layer F are newer than the fossils in layer D, is correct.

Hope this helps!

A microtubule appears as a left-handed helix due to an approximately 0.9-nm stagger in the lateral contacts between adjacent pro
Olin [163]

Answer:

Th acceptable distance of tubulin monomers along a protofilament is : <u>A. 4nm</u>

Explanation:

MICROTUBULES are an important component of the cytoskeleton of eukaryotic cells. Its function is part of a structural role that helps define cell morphology, and also serves as an intracellular motor for some proteins such as kinesin and dynein.  

For the correct formation of the structures called microtubules to occur, a process called polymerization is required. In this process there is a head-to-tail junction in which the dimer junction between tubulines forms a structure called protofilaments and those protofilaments run along the microtubule. Then, the other process occurs in which, by lateral interactions between the structures mentioned above , the wall of The microtubule will be completed.
