The correct answer is - the ocean animals deposited in its layers.
The sedimentary rock on the image is clearly an organic sedimentary rock because it contains fossils of marine animals. This type of sedimentary rocks form when sediments and organic matter come in contact, are merged, or rather naturally cemented so they are stuck together, and the end result is a sedimentary rock with organic matter involved in its composition. The organic sedimentary rocks are much more common in places where there was once a marine life, and much rarer with organic matter from terrestrial animals in it, though there are some rich deposits from that type in certain places as well.
The correct answer is stabilising selection. This is selection that favours an average trait value. It is thought that this sort of selection is very common as traits among most animals do not appear to change drastically over time. Stabilising selection selects against the extreme traits, and leads to a decrease in genetic diversity by favouring the average phenotypes.
Answer:
2 or 3
Explanation:
I believe it's 3, I could be wrong though.
Answer:
The distance between them is changing at the speed of 10.16 m/hr
Explanation:
Consider the sketch attached below.
The question is simply asking to calculate the resultant of the two velocities.
To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.
90 + 45 = 135°
from the cosine rule we have
=
+
- 2abcosθ
=
+
- 2 ×6×5×cos 135
= 103.426
c = 
c = 10.17 m/hr
