The most characteristic feature of clastic sedimentary rocks is "stratification".
<u>Answer:</u> Option A
<u>Explanation:</u>
"Stratification" is an essential characteristic of the sedimentary rocks take place in an igneous rock produced at the surface of the Earth naturally due to volcanic fragmental deposits and flows of lava. It defines the pattern in which sediment layers are layered over each other and may occur on a scale of hundreds of meters, even down to sub-millimeter.
It also results from variations in texture or composition during deposition. Delays in deposition may also permit for variations to the older deposits before coverage given by new sediments. This mechanism in sedimentary rocks change in both, the degree of prominence and in structure details.
Answer: The x-axis has mother bird and the y-axis has chicks
Explanation:
The researchers studying the relationship between the number of eggs which is laid by the birds and the number of chicks which is surviving at the end of the year.
The researchers will make a graph between these two factors. One is eggs laid and the number of chicks that survived till the year last.
This will help to known of the proportion of the chicks which survived on an average.
<span>Answer D is not correct, as gymnosprems are used widely for consumer goods such as lumber, soap, and nail polish.
Answer C is not correct event though wheat and corn are two of the main foods supplied to people in the world.
Answer B is a very subjective question, because some people argue that selective breeding helps agriculture, while others do not.
The correct answer is A. The green revolution was a period of scientific discoveries that lead to an increase in the supply of food worldwide.</span>
As the earth has active tectonics we know that rocks are recycled and the oldest rocks may therefore just be the oldest rocks that have not been recycled yet. We know the true age of the earth by looking at radioactive isotopes of things like spacedust and meteors that formed at the same time as the earth as they have not been affected by the tectonic process of recycling here on Earth.
Answer:
The correct answer is - they lack a nucleus, DNA, and organelles like the endoplasmic reticulum or mitochondria
Explanation:
Red blood cells are considered as the cells, carry oxygen with the help of hemoglobin protein present in it to the various parts of the body from the lungs and carry CO2 back to the lungs.
These cells are different from the normal cell as they do not participate in the protein synthesis due to the fact that they lack various cell organelle and cell components required. Nucleus and DNA are major components or organelle missing from these cells. In addition to these two, endoplasmic reticulum and mitochondria also missing from RBCs.
