Oldest to youngest
Sandstone with trilobite → limestone with crinoid → shale with ammonite → conglomerate
According to the rule of superposition, rock strata (layers) that are the furthest from the ground's surface are the oldest (formed earliest) and those that are the nearest to it are the youngest (formed most recently).
<h3>What is a Rock ?</h3>
A rock is a dense mass of mineral grains that have grown or been cemented together over time. There are big rocks and little rocks. Pebbles are little rocks. One or more minerals can be found in every rock.
- According to how they were formed, rocks are categorised by geologists (those who study rocks and minerals).
- Among the physical characteristics of rocks are density, porosity, and permeability. Elastic modulus, Poisson's ratio, and rock strength are the primary characteristics of rocks in terms of mechanics.

Answer:
The part of the microscope that is used to make small adjustments in the image of an object is the fine adjustment.
Explanation:
In the optical microscope, the fine adjustment knob allows precise focusing of the sample being studied.  This means making minimal adjustments in order to better observe the microscopic image.
After the initial focusing with the coarse adjustment knob, with the fine adjustment it is possible to highlight the details that require more attention, as well as the refringency of the sample, if it exists.
The other options are not correct because:
<em>     A. </em><em><u>Eyepiece</u></em><em>  is the lens that receives the image from the objective lens, that has contact with the eyes of the observer.</em>
<em>     C. </em><em><u>Coarse Adjustment  </u></em><em>is the rough magnification, used for the initial approximation of the image.</em>
<em>     D. </em><em><u>Objective lens</u></em><em> enlarges and defines the image of the sample on the slide.</em>
 
        
             
        
        
        
Answer: The nucleas contains the majority of the cell's genetic material. This material is organized as DNA molecules, along with a variety of proteins, to form chromosomes.
 
        
                    
             
        
        
        
The purpose of the digestive system is to break down food into simple molecules that the cells of the body can use. 
Food is broken down  into its simplest units called monomers. Proteins are broken down into amino acids, fats are broken down into fatty acids and glycerol while carbohydrates are broken down into glucose units.
Glucose is taken in by the cells of the body and through the process of cellular respiration  is used to produce the ATP, the form of energy that cells use. Cellular respiration is the process by which cells use glucose to produce energy to power their functions.
