The order of organisms that they would find in the layers of these sedimentary rocks is; Oldest organisms are at the bottom and the newest organism is in the top-most layer of the sedimentary rocks.
Sedimentary rocks are rocks that are made by the deposition and compression of other rocks or pieces of organic matter (dead plants and animals). According to the law of superposition which states that in a sequence of undisturbed sedimentary layers, the youngest layer is always at the top while the oldest layer is always at the bottom of the sequence. From the question, the organisms are components of the rocks. The oldest organisms will be found at the bottom layer of the sedimentary rocks while the newest organisms are in the topmost layer of the sedimentary rocks.
Scientists and engineers actively seek evidence to test their ideas — even if the test is difficult. The reason behind is the importance of asking questions based on observations to find more information about the natural effects and proposals. From there, it is ought to determine expected results based on testing, evidence resulting from that experiment will allow testers to find out the solution they are looking for.

The migrating group of Danaus plexippus, or Monarch butterflies, exemplifies a population, representing a collection of individuals of the same species in a specific geographic area capable of interbreeding.
The migrating group of Danaus plexippus, or Monarch butterflies, represents an example of a population.
A population, in ecological terms, refers to a group of individuals of the same species living in the same geographical area and capable of interbreeding.
In this case, the Monarch butterflies gather in clusters and migrate to a specific region in Mexico during the fall. While the term "population" focuses on a single species, it doesn't consider the interactions with other species or the physical environment.
In contrast:
- An ecosystem encompasses both living organisms and their physical environment.
- A community includes all the different species living in a particular area and their interactions.
- A biome refers to a large geographical area with specific climate and vegetation characteristics, encompassing multiple ecosystems and communities.
So, the Monarch butterflies migrating in clusters represent a population within the broader context of ecosystems, communities, and biomes.

Lipids are used by cells for energy storage, forming biological membranes, and serving as chemical messengers with different types of lipids like triglycerides, phospholipids and steroids serving different functions.
Lipids can be used by cells to store energy, form biological membranes, and serve as chemical messengers. Lipids are a group of fats and fat-like substances that are important parts of the cells and sources of energy. Lipids are used in the body for several functions including energy storage, insulation, and cellular communication. For example, triglycerides, a type of lipid, act as an important energy source when glucose levels are low. Phospholipids create the biological membranes, providing a barrier and enabling control of the substance passage in-and-out of the cells. Steroids, another type of lipids, serve as chemical messengers in the body, with cholesterol and hormones being examples of such steroids.
