Answer:
cells consists of cytoplasm enclosed within a membrane, which contains many biomolecules such as protiens and nucleic acids.
A Domain
B Kingdom
C Genus
O D Species
Answer:
D Species
Explanation:
Living organisms have been organized into groups using the Kingdom to Species classification. Kingdom level represents the least specific while Species level represents the most specific. Prior to the discovery of DNA, classification of organisms has been based on structural similarities i.e. organisms that look similar are classified into the same species.
However, the discovery of DNA, put a stop to the erroneous classification of organisms based on structural similarities as there were many exceptions to this. Since members of the same species have a nearly identical DNA, it is used to divide its organisms based on DNA sequences
instead of structural similarities.
The index fossil is an example of evidence of unconformity. The statement given in the question if true.
Index fossils are the fossils used to define and identify the different geological periods. The fossils must have a short vertical range with a wide range of geographic distribution and the rapid evolutionary trends.
A fossil indicates the relative age of a rock in which it is found. Index fossils come from species that were widespread but existed for a short period of time.
An unconformity is a buried erosional surface which separates two rock masses or strata of different ages, indicating that the sediment deposition was not continuous. A geologic unconformity is when an older rock formation has been deformed or partially eroded before a younger rock layer, usually a sedimentary rock is laid down which results in mismatched rock layers.
Thus, index fossils can be used as an evidence of unconformity.

Big Ideas: All living things have certain traits in common: Cellular organization, the ability to reproduce, growth & development, energy use, homeostasis, response to their environment, and the ability to adapt. Living things will exhibit all of these traits
Explanation:
Answer:
I don't know exactly what you need but I give you an example so that you can create your samples through the Excel program, I hope it helps.
Just enter your sampling frame (the clients of which you have contact information) in the spreadsheet. Once you have a sampling frame (possible respondents) in Excel, you can easily select a random sample among them. For example, in your case that it is a work of biology and neceists three random samples here you can apply it with the following rules:
-Add a new column in the spreadsheet and name it "Random Number".
-In the first cell below your header row, type "= RAND ()".
-Press “Enter” and a random number will appear in the cell.
-Copy and paste the first cell in the other cells of the column.
-Once each row has a random number, organize the records from the "Random number" column.
-Then, select the first samples. In this way you will randomly choose from all samples.
