Geologists determine the
geological history of an area by
examining rock layers in geologic
columns. The diagram shows
three geologic columns from the
same region that have not been
overturned.
A.
Place an arrow at each rock
layer boundary to represent a
missing layer of rock in each
of the three columns.
Next part in pic
The sample columns have two missing layers as follows:
Column 1: Layers 3 and 8 are missing. Column 2: Layers 1 and 7 are missing. Column 3: Layers 1 and 5 are missing. What is geology?Geology is a term to refer to the specialized science that focuses on the study of the composition and internal and external structure of the surface of the planet Earth, and the processes by which it has evolved throughout geological time.
In the image 3 columns are shown showing various layers of the Earth, however, each of it has 2 missing layers. To know which layers were missing from each one, we must analyze them to establish what a column with complete layers would look like and then compare the 3 samples with the model to know which layers are missing.
According to the previous process, it can be inferred that the missing layers in each column are:
Column 1: Layers 3 and 8 are missing. Column 2: Layers 1 and 7 are missing. Column 3: Layers 1 and 5 are missing.Note: This question is incomplete because the graph is missing. Here is the graph.

A scientist carried out an experiment to follow the movement of carbon atoms within animal cells. To do this, the scientist added glucose with radioactively labeled carbon atoms to a culture of cells growing in a Petri dish.
After a certain amount of time had passed, the scientist tested parts of cells for radioactivity. Radioactivity was detected in various biomolecules, including DNA.
Which of the following statements best explains why radioactivity was detected in the DNA?
Choose 1 answer:
(Choice A)
The DNA was in close proximity to the radioactive glucose during its formation.
(Choice B)
Carbon atoms that were once in the radioactively labeled glucose were used to form DNA.
(Choice C)
The DNA was made up of radioactively labeled glucose subunits.
Carbon atoms that were once in the radioactively labeled glucose were used to form DNA - this statement best explains why radioactivity was detected in the DNA.
What is radioactivity in DNA?Radioactivity is known to induce tumors, chromosome lesions, and minisatellite length mutations.
Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions.
The radiation could damage the cell’s DNA, but the DNA repairs itself. The radiation could prevent the DNA from replicating correctly. The radiation could damage the DNA so badly that the cell dies.

The energy in glucose has to be converted to a usable form by the cells
which is why it is always converted to ATP( Adenosine triphosphate). The
energy supplied by ATP is then used to perform various activities in the

Explanation:
DNA and RNA are ______ that serve as templates that form proteins
Answer:
In the first step, the information in DNA is
transferred to a messenger RNA (mRNA)
molecule by way of a process called
transcription.... The mRNA sequence is
thus used as a template to assemble-in
order-the chain of amino acids that form a
protein.
A type of RNA that is called as ribonucleic acid type called as transfer RNA that is used for the production of the amino acid at a time and the protein assembly takes place at the ribosomes.
What is the role of DNA and RNA for the sake of protein synthesis ?
DNA are responsible for the providing out the code for the cell's activities and the RNA are responsible for providing out the service to make them proteins.
Each group of 3 bases in the mRNA constitutes a codon and each codon is specifying a particular type of amino acid. The mRNA sequence therefore used as a template to make the assembly in order of the chain of amino acids which form a protein.
It is found that in all biological cells , usually occurs in cytoplasm of cell though its production takes place in nucleus. Whereas DNA is providing the code for cell's activities and RNA is responsible for converting that code into proteins which carry various cellular functions.

If your observation had not been restricted to the tip of the onion root, how would the results be different?
The distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.
What is the cell cycle?The cell cycle is a series of well-defined steps in the life of a cell that begins with cell growth and end with its division.
The cell division has a series of steps that may be classified according to the phenomena that occur in these phases.
For example, chromosomes condense during the first stage of cell division (prophase), where they migrate to the equatorial plate at metaphase.
In conclusion, the distinguishing visible features of each stage of the cell cycle include chromosome condensation, mitotic spindle, equatorial plate and formation of two cells.

Energy flow in an ecosystem is best represented by _______.
explain how the information in this diagram indicates that an oxygen atom could bond covalently to two hydrogen atoms to form water
Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.
