Answer:
D. Layers with similar fossils
Explanation:
Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle. This principle states that in a horizontal unperturbed rocky sequence, the oldest layers or stratum are located in the bottom, while the newest ones are more superficially located. Sediments can be incrusted in horizontal layers or stratum. Fossils that are incrusted on these layers represent different ages of the stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.
Some geological principles allow us to date, relatively, the age of different geological events in the past.
Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.
In this sense, those layers or stratum that exhibit the same fossils are believed to be the same age-old.

The ages of 7 trumpet players in a band are 13, 12, 11, 12, 11, 10 and 12. What type of graph would
be appropriate for comparing the ages of these trumpet players?
What kind of bar graph would this be
A. Table B.pie/circle graph C .Bar graph D. line graph
The graph that would be appropriate for comparing the ages of these trumpet players is the Bar graph. So, the correct option is C.
What is the Bar graph?A bar graph can be defined as a chart or a graphical representation of data, quantities, or numbers using bars or strips.
Bar graphs are used to compare things between different groups or to track changes over time. Pie charts can be used to show percentages of a whole and represent percentages at a set point in time. It does not reveal the changes over time. Line graphs are used to compare certain ups and downs at a specific pace.
Therefore, the graph that would be appropriate for comparing the ages of these trumpet players is the Bar graph.

Answer:
its A. Increased sewage system failures
Explanation:
When people fail to conserve water, the following will occur: increased sewage system failures, as in Option A, because water conservation should be done in order to get an equal amount of water everywhere..
What is the significance of the water loss?Water is the most important component of life because it is used in almost all processes, and animals and plants contain it for cellular structures, functions, and so on. When water is lost in a river or polluted, life forms suffer and water loss would lead to a shortage of water and a shortage of life forms as they become extinct, and that would lead to a disruption in the ecosystem.
Hence, when people fail to conserve water, the following will occur: increased sewage system failures, as in Option A, because water conservation should be done in order to get an equal amount of water everywhere.

B: it helps them study the life cycle phases of stars.
C: both A and B
D: neither A nor B
They may group stars depending on brightness and temperature, which aids in the classification of stars. Thus, option A is correct.
What is Hertzsprung-Russell (H-R) diagram?An essential astronomy tool for comprehending how stars change over time is the H-R diagram.
HR diagrams are useful because they provide crucial details about the stars that are plotted on them.
Astronomers can estimate a number of significant stellar parameters, such as diameter, mass, age, and evolutionary stage, after creating an HR diagram for a collection of stars.
The graphic illustrates their relationships to or distinctions from similar stars. Scientists can forecast a star's evolutionary course and future energy output based on where it sits on the map.

Suppose you are given an unknown sample of a grayish,shiny metal,suggest two tests or measurements that would help you determine whether or not the metal is iron
Answer:
Explanation:
I hope this isn't too late.
The two tests or measurements that would help you determine whether or not the metal is iron are as follows:
Rusting through oxidation.Magnetization with the help of a magnet. What are the properties of Metal?The properties of the metal are as follows:
Metals are good conductors of heat and electricity.They are malleable, ductile, lustrous, and sonorous.They generally possess high densities, tensile strength, and high melting points. They are generally hard as compared to other elements.Rusting is a process through which an external layer of iron is exposed to a reddish brown appearance due to the reaction of iron and oxygen in the presence of water or atmospheric moisture.
Magnetization is a method that utilizes a magnet and tries to attract the iron. If it successfully attracts your sample, it is most probably an iron.

What is the mass of an atom with seven protons seven neutrons and eight electrons
Answer:
The atom is a nitrogen atom and the mass of the atom is 14.0067 u.
An atom with seven protons, seven neutrons, and eight electrons has a mass of 14 g.
What is an atom?Atoms are made up of protons, neutrons, and electrons. Each element has an atomic number that corresponds to the number of protons in its nucleus.
Given that,
Number of protons is 7.Number of neutrons is 7.Number of electrons is 8.The mass number of an atom is the sum of its atomic number and neutron number.
Mass number = number of neutron + atomic number
As the atomic number of an element will be equal to the number of protons of such elements, so in this case,
Mass number = 7 + 7Mass number = 14 gThus, the mass of an atom with seven protons, seven neutrons, and eight electrons is 14 g
