Answer: C.
Explanation:
Is the classification system of domains and kingdoms the only system that scientists have ever used to classify organisms?
No, the classification system of domains and kingdoms is not the only system that scientists have used to classify organisms.
What is a classification process?The classification of living organisms has been a continuous process since the time of Aristotle, and scientists have used various systems over time to classify organisms.
Prior to the current system, scientists used a five-kingdom classification system that classified organisms into Monera, Protista, Fungi, Plantae, and Animalia. However, advances in molecular biology and genetics led to the realization that this system did not accurately reflect the evolutionary relationships among organisms.
The current classification system, which is based on three domains - Archaea, Bacteria, and Eukarya - was proposed in the late 1970s and early 1980s by Carl Woese and his colleagues.

A 4 column table with 5 rows. First column is unlabeled with entries: Crust, uppercase mantle, Lower mantle, Outer core, Inner core. Second column is labeled Thickness in kilometers with entries: 30, 720, 2,171, 2,259, 1,221. Third column is labeled Density in grams per centimeters cubed, divided into Top and Bottom columns. Top entries are: 2.2, 3.4, 4.4, 9.9, 12.8. Bottom entries are 2.9, 4.4, 5.6, 12.2, 13.1. Fourth column is labeled Types of Rock Found with entries: Silicic rocks, Peridotite, Magnesium and silicon oxides, Iron plus oxygen, Iron plus oxygen.
Which conclusion is supported by information in the table?

Answer:
B
Explanation:
Every compound can be represented by a chemical formula. A chemical formula is the set of symbols showing the elements that make up a compound and their proportions. Water’s chemical formula is H_2 2 O. That means a molecule of water contains two atoms of hydrogen and one atom of oxygen chemically bonded. A molecule is a group of two or more atoms bonded together. Molecules can range in size from two to thousands of atoms. A molecule of a compound is the smallest unit of that compound. Every molecule of water has all the physical and chemical properties of water. That’s because every molecule of water is made of the same elements in the same proportions: two hydrogen atoms and one oxygen! Which of the following is a true statement?
A
Every molecule of the same compound will have different properties.
B
Every molecule of a compound has the same proportion of elements.
C
Molecules can be physically separated into smaller units of a compound.
D
Molecules cannot be represented by chemical formulae.
Answer: The answer is b!
Explanation:
B. Every molecule of a compound has the same proportion of elements.
What is a chemical compound?A chemical compound is a substance made up of two or more different elements that are chemically bonded together. The elements in a chemical compound are present in a specific ratio, and the properties of the compound are determined by the properties of its constituent elements and their arrangement.
Examples of chemical compounds include water (H2O), table salt (NaCl), and carbon dioxide (CO2). The chemical formula of a compound represents the types and number of atoms present in a single molecule of the compound. In the case of water, the chemical formula is H2O, indicating that it is made up of two hydrogen atoms and one oxygen atom.

A scientist observes two stars in the night sky through a telescope. Star A is white in color and relatively dim. The star’s estimated temperature is very high.
Star B is red in color and extremely bright. The star’s temperature is low compared with other stars.
Help the scientist classify the two stars.
Answer:
Star A is a Neutron Star while Star B is a Red Giant
Explanation: Neutron star is a very hot star, very small in size and hence dim and is white in color. A neutron star results after a massive star goes supernova. It is primarily composed of neutrons packed in a small boundary.
star B would be a red giant. This is because, a red giant star is red in color, is very big in size, and has a low temperature. A red giant star is a towards the end stage of a small to an average mass star.

A student at an exhibition looks at a model of Earth, as shown. The model is made using different colors to show water and land on the surface of Earth. The color green shows areas covered in land and blue shows areas covered in water. Each side of the model is shown.
The student learns that the water on Earth is stored in different forms. Water on Earth is broadly categorized into salt water and freshwater. The usability of water depends on the quantity available and its characteristics. The model shows the distribution of water on Earth in various reservoirs.
Question:The student claims there are large quantities of water immediately available for humans to drink on the surface of Earth. Is the claim given by the student correct? Use evidence from the graphs to describe why or why not.

Answer:
the claim given by the student is false. the diagram shows that 3% of the total water on earth is fresh water. All the other water would have to be filtered and made safe to drink.

Do you think that humans and humpback whales share a common evolutionary lineage?
Answer:
Yes!
Explanation:
Yes because when it comes to whales and humans we have a lot in common. They have different behaviors and languages within their own culture as humans do.They come in a lot of sizes and have different behaviors. Just like us and they are also mammals. While other sea creatures have gills.
Answer:
Scientists have used computer analysis to read evolution backward and reconstruct a large part of the genome of an 80-million-year-old mammal. This tiny shrewlike creature was the common ancestor of humans and other living mammals as diverse as horses, bats, tigers and whales.

Researchers have been studying how emissions from both volcanoes and human activities, such as the burning of fossil fuels, impact the atmosphere. Both types of emissions contribute to the total CO2 levels in the atmosphere. Graph 2 shows that atmospheric CO2 levels have been steadily increasing over time. This increase in CO2 levels has been linked to the increase in global surface temperatures.
Explain why the total mass of carbon must be decreasing in a different step of the slow carbon cycle based on the on the increase in atmospheric CO2.
