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.

C. footprints from a dinosaur in mud that hardened
D. minerals replacing tissue in wood and hardening
Answer:
A. An insect getting stuck in tree sap that hardened
Explanation:
The answer is A because that is one of the ways to collect DNA samples for animals. The other way is digging for fossils.

As a body cell grows, the ratio of _______ to volume _________. Before it grows to large, a cell will divide into two ________ cells. So that each new cell receives its own genetic instructions, the cell ________ or copies, all of its DNA.
Answer: As a body cell grows, the ratio of SURFACE AREA to volume INCREASES. Before it grows to large, a cell will divide into two DAUGHTER cells. So that each new cell receives its own genetic instructions, the cell REPLICATES or copies, all of its DNA.
Explanation:
As a body cell grows, the ratio of surface area to volume decreases. Before it grows to large, a cell will divide into two daughter cells. So that each new cell receives its own genetic instructions, the cell replicates or copies, all of its DNA.
The volume of a growing cell increases at a larger pace than the surface area. Hence the ratio of the surface area to the volume of the cell keeps decreasing. At a certain point, the signal to divide is given and this leads to the division of the cell into two daughter cells.
Just before the division, the genetic material of the cell is replicated and other important biomolecules are synthesized before the final call can be made.

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.

Answer:
meiosis
Explanation:
Elements and compounds are pure substances that cannot be broken down physically into a simpler substance. A physical change doesn’t break the bonds between atoms of a substance or form new ones. Compounds can be broken down by a chemical change. A chemical change breaks chemical bonds and/or forms new ones between atoms of a substance. What simple substance would a compound break into? The basic elements that make it up! For example, if you passed a very strong electric current through water you’d break the chemical bonds in water and be left with oxygen and hydrogen. Which of the following is an example of a chemical change?
A
separating water into different glasses
B
breaking frozen ice cubes with a hammer
C
running an electric current through water
D
boiling water to evaporate it on a stove

Which of these factors is involved in earthquake formation?
Answer:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two blocks of rock or two plates are rubbing against each other, they stick a little. They don't just slide smoothly; the rocks catch on each other.

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.
