The ratio between the force of sliding friction and the normal force of an object is called _____.-rolling friction
-the drag
-the coefficient of friction
-the starting friction

Answers

Answer 1

Answer:

Answer;

The coefficient of friction

Explanation;

Friction is a force that opposes motion. Normal force on the other hand is a force that presses two surfaces together and is directed perpendicular to the contact surface; on a level surface. The magnitude of normal force is equal to the force of the object's weight but in the opposite direction.
The coefficient of friction shows the relationship between the force of friction between tow objects and the normal force between those objects.

Answer 2

Answer: The ratio between the force of sliding friction and the normal force of an object is called the coefficient of friction.

How is pillow lava evidence of
sea-floor spreading?

Answers

Pillow lava is evidence of sea-floor spreading because the lava comes up out of cracks at the mid-ocean ridge and becomes newly formed rock. The farther away you get from the mid-ocean ridge, the older the rock is.

A mutation changes the DNA sequence AAGCCTGGCAAT to the new sequence AAGCCTGCGCAAT. What kind of mutation has occurred? A. deletion B. insertion C. duplication D. substitution

Answers

A mutation that changes the DNA sequence AAGCCTGGCAAT to the new sequence AAGCCTGCGCAAT is B. insertion. There are different types of mutations that can change DNA sequences. Insertions are mutations when one or more nucleotides are inserted. The original sequence has 12 nucleotides. The new sequence has 13 nucleotides because 1 nucleotide is inserted in between the 7th and the 8th nucleotide. Since the nucleotide is inserted, the mutation that occurred is insertion.

What is the difference between a species and population

Answers

Species are all of one type...like Canis familiaris. A population is a group of the same species, like a pack of Canis familiaris. A community, however, would include all Canis whateveris, plus all the other different species. A community lives in the woods...all the different plants and animals.

This is a good question, I feel that a species can only consist of a specific type of organism. Example "dogs" and "wolves" species name is canus lupus and a dog's is canus familiarus. A population can consist of multiple species.

Provide 3 points of interest about translation of the cell.

Answers

In Biology, the process of translation is where proteins are created from cellular ribosomes. The process of translation is composed of three phases: Initiation, Elongation, and Termination.

During the Initiation, ribosomes assemble around the target mRNA and tRNA is attached at the start codon. tRNA then transfers amino acid to the tRNA of the next codon during the Elongation. While the ribosome creates the amino acid chain while moving to the next mRNA codon. During the Termination, ribosome releases polypeptide in the stop codon.

Explain the role of scientific investigation in the development of the Theory of Natural Selection.

Answers

The scientific investigation is the systematic approach of the scientists to answer the questions about the world. It is applied almost all of the theories including the Theory of Natural Selection. Darwin's theory of evolution is a result of scientific investigation. In this theory, they investigate by observing the distribution of species.

Final answer:

Scientific investigation is crucial in the development of the Theory of Natural Selection. This was illustrated by Charles Darwin and Alfred Russel Wallace in the 19th century, who used systematic observation, measurement, and experimentation to formulate the theory that diversity of life arose gradually through natural selection. A notable example is Darwin's research on finches in the Galapagos Islands.

Explanation:

The role of scientific investigation in the development of the Theory of Natural Selection is crucial. Scientific investigation involves the systematic observation, measurement, experiment, and the formation of theories or hypotheses, which are then tested.

In the 19th century, Charles Darwin and Alfred Russel Wallace independently devised the Theory of Natural Selection which proposed that the diversity of life arose through gradual changes in populations over time. They built this theory based on years of careful observation, note-taking, and hypothesis-testing - in essence, systematic scientific investigation.

For example, Darwin observed different variations of finches across the Galapagos Islands and made notes on their physical traits and habitats. Through rigorous analysis of this data, he eventually proposed that each species of finch adapted over generations to best suit its environment via the mechanism of natural selection.

So, scientific investigation played a fundamental role in the formulation and further development of this transformative biological theory.
