In the early 1700s, Linnaeus came up with a new system of classification of living things that eventually replaced the one that had been used since Aristotle developed it in ancient Greece about 2000 years earlier. Why was a change necessary? A new system was needed to include the new species that had evolved, since the original classification system was developed. So many new species were being discovered, it was impossible to arrange them all in a hierarchy based on relative complexity of species. A system based on differences in physical characteristics was no longer sufficient to describe all that was known about living things. There was no way in Aristotle's system to classify the microscopic organisms discovered after the development of the microscope.
Many biological systems classify the organism based on the cells, reproduction, simplicity and complexity. The discovery of the new species and arrangement based on the hierarchy led to the change.
What was the new classification system?Aristotle gave the most primitive biological hierarchical classification system that was replaced by the system of the Linnaeus. He gave the classification based on the taxonomy groups.
With time many new organisms and species were discovered that did not fit in Aristotle's classification system. Hence, with time new systems were established to classify the organism based on many new parameters.
Therefore, option A. new system was established to classify the new organism discovered.

The quantity, branching, and placement of the dendrites or projections that make up a nerve cell, collectively known as arborization, determine the structure of the nerve cell. Thus, option A is correct.
What is main role of nerve cell in nervous system?Their ability to communicate with their environment and other nerve cells or neurons, as well as their responsibilities in computation, are determined by this.
The basic building blocks of the brain and nervous system are neurons (also known as neurons or nerve cells).
The cells known as neurons are responsible for receiving sensory data from the outside world, sending commands to our muscles, and converting and relaying electrical signals at various points along the road.
Therefore, cells are long, with branches that help transmit signals quickly.

Phosphorus dose not travel through which of the following spheres Biosphere,lithosphere , geosphere , atmosphere?m
Answer:
The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.
The atmosphere does not play an important role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are solids at the symbolic ranges of temperature and pressure present on Earth.
Thus, the earths spheres like biosphere, Cryosphere and lithosphere are included in the phosphorus cycle but atmosphere is your answer.

S.J. Singer and Garth L. Nicolson first presented the fluid mosaic concept in 1972.
What is fluid mosaic model?The model still provides the best explanation for the structure and operations of the plasma membrane as they are understood today, despite some changes over time.
According to the fluid mosaic concept, the plasma membrane is made up of a variety of elements, including phospholipids, cholesterol, proteins, and carbohydrates, which give the membrane its fluid appearance. The thickness of plasma membranes varies from 5 to 10 nm.

The human immune virus cannot reproduce without host cells.
Human immune virusThe human immune virus is an RNA virus that only becomes active in human hosts.
When the virus gains access into a suitable host, it embeds its genome into that of the host and as such, the genetic machinery of the host is utilized to multiply the genome of the virus.
With time, the virus gradually takes over the host's genome system and breaks down their immune system, making them susceptible to diseases.

The repeating sequence of events in eukaryotes that involves cell growth and cell division is called the . (one word per blank)
Answer:cell cycle
Explanation:
The repeating sequence of events in eukaryotes that involves cell growth and cell division is called as cell cycle.
What is cell cycle?
A cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
The cell cycle can be thought of as the life cycle of a cell. In other words, it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a mother cell—and reproduction—division to make two new daughter cells.

Which of these organisms has an internal structure made of bone and cartilage?
A. Organism I
B. Organism Il
C. Organism Ill
D. Organism V
Answer:
im pretty sure its c
Explanation:
Organism Ill has an internal structure made of bone and cartilage.
What is Internal structure?The internal structures of an animal are essential to its survival. For example, inside their bodies, a lot of animals (including you!) have a heart. The heart works as a pump to move blood through the animal's blood vessels.
Blood vessels are like highways that travel to every inch of your body. The blood inside the vessels contains important chemicals that your body uses to grow and work, like nutrients, and hormones.
The stomach is an important internal structure because it's where an animal gets nutrients. First, the animal eats food, and then the stomach breaks that food down, sending the good nutrients to the blood and getting rid of everything else.
Therefore, Organism Ill has an internal structure made of bone and cartilage.

True or False: The west coast gets the most precipitation out of the entire United States
The statement "The west coast gets the most precipitation out of the entire United States" is definitely true.
Which part of the United States has the highest precipitation?The most precipitated part of the United States is found on some Hawaiian islands and coastal Alaska. They approximately get 460 inches of 11, 684 mL of rain each year.
The United States is generally present on a little bit high latitudes, so the west coasts are typically more wetter as compared to east coasts. This is because low-pressure systems moving up the east coasts bring that significantly result in higher precipitation on the western coasts.
