The following is NOT of the major biogeochemical cycles D.Phosphorus cycle is D.Phosphorus cycle.
What is the difference between Carbon cycle and Phosphorus cycle?The major distinction among carbon and phosphorus cycle is that carbon cycle interacts with the environment while phosphorus cycle does now no longer engage with the environment. Therefore, the carbon cycle is a sort of gaseous biking while the phosphorus biking is a sort of sedimentary rocks.
As in comparison to nitrates & different macro elements, decomposers take longer time to decompose any lifeless biota into phosphates. Decomposers are organisms mainly a soil bacterium, fungus, or invertebrate, that decompose natural material. These are the motives for phosphorus cycle being the slowest biogeochemical cycle.

Answer:
(Q1: B)
(Q2:B)
(Q3:C)
(Q4:D)
(Q5:B)
Explanation:
Question 1:
A consensus hears all voices in a group and goes with the common "majority rule" and B shows this in clear detail.
Question 2:
They both have different skill sets but we can remove option A because all fossils are handled the same way. We can remove D because it doesn't make sense for the question which leaves us with C and B. This makes us know that the answer is B because it makes the most sense for the question.
Question 3:
An anthropologist is someone who specializes in the study of human societies and cultures and their development and an archaeologist is someone who digs up fossils. The only answer that makes sense here is C because the archaeologist can uncover the tools and where they made marks in the rock while an anthropologist can use those to discover what civilization it was and how those tools were used.
Question 4:
In the context of this question we can decide that the only relevant answer is D because it would watch over a period of time that could show climate change while the others are just simple facts that can be uncovered about the daily life of these insects.
Question 5:
The steps that can be taken to fix coral bleaching are to reduce stressors, such as sedimentation and pollution, and limiting climate change. This is because the main things that cause the coral to become bleached are changes in the temperature and salinity of the water. By polluting the ocean we change the chemical formula of the water and therefore affect the coral and the climate change heats the ocean to temperatures that the coral can't or will not be able to withstand.

What is a scientific theory? What is a hypothesis? How are they similar? How do they differ?
Answer: Scientific theories can be backed up with evidence/data (the evidence that backs the theory isn't common knowledge to everyone yet), while a hypothesis is just an educated guess, meaning that you are making a prediction based on something already known.
They are both similar in the sense that they are questions that are answered by facts, but theories are answered with factual evidence rather than factual reasoning (hypothesis).

Suppose that you are in charge of designing a fracking job site. Which of these locations would be most ideal for the site?
Answer:
B. On a flat, vacant plot in the outskirts of the city
Explanation:
Fracking, also known as hydraulic fracturing is a drilling method used in the oil and gas industry of most countries. It is the process whereby natural gas and petroleum is extracted from deep down the Earth. A crack is made in the rock layers, followed by the injection of a liquid called fracking liquid, which is usually water, at a very high pressure.
The process of fracking has serious environmental side effects e.g. release of harmful gases, noise pollution, water contamination etc. and hence, when choosing a fracking site, environment's sustainability and safety of people should be taken into account. This is why a fracking site cannot be designed in a residential city or around a neighborhood. The site should rather be designed in a location where it would pose a minimal environmental threat to the people e.g flat, vacant plot in the outskirts of the city

The Amish populations in the United States began with relatively few individuals and have not recruited many newcomers to the population. Today, these Amish populations exhibit a much higher incidence of polydactyly (possessing extra digits) than other American populations. Which mechanism of evolution is likely responsible for this phenomenon
Answer: The founder effect
Explanation: The high incidence of polydactyl prevalent among the Amish population could be attributed to the a case of genetic drift called the founder effect. The founder effect occurs when a small population consisting of few people separate from a much large population, just like the Amish population separating from the larger American community. Due to the few composition or small size of the population, the genetic impact or influence on members of the population is usually higher than the effect on the larger population and leading to more rapid spread. The relatively small individuals which make up the Amish population compared to the larger American community is the reason why polydactyl hmis prevent within them and since theere are no newcomers, the trend will likely continue.

In humans, the quadriceps muscle is a skeletal leg muscle under voluntary control. As such, it contracts in response to signals from the motor cortex in the cerebrum. If such a muscle contracts involuntarily, that indicates:
Answer:
The correct answer is - operation of reflex arc.
Explanation:
The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.
Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.
In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.
Thus, the correct answer is - operation of reflex arc.

briefly outline how cell theory has developed over the past 400 years
Explanation:
The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology. The idea predates other great paradigms of biology including Darwin’s theory of evolution (1859), Mendel’s laws of inheritance (1865), and the establishment of comparative biochemistry (1940).
First Cells Seen in Cork
While the invention of the telescope made the Cosmos accessible to human observation, the microsope opened up smaller worlds, showing what living forms were composed of. The cell was first discovered and named by Robert Hooke in 1665. He remarked that it looked strangely similar to cellula or small rooms which monks inhabited, thus deriving the name. However what Hooke actually saw was the dead cell walls of plant cells (cork) as it appeared under the microscope. Hooke’s description of these cells was published in Micrographia. The cell walls observed by Hooke gave no indication of the nucleus and other organelles found in most living cells. The first man to witness a live cell under a microscope was Anton van Leeuwenhoek, who in 1674 described the algae Spirogyra. Van Leeuwenhoek probably also saw bacteria
The cell theory, states that all organisms are composed of similar units of organization, called cells.
What is cell theory?The concept of cell theory was in 1839 by Schleiden & Schwann which leads the foundation of modern biology. Cell theory states that every cell is generated from another preexisting cell.

Schleiden & Schwann propose every organism is composed of the cell, which is the basic unit of life and each cell comes from the preexisting cell, and each cell produces a progeny which is similar to its parent cell.
Therefore, cell theory states the existence of the cell in the organism.

OmRNA is made in small quantities in infrequent batches.
O mRNA is made in large quantities in infrequent batches.
O mRNA is made in small quantities in frequent batches.
Answer:
O mRNA is made in small quantities in infrequent batches.
Explanation:
mRNA is made in small quantities in infrequent batches because the affinity of positive transcription is lower and affinity of negative transcription is higher which is responsible for production of mRNA from DNA molecule. Transcription is a process in which the information that is present in DNA molecule is copied to new mRNA molecule. Positive transcription factor is a promoter which promotes the initiation of transcription in order to enable RNA polymerase while negative transcription factor is a repressor protein.
