A hypothesis is a statement made by a scientist to explain a set of observations or answer a particular question. When scientists have sufficient data to support their hypothesis, they develop it into a scientific theory.

An explanation can only become a scientific theory if it meets a variety of criteria. It must be testable, falsifiable, have evidence to support it, and be consistent with existing research. What constitutes as a scientific theory?

A scientific theory is an explanation of an aspect of the natural world based on empirical data, tested and confirmed through the scientific method. Scientific theories are a compilation of observations and evidence that have been meticulously analyzed and have withstood the test of time. They are supported by a large body of evidence, providing a comprehensive and complete explanation of phenomena. It's worth noting that while a hypothesis can be tested with an experiment, it can't be proven correct. When a hypothesis has been rigorously tested and is generally accepted as an explanation for a phenomenon, it can be elevated to the level of scientific theory. The fossil evidence collected by the scientist in the scenario is merely supporting evidence, not conclusive. The scientist needs to gather more empirical data and test her hypothesis before it can be considered a scientific theory.

Thus, her hypothesis cannot become a scientific theory at this point as it needs further testing and evidence to support it.

Answer:

D

Explanation:

It allows only certain molecules to pass through

Answer:D

Explanation:

The integration value of 2 for the 1H NMR signal corresponding to the hydrogen atoms at position C indicates that there are two hydrogen atoms at that specific position.

In 1H NMR spectroscopy, the integration value represents the relative abundance or number of hydrogen atoms that contribute to a particular signal. It is obtained by measuring the area under the peak in the NMR spectrum.

In this case, the presence of an integration value of 2 suggests that there are two equivalent hydrogen atoms at position C in the molecule being analyzed. The value of 2 indicates that the intensity of the signal corresponding to these hydrogen atoms is twice as strong as the intensity of other signals in the spectrum.

The integration value is a useful parameter in NMR analysis as it provides information about the relative ratios of hydrogen atoms in a molecule, aiding in the determination of molecular structure and connectivity.

Zoology and ecology

Explanation:

Answer:

Environmental science is an interdisciplinary academic field that integrates physical, biological, and information sciences (including ecology, biology, physics, chemistry, plant science, zoology, mineralogy, oceanography, limnology, soil science, geology, and physical geography, and atmospheric science) to the study of the environment, and the solution of environmental problems.

Explanation:

The process of continued divergence in this scenario is called reinforcement.

Natural selection works to prevent hybridization between divergent populations through a process known as reinforcement, which leads to the emergence of interbreeding barriers and greater population divergence. In this instance, the environmental change has made it possible for the two previously separated populations to interact once more. However, the hybrid offspring are less likely to survive, which encourages selection against hybridization and the development of novel mating rituals, leading to the populations' continued divergence.

Understanding population dynamics necessitates being aware of the many influences that dispersal, productivity, and survival have on population growth. This is crucial for the preservation of tiny, recently established populations since stochastic births and deaths could have a negative impact on their growth or possibly cause them to go extinct.

Answer:

The depth of the ocean at that point is approximately 3,750 meters.

Explanation:

To calculate the depth of the ocean at a particular point using sonar, we need to know the time it takes for the sound wave to travel from the ship to the bottom of the ocean and back to the ship, as well as the speed of sound in water.

The speed of sound in water is approximately 1,500 meters per second (m/s).

If the sonar signal took 5 seconds to return to the ship, then the total time for the sound wave to travel from the ship to the bottom of the ocean and back to the ship is twice that, or 10 seconds.

We can use the formula:

Depth = (Speed of sound in water x Time) / 2

Plugging in the values we know, we get:

Depth = (1,500 m/s x 5 s) / 2

Depth = 7,500 meters / 2

Depth = 3,750 meters

The pulmonary circuit is responsible for carrying deoxygenated blood from the heart to the lungs for oxygenation and removal of carbon dioxide.

One advantage of having a low blood pressure in the pulmonary circuit is that it allows for a slower flow of blood through the pulmonary capillaries. This slower flow allows for more time for gas exchange to occur between the blood and the air in the lungs. Additionally, a low blood pressure in the pulmonary circuit helps prevent fluid accumulation in the alveolar walls and lumens, which could interfere with gas exchange.

Lastly, the hydrostatic pressure in the pulmonary capillaries overrides oncotic pressure, allowing for almost complete absorption of fluids.

The Golgi complex is the organelle that is often associated with defects in transport from compartment to compartment, resulting in poor sorting of protein components within the cell

The Golgi complex is an essential membrane-bound organelle in eukaryotic cells. It functions as a sorting and packaging center that modifies, sorts, and distributes lipids and proteins into vesicles for delivery to their final destination.

The Golgi complex consists of a series of flattened membranous sacs called cisternae stacked on top of one another. Each cisterna is a compartment that performs a distinct processing and modification function on the proteins and lipids passing through the Golgi complex. The Golgi complex is responsible for modifying and processing newly synthesized proteins by attaching carbohydrate or other molecular groups to them, among other functions.

In some genetic disorders, the Golgi complex is impacted, resulting in a defect in transport from compartment to compartment, leading to poor sorting of protein components within the cell.

As a result, the Golgi complex's functions, such as processing and modification of proteins and lipids, are negatively impacted, leading to a variety of symptoms.

Examples of diseases caused by Golgi complex dysfunction include Salla disease and congenital disorder of glycosylation.
