Its is FALSE  because Bandwidth refers to a range of acceptable performance levels in instructional design. If a learner's performance falls within this range, they receive feedback or reinforcement.

In the context of instructional design, a bandwidth is a range of acceptable performance levels that are established before a learning task is performed. If a learner's performance falls within this range, they receive reinforcement or feedback, which can be positive or corrective.

In the scenario presented, the learner's score of 44 falls outside of the acceptable range of performance, which is between 48-52. Therefore, they would not receive reinforcement or feedback, including bandwidth KR (knowledge of results), as they did not meet the performance criteria.

It is important for learners to receive appropriate feedback and reinforcement when they meet or exceed the acceptable range of performance, as this can reinforce positive behaviors and motivate further learning.

However, in cases where performance falls below the acceptable range, feedback and reinforcement should focus on corrective measures to help the learner improve their performance in future tasks.

Body Tissues. Tissue is a group of cells that have similar structure and that function together as a unit.

Molecules used for growth and repair become part of the body, and molecules used for energy are lost as CO2 and H2O.

The two measures that allow us to make predictions about evolutionary changes in a population are the heritability of a trait and the strength of selection.

Heritability is a measure of the extent to which genetic factors contribute to the variation in a particular trait within a population.

This can be determined through breeding experiments and statistical analysis. Traits with higher heritability are more likely to be passed on to offspring and therefore are more likely to evolve in response to selection.

The strength of selection refers to the degree to which a particular trait affects an organism's survival or reproduction.

Strong selection pressures will favor individuals with advantageous traits, leading to the evolution of those traits over time.

By combining information on heritability and the strength of selection, we can make predictions about the direction and rate of evolutionary change within a population.

For example, if a trait has high heritability and confers a strong survival advantage, we can expect to see rapid evolution of that trait over relatively few generations.

Electrical activity in the human body interacts with electromagnetic waves outside the body to contribute to both eyesight and the sense of touch.

For eyesight, electromagnetic waves in the form of visible light enter the eye and interact with the specialized cells called photoreceptors located in the retina. When light waves reach the retina, they stimulate the photoreceptors, specifically the cones and rods. These photoreceptor cells convert the light energy into electrical signals through a process called phototransduction. The electrical signals are then transmitted through the optic nerve to the visual processing centers in the brain, where they are interpreted, resulting in the perception of vision.

Regarding the sense of touch, electromagnetic waves do not directly interact with the skin but rather with objects in the external environment. When you touch an object, pressure receptors in the skin called mechanoreceptors are stimulated. These mechanoreceptors convert the physical pressure applied to the skin into electrical signals, also known as action potentials. These electrical signals travel through sensory neurons to the somatosensory cortex in the brain, which processes and interprets the signals, allowing you to perceive the sense of touch.

In summary, electromagnetic waves in the form of visible light interact with photoreceptors in the eye, converting light energy into electrical signals for vision. For touch, electromagnetic waves indirectly interact by stimulating mechanoreceptors in the skin, which then generate electrical signals that are transmitted to the brain for the perception of touch.

The answer is Cytokine Storm

Explanation:

a) When a carrot is submerged in a diluted solution, water will osmosis into the carrot cells. As a result, the cells will become turgid and the carrot's mass will rise.

b) The carrot's inability to alter in mass when submerged in a 0.4 mol/dm3 solution shows that the solute concentration—which includes salts and sugars—within the carrot cells is also 0.4 mol/dm3. There is no net movement of water into or out of the cells at this concentration.

c) This indicates that the carrot and the 0.4 mol/dm3 solution have come to an equilibrium. At this concentration, the passage of water into and out of the cells is balanced, and there is no net gain or loss of water.

d) If the carrot is submerged in a concentrated solution, water will osmotically escape from the cells, plasmolyzing them. The mass of the carrot will shrink as a result.

Answer: Biomagnification refers to the process by which the concentration of a contaminant increases as you move to higher trophic levels in a food chain or food web. In other words, as organisms consume other organisms, the contaminants present in the prey accumulate and become more concentrated in the bodies of the predators.

To understand this process, let's consider an example involving a water ecosystem. Suppose a pollutant is released into the water, such as a pesticide or heavy metal. The primary producers, such as algae or aquatic plants, absorb small amounts of the contaminant from the water. As herbivorous organisms consume these primary producers, they ingest the contaminants along with their food.

Since the contaminant is not easily broken down or eliminated from the organisms' bodies, it accumulates over time. As a result, the concentration of the contaminant becomes higher in the herbivores than in the primary producers. Now, when carnivorous organisms consume the herbivores, they not only accumulate the contaminant from their own food but also from all the prey they have consumed. This leads to an even higher concentration of the contaminant in the carnivores.

Therefore, biomagnification describes the phenomenon where the concentration of a contaminant increases significantly as you move up the food chain or trophic levels. The highest concentration of contaminants is often found in top predators, such as large fish, birds of prey, or mammals, which can have adverse effects on their health and reproductive capabilities.

It's important to note that biomagnification primarily occurs for persistent and non-biodegradable contaminants that cannot be easily metabolized or excreted by organisms. These contaminants are often lipophilic (fat-soluble), which allows them to accumulate in fatty tissues and remain in the organism's body for long periods, leading to biomagnification.

The conversion of 8 H₂O molecules to 2 H₂O molecules is a chemical change that occurs through a dehydration or condensation reaction. This process involves the removal of water molecules to form a larger molecule and requires energy to occur.

This is a reaction that occurs between two molecules, and results in the formation of a single, larger molecule, while releasing a small molecule, usually water. In this case, the small molecule is water (H₂O), hence the name dehydration or condensation reaction.
During this reaction, the 8 H₂O molecules combine to form 4 H₂O molecules. This reaction is often used in the laboratory to create polymers from monomers. It can also be used to produce certain biomolecules such as carbohydrates, proteins, and nucleic acids, as well as other chemical compounds.
In order to carry out this reaction, energy is required. The reaction occurs in several steps and involves the removal of water molecules from the original 8 H₂O molecules, forming a new, larger molecule. The reaction is reversible, which means that it can be carried out in both directions, depending on the conditions and reactants involved. Thus, the conversion of 8 H₂O molecules to 2 H₂O molecules is a chemical change that can occur through a process known as dehydration or condensation reaction.

One of the most significant and intriguing aspects of our planet, the seas currently make up around 71% of its surface and are home to innumerable plant and animal species. There are four processes that can be used to explain how the oceans came to be during Earth's early history.

The origin of the oceans during Earth's early history can be explained in four steps.

Step 1: When the early Earth was forming some 4.6 billion years ago, there were no oceans and it was a hot, dry region.

Step 2: As the Earth cooled, water vapour emitted by volcanoes and other natural sources began to condense onto the surface of the planet as liquid water.

Step 3: Eventually, the first seas were created when this liquid water gathered in low-lying locations. Scientists disagree on the precise timing and method of ocean formation, although it most likely took place between 3.8 and 4 billion years ago.

Step 4: After the seas developed, they significantly influenced the climate, chemistry, and life of the early Earth. They functioned as a habitat for the first living things, a source of nutrients and minerals for the planet's ecosystems, and helped control the temperature and carbon dioxide levels in the atmosphere.
