Answer:
A) Red Light
B) Green Light
A) Blue Light
B) Cyan Light
Explanation:
I believe that you are overthinking this. White light is a combination of all the colors on the visible spectrum. This means that if you shine a white light through a red filter, it will only show the red light that is in the white light. There will be only red because the other colors of the spectrum are not visible due to the filter.
This rule applies to all of the filters.

Red blood cells transport oxygen to every cell in the body. This oxygen is needed to release energy stored in glucose molecules. Red blood cells also transport carbon dioxide, a waste product produced by cells, back to the lungs where it is exhaled. When a person exercises, his or her muscle cells consume more oxygen and produce more carbon dioxide. The body responds by increasing its breathing rate and heart rate to supply more oxygen-rich blood to the muscles and carry away more wastes. Explain how this is an example of maintaining homeostasis.

Module 3_Discussion In this module we discussed the Theory of Constraints. Looking at the recent Covid situation, how would you say the Theory of Constraints applied to the production of breathing masks in the United States? What did the U.S. government do to remove constraints when it came to vaccine production?
The Theory of Constraints addresses bottlenecks in mask production. The US government expedited vaccine development and production, increased funding, and secured essential supplies to remove constraints.
The Theory of Constraints (TOC) can be applied to the production of breathing masks in the United States by identifying and addressing the bottlenecks or constraints that hinder the production process. For example, during the early stages of the COVID-19 pandemic, there was a shortage of raw materials, manufacturing capacity, and distribution channels for masks. TOC would suggest focusing efforts on alleviating these constraints to increase mask production. This could involve sourcing additional raw materials, expanding manufacturing capabilities, optimizing production lines, and streamlining distribution logistics.
Regarding vaccine production, the U.S. government implemented several measures to remove constraints. They worked to expedite the regulatory approval process for vaccines, facilitating faster development and production. The government provided funding to vaccine manufacturers to expand their manufacturing capacity and ramp up production. They also invoked the Defense Production Act to secure essential supplies and equipment needed for vaccine production. These actions aimed to eliminate constraints such as limited production capacity, logistical challenges, and supply chain disruptions, allowing for a more efficient and accelerated vaccine production process.

The one physical trait that would most likely become more common in the population of native herbivores over time is longer necks.
Why the longer necks?This is because longer necks would allow the native herbivores to reach the higher-hanging leaves that the invasive species cannot reach. In natural selection, the traits that are most beneficial to an organism's survival and reproduction are the ones that are most likely to be passed on to the next generation.
In this case, the trait of having a longer neck would be beneficial to the native herbivores because it would allow them to reach the higher-hanging leaves that the invasive species cannot reach.
As a result, the native herbivores with longer necks would be more likely to survive and reproduce, and their offspring would also be more likely to have long necks. Over time, this would lead to an increase in the number of native herbivores with long necks in the population.

Fruit. Several plant species rely heavily on their fruits for seed distribution. Dehiscent fruits, like poppy capsules, usually include seeds that are spread directly from the fruits, which may still be attached to the plant.
The fruit only serves to spread its seeds. Fruit seeds need to be spread far from the parent plant so they can grow in a favourable environment with fewer competitions.
While some fruits can disseminate on their own thanks to internal systems, others need the assistance of wind, water, and animals. The structure, chemistry, and size of the seed are altered to aid in dissemination.

How might swarming locusts affect planted crops? how might the swarms affect local populations of humans and insect-eating birds?.
Swarming locusts can cause severe damage to planted crops. The swarms of locusts can have devastating effects on the vegetation, leading to a shortage of food for local populations of humans and insect-eating birds.
What is a locust?
Locusts are a type of grasshopper that can form massive swarms that travel long distances and cause extensive damage to vegetation. The reason locusts swarm is that when they get too crowded, they change their behavior and appearance, becoming more like each other and less like individuals. Swarming can increase their chances of survival in areas where food is scarce or where they face threats from predators.
When swarming locusts affect planted crops, they can consume everything in their path, destroying entire fields. In some cases, farmers may lose their entire harvest due to a locust infestation. This can lead to a food shortage in the area, affecting local populations of humans and animals that rely on the crops for food and income.
Insect-eating birds and other animals that feed on insects can also be affected by swarming locusts.
While some birds may benefit from the abundance of food, others that rely on other types of insects may suffer as the locusts consume their prey. The overall impact on local populations of insect-eating birds will depend on the species and the severity and duration of the locust infestation.

does this graph show an endothermic of exothermic reaction?
(WILL GIVE BRAINLIEST)
1. endothermic, because the products are at a lower energy state in the reactants
2. endothermic, because it takes a lot of energy to cause the reaction to occur
3. exothermic, because the products are at a lower energy state in the reactants
4. exothermic, because it takes a lot of energy to cause the reaction to occur
Answer:
3. exothermic, because the products are at a lower energy state in the reactants
Explanation:
It is also because the average enthalpy is negative.
\({ \boxed{ \triangle H = \triangle products - \triangle reactants}}\)
since products are at lower energy state, the ∆H will be negative. But the negative represents loss of heat hence exothermic reaction.
The graph shows an exothermic because the products are at a lower energy state in the case of reactants. So the correct option is (3).
What is an exothermic reaction?
The kind of reaction in which energy is released in the form of light energy or heat energy is called an exothermic reaction. So, an exothermic reaction means the transfer of energy into the surroundings and not taking energy from the surroundings thus it is different from an endothermic reaction.
In the case of an exothermic reaction, the change in enthalpy, i.e ΔH will be negative. Therefore, it can be deduced that the net amount of energy required for the initiation of an exothermic reaction is comparatively less than the net amount of energy that is released by the exothermic reaction.
The calorimeter is a device used to measure the heat produced as a result of a chemical reaction. In this case, the net heat energy flowing through the calorimeter will be equal to the negative of the total change km energy of the system.
Therefore the correct option is (3).

a change in allele frequencies in a population over time in response to environmental pressure is characteristic of all of these except:
is known as evolution. Evolution is a process that occurs over many generations and is driven by natural selection, which is the survival and reproduction of individuals with traits that are better suited to the environment.
In response to environmental pressure, such as changes in climate, food availability, or disease, populations can experience changes in allele frequencies over time. For example, a population of organisms may contain individuals with different alleles for a particular trait, such as eye color. If individuals with a certain eye color are more successful at surviving and reproducing in a given environment, then over time, the frequency of that allele will increase in the population.
This process is known as selection, and it leads to the evolution of populations over time. In the case of HPV and cervical cancer, changes in the environment, such as increased access to vaccines and screenings, can result in changes in the frequency of certain types of HPV in a population.

when elaine's hand accidently touched the hot stove, she quickly pulled it away. she didn't even have to think about it; moving her hand seemed to occur automatically. it is unlikely that this could have been possible without the effective operation of which nervous system?
The effective operation of the peripheral nervous system was likely responsible for Elaine quickly pulling her hand away from the hot stove.
The peripheral nervous system is part of the nervous system that lies outside of the brain and spinal cord and includes all of the nerves that control movement and sensation in the limbs and other parts of the body.
When Elaine's hand touched the hot stove, sensory receptors in her skin detected the painful stimulus and sent electrical signals along sensory nerves to the spinal cord. The spinal cord rapidly processed the incoming signals and transmitted a reflex response along motor nerves back to the muscles in Elaine's hand, causing it to pull away from the stove.
This rapid, automatic response is known as the spinal reflex and is a prime example of the peripheral nervous system's ability to control movement and sensation in a quick and efficient manner. This type of reflex response is particularly important for protecting the body from harm and allowing it to respond to environmental stimuli in real-time.

what adaptations enable plants to increase or decrease water loss? how might each affect transpiration?
Plants have developed numerous adaptations to cope with varying levels of water availability in their surroundings. The following are some examples of how plants can increase or decrease water loss and their impact on transpiration.
Some of these adaptations include the following:
1. Leaf area reduction and thickness: Plants can decrease their leaf area and thickness to minimize the amount of water lost during transpiration.
2. Leaf Orientation: Some plants have leaves that are oriented to avoid excessive sunlight, which can cause water loss through transpiration.
3. Stomata density and closure: The number and size of stomata on a plant's leaves may be reduced to decrease water loss. Stomata also close during times of water scarcity to conserve water.
4. Root adaptations: Plants can increase their root length and surface area, which helps them absorb more water from the soil.
5. Waxy Cuticle: A waxy cuticle on the leaf surface of some plants helps to retain water, reducing transpiration loss.
6. CAM Photosynthesis: In CAM plants, photosynthesis occurs at night when the temperature is cooler, allowing the plant to reduce water loss during the day.
In summary, plants have evolved several adaptations to reduce water loss and minimize the impact of transpiration. Leaf area and thickness reduction, leaf orientation, stomatal density and closure, root adaptations, a waxy cuticle, and CAM photosynthesis are among the adaptations that plants can utilize to minimize water loss.
Transpiration is a process by which plants lose water through their leaves as a result of evaporation. Adaptations in plants have evolved to minimize water loss while still maintaining the necessary processes of photosynthesis and respiration.
