Answer:
Plants, animals, factories.
Explanation:
Plants and animals are living organisms that undergoes aerobic respiration that takes in Oxygen and released carbon dioxide.
Do not be mislead that plants do not give out CO2. During the night, when rate of photosynthesis is slower than rate of respiration, CO2 is released to the atmosphere and acts as a source of CO2.
Animals can only respirate and not photosynthesize. Hence, it is definitely a source of CO2
Factories are sources of CO2 assuming that their operations releases CO2 as by-product which is a very probable event for most factory operations.
Sunlight is a abiotic factor that does not cause CO2 to be released on its own to act as a source of CO2 in the atmosphere.
Plants, animals, and factories are sources of carbon dioxide in the atmosphere.
Explanation:Plants, animals, and factories are significant sources of carbon dioxide emissions into the Earth's atmosphere. Plants play a dual role in the carbon cycle. During photosynthesis, they absorb CO2 and convert it into oxygen (O2) and organic carbon compounds, helping regulate atmospheric CO2 levels. However, when plants decay or burn, they release CO2 back into the atmosphere.
Animals, through respiration, release CO2 as a byproduct of metabolism. This carbon comes from the food they consume, and when they exhale, it contributes to atmospheric CO2 levels. Factories, particularly those burning fossil fuels for energy and industrial processes, release substantial amounts of CO2 as a result of combustion. These human activities significantly impact global carbon levels and contribute to climate change and global warming. Sustainable practices and reduced emissions are critical to mitigate these effects.

Jonathon tests four people that were present during a shooting incidence. He notes that there is gunshot residue on all but two of the people, the victim
and another person. What might he conclude about the person with no gunshot residue on his hands or clothing?
O A. The person was next to the shooter.
OB. The person was the shooter.
Oc.
The person was not the intended victim.
OD.
The person was not beside the shooter.
O E.
The person struggled with the shooter.
Final answer:
Given the absence of gunshot residue on one individual besides the victim at the scene, the most likely conclusion is that this person was not beside the shooter when the gun was fired. D. The person was not beside the shooter is correct.
Explanation:
When Jonathan discovers that gunshot residue is absent on one of the people at the shooting scene, it suggests a few possibilities, but with the options provided, one stands out. Given that the victim also didn't have gunshot residue, it's reasonable to infer that someone not involved with the gunfire itself would likely be free from residue. Therefore, the absence of residue on another individual could indicate that they were not in proximity to the shooter when the gun was discharged. Interpreting evidence requires careful thought and consideration of all potential scenarios.
The most fitting conclusion from the given options is that this person was not beside the shooter. This would be consistent with the expectation that someone standing close to the shooter might have residue on them from being in close vicinity to the fired weapon. Hence, the correct option is:
OD. The person was not beside the shooter.

Why did mosquitoes develop resistance to DDT?
A. Because it was killing them so they had to do something!
B. The government reduced their use of DDT after the book Silent Spring and the mosquitoes used the time to develop defenses against DDT.
C. The ones which had a genetic variant that was tolerant of the DDT survived and reproduced.
D. The nuclear DNA mutated and some individual mosquitoes developed resistance.
Mosquitoes developed DDT resistance through natural selection, where mosquitoes with a genetic variation that allowed for DDT tolerance survived and reproduced, passing these advantageous genes to their offspring. Therefore, the correct answer is option C. The ones which had a genetic variant that was tolerant of the DDT survived and reproduced.
The development of DDT resistance in mosquitoes is a clear example of natural selection at work. The correct answer to why mosquitoes developed resistance to DDT is C. The process works as follows: when DDT was widely used, it killed off a large proportion of the mosquito population; however, within any population, there is genetic variation. During this selection process, only mosquitoes with a genetic variant tolerant of the insecticide survived and passed on their genes to the next generation. Over time, these resistant individuals became more prevalent. This explanation is rooted in biology, specifically genetics and evolution.
To elaborate, female mosquitoes did not purposely choose to mate with resistant male mosquitoes to ensure fit offspring. Resistance developed because of a natural genetic variation that provided some mosquitoes with a survival advantage in a DDT-rich environment. Similar resistance patterns have been observed in Plasmodium, the protozoan that causes malaria, which has become resistant to anti-malarial medicines due to over-prescription and subsequent selection pressures. The outcome of such adaptations is an increase in the proportion of individuals with the advantageous traits in a population.
What is the function of heart valves?
They return blood to the heart.
They force blood to flow out of the heart.
They regulate the heart rhythm.
They prevent blood from flowing backwards.
Answer: EDUCATED GUESS
Explanation:
They regulate the heart rhythm.
Heart valves prevent blood from flowing backwards, ensuring unidirectional flow that is essential for effective blood circulation throughout the body.
Explanation:The function of the heart valves is crucial for the cardiovascular system, as they prevent blood from flowing backwards by ensuring unidirectional flow through the heart. There are four valves in the heart: the tricuspid valve, the pulmonary valve, the mitral valve, and the aortic valve.
These valves open to allow blood to move forward and close to prevent it from leaking back into the chamber it came from. This action is vital as it maintains the efficiency and pressure necessary for blood to reach all parts of the body. The unidirectional flow is necessary for efficient circulation, ensuring that oxygen-rich blood reaches the systemic circulation and deoxygenated blood reaches the lungs for oxygenation.
What is the main cause of an earthquake?
O force of gravity
O the shaking of the ground
stress caused by plate movement
waves that ripple from the epicenter
Answer:
stress caused by plate movement
Stress caused by plate movement is the main cause of an earthquake. So, the correct option is C.
What is an earthquake?A abrupt discharge of energy in the Earth's earth's crust that results in seismic waves causes an earthquake, which is the shaking of the planet's surface.
Sudden movement along Earth's fault lines causes earthquakes. The motion releases "elastic strain" energy that has been accumulated in the form of seismic waves, which travel through the Earth and cause the earth to tremble.
The primary cause of an earthquake is stress brought on by plate movement. Buildings, dams, etc. can sustain significant damage as a result of earthquakes. They might also bring about tsunamis, land slides, floods, and fatalities. A disturbance deep within the earth's crust is the reason behind it.
Therefore, the correct option is C.

The behaviorist B.F skinner was a __ when it came to explaining how children learn language
Answer: nurturist
Explanation:
The American psychologist and behaviorist Burroughs Frederick Skinner ( 1904 – 1990) was a Harvard Professor of Psychology. He is considered the pioneer of modern behaviorism. He explained in his book “Behavior of Organisms “ how environmental variables control behavior. He believed that parents’ nurturing shape the child’s language behavior.
Final answer:
B.F. Skinner, a behaviorist, believed children learn language through reinforcement and feedback, but his view was challenged by Noam Chomsky who proposed an innate capacity for language. Today, language acquisition is understood as an interplay of nature and nurture, combining Skinner's behavioral perspective with innate elements suggested by Chomsky.
Explanation:
The behaviorist B.F. Skinner was a proponent of the idea that children learn language through the process of reinforcement and feedback. This perspective posits that behavioral responses, including language, are shaped by environmental stimuli and consequences, such as rewards or punishments. For example, when a child uses a word like cookie, they are met with reinforcement if they receive a cookie or punishment if they are denied. Skinner saw no fundamental difference between verbal behavior, like asking for a cookie, and non-verbal actions, like reaching for one. Skinner's analysis of language suggests that all complex verbal behavior develops from simple beginnings and is then shaped into its more abstract forms, in the same way as any other behavior.
However, Skinner's view on language acquisition was challenged by the linguist Noam Chomsky, who introduced the idea of an innate language acquisition device (LAD) that humans are born with, suggesting that there is an inherent capacity for language learning. Current researchers generally believe that language learning is a combination of innate abilities and environmental influences, a view that combines elements from both Skinner and Chomsky's theories. Consequently, while Skinner's approaches were influential, they are now seen as part of a larger framework that includes biological and cognitive factors.
The rock particles that make up soil come from parent bedrock. Weathering breaks bedrock into smaller and smaller pieces. The characteristics of any soil depend mostly on the type of parent bedrock. Just like you have characteristics that are like your parents, soils have characteristics that are like those of the parent bedrock. Take a look at the soil textural triangle. Soil particles are classified by size; sand particles are the largest and clay particles are the smallest. Most soils are some mixture of these three particles.
Imagine that a soil is 85% composed of weathered sandstone. Over time, a river flowing over the bedrock deposits sand and a very small amount of clay. By using the soil textural triangle, scientists have decided that the soil is mostly likely
A) silt loam.
B) clay loam.
C) loamy sand.
D) sandy silt loam.
The soil in question is option C - loamy sand.
Loamy sand is a soil composition dominated by sand particles, with a small amount of clay particles. According to the soil textural triangle, loamy sand is a soil composition mostly consisting of sand particles (the largest particles) and a smaller amount of clay particles (the smallest particles). The 85% composition of weathered sandstone indicates a high concentration of sand, making loamy sand the most appropriate classification.
The soil textural triangle classifies soils based on their composition of sand, silt, and clay. Each corner of the triangle represents 100% composition of one of these particles: sand, silt, or clay.
Given that the soil is 85% composed of weathered sandstone,
It means that the dominant particle size in the soil is sand. Locate the point on the triangle where the sand percentage is approximately 85%. This point falls within the loamy sand region.The soil's composition aligns with the characteristics of loamy sand, which is a mixture of sand and a small amount of silt or clay. Therefore, the soil is mostly likely loamy sand.

Mendel's genetics has the laws that help to determine the characters of various chromosomes expression and the expression mechanisms. The same genes present on the allele is called as homozygous and the different ones are called as heterozygous.
What is the dominant allele ?
It is the set of genetic expressions which express themselves in the genotype or phenotype of the individual.
Homozygous describes two of the same alleles that express a trait. That means the same of alleles that are controlling a single and same expression. The another one in which a different set of chromosomes are present are called as heterozygous.
Recessive allele is hidden by the presence of another allele that is represented by a lowercase letter where the capital letter is called as a dominant trait expressing gene.
An organisms set of genes that are represented by letters is called as genotype. It is controlling the genetic expression of an individual.
An allele is -expressed while it hides another. It is the expression where one of the allele is getting expressed and the another one is not terming them as dominant and recessive.
This allele tends to hide the presence of another allele, is expressed most often and is represented by a capital letter. It is the dominant gene.

Flagellates are microbes that have a rod-shaped flagellum that helps with their locomotion. Certain flagellates reside inside termites. These flagellates provide enzymes for the termites to digest cellulose, which helps them survive. In turn, the termites provide nourishment to these flagellates. Termites need cellulose for their survival, and flagellates obtain nutrition only from termites. Which statement can be true about the association between these microbes and termites?
A.
The flagellates share a facultative mutualistic association with the termites.
B.
The flagellates and termites share an obligate mutualistic association.
C.
The flagellates share an obligate parasitic association with the termites.
D.
The flagellates and termites share a commensal association.
E.
The flagellates and termites share a facultative parasitic association.
Answer:
B.
The flagellates and termites share an obligate mutualistic association
Explanation:
Organisms of same or different species tend to interact with one another in an ecosystem. The close interaction between two organisms is referred to as SYMBIOSIS. A type of symbiotic relationship is MUTUALISM, which is when both organisms benefits from the relationship.
However, mutualistic relationship can be of different types depending on how dependent the involved organisms are on each other. The example in this question illustrates OBLIGATE MUTUALISM, which is when the organisms involved in the mutualistic relationship depend on one another for survival. This is the case of the termites and the flaggelates where the termite depends on the flaggelate for enzymes that helps them digest cellulose while the flaggelates depend on termite for nourishment/food.
The termite will not survive if it doesn't get enzymes to digest its cellulose while the flaggelates will also not survive if they do not get nourished. Hence, the two organisms share an OBLIGATE MUTUALISTIC RELATIONSHIP.
Termites and flagellates have an obligate mutualistic relationship where the flagellates digest cellulose for the termites, and termites provide habitat and food for the flagellates.
Explanation:The association between termites and flagellates is described as an obligate mutualistic relationship. In this symbiosis, both parties are entirely dependent on each other to survive. The flagellates aid in the digestion of cellulose which is the primary food source of the termite. These protozoans possess bacteria that produce an enzyme called cellulase which is necessary for the breakdown of cellulose into sugars the termite can absorb. Conversely, the flagellates depend on the termites to provide them with a safe habitat and consistent food supply derived from the cellulose-rich wood that termites consume.
Which of the following steps of the water cycle is the only step that has to have living organisms in
order to happen?
A. Transpiration
B. Condensation C. Evaporation D. Preci
Answer:
A. Transpiration
Explanation:
Transpiration is the process of water evaporating from the leaves of plants through holes on the underside of the leaf.
Final answer:
In the water cycle, transpiration (Option A) is the only step that requires living organisms, as it involves water movement through plants and out to the atmosphere.
Explanation:
The step of the water cycle that requires living organisms to occur is transpiration.
This process involves plants absorbing water through their roots, which then moves up through the plant and eventually evaporates from the leaves into the atmosphere. Unlike condensation, evaporation, and precipitation, transpiration specifically involves the biological process of plants.
While condensation is the process of water vapor cooling to form liquid water droplets and precipitation is the water droplets falling from the atmosphere as rain, snow, sleet, or hail, these do not require living organisms to happen. Therefore, the correct answer to the question is A. Transpiration.
