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.

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.

The characteristics that are physically called as phenotype that control the physical features along with the physical expressions of an individual.

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.

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.

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.

Answer:

stress caused by plate movement

Stress caused by plate movement is the main cause of an earthquake. So, the correct option is C.

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 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,

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.

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.

In the nitrogen cycle, Nitrifying bacteria is responsible for converting ammonia into nitrates that can be used by plants. So, the correct option is (C).

The nitrogen cycle is defined as the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates in atmospheric, terrestrial and marine ecosystems where nitrogen is fixed through both biological and physical processes.

The processes which participate in the cycling of nitrogen through the biosphere:

(1) Nitrogen fixation,

(2) Decay

(3) Nitrification

(4) Denitrification.

The nitrifying bacteria convert ammonia to nitrites or nitrates where the Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants.

Thus, in the nitrogen cycle, Nitrifying bacteria is responsible for converting ammonia into nitrates that can be used by plants. So, the correct option is (C).

Explanation:

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.

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.

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.

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.
