Predators have certain advantages over the prey as the prey are vulnerable and get hunted and also the predators perform the function of regulating prey population.

Prey are those animals which get hunted by the predators and predators are the animals which kill or prey on other animals and obtain their nutrition from them.

Predators form a very crucial part of any particular ecosystem and have many advantages over a prey as the animal which is the prey is vulnerable and is hunted down by the predator. Due to this predator-prey relationship, predators keep the population of the prey species in check and they also help eliminate the sick as well as old animals which are a part of the prey species. They also help ensure the transfer of energy from one trophic level to the next trophic level and also by feeding on these animals they also reduce the amount of waste in the environment.

Natural selection is said to have occurred when individuals having the most favorable traits survive and reproduce.

Natural selection is a very key mechanism of evolution in which only the organisms or the individuals of a population which have desirable traits or characteristics are naturally selected and survive whereas the ones which do not have any desirable characteristics do not survive. This concept was given by the naturalist Charles Darwin.

The genes which bring about variations in an organism's genotype and give the organism a survival advantage over others are preserved and protected and are passed on to the next generation.

Natural selection is a process by which organisms that are better adapted to their environment tend to evolve new traits.

In general ,Natural selection is considered as the process through which organisms develop variation in traits, which make them more fit to survive in changing environment survival. Thus , Natural selection primely depends on the environments. Natural selection doesn't depend on the traits that are genetically superior natural trait but they acts on existing heritable variation . These Heritable variation comes from random mutations.

Hence , we can say that Development of genetically modified organisms is  of artificial selection but natural selection come over years of adaptation.

Irrigation that uses a large sprinkler system and is moved manually and experiences very large evaporation losses are called drip Irrigation

Irrigation or watering is an effort made by humans to irrigate agricultural land. In the modern world, there are currently many models of irrigation that can be done by humans.

One of them is drip irrigation. Drip irrigation is a way of giving water to plants directly on the soil surface. This type of irrigation uses a tool called an emitter or dropper and is moved manually. This tool is used to spread water throughout the soil profile, both horizontally and vertically as a result of gravity and capillarity.

The waste product of anaerobic exercise is lactic acid.

During anaerobic exercise, such as weightlifting or sprinting, the body's demand for energy exceeds the oxygen supply to the muscles. The body then turns to anaerobic metabolism, which generates energy through the breakdown of glucose without the use of oxygen. This process produces lactic acid as a byproduct.

Lactic acid is also known as lactate and it causes the burning sensation in muscles during high-intensity exercise, when the accumulation of lactate exceeds the body's ability to remove it. The accumulation of lactic acid can also cause muscle fatigue, which is why anaerobic activities are typically of shorter duration than aerobic activities.

Due to the fact that carbon is expelled as soon as it is absorbed, the resident time would be zero.

The carbon cycle is essential to life on Earth. Because nature tends to keep carbon levels in balance, the amount of carbon that is naturally released from reservoirs equals the amount that is naturally absorbed by reservoirs. By maintaining this carbon balance, the planet can support life indefinitely.

The carbon cycle appears to sustain a balance over time that prevents all of the carbon on Earth from either entering the atmosphere (as is the case on Venus) or from being totally stored in rocks. The Earth's temperature is largely maintained by this equilibrium.

Evolution and Galapagos Tortoises Charles Darwin, a British scientist, examined indigenous flora and animals when visiting the Galapagos Islands in 1835.

He got attracted by species that appeared to be similar to those found on the mainland yet had many morphological differences that were unique to distinct islands.

The core concept of biological evolution is that organism populations and species change through time. When we think of evolution today, we are more likely to associate it with one person: the British biologist Charles Darwin.

Darwin observed that the characteristics of numerous animals, such as tortoise shell forms, changed from island to island in the Galápagos Islands. - He discovered that various, yet related, animal and plant species occupied distinct habitats within a small space.

The data suggest that Turtles are less evolutionary related to humans when compared to chimpanzees and closer compared to tunes since amino acid differences account for the term divergence between species.

The term divergence between species in evolution makes reference to the difference between species in a given homolog protein sequence and or any other feature derived from a common ancestor. In this case, we can see that the aminoacid differences are higher between humans and tunas, thereby these species are evolutionary distant when compared to chimpanzees and also compared to humans and turtles (mammals and reptiles are evolutionary closer compared to tunas).

Therefore, with this data, we can see that the term divergence between species is based on the presence of homologies between individuals due to a common ancestor such as occurring between species.

According to size, the molecules that enter the gel will separate. Because they do not need to squeeze through the gel's pores as much as the larger ones do, the smaller ones will travel further down the gel.

A laboratory procedure called electrophoresis is used to divide DNA, RNA, or protein molecules according to their size and electrical charge. Colloidal particles migrate during electrophoresis under the influence of an applied electric field. In cataphoresis, negatively charged particles move away from the anode while positively charged particles move closer to it (anaphoresis). Colloid particle charges can be determined via electrophoresis.

The phenomenon that most biomolecules exist as electrically charged particles with ionizable functional groups serves as the foundation for electrophoresis. At a specific pH, biomolecules can exist as either positively or negatively charged ions in a solution. The technology of electrophoresis is crucial for the separation and examination of nucleic acids. At the lab bench, cloned DNA fragments are frequently isolated and worked with using nucleic acid electrophoresis.

The phosphorus cycle is a kind of biogeochemical process.

The phosphorus cycle is a kind of biogeochemical process in which phosphorus moves through the environment, including the biosphere, hydrosphere, and geosphere. The process is driven by both natural and human factors, and it is closely connected to other biogeochemical cycles such as the carbon and water cycles.

In the natural process, Phosphorus enters the ecosystem through weathering of rocks and minerals, and it is taken up by plants through the roots. Then, the phosphorus is passed along the food chain from plants to herbivores to carnivores. Once the organisms die, the phosphorus is returned to the soil through decomposition by microorganisms, and the cycle continues. Human activities such as agriculture and mining can also affect the phosphorus cycle by releasing or removing large amounts of phosphorus from the ecosystem.

where is the question

Explanation:

Adding a plant to the flask will  help reduce the amount of carbon dioxide produced and is therefore denoted as option A.

This is referred to as the process in which green plants manufacture food in the presence of sunlight. Plants trap sunlight through the green pigment known as chlorophyll and the energy from the sun is then used to power the reaction.

Plants use compounds such as carbon dioxide and water to produce glucose and oxygen and the equation of reaction can be seen below:

6CO₂ + 6H₂O → C₆H₁₂O6 + 6O₂

This is therefore the reason why to reduce the amount of carbon dioxide then it is best to add plants to the flask so that they are used up for their photosynthetic activities hence option A is the correct choice in this scenario.
