Explanation:

Artificial selection selects the traits that are already present in the animal or human. On the other hand genetic engineering creates new/different traits.

In artificial selection scientist only breed the desirable traits. With genetic engineering use DNA to specifically manipulate the genome. Example: A way to change the genome is to enter genes from another organism.

Abiotic factors can cause harmful effects such as acid rain when too much is releadein to the atmosphere are Carbon, and Sulfur.

Acid deposition, often known as acid rain, is a general name for any type of precipitation that contains acidic elements, such as sulfuric or nitric acid, which falls to the ground from the atmosphere in wet or dry forms. This can apply to rain, snow, fog, hail, and even corrosive dust. Sulfur dioxide (SO2) and nitrogen oxides (NOX) that are released into the atmosphere and carried by air currents and wind result in acid rain. Water, oxygen, and other molecules react with the SO2 and NOX to generate sulfuric and nitric acids. While some of the SO2 and NOX that create acid rain come from natural sources like volcanoes, the majority of it is produced by burning fossil fuels.

Calico is a coat color found in cats that is caused by sex-linked co-dominant alleles.

The calico cat displays a mixed color of red and black, depending on which of her two X chromosomes is inactivated. The allele that codes for orange hair color is dominant, while the black color allele is recessive. In cats, the X chromosome carries the gene that determines coat color, and calico cats have two different versions (or alleles) of this gene. One allele produces orange fur, the other produces black fur.

Codominance actually means that neither allele can block or camouflage the expression of the other allele. Co-dominance can also occur in less obvious traits such as blood type.

Impurities increase a sample's boiling point and increase the range of temperature at which the sample will boil.

The presence of impurities in a substance can affect its boiling point. Generally, a pure substance has a sharp and well-defined boiling point, meaning that it will boil at a specific temperature under a given set of conditions.

However, the presence of impurities can raise or lower the boiling point of a substance and make it more difficult to accurately determine its boiling point.

The water flea will compete with native species for food, leading to a decrease in organisms that are important to other species. The Correct option is B

The introduction of spiny water fleas to the lake poses a significant ecological concern. Since they consume zooplankton, which is also a vital food source for native fishes, competition for this shared resource is inevitable. The water fleas will compete with native species for the available zooplankton, resulting in a decrease in the abundance of these organisms.

This can disrupt the food web dynamics and have adverse effects on the population of native fishes and other species that rely on zooplankton as a crucial part of their diet. The spiny water flea's spread through human activities enhances their invasion of new lakes, exacerbating the competition and potential negative impacts. The Correct option is B

The correct option is C) analyzing large numbers of offspring. Mendel developed the basic principles of heredity by performing experiments with pea plants and carefully analyzing the inheritance patterns of traits in their offspring.

He performed controlled crosses between pea plants that differed in one or more traits, such as seed color or flower color. By analyzing the resulting offspring in large numbers and counting the proportion of offspring that inherited each trait, he was able to deduce fundamental principles of inheritance such as dominance, segregation, and independent assortment. Mendel's work laid the foundation for modern genetics and provided a framework for understanding the transmission of traits from one generation to the next.

The correct answer is A drought that kills most of the grass. An environment may be described as an organic network or area that incorporates all residing organisms (biotic factors) and the bodily environment (abiotic factors) with which they interact.

Basically, an environment offers the subsequent important offerings which are very critical for the sustenance of lifestyles for all residing organisms;

This in the long run implies that manufacturers are normally the muse of a food chain and are constantly determined on the top (first layer) of the food chain. In this wasteland meals chain, the grass is the manufacturer and is key for the survival of the alternative residing organisms i.e the grasshopper, mouse, and owl.

In an environment, manufacturers confer with the residing organisms able to produce their personal meals and might offer power or meals for different residing organisms (consumers) in a meals chain.

Hence, a drought that kills maximum of the grass is an alternate withinside the environment that might have the best terrible impact on the alternative residing organisms (grasshopper, mouse, and owl).

This situation would illustrate allopatric speciation. The correct option is A) allopatric speciation.

The situation described, where two populations of house finches that were previously geographically separated come into contact but are unable to interbreed, is characteristic of allopatric speciation. Allopatric speciation occurs when a single population is divided into two or more geographically isolated populations. Over time, these isolated populations may experience different selective pressures and accumulate genetic differences, leading to the development of distinct species.

In the case of the house finches, the population in western North America and the introduced population in New York City were initially separated by a significant geographical distance. However, as the New York City population expanded and their range overlapped with the western population, they were no longer able to interbreed, suggesting the development of reproductive isolation and the potential formation of a new species. Therefore, this scenario is best explained by allopatric speciation.
