What factors should we consider when determining why the chicken "loses" to the fox? A chicken can fly and perch on higher place

s than the fox can likely get to. Does one animal have worse hearing than the other? Or are its other senses not as keen? Does one animal sleep more soundly or just more than the other? What necessary information would you need to determine why one of these animals (the fox) tends to always come out on top when in some other scenarios the obvious result does not turn out as expected? Fully explain your rationale. Identify a different real-world situation and interpret the results of the outcome. Were the results expected? Fully explain your rationale.

Answer:

Domestic chicken evolved by artificial selection and therefore they are less adapted to survive in nature where prey populations coexist with the predators (like the fox).

Explanation:

Commercial chicken (<em>Gallus gallus domesticus</em>) is the result of the artificial selection exerted by early farmers in China 8,000 years ago. Artificial selection is aimed at benefiting one or more particular traits in detriment of others. Domestic chickens were selected by humans to produce fast-growing meat animals in detriment of traits found in wild progenitors of modern chicken. In consequence, the processes of artificial selection result in a loss in genetic diversity in traits that are not being selected including, for example, phenotypic characteristics associated with the ability to avoid predators.

navik [9.2K]

A researcher is studying how depression tends to be experienced by people of different ages. The researcher interviews depressed adolescents, young adults, individuals in their 30s and 50s, and those over 70 years old. The research design being used is called <u>cross-sectional</u>.

<u>Option: D</u>

<u>Explanation:</u>

A kind of design for observational study is understood as a cross-sectional framework. In a cross-sectional analysis the investigator simultaneously tests the participants in the study's result and exposures. Through cross sectional studies one can estimate the prevalence of disease.

A cross-sectional analysis, for instance, could be used to assess whether vulnerability to specific risk factors would correlate with specific outcomes. For illustration, a researcher may gather cross-sectional data about past smoking habits and current lung cancer diagnoses.

You perform an experiment in which you take 16 pots of strawberry plants and give half of them 1 gm of ammonium nitrate per lite
svetlana [45]

Answer:

homeostasis.

Explanation:

Homeostasis is the process whereby living systems maintain a stable internal environment despite changes in environmental conditions. Plants, like every other living organisms also perform this process to keep their internal environment in a stable state.

According to the question, some plants were exposed to ammonium nitrate, which serves as a nutrient, and 16 hours of sunlight needed for photosynthesis to take place. The plants exposed to ammonium nitrate and 16 hours sunlight grew taller because they had access to nutrients needed to bring about the process of photosynthesis, which provides the plant with energy source (Glucose).

The uptake of nutrients like ammonium nitrate by the plants is done in order to maintain a homeostatic internal environment. Without nutrients, which is the purpose of the ammonium nitrate, plants cannot grow. Hence, the plants exposed to ammonium nitrate, take it in to keep their internal environment functioning.
