In biology, the population growth is the increase in the number of individuals in a population. The growth of population can be limited by environmental factors, such as food shortages, predators, lack of space, weather, and habitat deterioration. The carrying capacity also affected by these environmental factors. The number of individuals that can live in an environment indefinitely is called carrying capacity.

Question

Chapter 19, Problem 1TQ

Summary Introduction

In biology, the population growth is the increase in the number of individuals in a population. The growth of population can be limited by environmental factors, such as food shortages, predators, lack of space, weather, and habitat deterioration. The carrying capacity also affected by these environmental factors. The number of individuals that can live in an environment indefinitely is called carrying capacity.

Expert Solution & Answer

Answer to Problem 1TQ

A group of interacting individuals of a single species located within a particular area is called as a population. Therefore, option (d) is correct.

Explanation of Solution

Justify the reasons for the correct statement:

The term population in biology refers to all the organisms of the single species or group which live in a particular geographical area and it has the capacity of interbreeding.

Option (d) is given as, “a population”.

Hence, the option (d) is correct.

Justify the reasons for the incorrect statements:

Option (a) is given as, “a biosphere”.

The worldwide sum of all ecosystems is called as biosphere and it is also known as ecosphere. It is the part of sea, land, and atmosphere in which organism is able to live. Thus, it does not contain a single species located within a particular area. Hence, it is a wrong answer.

Option (b) is given as, “an ecosystem”.

An ecosystem is a large community of living organisms which includes animals, plants, and microbes in a particular area. Thus, the ecosystem does not contain an organism of the single species or group. Hence, it is a wrong answer.

Option (c) is given as, “a community”.

An interacting group of two or more species lives in a common location in a particular interval of time is called as a community. Thus, the community also does not contain an organism of single species. Hence, it is a wrong answer.

Hence, options (a), (b), and (c) are incorrect.

Conclusion

Therefore, the number of living things or an organism that live in a particular area is known as a population.

Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out. What type of bias is there in this study? If the company who makes the medication funds this research, what type of bias might exist in this research work?
