Complete the following map organizing one of biology’s major themes.
To complete: The given map showing a major biological theme.
Introduction: The five major themes present in all biological systems are as follows:
Theme 1: “Evolution is the core theme of biology”.
Theme 2: “Life depends on the flow of information”.
Theme 3:“Structure and functions are related”.
Theme 4: “Life depends on the transfer and transformation of energy and matter”.
Theme 5: “Life depends on interactions within and between systems”.
Answer to Problem 1CC
Fig. 1 shows the completed map of evolution, one of the core themes in biology given in the textbook.
Pictorial representation: Fig. 1 shows the completed map of the core theme of biology: evolution.
Fig.1 Evolution as a core theme of biology
Explanation of Solution
(a)
Correct answer: Life
The term “biology” is defined as the branch of science that studies life (in Greek: bio= life; -ologia= study of). Hence, the correct answer is life.
(b)
Correct answer: Evolution
Evolution is defined as the continuous process of changes that have occurred over a long time to transform the living beings from their earliest simplest forms to the present-day wide variety of species. It can be summarized as “descent with modification”, that is, all species have evolved from common ancestors through several continuous changes over time. Thus, evolution is the process that has changed life. Hence, the correct answer is evolution.
(c)
Correct answer: Natural selection
Researcher Charles Darwin proposed the phenomenon of “natural selection” as the mechanism for evolution. In a large population of species, individuals show several variations in their traits; out of which, some variations are more favorable for survival, utilization of resources, and better reproductive success of selected individuals. This phenomenon of better adaptation, survival, and reproductive success of selected individuals due to the presence of certain traits or variations is called natural selection. These selected individuals are able to pass their traits to their next generation, and thus their population increases, slowly by transforming the population, leading to evolution. Thus, natural selection is the mechanism that drives evolution. Hence, the correct answer is natural selection.
(d)
Correct answer: Unity of life
Deoxyribonucleic acid (DNA) is present in most of the living organisms that help in the flow of information from one generation to the other and changes in which lead to evolution. Thus, it is a proof for unity among all life forms.
Evolution has led to the development of various species from a common ancestor through continuous changes. Thus, it shows unity among all life forms. Genetic code as DNA and evolution show unity of life. Hence, the correct answer is unity of life.
(e)
Correct answer: Domains of life
DNA that encodes the genetic information is present in most of the living organisms classified into various domains of life. There are a large number of organisms of various types from simple single-celled bacteria to highly complex and multicellular animals. The basis of their diversity is the genetic information coded in their genetic material, usually DNA. Differences in DNA sequences cause diversity among organisms belonging to different domains of life. Hence, the correct answer is domains of life.

However, a SNP in the position shown in gray (right) would prevent cleavage at this site by EcoRI One of the SNPs in B. rapa is found within the Park14 locus and can be detected by RFLP analysis. The CT polymorphism is found in the intron of the Bra013780 gene found on Chromosome 1. The Park14 allele with the "C" in the SNP has two EcoRI sites and thus is cleaved twice by EcoRI If there is a "T" in that SNP, one of the EcoRI sites is altered, so the Park14 allele with the T in the SNP has only one EcoRI site (Fig. 5-3).

- From your previous experiment, you found that this enhancer activates stripe 2 of eve expression. When you sequence this enhancer you find several binding sites for the gap gene, Giant. To test how Giant interacts with eve, you decide to remove all of the Giant binding sites from the eve enhancer. What results do you expect to see with respect to eve expression?arrow_forwardWhat experiment could you do to see if the maternal gene, bicoid, is sufficient to form anterior fates?arrow_forwardYou’re curious about the effect that gap genes have on the pair-rule gene, evenskipped (eve), so you isolate and sequence each of the eve enhancers. You’re particularly interested in one of the enhancers, which is just upstream of the eve gene. Describe an experimental technique you would use to find out where this particular eve enhancer is active.arrow_forward
