What is the unity and diversity of life?

INTRODUCTION. Evolution explains the unity and diversity of life. Unity is explained as all living things share the same fundamental characteristics because they are descended from a common ancestor. Diversity is explained as all populations adapt to their varying habitats.

What process explains the unity and diversity of living organisms on our planet?

Evolution is the unifying theory of biology. It explains the unity and diversity of life.

How does the process of evolution drives the diversity and unity of life?

Biological evolution explains both the unity and the diversity of species and pro- vides a unifying principle for the history and diversity of life on Earth. … Natural selection can act more rapidly after sudden changes in conditions which can lead to the extinction of species.

How does the theory of evolution explain the diversity of life?

Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments and the diversity of environments that exists promotes a diversity of organisms adapted to them.

What is an example of unity in diversity?

Religion caste food habits languages and sociol customs etc are the examples of unity in diversity. Explanation: India is a brilliant example of unity in diversity. In India people of diverse religions cultures castes sects etc.

Why is the cell considered the unity and diversity of the living?

All livings organisms are with unicellular origin. The cells have a common structure like cell membrane DNA RNA and necessary enzymes. The genetic code of protein synthesis is almost similar with few exceptions. This shows unity in design.

How does the concept of descent with modification explain both the unity and the diversity of life?

How does the concept of descent with modification explain both the unity and diversity of life? The idea of descent is that similar organisms came from one prehistoric/ancient organism. This created diversity as organisms developed modifications to the original ancestor.

How does the concept of unity and diversity connect to and explain the concept of the Tree of life?

The tree of life concept deals with descent with modification. Shared anatomy reflects inheritance from a common ancestor which shows unity. The diversity is shown through how the traits have changed and adapted to have new functions and altered structures in different species.

What is the characteristics of diversity and unity?

It is a concept of “unity without uniformity and diversity without fragmentation” that shifts focus from unity based on a mere tolerance of physical cultural linguistic social religious political ideological and/or psychological differences towards a more complex unity based on an understanding that difference …

What molecule carries all of the genetic instructions for how do you build proteins?

Deoxyribonucleic Acid (DNA) DNA is the chemical name for the molecule that carries genetic instructions in all living things. The DNA molecule consists of two strands that wind around one another to form a shape known as a double helix.

What is evolutionary diversity?

Phylogenetic diversity is the sum of the total evolutionary history or amount of the tree of life present in a given community and is quantified as the sum of the branch lengths which are measured in units of time from a phylogeny that represents all species in a given community (total lineage diversity)16.

How do vestigial structures provide evidence for evolution?

Structures that have lost their use through evolution are called vestigial structures. They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure or using it for a different purpose.

What is evolutionary unity?

Evolutionary unity means structures that are common in all forms of life (both prokaryotes and Eukaryotes). Plasma membrane and DNA are the best cellular structures to study evolutionary unity. … DNA is also found in both prokaryotic and Eukaryotic cells.

What molecules were present on early Earth?

Considering the atmosphere of the primitive earth to have contained water vapor carbon dioxide carbon monoxide methane and ammonia and/or nitrogen then in the presence of an energy source such as sunlight or lightning a number of small molecules like hydrogen cyanide HCN are formed.

What processes maintain genetic unity and diversity?

Meiosis and fertilization create genetic variation by making new combinations of gene variants (alleles). In some cases these new combinations may make an organism more or less fit (able to survive and reproduce) thus providing the raw material for natural selection.

Which is the best example of unity in diversity?

India is the best example of unity in diversity.

How can there be unity in diversity?

In order to promote unity in diversity we should consider a number of steps. First there needs to be proportionate development. Second we should respect the will aspirations and needs of the people. Third we should identify genuine problems ascertain their root causes and address them appropriately.

What is unity in diversity class 7?

Answer:Unity in diversity is a concept of “unity without uniformity and diversity without fragmentation“[1] that shifts focus from unity based on a mere tolerance of physical cultural linguistic social religious political ideological and/or psychological differences towards a more complex unity based on an …

What is diversity in living world?

Biology is a branch of science that deals with the living beings and their functions. There is a great diversity of living beings on this planet. The difference between living beings and non-living matter was perceived by early man.

What are some examples of unity of life?

Examples: • universal usage of DNA to store genetic information • the ribosome technique of protein synthesis • proteins serve as enzymes and catalysts • the same 20 amino acids are always used and only left-handed ones • a universal genetic code • DNA triplets coding for same amino acid • the use of proteins and …

What is the diversity of living things?

Biodiversity refers to the variety of life and its processes including the variety of living organisms the genetic differences among them and the communities and ecosystems in which they occur.

What is the best way to determine how closely organisms are closely related?

2. What is the best way to determine if two species are closely related? The best way is to compare the DNA of the two species. The more nitrogenous bases and amino acids two species have in common the more closely related they are.

What is descent with modification?

Darwin defined evolution as “descent with modification ” the idea that species change over time give rise to new species and share a common ancestor. The mechanism that Darwin proposed for evolution is natural selection.

Why do anatomical and molecular features often fit a similar nested pattern?

Explain why anatomical and molecular features often fit a similar nested pattern. … Specific anatomical and molecular features are shared by a narrow range of species are not shared by a more broad range of species. However other features are shared not only among their narrow range of species but also a broader range.

Which of the following describe members of the Kingdom Protista?

The Kingdom Protista consists of eukaryotic protists. Members of this very diverse kingdom are typically unicelluar and less complex in structure than other eukaryotes. In a superficial sense these organisms are often described based on their similarities to the other groups of eukaryotes: animals plants and fungi.

What are the small chemical units that can combine to form molecules?

The small molecular units are called monomers (mono means one or single) and they are linked together into long chains called polymers (poly means many or multiple). Each different type of macromolecule except lipids is built from a different set of monomers that resemble each other in composition and size.

How does each organism living on earth survive and share common characteristics?

All living organisms share several key characteristics or functions: order sensitivity or response to the environment reproduction growth and development regulation homeostasis and energy processing.

What is unity in diversity in sociology?

It connotes a sense of one-ness a sense of we-ness. It stands for the bonds which hold the members of a society together. Unity in diversity essentially means “unity without uniformity” and “diversity without fragmentation”. It is based on the notion that diversity enriches human interaction.

Which part of a DNA molecule carries the genetic instructions?

Which part of a DNA molecule carries the genetic instructions that are unique of each individual: the sugar-phosphate backbone or the nitrogen-containing bases? The backbone is the sane in all Nitrogen bases. The nitrogen containing based provide the genetic unique instructions for each individual.

How does the cell use both DNA and RNA to direct protein synthesis?

A DNA strand is used as a template for a new RNA molecule. In this way pre-mRNA is made which becomes mRNA after the introns are removed. A mRNA molecule enters the ribosomes where transfer RNA attaches to it.

What are the RNA base pairs?

RNA consists of four nitrogenous bases: adenine cytosine uracil and guanine. Uracil is a pyrimidine that is structurally similar to the thymine another pyrimidine that is found in DNA. Like thymine uracil can base-pair with adenine (Figure 2).
