Question

statements about some plants

statement i: chickpeas originated in türkiye, and they were small and angular in shape. they were introduced to india, where farmers grew specific chickpea seeds that, over time, resulted in todays larger and rounder chickpea.

statement ii: fig trees are native to asia but were brought to mexico in the 16th century by europeans. today, fig trees are found across north america.

statement iii: scientists have identified genes in the dna of the tree species dracaena cambodiana. these genes play a role in the trees ability to produce a liquid called dragons blood that is known to have medicinal properties.

statement iv: apples turn brown once they are cut due to a gene that causes the production of a particular protein. scientists isolated and modified the gene of the granny smith apple to prevent the protein from being produced, resulting in the production of granny smith apples that do not turn brown.

question 3
which of the following rows identifies the statement that describes an example of artificial selection and identifies the statement that describes a variation within a species caused by humans?

\

$$\begin{tabular}{|c|l|l|} \\hline row & artificial selection & variation within species caused by humans \\\\ \\hline \\bigcirc & i & iii \\\\ \\hline \\bigcirc & i & iv \\\\ \\hline \\bigcirc & ii & iii \\\\ \\hline \\bigcirc & ii & iv \\\\ \\hline \\end{tabular}$$

<reasoning>

Analyze Statement I

Statement I describes how farmers grew specific chickpea seeds over time, which resulted in today's larger and rounder chickpeas. This process of humans selecting desirable traits to breed over generations is the definition of artificial selection (selective breeding). Therefore, Statement I represents "Artificial Selection".

Analyze Statement II

Statement II describes the introduction of fig trees from Asia to Mexico and North America. This is an example of species introduction or geographic distribution changes, not artificial selection or genetic variation caused by humans.

Analyze Statement III

Statement III describes scientists identifying natural genes in the DNA of Dracaena cambodiana that produce a medicinal liquid. This is an identification of naturally occurring traits, not a human-caused variation.

Analyze Statement IV

Statement IV describes scientists isolating and modifying a gene in Granny Smith apples to prevent them from turning brown. This genetic modification directly alters the genetic makeup of the organism, creating a new variation within the species that is directly caused by human intervention. Therefore, Statement IV represents "Variation Within Species Caused by Humans".

Match with Options

We need a row where:

• Artificial Selection is identified as Statement I.
• Variation Within Species Caused by Humans is identified as Statement IV.

Looking at the table:

• Row 1: I and III
• Row 2: I and IV
• Row 3: II and III
• Row 4: II and IV

The correct row is the second row (I and IV).
