a group of similar organisms that can breed together to produce fertile offspring

A division of living things in the classification system. The five kingdoms are animals, plants, fungi, protist and prokaryotes.

The three domain system of classification organises organisms into  three large groups: Bacteria, Archaea and Eukaryota.

the physical characteristics of an organism

Biology

Pupils learned that random genetic mutation is a source of heritable variation, and that evolution occurs through the natural selection of genetic variants linked to advantageous phenotypes.

Classification in modern biology

Which scientist is known as the father of modern classification and introduced the binomial naming system?

Starting with the largest group, sort the groups of Linnean classification into the correct order. 

What is the binomial name for the Santiago tortoise?

He introduced the binomial naming system.

He used DNA sequences to refine classification.

He classified organisms based on physical characteristics.

What is the significance of Woese's contribution to classification?

According to the three-domain system, which domain includes animals, plants, fungi, and protists?

Which domain contains organisms that are often extremophiles and live in extreme environments?

Which type of microsope is shown in the image?

 neither prokaryotic nor eukaryotic cells

Which type of cells contain membrane bound sub-cellular structures, including a nucleus?

Which type of cell, prokaryotic or eukaryotic, is generally smaller in size?

If a bacterial cell has a diameter of 1.5 micrometres, how many times smaller is it compared to a eukaryotic cell with a diameter of 15 micrometres?

Light microscopes have a higher resolution than electron microscopes.

Llight microscopes have a lower resolution than electron microscopes.

Light microscopes have a higher magnification than electron microscopes.

Light microscopes have a lower magnification than electron microscopes.

Which of the following statements about microscopes are true?

Calculate the real size of a cell if its image size is 200 micrometres and the magnification is 400x.
