Concept explainers

The history and science of origin and evolution comprise two events, the beginning of life and expansion of life. Our earth originated about 4.5 billion years ago. The term evolution is derived from two Latin words and means the act of unfolding or unrol…

Cladistics

Cladistics is a technique in the classification of organisms, where they are grouped into different clades. The proof for the relationships that are hypothesized is based on the shared derived characteristics known as synapomorphies. These characteristic…

Outgroups

Outgroups are significant in studying cladistics or phylogenetics (that describe the evolutionary relationship between different organisms). Further, it is also important to understand the differences and similarities between different organisms.

Taxonomy

It is the branch of biology that works with the identification of organisms at first, then naming, and classification of them into phenetic or phylogenetic groups (a classification system). In other words, it is the scientific study of biological diversi…

Phylogenetics

Phylogenetics is the scientific study of how various groups of organisms are related at the evolutionary level. It finds the relationship between various organisms based on their evolutionary similarities and differences. It is a part of the taxonomy. Al…

1:42 PM ១ 99% Apart from food, plants need other nutrients like water and minerals. Nitrogen, a mineral, is an important part of all living cells. All organisms need nitrogen in order to grow and repair. Although nitrogen exists in its elemental form in the atmosphere, it cannot be directly used by plants. 7 Where else can plants obtain their nitrogen from? Plants make their own nitrogen. B Plants get it from animals. Plants get it from the soil. D Plants have special structures to break down atmospheric nitrogen. v3.7.63.140.4 | 6763e9417a3dbb80fa0f87b2 | Dec 19, 2024 | 3:07 PM | 84126 | en_8
