Answer:

D. The system provided an organized way to classify living things and it has been able to grow and develop. There is a place to enter new organisms as they are discovered or new evidence occurs

Explanation:

Carolus Linnaeus is a Swedish Botanist is universally referred to as the FATHER OF TAXONOMY because of his contribution to the development of a system of naming and classifying species, which is still globally recognized today. Linnaeus proposed the binomial nomenclature system which uses two of the hierarchical classification to name organisms i.e. genus and species. For example, humans are Homo sapiens; Homo (generic name), Sapien (specific name).

Modern scientists later modified Linnaeus classification by adding new ranks in order to accommodate new species and removing incorrectly classified organisms but Linnaeus classification remains the foundation. One important modification was the inclusion of a new taxon called DOMAIN.

Fox (Australia); became an apex predator in the lack of competition, and damages the populations of native small placental mammals. 
Hair (Australia); reproduces much quicker than the native species of mammals, increased significantly in numbers, and out competes the native species for the food sources.
African bee (the Americas); much more aggressive and stronger than the native bees and systematically kills their populations.

If a plant is living in a cold environment, which physiological change would help the most with the cool temperatures?
Novosadov [1.4K]

The plant species that live in the colder environment have some adaptations that makes them survive in that conditions

These plants have a well developed vascular system due to which they have the ability to trap every inch of sunlight available for the process of photosynthesis.

Some of the plants shed their leaves and stay in dormant conditions.

Evergreen trees have thick waxy coating that prevents the loss of water.

The plants that grow in arctic regions are small and they grow close to the ground in a specific shape that helps them to shed snow from them.
