Answers

Scientists group organisms into kingdoms by looking at specific characteristics. The characteristic of the carrot plant is eukaryotic. Organisms with eukaryotic cells are whose cells contain a nucleus and other organelles enclosed within membranes.

Explanation:

Eukaryotes are organisms whose cells have a nucleus surrounded by membranes, unlike prokaryotes. Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and regulates the structure of proteins and ribosomes.

The carrot plant is characterized to be a eukaryotic organism belonging to the Kingdom Plantae.

What are eukaryotic organisms?

Eukaryotic organisms are organisms that have cell nuclei and membrane-bound organelles, which are classified into four different kingdoms (Protista, Animalia, Plantae and Fungi).

Eukaryotic organisms are composed of one (unicellular) or more cells (multicellular organisms).

Plants are eukaryotic multicellular organisms belonging to the kingdom Plantae.

In conclusion, the carrot plant is characterized to be a eukaryotic organism belonging to the Kingdom Plantae.

Which formation is the result of wind erosion?

Answers

Of the following given choices;

A. glacial erratics B. U-shaped valleys C. unusually shaped rocks D. mudslides.

The answer is; C.

The wind carries soil particles is it blows. These soil particle hit on rocks in their path and over time gradually erode the rocks. An example of this type of erosion is the aeolian process. Usually the bottom o the rock is eroded more than the top. This is because the bottom is hit by larger soil particles that are heavier to carry by the wind. An example of rock formed in this process is attached in the picture below.

which term describes a mechanism by which the internal conditions of an organism are kept at set values without regard to the external conditions?

Answers

The answer is homeostasis.

Homeostasis is a mechanism which controls internal conditions of an organism so that internal conditions remain stable without regard to the external conditions. So, it regulates body temperature, water level, sugar level, etc. It works through negative feedback mechanism. For example, if body temperature is increased, the body detect the change and activate mechanisms that decrease body temperature. Without homeostasis, the organisms could not survive.

How does taxonomy help us understand relationships among organisms on earth? What kinds of evidence do scientists use in taxonomy?

Answers

Taxonomy helps us understand relationships among organisms on earth because you can produce a genetic tree diagram which starts from present day animals and goes back to the first early life forms. Scientists will use living organisms and extinct organisms either from fossils, from drawings or from photographs
