Answer 2

Answer:

Convection occurs due to the different relative densities of materials.

Explanation:

Heating within the Earth lowers the density of parts of the Earth's mantle. In areas where these lower-density materials lie beneath cooler, higher-density materials, an unstable condition develops. To stabilize this condition, the cooler, higher-density materials flow downward while the hotter, lower-density materials flow upward. This vertical flow of material is called convection.

Organisms need energy in the form of nutrient in order to reproduce.

What is reproduction?

Reproduction is defined as a biological procedure whereby an organism creates children that are biologically identical to the mother. Generation after generation, reproduction makes possible and ensures the survival of species. It is the primary aspect of earthly life. The continuation of the species and prevention of its extinction are guaranteed by reproduction. It contributes to evolution by generating variants through genetic recombination.

All living things require energy to sustain their structures, develop and reproduce, and adapt to their surroundings. Organisms are able to transform the chemical energy found in molecules into energy that may be used for cellular processes through a series of chemical events known as metabolism.

Thus, organisms need energy in the form of nutrient in order to reproduce.

Suppose you were making a dichotomous key to identify the three types of leaves shown below. Which of the following traits could you use to classify these leaves into separate groups?

Question 3 options:

Presence or absence of veins (the lines) in the leaves.

Presence or absence of stems.

How leaves are arranged on branches.

Answers

You can classify these leaves into groups of: color, lineament, and shape.

The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.

What is a dichotomous key?

A dichotomous key is a methodology employed by taxonomists to identify organisms from different taxonomic groups. The dichotomous keys are always funded on phenotypic traits. Dichotomous keys can be considered as two different options to identify a given feature of an organism.

Monocots are the plants having only one cotyledon or seed with only one leaf also called monocotyledons. Dicots are the plants having two cotyledons or seed with two leaves.

Monocots and dicots have few characters that make them easily recognizable such as venation pattern: The arrangement of veins in a leaf is called the venation pattern; dicots have a reticulate or network of veins type venation, while monocots have parallel venation.

Therefore, The specification 'leaves found in deciduous forest and leaves found in tropical forest' should not be used when making this dichotomous key. It is not part of a classification system.
