Answers

Correct answer: B). Easy to cultivate and fertile

The prairie is grassland soils that possess a dark colored surface and these soil are highly fertile in nature. These soils are rich in minerals like calcium and magnesium.

The dark color of soil comes from the added organic matter to the soil that comes from the roots of prairie plants. They are formed in the areas that are too dry to be forested, but too wet to be desert.

Hence, the correct answer would be option B.

Scientists group organisms into kingdoms by looking at specific characteristics. Which is a characteristic of a carrot plant? no cell walls heterotrophic unicellular eukaryotic

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.

The principal characteristic that differentiates temperate and tropical rainforests is __________

Answers

Answer;

Latitude

The principal characteristic that differentiates temperate and tropical rain-forests is latitude.

Explanation;

  • There are two types of rain-forests, namely, the tropical rain-forests and the temperate rain-forests. These two types share some similarities such as being rich in plant and animals species with a greater diversity in tropical rain forest.
  • However they differ in a number of ways; tropical rain-forests are warm and moist; while temperate rain-forests are cool.
  • Tropical rain-forest, forested areas must: Lie between the Tropic of Cancer and the Tropic of Capricorn, receive rainfall regularly throughout the year, remain frost and free through out the year with little fluctuations.

Write the formula that shows the release of energy by the mitochondria.

Answers

Answer;

C6H12O6 + 6O2  6CO2 + 6H2O + ATP

Explanation;

- Mitochondria are tiny organelles inside cells that are involved in releasing energy from food, a process called cellular respiration.

-During cellular respiration nutrients such as glucose are broken down in the presence of oxygen to release energy in form of ATP and water together with carbon dioxide as by products. The energy released may be utilized by the cells to drive cellular processes, such as growth and movement.

Which statement describes how water is pulled up through the xylem to the leaves of the plant? As water exits the leaf, hydrogen bonding between water molecules pulls more water up from below. A As water exits the leaf, signals are sent to the roots to pump more water up to the leaves through the xylem by adhesion. B Evaporation from the leaf decreases the hydrogen bonds that form between the water molecules in the xylem, which helps the water molecules to be pulled up the xylem. C Evaporation of water from the leaf increases the hydrogen bonds that form between water molecules in the air, providing the energy for transport.
