You would use the digestive system (which includes your mouth and teeth) to chew, swallow, and begin digesting the carrot. You would use the nervous system to taste and smell the carrot. You would use the muscular system to close and open your jaw to chew the carrot and also to raise the carrot to your mouth and to maintain posture. You would also use the muscular system to swallow and digest the food using peristalsis (which is the back and forth motion by smooth muscle to churn the carrot). You would use the skeletal system (specifically the maxillae (upper jaw and hard palate) and the mandible (lower jaw)) as support for your muscles to chew the carrot and the skeletal system to maintain posture while sitting at the table. These are the systems directly involved with ingesting a carrot.
It contributes because they help us breathe.
Answer:
As you move from red to violet, the wavelength decreases and energy increases.
Explanation:
Here are the 7 from shortest to longest wavelength. Violet - shortest wavelength, around 400-420 nanometers with highest frequency.
hope it helps :)
Answer:
To adapt to the high heat of the desert, the desert kit fox evolved ears with greater surface area, which allows for more efficient removal of excess body heat
Explanation:
As a result of the evolutionary process that occur among the population of species of fox, which most probably must have belong to the same descendant species, the forest kit fox population and the desert kit fox population have become dissimilar in terms of ear size. This divergence can best be explained as a result of the need for the desert kit fox to be better adapted to deal with excess heat in the desert, hence, have evolved larger ears for the purpose of effective losing of excess heat. Heat loss is more effective as a result of larger surface area the ears of the desert kit fox.
The right answer is: controls the movement of substances into and out of cells.
This picture represents a plasma membrane.
The plasma membrane is the membrane that delimits a cell. It separates the cytoplasm from the outside environment.
Special proteins ensure the selective permeability of the membrane (pores), the recognition of chemical signals or carry markers (MHC antigens ...).
The pores are the doors of the membrane. They are macromolecular buildings of protein or glycoprotein nature, sometimes very complex. They are inserted in the bilayer and control exchanges between intracellular and extracellular (with receptors, carriers).
