The type of joint that allows bones to move backward and forward in only one direction is the hinge joints. Ball and socket are the joints that allows movement in all directions. Gilding joints are type of joints that are the vertebral disks that allow twisting, turning, and sliding. Hinge joints are formed between two or more bones where the bones can only move along one axis to flex or extend. They include the ankle, elbow and knee joints.
Answer:
Organism I (circular chromosomes)
Explanation:
I can eliminate organisms II, III, and IV because these organisms have linear chromosomes therefore making it the most closely related to eukaryotes because they consist of linear chromosomes. My only other choice would be organism I, and since it has circular chromosomes we can conclude that this is the most distantly related to eukaryotes.
The organelle in the plant that will most likely store the absorbed herbicide waste is the vacuole. Vacuoles act as storage bubbles in plant cells. They could store various materials such as food or nutrients to help the plant survive. It can also store waste materials to prevent them from contaminating the entire cell.

Answer:
Sternocleidomastoid, pectoralis minor, scalenes
Explanation:
During normal inhalation, contraction of the diaphragm and the contraction of external intercostals expands the chest cavity. The increased volume of the thoracic cavity results in reduced alveolar pressure than the atmospheric pressure to facilitate the flow of air into the lungs in response to the pressure gradient.
During deep inhalation as it occurs when running up the stairs, the accessory muscles of inhalation also participate to increase the volume of the chest cavity. The contraction of scalene and sternocleidomastoid muscles increase the volume of the chest cavity further to create a greater drop in alveolar pressure.
During forceful inhalation, the sternocleidomastoid muscles serve to elevate the sternum, the scalene muscles serve to elevate the first two ribs while the pectoralis minor elevate the third through fifth ribs.
