Answer:
The correct answer is B. clavicle articulates with the manubrium of the sternum.
Explanation:
The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. The sternal end is also anchored to the first rib by the costoclavicular ligament. The medial end, also known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.
Answer:
reduction in potential medicines
reduced food supply
Explanation:
The direct consequences of a decrease in angiosperm's biodiversity is a reduction in potential medicines and food supply.
Angiosperm biodiversity (the flowering plants) act as a source of food to several living organisms, including human. This is evident in the practice of farming by humans. Different categories of consumers in the ecosystem depends largely on flowering plants for their food either directly or indirectly.
They also serve as a source of medicine. For example, chloroquine which use to be the major drug against the treatment of malaria was extracted from a flowering plant known as <em>Chinchona pubescens.</em>
<em>Several species of flowering plants remains in the wild whose usefulness are yet to be researched. They represent a source of future food and medicine for man and animals.</em>
<em>Hence, if the diversity of flowering plants is reduced, it is going to have direct consequence of reduction in potential foods and medicine.</em>
