Answer:
head of the humerus, Acromial end of the clavicle
Explanation:
The shoulder is made up of three bones: the scapula, the clavicle and the humerus (upper arm bone). Two joints in the shoulder allow it to move: the acromioclavicular joint, where the highest point of the scapula (acromion) meets the clavicle at its acromial end (the sternal end of the clavicle is bounded to the sternon), and the glenohumeral joint. The scapula also bounds to the head of the humerus, it is, the distal superior end.
The Scapula or shoulder blade articulates with the Acromial end of the clavicle, and the head of the humerus, forming the Acromioclavicular and Glenohumeral (Shoulder) joints, respectively.
The Scapula, often referred to as the shoulder blade, forms two primary articulations or joints. These are with the Acromial end of the clavicle and with the head of the humerus.
The Acromial end of the clavicle, or collarbone, connects with the Scapula at the Acromioclavicular joint. The 'head' of the humerus is the ball-like structure at the top of the upper arm bone, which fits into a socket in the Scapula to form the Glenohumeral joint, also known as a Shoulder joint. Therefore, the correct answer is 'Acromial end of the clavicle; head of the humerus'.

B. Today's plethora of microorganisms is the result of an extremely brief period of genetic recombination events.
C. Mutations function to prevent the offspring of an organism from evolving.
D. Random, heritable genetic mutations are a source of genetic variation. This variation is necessary for natural selection to occur.
The statement which is true regarding genes and evolution is as follows:
Thus, the correct option is D.
Genetic mutation may be defined as sudden, stable, and inheritable alterations in the genetic material of an organism. It is considered one of the most useful events for evolution to occur.
Random mutation takes time but they are the least effective and non-influential. Such type of mutations are easily heritable and induces genetic variation among individuals of the same species.
As a result of this, as time passes such mutations become a base for natural selection to occur and allow the favorable variation to survive and reproduce effectively.
Therefore, the correct option for this question is D.
