Verified Correct Answer: Option A
Biological Concept & Syllabus Guide
The scapula, or shoulder blade, directly joins the clavicle (collarbone) at the acromioclavicular joint and the humerus (upper arm bone) at the glenohumeral joint.
The scapula bone joins with the clavicle to form the shoulder (pectoral) girdle, which connects the humerus (upper arm bone) with the thorax.

Reproduction in Plants & Animals
Solution
During germination of seeds water is taken by the process of
A
diffusion
B
hydrolysis
C
imbibition
D
translocation
medium Difficulty
Verified Correct Answer: Option C
Biological Concept & Syllabus Guide
The presence of water is the most important factor. Without water, cells cannot carry out their necessary activities and the seed will not germinate. When a seed absorbs water, it is called Imbibition. Water enters the seed either through a tiny opening in the seed called the micropyle or through the seed coat. The micropyle is also the site at which the pollen tube enters the ovule during fertilization.
