The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. Teeth are made of dentin and enamel and are part of the skeletal system but are not counted as bones.
Advantages-Spores are covered by a hard protective coat which enables them to survive under unfavourable conditions like lack of water and extreme temperatures.But when the conditions are favourable, the spores grow to produce new plants. This help them to run their species at any type adverse condition or environment.Thus the advantage is that despite of unfavourable environment, their species will not be demolished. Disadvantages-spore formation process is quite primitive.ach spore can survive for a long time since it is covered by a hard protective coat to withstand unfavorable conditions such as high temperature and low humidity. A spore germinates under favorable conditions and develops into a new individual. For example, Plants such as moss and ferns reproduce by means of spores.
Endospores are the resistant and dangerous form of bacteria produced by gram positive bacilli.acterial Spores are a bacterial defensive strategy to survive in harsh environments. Several types of bacteria are capable of using this mechanism. The spores themselves do n â¦ ot cause the disease, they must be first be reactivated to functional bacteria in the proper environment.
