Answer:
Natural selection is an important contribution to the theory of evolution because it increases an individual's ability to survive and compete and reproduce.
Explanation:
Answer: pH = 9.4
Explanation: in water, -log(molar concentration OH-) + -log(molar concentration H+) = 14
-log(H+) is pH
so pH = 14 - -log(OH-)
= 14 - -log(2.4*10^-5)
= 14 - 4.6
= 9.4
Answer: pubic symphysis
Explanation:
The amphiarthrosis is the joint which shows limited mobility. This joint is a kind of cartilaginous joint which unites the body of two vertebral bones.
The amphiarthrosis articulation can be seen at the pubic symphysis of the pelvis. This cartilaginous joint strongly anchors the pubic region of the right and left hip bones. This region exhibit restricted mobility. The strength of this region helps in the weight-bearing stability of the pelvis during pregnancy.
Plants often go into the dormant state to protect themselves from suboptimal conditions (usually harsh winters). A tough outer covering can protect the plant from freezing, the buds are covered for this same reason. The leaves fall to minimize the loss of energy since in the winter there is usually not enough sunlight to sustain the process of photosynthesis.
