Answer:
Incorrect
Explanation:
In the bone modelling process, osteoblasts a responsible for bone formation and osteoclasts are responsible for bone resorption. In the young adult during growth, the formation of bone exceeds the resorption of bone to maintain bone mass. Therefore,
As we get older, bone formation decreases due to reduction in osteoblastic activity and numbers and bone resorption increases as a result of sex hormone deprivation, this will result in decreased bone mass (osteoporosis). Therefore, osteoclastic activity would have to exceed osteoblastic activity in order or osteoporosis to develop
The answer is C Good luck

Answer:
The correct answer would be "The female cone releases its seeds and new sporophytes grow".
Conifers are sporophytes with two types of cones; pollen cones and ovulate cone.
The pollen cones are smaller in size and produce microspores which would develop into the pollen grains.
The ovulate cones are larger in size which produce megaspores which would develop into ovule.
The two gametes fertilized to produce a diploid zygote which develops into the embryo.
The fertilization takes place in the ovule and thus, embryo or seed is developed in the female cone.
The female cone then releases its seed which grows into a new sporophyte.
