Sexual reproduction has the advantage of producing genetic diversity in the offspring (as we see it for example in humans) due to the crossing of two gametes of two different individuals as well as the genetic recombination that occur before fertilization.
Of the four propoitions, only one reproduces sexually, and that is the spruce.
The spruce is part of the genus Picea which includes conifers comprising about fifty species.

Wedges is also a form of simple machine and the inclined plane forms its foundation. A wedge can be referred to as the sharp edge of an inclined plane.They are used to level out a structure of an object
Thus we can say that A construction worker uses a hammer to drive a sharp nail into a concrete wall. What two simple machines is the construction worker using when he does this task-(D) a wedge and a lever
Isotonic solution should be your answerrrr
