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
Explanation:
Simple machines are the tools an individual uses in his day to day life in order to make its work simpler.
For Example: Axles and wheel make it simple to carry a heavy object in a shopping cart.
<u>A hammer is a type of lever,</u>and is also a type of simple machines.A hammer can be defined as a heavy rigid bar moves around a fixed point ,that point is called fulcrum .
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

Species strategies to survive and successfully reproduce define three basic survivorship curves. <em>The survivorship curve </em><em>type III</em><em> is the one that best represents the Dandelion plants.</em>
------------------------------
According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,
<u>Type I.</u>
- Mortality often occurs at the end of the cycle, representing species with low mortality.
- Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough.
- These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.
<u>Type II.</u>
- The probabilities of dying are equals all along the cycle, at any age interval.
- The number of dead individuals remains constant from the beginning to the end of the life cycle.
- These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.
<u>Type III.</u>
- Significant mortality during the early stages of life.
- Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.
- These species produce large offspring at the same time, but they provide little or no parental care.
- The reproductive success of these species depends on the number of descendants and not on the parenting time spent.
According to this information, and the characteristics of the <em>Dandelions, we might assume that this species is represented by type III curve.</em>
