Answer:
Convergent Evolution
Explanation:
Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.
An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.
Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate
.
When Sarah performed this experiment, she changed the levels of nitrogen in order to observe the changes in the morphological features of the plant.
All of the characteristics of the plant that she observed were dependent on multiple different things, but the level of nitrogen was an independent variable that she was changing at her will.
The item produced when a yeast cell undergoes fermentation is ethyl alcohol. The correct answer is A.
Answer:
Through a circumstance known as "secondary transfer DNA", or "Touch DNA".
Explanation:
Most times when a crime is committed, DNA samples are obtained from surfaces in the scene where the crime was committed. There is a very huge possibility of picking up the DNA of someone who was never at the scene of the crime and this is a result of a condition known as Touch DNA.
Because we touch several objects which can be moved to different locations and touch people who are also always mobile, our DNA cells can find their ways to a crime scene where we had never physically been to. This can lead to false verdicts of guilt.
Alliances fall into two broad categories: contractual (non-equity) and equity-based.
projects, strategic suppliers, strategic distributors, and licensing/franchising (see Chapter 6 for
definitions). These are also limited in scope and duration.
Equity-based alliances call for a higher level of commitment. Examples include strategic
investment (one partner invests in another as a strategic investor) and cross shareholding (both
partners invest in each other). A joint venture is a special case of equity-based alliance that
establishes a new legally independent entity (in other words, a new firm which is the JV) whose
equity is provided by two (or more) alliance partners.
Although JVs are often used as examples of strategic alliances,
not
all strategic alliances are JVs.
Essentially, a JV is a “corporate child” given birth by two (or more) parent firms, such as
SonyEricsson’s set up by Sony and Ericsson. A non-JV, equity-based alliance can be regarded as
two firms “getting married,” but not having “children.” The Renault-Nissan alliance is such an
example.
Networks are also a form of strategic alliance. For the purposes of this chapter, we define
strategic networks as strategic alliances formed by multiple firms to compete against other such
<span>groups and against traditional single firms</span>
