Continental drift is the movement of Earth’s continents over long periods of time. An evidence for this is that some continents look like puzzle pieces that can fit together, such as South America and Africa. Another evidence is that fossils of the same type have been found in different continents, far apart - suggesting that the two continents once were joined. Another evidence is that identical rocks were found at both sides of the Atlantic Ocean by Alfred Wegener, the main developer of the continents drift theory.
The mass of an element listed in the Periodic Table is the weighted average of all its naturally occurring isotopes.
Naturally occurring carbon is about
99 % carbon-12 (12.000 u) + 1 % carbon-13 (13.003 u).
That extra carbon-13 makes the <em>average atomic mass</em> greater than 12.000 u.
Answer:
C. it will have more photosynthesis if it gets more sunlight
Explanation:
The amount of sunlight is crucial for what kind of an ecosystem will develop. This is because the sunlight is what enables the development of the producer communities. The producers use the sunlight in order to perform photosynthesis, so the more sunlight there is, the more photosynthesis they will perform. If there is lot of sunlight, then there will be an abundance of producers in the ecosystem, and since they are the basis of any ecosystem, there will be lot of consumers as well, thus the ecosystem will have an abundance of species from every trophic level.
There are questions about the external validity of the results because single-subject experiments frequently only involve a small number of subjects.
<h3>What is experimentation with a single subject?</h3>
A type of quantitative research known as single-subject studies includes closely examining each participant's behavior in a small sample size. It should be noted that the phrase "single-subject" does not necessarily suggest that only one participant is being examined; rather, it usually refers to a group of two to ten.
<h3>What does a single-subject research design aim to achieve?</h3>
Single subject research design is a sort of research methodology that involves monitoring a single phenomena repeatedly over time (often a behavior), and it is typically used to test interventions.
<h3>What features distinguish single-subject studies?</h3>
Changes on the DV can be measured using data gathered before, during, and after the intervention.
