Answer:
For example, if the seeds that the bird needs to eat is bigger, over time it will adapt to get a bigger beak to eat the bigger seed. The birds that have adapted reproduce and soon more and more birds that have a bigger beak for the bigger seed are more common. If the type of food available changes than the bird will most likely adapt to eat that food.
Answer:
C2H2O4
Explanation:
<em>The molecular formula can be derived through the below analysis.</em>
Two black balls (C) bonded to each other at the center = C2
Single-bonded red balls (O) bonded to white balls (H) above left and below right = (OH)2 = O2H2
Double-bonded red balls above right and below left = O2
Adding the three together = C2 + O2H2 + O2 = C2H2O4
The correct answer is C2H2O4
Answer:
Earth has various layers: the covering, the mantle, the fluid outer core and the inner core.
The Earth's attractive field controls the course and speed at which Earth's internal and external centers turn, despite the fact that they move in inverse ways, new research proposes.

Case studies do not allow for replication. So, the correct option is (b).
Case studies are investigations that compile in-depth information about a person or group. They employ a wide range of research techniques, including observations, interviews, case studies, and personality tests, to collect the data. They can frequently collect both qualitative and quantitative data thanks to this. Research can be cross-sectional or longitudinal, which lasts for a long time.
It enables a researcher to thoroughly explore a subject. Case studies are unreliable because they cannot be duplicated and hence cannot be reliability tested. Any data acquired cannot be used to make generalisations because the outcomes are specific to the time, event, setting, and individual.
