A. Amber, because in the Prehistoric times the insects and small dinosaurs fell into amber and became preserved in the hardened sap.
The answer is 1. domain, 2. kingdom, 3. phylum/division, 4. class, 5.
order, 6. family, 7. genus and 8. species. From largest (first) to
smallest (eighth) taxa, the order is following: domain, kingdom,
phylum/division, class, order, family, genus and species. Taxonomic
groups, or taxa, are used for biological classification. For example,
for human, the classification will look like this: 1. Domain: Eukarya;
2. Kingdom: Animalia; 3. Phylum: Chordata; 4. Class: Mammalia; 5. Order:
Primates; 6. Family: Hominidae; 7. Genus: Homo; 8. Species: Homo
sapiens.
Answer:
The correct answer is - option B. The presence of pups is the independent variable, and the frequency of sentinel behavior is the dependent variable.
Explanation:
The independent variable in a study or experiment is a variable that is subject to change or manipulated to see the effect on the result of the study by influencing the dependent variable. In this study, the independent variable that is manipulated is the presence of the pups to see what is led to the behavior of meerkats.
The dependent variable is a variable that is influenced in a study by the independent variable and led to the result of the study as the frequency of sentinel behavior is influenced by the presence of the pups so the dependent variable here is the frequency of sentinel behavior.
Atmosphere? I am not really sure what you are asking.
