<span>It may be difficult for ecologists to determine the size of a bird population if that population migrates to different locations throughout the year. During migration, some birds may split off from the group and not return, others may die, and still others may join. Therefore, the bird population will be in constant flux. It is hard to know, when the birds return to their prior location, if the population consists of the same group of birds (in addition to deaths and births) or whether it has grown or shrank through other means. However, to estimate the size, an ecologist can track a migratory flock through several years, counting each year to get a general sense of the population size. Additionally, given one measurement, an ecologist could consider the average lifespan and birth rates of the population to extrapolate the size of the population in subsequent years.</span>
Answer:
lysosomes, small molecules
Explanation:
-plants:usually not evident Animals: occurs in cytoplasm
-small organelles filled with enzymes
-"clean up crew"
- the digestion or breakdown of lipids, carbs, and small proteins into small molecules that can be used by the rest of the cell
-involved in breaking down organelles that have outliveed their usefullness
-diseases are trace to lysosomes that dont function properly
Based on that scenario, a faulty reasoning that the student's research advisor most likely point out is : The rock that makes up the fossils replaced the organisms tissue and genetic material,
Because of this , their genomes can't be extracted.
hope this helps
