The presence of palpable lymph nodes.
Lymph nodes are relatively large in children, and the supperficial ones often are palpable even when the child is healthy.
The two organelle that convert energy into plants are Chloroplasts and Mitochondria.
The limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.
<h3>What is population dynamics?</h3>
Population dynamics is the part of ecology that studies the variations in the occurrence of individuals of the same species (population) and seeks to define the cause of these variations.
Example: with the hunting of alligators, there is an increase in the population of piranhas, thus resulting in a variation of occurrence.
With this information, we can conclude that the limitations of population dynamics simulation in predicting the changes that may occur due to climate change is that arctic seals can adapt to these climatic conditions or migrate.

Answer:
A. Rock pieces
Explanation:
Abrasion is the breaking down and wearing away of rock material by the mechanical action of other rocks. Three agents of physical weathering that can cause abrasion are moving water, wind and gravity. None of those are agents of abrasion. But Rock pieces are a result of abrasion.
