A student wants to prove that amphibians appeared on earth before birds. The student should use the fossil findings as evidence to provide the most reliable information about the periods when amphibians and birds appeared on earth. Fossils would throw light on the internal body structures that bear the closest similarity to either the amphibians or the birds. The radiocarbon dating of the fossils will reveal its age. This can be used to figure out the time of divergence of the two types.
Lysosomes are organelles that float on the cytoplasm and their main function is to secrete waste out of the cell and digest.
Lysosomes are found in eukaryotic cells and yes, they are present in plant cells.
Hope it helped.

Answer:
For this receptor, the stimulus begins with an explosion of action potentials.
that would be the correct option.
Explanation:
A tonic receptor is one that is activated when the action potentials were maintained over time and during the signaling of the receptor.
Tone receptors require continuous stimulation over a period of time to trigger a response and deliver it to the central nervous system.
It keeps the nervous system constantly active in the environment that surrounds it.
They are slowly adaptable, an example of these receptors are the merkel and ruffini receptors.
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions
Answer:
Carrying capacity, or the greatest number of people that an environment can support over time without harming or degrading it, is controlled by a few basic factors: food supply, water availability, and space.
