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.
Answer:
The right answer is Option A. It filters the blood that is used by the excretory system.
Explanation:
The endocrine system has great affect on the excretory system. It gives massages to the excretory system. When the amount of water is exceed in the body, the endocrine system send massage to the excretory system to produce more urine. And when the body has less amount of water, the
endocrine system send massage to the excretory system to produce less urine.
Two decades ago, while researching her doctoral thesis, ecologist Suzanne Simard discovered that trees communicate their needs and send each other nutrients via a network of latticed fungi buried in the soil — in other words, she found, they “talk” to each other.
Answer:
They are organisms (individual organisms called "plankters") that live in large bodies of water.
Explanation:
They reside in large bodies of water (oceans, lakes, etc). They are usually abundant in surface waters because all ecosystems of plankton live off input of solar energy.
