Answer:
The correct answer is option C) "comparison of DNA sequences of primates".
Explanation:
Before DNA analysis was available, biologists took different approaches to construct evolutionary trees among the species. However these approaches were inaccurate and produced variabilities, such as the one constructed by St. George Jackson based on spinal columns analysis and the other tree based on limb comparisons. Nowadays, comparison of DNA sequences is the most widely and accepted method to generate evolutionary trees for being a highly accurate and reliable source to establish common ancestors among species.
Answer:
the egg yolk is the Earth's inner core
the egg white is Earth's outer core
the egg shell is the mantle
the cracked pieces of egg shell is the lithosphere
the entire egg is earth
Explanation:
I'm not sure about all of these, but it should hopefully be correct. I'm not sure about what the whole egg would be. I hope this helps you anyways :)
Doing so is an example of using biology to improve human health.
If someone had an inadequate intake of sodium over several days, it would be most difficult for the body to maintain homeostasis.
<h3>Why is sodium important for homeostasis? </h3>
Most of the sodium in our body is present in the extracellular fluid (ECF). The concentration of sodium in the body is measured relative to the amount of water in the body.
Maintaining proper sodium concentration is therefore essential for maintaining water balance in the body. It also helps in the proper functioning of neurons by assisting in the conduction of impulses.
Sodium concentration is also important for muscle contraction. Proper sodium concentration maintains osmolality of the extracellular fluid which maintains the volume of blood and plasma in the body.
Therefore, an inadequate intake of sodium, over several days will affect the homeostasis of the body.
