Answer:
<u><em>The correct option is the presence of a specific hormone receptor.</em></u>
Explanation:
Every cell membrane contains certain cell surface receptors which detect an extracellular molecule and allow it to perform function inside that particular cell. The cell surface receptors receive and transmit signals.
For a specific hormone to function inside a particular cell, the cell must possess a specific hormone receptor embedded in the plasma membrane which will detect the hormone and allow it to function inside the cell.
Answer:
Bacteria.
Explanation:
When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle. Denitrification - Extra nitrogen in the soil gets put back out into the air.
In assessing for complications in a client who has been using crutches for two weeks, the finding that is most important is the hand and wrist weakness which is number three because this is the part of the body that exerts the most effort because it supports the crutches in order for the body to move. And if it is weak, it could be a problem to the client using crutches.
Answer:
In addition to biology, evidence drawn from many different disciplines, including chemistry, geology, and mathematics, supports models of the origin of life on Earth. In order to determine when the first forms of life likely formed, the rate of radioactive decay can be used to determine the age of the oldest rocks (see optional problems C and D, below) exposed on Earth’s surface. These are found to be approximately 3.5 billion years old. The age of rocks can be correlated to fossils of the earliest forms of life. A. The graph compares times of divergence from the last common ancestor based on the fossil record with a "molecular time" constructed by comparing sequences of conserved proteins to determine a mutation rate (after Hedges and Kumar, Trends in Genetics, 2003). Explain how such a molecular clock could be refined to infer time or the evolution of prokaryotes. B. Using a molecular clock constructed from 32 conserved proteins, Hedges and colleagues (Battistuzzi et al., BMC Evol. Biol. 2004) estimated the times during which key biological processes evolved. A diagram based on their work is shown. Connect the time of the origin of life inferred from this diagram with the age of the oldest fossil stromatolites and the age of the oldest exposed rock to show how evidence from different scientific disciplines provides support for the concept of evolution. Evaluate the legitimacy of claims drawn from these different disciplines (biology, geology, and mathematics) regarding the origin of life on Earth. The oldest known rocks are exposed at three locations: Greenland, Australia, and Swaziland. The following application of mathematical methods provides essential evidence of the minimum age of Earth.
Explanation:
False. I don't know how to explain it but they don't classify as living.
