Answer:
The molecule on the right; the middle carbon is asymmetric
Explanation:
The answer could be either B or D. Both are important for marine biology. I would have to say D is the best answer though!
Answer:
Explanation:
Cell specialization is also called cell differentiation. Through this process, specialized cells form from the unspecialized cells. Then many cells are formed and determined to form specialized functions.
The stem cells are the unspecialized cells which form a different kind of specialized cells.
The muscle cells, nerve cells, sperm cells, red blood cells are specialized cells perform different specialized functions. All these cells arise from stem cells. The nerve cells receive impulse, muscle cells can contract, etc.
There are certain inductive signaling genes that send the signal to the differentiated cells. These signaling molecules are called ligands. These ligands move to another cell to produce specialized cells. In other words, there are some transcription factors and genes responsible for such cell differentiation and the formation of specialized cells.
Another example is zygote, which is an unspecialized cell. This is also a totipotent cell that has the potentiality to reproduce different cells.
Only Bone marrow. intra crinal nervous muscle and joint
Missing choices:
a) Calcium entry into the sarcoplasm, calcium binds to troponin, muscle contracts, closing of calcium channels, calcium released from troponin, muscle relaxes
b) Calcium entry into the sarcoplasm, muscle contracts, calcium binds to troponin, closing of calcium channels, calcium released from troponin, muscle relaxes
c) Calcium entry into the sarcoplasm, calcium released from troponin, muscle contracts, closing of calcium channels, calcium binds to troponin, muscle relaxes
d) Calcium entry into the sarcoplasm, closing of calcium channels, calcium binds to troponin, muscle contracts, calcium released from troponin, muscle relaxes
My answer: d) Calcium entry into the sarcoplasm, closing of calcium channels, calcium binds to troponin, muscle contracts, calcium released from troponin, muscle relaxes
