Answer:

pH is really a measure of the relative amount of free hydrogen and hydroxyl ions in the water.

What does cell specialization in multicellular organisms aloows cells to do?
weeeeeb [17]

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.

kari74 [83]

Answer:

Explanation:

We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
