Can parent's go too far in supporting their children's dreams
motikmotik
Yes,  of course! They may not always realize that instead of helping sometimes they're harming.  They could push their child into a school that can help them for the future even though they want to try a different school. They can annoy their child and they'll get sick of it and lose interest in their subject.

Atoms can have different numbers of which of the following electrons, protons neutrons or all of the above
OLEGan [10]
Atoms may have different numbers of neutrons. Atoms are the smallest fraction of an element that can exist, and still show the properties of the element. They consists of electrons (negatively charged), protons (positively charged), and neutrons (no charge). The number of electrons is equivalent to the number of protons normally however an atom may loose or pick up electrons and  have a positive charge or negative charge. The number of neutrons in the nucleus may vary within a given element to give varieties of atoms we call isotopes.

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.
