When cells communicate by the signaling process, one cell produces a _________________BLANK that must be received by the _______

velikii [3]

Answer:

1. Signaling molecule

2. Signaling receptors

Explanation:

Hormones, growth factors, neurotransmitters, etc. serve the function of signaling molecules for cells. These molecules are released by one cell and bind to the receptors present on/in the target cells to elicit the desired response. Thereby, the signaling molecules serve in cell-cell communication.

For example, insulin hormone synthesized and released from beta cells of pancreas binds to its cell surface receptors present on the surfaces of liver cells and muscle cells to stimulate the uptake of the glucose from the blood.

Likewise, neurotransmitters released from the presynaptic neuron bind to receptors present on the membrane of postsynaptic neuron and serve to carry the nerve impulse to the postsynaptic neuron.

An amoeba reproduces by splitting itself into two amoebas. This means that the original amoeba dies and its two offspring live o

Naddika [18.5K]

Answer:

If one amoeba dies then two amoeba get born:

at different stages of the generations of the amoeba it changes accordingly and the died amoeba numbers are also change in the given manner :

stages dies born

I 1 2

II $2^{1}$ 4 = $2^{2}$

III $2^{2}$ 8 = $2^{3}$

At $n^{th}$ = $2^{n}$ $2^{n+1}$

By the geometric series formula:

1+ $a^{1}$ + $a^{2}$ + $a^{3}$ ...+ $a^{n}$ = $\frac{a^{n+1} }{a^-1} }$

so, 1+ $2^{1}$ + $2^{2}$ + $2^{3}$ ...+ $2^{n}$ = $\frac{2^{n+1} }{2^-1} }$

Thus, total amoeba died = $2^{n+1}$ -1

total amoeba died+1 = $2^{n+1}$ (born).... hence prooved

What parts of atoms are responsible for how they interact with other atoms

weqwewe [10]

The correct answer is outer electrons. These are sometimes called 'valence electrons', and they are responsible for the element's properties and how it forms bonds. For example, elements in Column 2 are likely to form ionic bonds with elements in Column 16. This is because elements in Column 2 have 2 outer electrons, while elements in Column 16 have 6 outer electrons. If the element in Column 2 gives its 2 electrons to the element in Column 16, then the former will be stable because the energy level underneath will be complete, and the latter will be stable because it will have a complete outer energy level with 8 electrons.

Hope this helps!
