How does carbon dating tell us how old a bone is ?

Biology
1 answer:
Anestetic [448]3 years ago
5 0

carbon dating shows how old a bone is by measuring the amount of carbon 12, and carbon 14 that the bone contains. and because carbon 14 is not replaced by exchange with the atmosphere the ratio of c12:c14 (the ratio of carbon 12 to carbon 14) tells how old the bone is by comparing the amount of carbon 14 to the amount of carbon 12. carbon 14 has a half life of 5,700 years, while carbon 12 is stable and does not radioactively decay at all.

ANSWER ASAPP<br> Explain the movement of particles in each state of matter.
netineya [11]

Answer:

Gas:

  • assumes the shape and volume of its container ; particles can move past one another
  • compressible ; lots of free space between particles
  • flows easily ; particles can move past one another

Liquid:

  • assumes the shape of the part of the container which it occupies ; particles can move/slide past one another
  • not easily compressible ; little free space between particles
  • flows easily ; particles can move/slide past one another

Solid:

  • retains a fixed volume and shape; rigid - particles locked into place
  • not easily compressible ; little free space between particles
  • does not flow easily ; rigid - particles cannot move/slide past one another

Particles in a:

1. gas are well separated with no regular arrangement.

2. liquid are close together with no regular arrangement.

3. solid are tightly packed, usually in a regular pattern.

Particles in a:

1. gas vibrate and move freely at high speeds.

2.liquid vibrate, move about, and slide past each other.

3. solid vibrate (jiggle) but generally do not move from place to place

hope that this helps :)

Suppose no crossing-over takes place. Use step 5 (anaphase 1) to explain why meiosis will still increase genetic variation.
MissTica

Meiosis increases genetic variation due to random segregation which occurs.

In anaphase I of meiosis, the homologous pairs (one maternal and one paternal chromosome) are moved apart to opposite ends of the cell and this process occurs random. This allows the formation of gametes with different sets of homologues. In this phase sister chromatids remain attached at their centromeres (not segragated as in mitosis).

These ____________ group together to eventually form ____________ , or the basic units of all living things.
Sedaia [141]

These organelles group together to eventually form cells, or the basic units of all living things.

Organelles are specialized structures in the cytoplasm of cells which provide essential cell functions and are composed of different molecules (macromolecules). Cells as the smallest basic units of life are then grouped in tissues (similar cells which provide a specific function), layers of different tissues work together to provide specific function and form organ, organ group in organ systems which then compose the whole organism.
