I am thinking the rock that forms from lava that cools quickly is D) Obsidian.
All their children will have heterozygous genes because squidward is "purebred", or homozygous dominant. His wife has to be homozygous recessive for a recessive trait to show up. Every time you cross a homozygous dominant trait with a homozygous recessive trait, you will get heterozygous kids. This means all of them will have light blue skin.
Answer:
Nuclear decay rates are constant
Explanation:
Spontaneous decay of unstable nuclei is a process of a statistical nature, it is not possible to predict with certainty when an individual radioactive nucleus will decay, nor can the decay process be influenced in any way.
Therefore, the half-life of radionuclides (specific for each radionuclide) is defined as the time period in which half of the initial number of radioactive nuclei decays.
The unit of measurement for the radioactivity of the material is the becquerel (Bq) and denotes the number of decays in one second (1Bq = 1 decay / 1 second).
The branch of biology dealing with interactions along organisms and between organisms and their environment is called Ecology, I believe.
