25% would have tay-sachs disease, 25% normal, 50% carriers
93AU from the surface of the sun, or the third planet out from the surface of the sun.
The answer is ‘behavioral isolation’. It is a form of
sympatric speciation - which occurs even when
species live in the same habitat. In this case,
the individuals in the population are isolated by differences in mating and probably different mating rituals.
Answer:
Water is slower to heat than most materials.
Explanation:
There is a physical property called "specific heat". This property determines the amount of temperature necessary to change 1ºC in the temperature of the materials. The higher the specific heat of the material, the slower it will heat up.
The water has an extremely high specific heat, which means that it will slowly heat up to an extremely high temperature. The specific heat of the water is greater than most materials and this explains why high variations and external temperature changes almost do not cause changes in the water of the picisnas, for example.

use the bioluminescence to attract mates for mating hence key in reproduction.
Therefore, beetles from different species should have different lighting
patterns so that they can only attract mates of the same species. This would
avoid interspecies mating which would probably involved expending energy in
produce nonviable offspring which is inefficient (hence will be unfavoured
natural selection). </span>
