Answer:
Mutation
Explanation:
Mutations can be defined as changes in genetic material, which are the main source of existing genetic variation. For ensuring genetic variability, that is, ensuring that individuals have different DNA, mutations are considered an important point in the evolution of living beings.
It is through mutations that important adaptive characteristics emerge, in addition to essential characteristics remaining in species that are different but that have similarities.
These processes also guarantees the selection of species most adapted species. Mutations can be beneficial, neutral or harmful (genetic diseases or genetic "failures") and, therefore, are not targeted, occurring at <u>random</u>.
Co-dominance since both traits show up equally.
The slowing down of the ray of light also causes the light to change direction
Answer:
When fluids (liquids and gases) are heated, they expand and therefore become less dense. Any object or substance that is less dense than a fluid will float in that fluid, so hot water rises (floats) in colder water.
Explanation:
When you heat up water, the water molecules start moving around faster and faster. ... So hot water is less dense than cold water. When you put the two together with the hot water on the bottom, the hot water rises to the top.
