Answer:
e) are continuously modified so that they are always matched to the environment in which a population lives
Explanation:
The role of natural selection is to select individuals best adapted to a given ecological condition, allowing them to survive and leave descendants in a given environment.
Natural selection acts permanently on all populations. Even in stable and constant environments, natural selection acts in a stabilizing manner, is present, eliminating divergent phenotypes.
However, the environment does not represent a constant and stable system, in fact, it is always changing, both over time and throughout space, which determines different interactions between organisms and the environment.
Answer:
A
Explanation:
These are the properties of an acidic solution. The higher the H+ ions in the solution the higher the acidity. H+ is also a measure of pH because pH is the negative log of the H+ ions in a solution. The more the H+ ions, the lower the pH of the solution. The H+ ions also allow the solution to conduct electricity because they take up the electrons and transport across from the anode to the cathode. Acidic solutions are also corrosive because they are highly oxidizing – the H+ ions accept electrons to turn to H₂ gas.
Answer:
In science, a model is a representation of an idea, an object, a process or a system. Using a plastic bag, students can model the water cycle. ... When the plastic bag is hung in a sunny window, heat from the Sun evaporates water from the lake and forms condensation and precipitation.
A bonds with T and C bonds with G.
Proteins are made inside cells. When a cell makes a protein it is called protein synthesis.
