Based on study of Finches in the Galapagos islands, finches with beaks sizes better suited to their environment survived while those not suited died in a process of natural selection.
What is natural selection?Natural selection is a natural process that occurs in which organisms which are better suited to their environment are selected for survival and reproduction.
The study of Finches in the Galapagos islands demonstrated natural selection.
One trait that demonstrates the genetic variation of finches of the Galapagos Islands is their beaksize.
The changes that occurs in the beak shape and size of the Finches were adaptations to enable them survive.
Finches with beaks that helped them adapt to changes in their environment survived while those that lacked these adaptations did not.
Therefore, organisms better suited to their environment will survive while those not suited will die in a process of natural selection.

Answer: Bacteria and fungi employ a variety of mechanisms to increase soil organic matter and function, but they do so at the expense of maintaining a healthy population in the soil. Bacteria contribute to ecosystem health by decomposing dead matter and cycling nutrients into useable forms. Bacteria may be found in all habitats and produce the majority of the oxygen on the planet. Bacteria are decomposers in the soil that break down organic compounds.

What is the best example of how nervous system maintains homeostasis
Answer:
The nervous system regulates breathing and heartbeats but it's also responsible for regulating the core temperature of the body. So when conditions are too warm or hot and body temperature rises, the blood vessels can dilate causing heat loss. Nerves can trigger sweat glands to release fluid that evaporates and cools the skin so that body temperature begins to lower to a normal condition.

A low water concentration means a
solute concentration
high
low
Answer:yes
Explanation: when the concentration of a solute is high, the concentration of water is lowered since there is more solute per water, less water per solute. Thus, when water moves from low concentrations of solute to high concentrations of solute, it moves from high concentrations of water to low concentrations of water.
Answer:
high
Explanation:
If the concentration of the water is low ten that means the solute-solvent ratio is high which means the solute(solid dissolved) is high
