The function of the lens is that it allows light rays to focus into the retina. They are composed of fluids that contains lots of nutrients for the lens to gain from it and cleanses dirt if it comes in contact the eye. Overtime, this lens, will slowly degrade as its fluid will start to lose.
Answer:
A
Explanation:
Genetic variation means difference in organisms. If they are identical, they are not different, and therefore there is no variation.
Explanation:The rock cycle is a model that describes how rocks are created, changed, and broken down. There are three major types of rock: igneous rock, metamorphic rock, and sedimentary rock. During the rock cycle, each type of rock may be changed into another type.
The rock cycle includes these processes:
Crystallization is the process by which magma cools and forms solid igneous rock.
Heat and pressure can change igneous rock and sedimentary rock into metamorphic rock.
Weathering and erosion are the processes that break down rock into sediment and transport this sediment to other places.
Sediment is changed into sedimentary rock by compaction and cementation.
Melting is the process that transforms solid rock back into liquid magma.
1. Because the increase of temperatures.
2. Why they effect humans - Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
2. Why they effect the ecosystems - Continual melt from glaciers contributes water to the ecosystem throughout dry months, creating perennial stream habitat and a water source for plants and animals. The cold runoff from glaciers also affects downstream water temperatures.
