Explanation:

The ability of a metal to be drawn out into thin wires is a physical property present in Option 4 because the composition remains constant, but it is this property that causes the metal to be drawn out into thin wires.

The metal has the ability to form thin wires; this is known as "ductility" and can be seen in gold, for example; this is a physical property of the metal. The physical change involves a change in shape and size, and the transition from one state to another is seen. Chemical change is related to the chemical composition of the substance.

Hence, the ability of a metal to be drawn out into thin wires is a physical property present in Option 4 because the composition remains constant, but it is the property that causes the metal to be drawn out into thin wires.

Answer:

Geography affects the weather in many ways. ... Topographical features like mountains affect the weather mostly in the way that they direct air currents. For example, air is forced to rise over mountains. Moist air will cool as it rises, and then the clouds release the water, causing precipitation like rain or snow.

Explanation:

Plants and animals need to coexist in order to thrive. Plants need animals just as much as animals need plants. A simple example of this would be trees. Trees provide many things to many different organisms but I will use shelter as an example. Trees provide shelter to many animals such as birds, so in essence they protect birds. Birds eat plants and in turn spread the seeds which grow. Insects, like bees, collect pollen from the flowers, etc. It is all part of a complex system in which species all depend on one another for some specific reason. So, interdependence is when plants and animals depend on each other for survival.

In general, the interdependency of organisms extends ecologically to their environment. Organisms rely on each other to sustain the ecological environment, something that humans have been lacking in. So, in general, organisms are interdependent because they have no choice.

Answer: There are many examples of recessive traits in non-human animals as well. In dogs, traits like yellow fur, white spots, and smooth hair are recessive. In cats, white fur, brown (as opposed to black) fur, and long hair are recessive traits. In sheep, black wool and blue eyes are recessive.

Also Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

D) Earth's internal heat is thermal energy generated from radioactive decay and continual heat loss from Earth's formation.

Explanation:

The geothermal energy of the Earth's crust originates from the original formation of the planet and from the radioactive decay of materials. The geothermal gradient, which is the difference in temperature between the core of the planet and its surface, drives a continuous conduction of thermal energy in the form of heat from the core to the surface.
