Two lakes are close to one another and sometimes connect when floods occur. Each lake has two species of fish that are very similar. One species has brown scales and the other species has orange scales. One hypothesis for the origins of the fish species is shown below. What does this hypothesis state?

A. The fish in Lake 1 and Lake 2 come from different types of ancestors.

B. The fish in Lake 1 and Lake 2 originally lived in the same lake.

C. The fish in Lake 1 and Lake 2 are descended from a common ancestor.

D. The fish in Lake 1 and Lake 2 developed due to geographic separation.

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.

Explanation:

Balanced forces do not result in any change in motion while unbalanced forces result in a change in motion.

Answer:

reduction of gene flow can occur due to geographical isolation too

or it can be dur to sympatric or allopatric speciation an occur.

where due to this the species are being behaviouraly isolated, and mad too reject mating due to certain reasons. Moreover mutations too can take palace causing for a genetic drift. Where the isolated species may undergo selection pressure too. So as an overall view the gene flow eventually decreases since the species diversity along with the genetic diversity decreases causing fare the reduction of the gene pool.

After many generations a new species will be formed. Resulting for speciation.

(refer to the AL biology text book under biodiversity related topics, it will be easy)

Answer:

plants grow best in sandy loam

The full question is:

As of the year 2000, the human population was approximately _______.

Answer: D

Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species could lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.

A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.

D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.

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.

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.

Answer:

Magma heats nearby rocks and underground aquifers. Hot water can be released through geysers, hot springs, steam vents, underwater hydrothermal vents, and mud pots. These are all sources of geothermal energy. Their heat can be captured and used directly for heat, or their steam can be used to generate electricity.

Answer:

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.
