How are the Hawaiian honeycreepers an example of adaptive radiation?
There were a large variety of honeycreepers that first inhabited the island. They found many different niches, so they were all able to survive.
The honeycreepers that first inhabited the island were able to adapt as the island changed, so that population of birds was able to survive.
There was a diversification of honeycreepers (each with different beak shapes) to help fill various ecological niches.
Answers
Answer: In adaptive radiation, many different species evolve from a single ancestor species. Each new species evolves to exploit a different niche, such as food source. In the example above, Hawaiian honeycreepers evolved a range of bill forms in response to available food sources on the Hawaiian archipelago. The honeycreepers dispersed from one founder species, and evolved in response to natural selection based on different food sources in their isolated habitats provided by water. Seed-eating birds evolved thick, short beaks.

Identify ONE process that causes the metamorphism of an igneous rock into a metamorphic rock.
Answers
Answer:
Heat
Explanation:
Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.
Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.
What is metamorphic rock?Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.
Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.

The nucleotide bases are always bound to each other in a complementary form, i.e. A is bonded to T with the help of two hydrogen bonds, while C is bonded to G with the help of three hydrogen bonds.
Apart from this, according to Chargaff's rule, the amount of adenine is always equal to the amount of thymine, while the amount of guanine is always equal to the amount of cytosine.
Therefore, it is well described above.

1) The male frogs croak to attract mates. They can also visually attract females by displaying vibrant colors. They compete by comparing who calls louder
2) This aids in survival because this ensures that only healthy frogs get to pass down their genes. Unhealthy frogs will not be selected by females. This is called sexual dimorphism
3) The hummingbird displays its impressive tails which they move around to attract females. They may perform aggressive movements against other competing males.
4) These strategies are very important to maintain a diverse and healthy population in a community of animals.

Describe how people change their body shapes (not their clothes) when they are very hot and when they are very cold. Use your knowledge of surface area : volume ratios to explain why we do this.
Answers
Answer:
This quesiton is unclear
Explanation:
The body has negtive feedback loops that either vasoconstrict (preserving heat by lessening the surface area of blood vessels so they are exposed to less cold and release less heat) and vasodilation, where blood vessels are expanded and have higher surface areas so the body hopes to lose more heat to cool down.
If this is purely body language (like going into a fetal position when its cold: to lessen the surface area exposed to the cold temperature and lose less heat, imagine an ice cube vs. a long thin tube of ice with equal volume, the cube will last longer. Similarly our bodies would spread out to release more heat (unless there was sun) this is to expose the most surface area, allowing our body to release the most heat. Note: this is pretty insignificant change, and in extreme temperatures will likely not help, but it does contribute.
