During meiosis, homologous chromosomes line up next to each other. In some
cases, one arm of a chromatid crosses over the arm of another chromatid. What is
the result of this process?
the independent assortment of genetic material
the creation of an additional sex cell
continuity in the offspring cell's DNA
additional variation in the DNA of each sex cell formed
Crossing over is a mechanisms involved in introducing genetic variation. When the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed. Option D.
---------------------------------------
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
So, according to this information, when the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed.

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.
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.

Which best explains why all of the Earth’s freshwater is not available for human use?
Answer:
2.5% of the earth's fresh water is unavailable: locked up in glaciers, polar ice caps, atmosphere, and soil; highly polluted; or lies too far under the earth's surface to be extracted at an affordable cost.
Explanation:
99% of liquid freshwater on Earth is Stored as Ground water
Much of it probably isn't accessible to us Human.
About 71 % of Earth is covered in water, and the Ocean holds most of it but this is salt water, almost all fresh water is stored underground

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.
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.
how does carbon dioxide react with starch in plants?
Answer:
Higher concentrations of carbon dioxide make plants more productive because photosynthesis relies on using the sun's energy to synthesise sugar out of carbon dioxide and water. Plants and ecosystems use the sugar both as an energy source and as the basic building block for growth.

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.
