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.

Darwin's theory.
Explanation:
1. What else has to be
reproduced in a host cell to
produce a new virion?
Answer:
RNA viruses usually use the RNA core as a template for synthesis of viral genomic RNA and mRNA. The viral mRNA directs the host cell to synthesize viral enzymes and capsid proteins, and to assemble new virions.

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.

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.

Explanation:
The missing bases from this DNA molecule are filled as below:
GC, CG, TA, AT, TA, GC, CG, AT, CG, GC, TA, CG, GC, CG, and AT. What is a DNA molecule?A DNA molecule may be defined as a molecule that comprises the biological instructions that construct each species unique in terms of genetic sequences.
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.

Explanation:
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.

The property of water that explains the other properties listed below is hydrogen bonds.
WATER MOLECULES:Water is a unique molecule with unique properties that distinguishes it. Water is made up of two atoms of hydrogen and one atom of oxygen joined together by covalent bonds. Each water molecule is joined to one another by hydrogen bonds. These hydrogen bonds is responsible for the unique properties exhibited by water including adhesion & cohesion, solubility etc.Therefore, the property of water that explains the other properties listed below is hydrogen bonds.

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.

Identify ONE process that causes the metamorphism of an igneous rock into a metamorphic rock.
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.

1. Give an example of a behavior you observed in another person. When you looked at
their behavior, did you decide their action was more a result of circumstances, or their
personality? What information did you use to make your judgment? (6 points)
(its psychology btw)
Answer and Explanation:
The person to whom I observed a behavior that will be exposed in this response was a character from a show called "Reply 1988." This character showed a highly explosive behavior and was very nervous and stressed. I believe that this behavior is a result of the circumstances that this character was experiencing at the time, as he was under a state of great tension and stress, as he believed that his son had suffered a plane crash. In addition, this character has always shown a very calm and peaceful personality throughout his life, which shows that the explosive behavior was caused by the circumstances. To make this judgment I used the way the character behaves in his daily life and his interactions with other characters.
