Why are proteins so important?
Answer:
Humans can't survive without all nine essential amino acids. Protein is essential to building bones,and body tissues, such as muscles, but protein does much more than that. Protein participates in practically every process of a cell.
Why does the starch remain present and is detected by iodine in the boiled solution?
Answer:
Amylose in starch is responsible for the formation of a deep blue color in the presence of iodine. The iodine molecule slips inside of the amylose coil. ... A blue-black color results if starch is present. If starch amylose is not present, then the color will stay orange or yellow. I hope this helps!

Which 2 events during meiosis increase GENETIC
VARIATION by ensuring that each egg and each
sperm will be unique?
Answer:
(three) crossing over, mutations caused during crossing over, and independent assortment.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.

How do moving glaciers change the surface of the earth??? please help!!!
Answer:
Glaciers are massive bodies of ice that move across the surface of the Earth like rivers. As glaciers move they change the surface of the Earth by wearing away loose rocks and soil and depositing them somewhere else.
Explanation:
Answer:
Glaciers change the surface of the earth by causing small or large amounts of material to be pushed out of the way as the glacier slides along a path set by gravity and angle of the slope it is on.

Some cnidarians are unique in exhibiting polyp and medusa forms. How might their two body forms give them an advantage over species that have only one body form?
Answer:
Explanation:
cnidarians are mostly marine animals. they exibit alternation of generation with two different body forms. their larval stage is polyp and the maturation stage is madusa. these two different forms help them to survive. polyp stage is sessile while medusa stage is free swiming. they can get food migrate and do sexual reproduction. their are also some cniderians that exhibit only one body form. these are less suited to environment as compared to the others that haae two body forms.
Often During summer months large bodies of water will experience "fish kill." These do not happen during the winter months. Explain these events using your understand of the properties of water.
Answer: see below.
Explanation:
gases dissolve more in colder water, so in summer the water can become oxygen depleted. Evaporation in summer can reduce water volume; even in summer rainfall climate evaporation rates may exceed precipitation. Evaporation will also cause higher conentrations of solutes of which some may reach toxic levels. Summer sun may also cause algal or cyanobacterial blooms which can further deplete dissolved oxygen and may release toxins into the water.

What part of meiosis is responsible for variation?
Answer:
the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Answer:
The two events that set meiosis apart from mitosis are known as crossing over (or genetic recombination) and independent assortment. These occur in prophase and metaphase of meiosis
During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Explanation:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I

Why do individuals with low
levels of fitness die?
How do adaptations help an organism as they struggle for existence?
Answer:
low level of fitness means the individuals have little or no adaptations.
while adaptations are those changes that help an organism to struggle and survive. it increases the survival rate of an organism. adaptations are the changes in DNA in the form of mutations and recombinations. it increase immunity of an organism and improve its fitness.
Explanation:
which statement describes the law of superposition
A. Sedimentary rocks were originally in horizontal layers
B. In horizontal rock layers, each layer is younger than the one below it
C. Rock layers must be in existence before something can happen to them
D. Rocks that are not in horizontal layers were shifted by some geologic event.
Answer:
B. In horizontal rock layers, each layer is younger than the one below it
Explanation:
Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence. ... It is one of the great general principles of geology..
Why do we use different radioactive isotopes to determine timescale?
We use different radioactive isotopes to determine timescale because decay within the rocks according to their half-life rates, and by selecting the appropriate minerals and measuring the relative amounts of parent and daughter isotopes in them, the date at which the rock crystallized can be determined.

1.what effect does air pressure have on wind movement?
2.what happens to the density of air as it is heated
3. It’s a hot, sunny morning in a coastal town in south Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer: 1) Gases move from high-pressure areas to low-pressure areas. And the bigger the difference between the pressures, the faster the air will move from the high to the low pressure. That rush of air is the wind we experience. 2) So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons.
Explanation: 3) Now that there are large puffy clouds in the area, most of sunlight will be clocked from reaching the earth's surface. The land will cool faster than the ocean (because water has a high heat capacity and has to lose more energy to drop by a degree which will take longer than land).
Explanation:
1)Air pressure drives the creation of wind worldwide. Although it is not the only factor, differences in air pressure throughout the Earth's atmosphere lead directly to wind and influence the speed and direction of that wind. Pressure differences also affect larger weather systems like storms, even hurricanes.
2)
Heating of the earth, which in turn heats the atmosphere, is responsible for the motions and movements of the air in the atmosphere. The faster molecules move, the hotter the air. As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward. This is the concept used in the hot air balloons. The air is heated by the burner and the expanding air becomes less dense, causing the balloon to rise through the denser, cooler surrounding air.
