Answer:
The solubilities in water of the three molecules from most to least soluble is in the following order: phosphate > deoxyribose > guanine.
Explanation:
The phosphate group is the most water-soluble due to it being very much negatively charged .
The deoxyribose which has several hydroxyl groups, is the next most water-soluble molecule.
The guanine molecule is hydrophobic, therefore, it is the least soluble in water.
A DNA molecule is composed of the three molecules: deoxyribose sugar, a phosphate group and a nitrogenous base which could either be a purine or a pyrimidine.
The three dimensional structure of DNA is such that the the phosphate groups and deodyribose sugars form the backbone of the structure on the outside of the DNA double helix where they are exposed to the aqueous environment of the nucleus. On the other hand, the hydrophobic nitrogeneous bases are located in the interior of the double helix where they are excluded from excludedthe aqueous environment of the nuclues. This structural arrangement is in accordance with the solubility of the molecules where the water-soluble phosphates and sugars are exposed to water while the water-insoluble bases are away from water.

Which situation is the best example of secondary succession?
A) An organism survives a difficult winter
B) The population in an area remains the same
C) One species replaces another species in an ecosystem after a forest fire
D) Each of several species uses the same amount of resources
Answers
Answer:
The answer is C
Explanation:
Secondary succession often occurs after a disaster, the ecosystem is not as primary as the primary succession, so it will take shorter time to recover. New species will occur in this place, and rebuild a constant environment. C is exactly the situation.
Hope this will help❤️
The best example of secondary succession is when one species replaces another species in an ecosystem after a forest fire. The correct option is C.
What is secondary succession?Secondary succession is a type of ecological succession that occurs on substrates that already have soil, and at least some organisms residing on it, like a forest or a community that has been disrupted by wildfire, tornadoes, or hurricanes.
The secondary succession in an ecosystem happens when a primary community is destroyed, for example, by wildfire. In secondary succession, the soil, seeds, and rhizomes survived in the soil and provides the foundation for the new community that is about to develop.
The rate of secondary succession varies according to the time taken for the primary community to regenerate, the level of disturbance of the habitat, the availability of propagules, and the dispersal capability of the species involved.
Therefore, the correct option is C.

What is the total amount of carbon removed from the atmosphere each year by the ocean and land plants, as shown by the arrows? (from carbon cycle gizmo)
Answers
Answer:
Either carbon got here by diffusing from the atmosphere, by decomposing marine life, or from circulating water from the deep ocean.
The ocean absorbs more carbon dioxide from the atmosphere than the land does.
The surface ocean takes in approximately 90 Gigatons of carbon per year.

Answers
Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.
What are seaweeds?
Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea.
Most are medium-sized, come in colors of red, green, brown, and black, and randomly wash up on beaches and shorelines just about everywhere.
The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold.
Therefore, Most living organisms need to take in oxygen to survive. It is responsible for plants and seaweed.

Where do majority of tornadoes occur in the United States?
Answers
Answer:

Explanation:
mainly in this area because of cold air coming in from canada and warmer air coming from the gulf of mexico meeting and causing tornados.
Answer:
A majority of tornadoes that occur in the United States, occur in the Midwest and Southeast region of the United States.
Explanation:
Tornadoes can impact just about every U.S. state, but the majority of these storms are concentrated in states throughout the Midwest and Southeast. In fact, of the average 1,137 tornadoes that occur in the United States each year, 64% of them form in states located in “Tornado Alley” and “Dixie Alley”, two regions with a disproportionately high frequency of tornadoes due to atmospheric conditions that persist for long stretches of the year.
With an average of 140 tornadoes annually, Texas is the most tornado-prone state in the U.S., followed by Kansas with 80 and Florida with 59, according to National Oceanic and Atmospheric Administration data.

What advantages does wifi applications of waves have over the previous technology?
Answers
Under the IEEE Wi-Fi standards, the available frequency bands are split into several separate channels. These channels overlap in frequency, and therefore Wi-Fi uses channels that are far apart. Within each of these channels, Wi-Fi uses a “spread spectrum” technique in which a signal is broken into pieces and transmitted over multiple frequencies. Spread spectrum enables the signal to be transmitted at a lower power per frequency and also allows multiple devices to use the same Wi-Fi transmitter. Because Wi-Fi signals are often transmitted over short distances (usually less than 100 metres [330 feet]) in indoor environments, the signal can reflect off walls, furniture, and other obstacles, thus arriving at multiple time intervals and causing a problem called multipath interference. Wi-Fi reduces multipath interference by combining three different ways of transmitting the signal (in a method developed by Australian engineer John O’Sullivan and collaborators). The popularity of Wi-Fi has grown steadily. Wi-Fi allows local area networks (LANs) to operate without cables and wiring, making it a popular choice for home and business networks. Wi-Fi can also be used to provide wireless broadband Internet access for many modern devices, such as laptops, smartphones, tablet computers, and electronic gaming consoles. Wi-Fi-enabled devices are able to connect to the Internet when they are near areas that have Wi-Fi access, called “hot spots.” Hot spots have become common, with many public places such as airports, hotels, bookstores, and coffee shops offering Wi-Fi access. Some cities have constructed free citywide Wi-Fi networks. A version of Wi-Fi called Wi-Fi Direct allows connectivity between devices without a LAN. Radiotelegraphy, radio communication by means of Morse Code or other coded signals. The radio carrier is modulated by changing its amplitude, frequency, or phase in accordance with the Morse dot-dash system or some other code. At the receiver the coded modulation is recovered by an appropriate demodulator and the code groups are converted into the corresponding symbols. In many instances the symbols are generated by a computer and modem rather than with a manual telegraph key.

The monomer units for constructing DNA and RNA are nucleotide bases, whereas amino acids, sugar residues, fatty acids, and acetyl groups are the monomers for proteins, carbohydrates, and lipids, respectively.Large polymers made of hundreds of monosaccharide monomers are known as polysaccharides, sometimes known as glycans. Polysaccharides, in contrast to mono- and disaccharides, are not sweet, and they typically are not soluble in water. The monomeric units of polysaccharides are joined by glycoside, linkages, just like disaccharides.What units are carbohydrates made up of?In the case of carbohydrates, the small repeating units are called monosaccharides.
