Draw the structures of deoxyribose, guanine, and phosphate and rate their relative solubilities in water (most soluble to least soluble). How are these solubilities consistent with the three-dimensional structure of double-stranded DNA?
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.

Karyotype
Karyotype refers to the number and appearance of chromosomes present within the nucleus of a eukaryotic cell. It is illustrated as a diagram such as given in the question.
There is no Down's syndrome as the karyotype demonstrates a normal pair of chromosome 21. In this karyotype, there is an extra X-chromosome that depicts non-disjunction during either oogenesis or spermatogenesis (gamete formation) in the parents leading to the 23rd trisomy.

How does the photolysis of water benefit the biosphere?
why groups of animals are found on some islands but not others?
Answer:
Wilson has created the theory of the biogeographic nature of the island, which predicts that the number of species on the island depends on the balance between colonization, the evolution of the novel island species, and extinction.
Explanation:
A new DNA sequence containing 596 species of terrestrial birds from 41 island chains (archipelagos) around the world has been assembled by the researchers. The data combined sample data from their own field visits, research, and field samples from GeneBank colleagues. This information was utilized to build and employ a dynamic model that predicted international relationships that regulate biodiversity variation in their novel analysis approaches. In that, they confirmed two main components of MacArthur and Wilson's initial biogeography theory on the island.
The understanding of biodiversity on the island is important to conservation but also has implications beyond that – when imposing barriers to species dispersal it could enable us to assess better the effects of human activities, and it can contribute to a wider understanding of biodiversity around the globe.

iii. Describe the contributions of photosynthesis and cellular respiration within and among
the four spheres. Discuss how carbon enters and leaves each of the four spheres and in

Discuss the role of carbon storage in organisms
It only has to be one paragraph :)
Answer:
Plants reform the carbon into climatic carbon dioxide into carbon-containing organic compounds, such as sugars, fats, and proteins. Plants take in carbon dioxide by minute openings into their leaves, called stomata. They connect atmospheric carbon with water and produce organic compounds, utilizing energy trapped from sunlight in a method called photosynthesis. The by-product of photosynthesis is oxygen, which plants discharge into the atmosphere by the stomata.

How do divisions in the geologic time scale differ from the way we organize time using a clock?
Explanation:
The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.
The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.
Geologic timescalePlanet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:
EonsErasPeriodsEpochsand ages.Eons are large and indeterminate spans of time and are divided into four classifications:
Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.
To get a rough idea of how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.
Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.

Answer:

Hope this helps!
Measure the volume of a balloon filled with room temperature air; place the balloon in a freezer for an hour and measure its volume again would best investigate the effect temperature has on the volume of a gas. So, the correct option is C.
How volume effect the temperature of the gas?The ideal gas law states that the temperature of a gas is directly proportional to its volume. Specifically, the temperature of a gas will increase if its volume is decreased while its volume and pressure remain unchanged. If the volume of a gas is increased, its temperature will fall but its volume and pressure will remain unchanged.
This relationship can be explained by the fact that when a gas is compressed (that is, its volume decreases), the molecules are confined to a smaller area and move more away from each other and the walls of the container. Bars collide. Due to the increasing frequency of impacts, there is also an increase in kinetic energy, which increases the temperature.
So, the correct option is C.

Explanation:Durante la respiración celular, una molécula de glucosa se degrada poco a poco en dióxido de carbono y agua. Al mismo tiempo, se produce directamente un poco de ATP en las reacciones que transforman a la glucosa. No obstante, más tarde se produce mucho más ATP en un proceso llamado fosforilación oxidativa.Las células procariotas llevan a cabo la respiración celular dentro del citoplasma o en las superficies internas de las células. Aquí se hará mayor hincapié en las células eucariotas, en donde las mitocondrias, son el lugar donde se produce la mayoría de las reacciones.
Se produce en la mitocondria. La respiración celular, como componente del metabolismo, es un proceso catabólico, en el cual la energía contenida en los sustratos usados como combustible es liberada de manera controlada.

When energy is transferred to or from a substance, it can change the molecules’ freedom of movement. True or False?
Answer:
True
Explanation:
When transfer energy, the substance's temperature changes which can change the molecules' freedom. For example, when water freezes the water molecules loose temperature and slow down, unlike in a gas where molecules are free and energetic.
