Answer:
Diffusion and osmosis are both passive transport processes that act to equalize the concentration of a solution. In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. Significance of Diffusion and Osmosis Both diffusion and osmosis are really important as these ensure the equalization of forces inside cells and also inside an organism as a whole by spreading all the necessary chemicals and nutrients from highly concentrated area to the low concentration area inside an organism. The intake of water in plants is an example of osmosis. Diffusion is observed when a drop of food coloring is added to a glass of water, where eventually, the entire water content becomes colored.

5. Consider a system consisting of an egg in an incubator. The white and yolk of the egg contain proteins, carbohydrates, and lipids. If fertilized, the egg is transformed from a single cell to a complex organism. Discuss this irreversible process in terms of the entropy changes in the system, surroundings, and universe. Be sure that you first clearly define the system and surroundings.
Answer:
According to the question, we could consider the developing chick as the system and the surrounding of this system would be nutrients, external environment, or world and eggshell that affects the system. The entropy of the system decreases with the transformation of the development of the cell into a chick drastically.
In this system initially, it has a low entropy condition as it the surrounding have complex fuel molecule compare to the system, however, during the period of incubation the complex molecule of surrounding fuel release in the high quantity of CO2 and water molecules and leads to the higher entropy of surrounding than the decrease in the entropy of the system.
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.
Based on the data, which of the following most accurately matches a potential change with its predicted effects on the southern Florida ecosystem?
A) Introduction of a new top predator species that preys solely on Burmese pythons would cause an increase in
the raccoon population.
B) If the population of Burmese pythons were to decrease, then the cotton rat population would increase.
С) If more Burmese pythons are introduced in the Everglades, then mosquitoes will begin feeding on white-tailed deer frequently again.
D) Introduction of a new snake species that competes with the Burmese python for food would lead to an
increase in the white-tailed deer population.
Answer: A

*Earth Science* Active continental margins where the plate boundary is ocean-continent convergent are characterized by accretionary wedges.
True or false?
The correct answer is True
Explanation
An accretion wedge is an area where deformed sediment accumulates that occurs at a convergent edge at the boundaries of subduction plates (ocean-continent). This process occurs when sediments from the oceanic crust accumulate to the block of continental crust produced. by the subduction movement of the oceanic crust. So, the correct answer is True.

Does nutrients cycle within and between ecosystems?
Which natural resource is renewable?
A. coal
B. wind
C. topsoil
D. oil
Wind is the natural resource which is renewable. Therefore, option (B) is correct.
Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.
Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.

Which phrase is associated with asexual reproduction but not sexual
reproduction?
Answer: B. Genetically identical offspring
Explanation:
Asexual reproduction that means the parent organism will split into two organisms, and that there will be no mixing of the DNA, as it is the case in case of the sexual reproduction which mixes up the DNA. Therefore the child and the parent organism will contain exactly the same genetic material.
Why do organisms die if they do not have enough water?
Answer:
Organisms need water for the following activities: (1) All cellular processes occur due to water. (2) Transportation of substances in our body takes place by dissolving in water. (3) Terrestrial animals require fresh water for transportation of minerals and for getting rid of waste from their body.

Relate plant structure and function to the process of photosynthesis and respiration
Answer: Photosynthesis is a process through which green plants prepare their food by using carbon dioxide and water as reactants in the presence of sunlight energy. The food produced in the form of carbohydrate. Respiration is the process in which the biochemical oxidation of the food occurs.
Explanation:
The plant structures like leaves are specialized for performing the process of photosynthesis. These leaves have chlorophyll pigment which traps the light energy from sun which is required for splitting the molecules of water in the process of photosynthesis. Respiration occurs through stomata in leaves. But it also occurs in stems through lenticels and in specialized roots called pneumatophores via tiny pores.
