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.
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.

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.
A dry cement road is a diffuse reflector. When it rains, the water fills in all the little holes and cracks in the cement road and it becomes a smooth regular reflector. At night, when you are depending on the light from your headlights to show you the lines on the road, a wet road becomes much darker and it is more difficult to see the lines. Explain why this occurs.
Answer:
Because of reflection of light away from the marking
Explanation:
It is because the light from a vehicle falls on the road and its markings which then gets illuminated as light is reflected only in one direction.
But in case when the road is wet, light of vehicle reflects in different directions away from the markings on the road and hence they do not illuminate.
The reason why the given phenomenon about the effect of light and while driving is; Due to total internal reflection of light away from the marking.
What is reflection of light?Reflection of light is simply defined as the phenomenon where light is sent back after being incident on a surface.
Now, in this question, the light from a vehicle falls on the road and its markings and then gets illuminated as light is reflected only in one direction.
However, when the road is wet, the headlight of vehicles tend to reflect away from the markings on the road in different directions which make them not to illuminate.
Thus, we conclude that reason why the given phenomenon about the effect of light and water on driving is due to total internal reflection of light away from the marking.

What causes weather fronts to move?
Answer:
A warm air mass pushes into a colder air mass (the warm front), and then another cold air mass pushes into the warm air mass (the cold front). Because cold fronts move faster, the cold front is likely to overtake the warm front. ... The warm air rises as these air masses come together.
Explanation:

Answer:
when warm air rises cold air covers the spot it was in so its a cycle warm air rises cold air fills its place
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
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.

Explain what is diffusion and osmosis? Why are they Important to the cell? Explain one example of active transport in the cell. Write a paragraph (5-7 sentences).
-if you help I really appreciate you!
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.

Which statement provides the best argument against making major changes to the atmosphere to help protect Earth’s resources? There will be less soil and dust in the air as construction increases. The atmosphere will improve as more people move to large cities. Making major changes to the atmosphere can be a costly process. It is more important to protect land and water resources than the atmosphere.
The answer is C. Making major changes to the atmosphere can be a costly process
Explanation:
Making major changes to the atmosphere can be a costly process.
The atmosphere refers to the layer of thin gases that lie above the surface of the earth. Plants and animals depend on the atmosphere for survival because it is region in which gaseous exchange takes place.
Changes to the atmosphere is very costly because it involves changes such as alteration in the kind of cars that are used and devising of alternative sources of energy etc. All these are expensive adventures.

Which of the following information would be most useful in determining whether 2 species are closely related?
A) There leg bones look very similar
B) The age of their bones, determined by carbon dating, is the same
C) The dna sequence found in their bones varies by only a few genes
D) The bones were found in the same layer rock
The most helpful way to determine whether two species are closely related is by comparing the appearance of their leg bones which is called as the Analogous structure. So, the correct option is A.
What is an Analogous structure?In contrast to homologous structures, analogous structures are characteristics of different species that have evolved in response to a similar environmental challenge and are similar but not necessarily in structure.
Example of Analogous structures are an insect's wings and a bird's wings are similar in structure. Although each of these species utilize their wings to fly, the origins of their wings are different.
For the aforementioned example, examining the appearance of two species' leg bones will most accurately reveal whether two species are closely related.
Therefore, the correct option is A.

Mitosis consists of four basic phases: Prophase, Metaphase, Anaphase, and Telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.
A. Prophase
Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.B. Metaphase
Metaphase is the third phase of mitosis, the process that separates duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.C. Anaphase
Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.D. Telophase
Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.The third stage of mitosis, known as metaphase, is when the genetic material that was replicated and carried in the parent cell's nucleus is split into two identical daughter cells.
What are the different phases of mitosis?There are four fundamental stages of mitosis: prophase, metaphase, anaphase, and telophase.
Cytokinesis, which is the process of separating a cell's contents into two new cells, begins in either anaphase or telophase, where the phases are strictly sequentially ordered.
The division of the duplicated genetic material contained in a parent cell's nucleus into two identical daughter cells is called mitosis, and the process begins with the prophase.
