Answer:
Sharks keep ocean ecosystems in balance
Sharks limit the abundance of their prey, which then affects the prey of those animals, and so on throughout the food web. Because sharks directly or indirectly affect all levels of the food web, they help to maintain structure in healthy ocean ecosystems. HOPE THIS HELPS!!!!!!!!
Explanation:
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.

*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.

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.

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.
Explanation:
Without water they cant do any of this.
Answer:
Cells will lose water and the chemical reactions take place in water. Without enough water, this can't happen.Explanation:
Which step occurs in meiosis to prepare for fertilization in sexually
reproducing organisms?
Answer: 12 sexual reproduction and meiosis concept outline
Explanation: The process of meiosis produces unique reproductive cells called gametes, which have half the number of chromosomes as the parent cell. Fertilization, the fusion of haploid gametes from two individuals, restores the diploid condition. Thus, sexually-reproducing organisms alternate between haploid and diploid stages.

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.
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.

1. What do you know about gravity?
2. How could gravity affect the water cycle?
Explain your answer.''
Explanation:
What do you know about gravity?
ans:Gravity is a force of attraction that exists between any two masses, any two bodies, any two particles. Gravity is not just the attraction between objects and the Earth. It is an attraction that exists between all objects, everywhere in the universe. ... where G is called the Gravitational Constant.
How could gravity affect the water cycle?
ans:It pulls precipitation down from clouds and pulls water downhill. Gravity also moves air and ocean water. ... Gravity pulls denser air and water downward, forcing less dense air and water to move upward. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

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.
