Which of these statements is a scientific question that might be asked about
this food chain?
A. How would the populations of the fish change if shrimp started
eating fish?
B. Do mackerel eat more tuna or more shrimp in one day?
C. Where in the ocean do shrimp find the plankton that they eat?
D. How would a change in the population of shrimp affect the
populations of mackerel and tuna?
Answer:
A
Explanation:
A, because there's a food chain that's going to Plankton to shrimp and so on. That would be a scientific question they might ask about. It's also related to what the question is asking about and it's a more simple answer. I wouldn't think B or C is what they would ask about because it's not really related to the food chain. For D, it's a really good question. But, the food chain only shows a Plankton going to shrimp and so on. D is a bit more into deep thought and it doesn't really relate to the picture either.which of the following is an example of a stratovolcano

List the four spheres of the earth and describe three examples of processes that represent an exchange of
energy or matter between those spheres.
Answer:Four spheres of earth are:1)Lithosphere(land) 2)Hydrosphere(water) 3)Biosphere(living things) 4)Atmosphere(air).
Energy and matter flow through Earth's four spheres.Energy flows through the atmosphere and hydrosphere mostly by convection.The continuous cycling of matter and energy through earth's system makes life on earth possible .Others are driven by energy from the sun.
Explanation:
Four Spheres of the earth are lithosphere, hydrosphere, biosphere, and atmosphere. Three examples of processes that represent an exchange of energy or matter between those spheres. Evaporation ; the process by which liquid is converted to gas. Transpiration ; is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Convection ; a method of moving heat energy, found only in gases and liquids.
What affect interactions between the spheres?Human activities, such as the clearing of rain forests, pollution and changes in one component of one sphere can cause impacts that affect components of other spheres.
What is pollution?Pollution is the introduction of harmful materials into the environment. These harmful materials are called pollutants.
So these are the spheres of earth

defend Human Evolution against Scientific Creationism
Answer: According to the National Academy of Sciences (NAS), a scientific theory is “a well-substantiated explanation of some aspect of the natural world that can incorporate facts, laws, inferences, and tested hypotheses.” No amount of validation changes a theory into a law, which is a descriptive generalization about nature. So when scientists talk about the theory of evolution—or the atomic theory or the theory of relativity, for that matter—they are not expressing reservations about its truth.
Explanation: The theory of evolution, meaning the idea of descent with modification, one may also speak of the fact of evolution. The NAS defines a fact as “an observation that has been repeatedly confirmed and for all practical purposes is accepted as ‘true.’” The fossil record and abundant other evidence testify that organisms have evolved through time. Although no one observed those transformations, the indirect evidence is clear, unambiguous and compelling.

GRADPOINT Which of the following foods would have the LEAST greenhouse gas footprint?A fish B beef C vegetables D nuts
Answer:Fish.
In most cases the differences observed by the impacts of methane on the climate is called the greenhouse footprint.Beef and lamb, has higher green house effect than pork, chicken and vegetables.
.
Beef and lamb systems emissions are dominated by methane.This is a short lived gas that has potent effects on global warming.Thus these animals have higher foot prints.
Besides, the destruction of plants population during grazing and rearing disrupts the CO2 cycle which may lead to the green house effect.
However, fishery does not need destruction of vegetation for farmland for rearing,and compare to above. Neither is methane released from the emission.They therefore have less less footprint.
Fish has lower green house effect,It is therefore the least

8. Complete the chart by describing what kinds of organs or tissues each type of
germ layer becomes:
Endoderm...
Mesoderm becomes...
Ectoderm becomes...
The endoderm forms organs of the digestive and respiratory systems, the mesoderm gives rise to structures of the musculoskeletal and circulatory systems, and the ectoderm develops the nervous system and outer coverings of the body.
The three germ layers - endoderm, mesoderm, and ectoderm - are the primary cell layers that form during embryonic development. Each germ layer gives rise to specific organs and tissues in the body.
1. Endoderm: The endoderm is the innermost germ layer and gives rise to various organs of the digestive and respiratory systems. It forms the lining of the gastrointestinal tract, including the stomach, intestines, and liver. Additionally, the endoderm gives rise to the lungs, pancreas, and thyroid gland.
2. Mesoderm: The mesoderm is the middle germ layer and develops into several structures, including the musculoskeletal system, circulatory system, and urinary system. It gives rise to the muscles, bones, cartilage, and connective tissues of the body. The mesoderm also forms the heart, blood vessels, kidneys, and reproductive organs.
3. Ectoderm: The ectoderm is the outermost germ layer and gives rise to the nervous system, as well as the epidermis (outer layer of the skin). It develops into the brain, spinal cord, and peripheral nerves. The ectoderm also forms the sensory organs such as the eyes, ears, and nose. Additionally, it gives rise to hair, nails, and certain glands like the sweat glands.
In summary, the endoderm forms organs of the digestive and respiratory systems, the mesoderm gives rise to structures of the musculoskeletal and circulatory systems, and the ectoderm develops the nervous system and outer coverings of the body.

2 predators increase because many fishes eat each other bcz of competition
3 so relating point 2 competition also increase
The fish developed the gills because of genetic modification . Because the fish are now able to swim in deep water, their predators in shallower water will have less food. Likewise, competition for food among deep-water fish that eat the same types of food will increase.
What are the adaptations of fish gills?Gills are organs that filter oxygen from the surrounding water. The inside structure of gills is an adaptation that enables two processes to occur: acquiring oxygen and removing a waste product called carbon dioxide.
Fish are able to efficiently exchange gases thanks to the vast surface area of their gills, which allows for this process. The extensive amount of surface area that the blood capillaries in each gill filament contribute because of the little distance that must be traveled for diffusion, both the outer layer of the gill filaments and the walls of the capillaries are only one cell thick.

Which statement best describes how a catalyst can speed up a chemical reaction? The catalyst decreases the reaction energy needed. The catalyst increases the concentration of products. The catalyst binds to enzymes to release substrates. The catalyst increases the concentration of reactants.
Answer:
The catalyst decreases the reaction energy needed.
Explanation:
The catalyst speeds up chemical reactions by decreasing the amount of activation energy/reaction energy needed in the reaction.
Compared to reactions without catalysts, they are much faster because there is less activation energy needed.
Catalyst is any substance that causes or increases the rate of a chemical reaction without itself being consumed For example - enzymes are biocatalysts.
The catalyst can speed up a chemical reaction by reducing the activation energy or by changing the reaction mechanism.
The minimum amount of extra energy required by a reacting molecule to get converted into the product is defined as activation energy.
So, the correct answer is The catalyst decreases the reaction energy needed.
Other options-
The catalyst increases the concentration of products- incorrect. Catalysts do not affect the equilibrium concentrations of products or reactants. The catalyst binds to enzymes to release substrates- incorrect. The catalyst binds to the substrate and converts the substrate into products.The catalyst increases the concentration of reactants- incorrect.

Drag the tiles to the correct boxes to complete the pairs. Match each biodiversity restoration method to its description.Select the correct answer. Which statement is true about biodiversity?
Answer:
*Using plants to control a native plant population - Reforestation
*Using plants to absorb harmful compounds - Bioremediation
*Using plants to increase biodiversity and food resources - Biological Augmentation
Explanation:
Reforestation is an act of restoring biodiversity back in an area by planting native trees that once populated the area, but due to deforestation, and other factors, the species became depleted. Bioremediation is a form of biodiversity restoration method which involves Phytoremediation. This process involves the use of plants which absorbs harmful substances such as petroleum products by binding to them and extracting them.Biological Augmentation is a process of introducing cultured bacteria, such as archaea, into contaminated soils in order to increase the rate of the break down of those substances in the soil. This in turn improves the soil biodiversity and also food resources.Watch this video that shows the leaves of a Mimosa pudica plant. What characteristic of life does the video show?
