Which features are usually associated with karst topography?
A. Caves and sinkholes
B. Lakes and wetlands
C. Mountains and valleys
D. Plains and plateaus
Answers
A. Caves and sinkholes are usually associated with karst topography.
How Karst topography is formed?Karst topography is formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. As water flows through these rocks, it dissolves them, creating underground cavities and channels.
Over time, the ground above these cavities can sink, forming sinkholes. The dissolved rock can also create caves and other unique features such as natural bridges, disappearing streams, and springs.
Karst topography is a type of landscape that is characterized by distinctive landforms and features that are formed by the dissolution of soluble rocks, such as limestone, dolomite, and gypsum.
These rocks are highly susceptible to chemical weathering, which is the breakdown of rocks and minerals through chemical reactions. The process of chemical weathering dissolves the rocks, leaving behind distinctive landforms and features.
Overall, karst topography is a unique and fascinating landscape that is created by the dissolution of soluble rocks. The distinctive features of karst topography, including caves, sinkholes, natural bridges, disappearing streams, and springs, make it a popular area for exploration and study.
However, the hazards associated with sinkholes and other features of karst topography also make it important to be aware of the risks when living or traveling in these areas.

8. Complete the chart by describing what kinds of organs or tissues each type of
germ layer becomes:
Endoderm...
Mesoderm becomes...
Ectoderm becomes...
Answers
Endoderm becomes: The endoderm produced during gastrulation will form the lining of the digestive tract, as well as that of the lungs and thyroid.
Ectoderm becomes: After gastrulation, the embryo goes through a process called neurulation, which starts the development of nervous system. During neurulation, ectoderm differentiates into two parts. The first is the surface ectoderm, which gives rise to tissues on the outer surface of the body like epidermis, hair, and nails.
HOPE THIS HELPS!!!!!!!!
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.

defend Human Evolution against Scientific Creationism
Answers
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.

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?
Answers
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.A species of fish evolved over thousands of years to have gills that allowed the fish to swim deep in the sea.

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.

C. Where in the ocean do shrimp find the plankton that they eat?

Answers
Answer:

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.
