Artesian springs bring pressurized groundwater to the surface through which feature of Karst topography?
streams
caves
fissures
igneous rock
Answer:
The correct answer is D) Fissures
Explanation:
Karst is a topography or landform that is created by the dissolution of soluble rocks beneath the surface by waters from the surface or below.
Fissures are formed when because of earth movements there is the occurrence of a long, narrow opening, in the earth.
Artesian springs refer to the water coming out through these cracks or openings in the earth onto the surface of the Karst topography.

Some human white blood cells help destroy pathogenic bacteria by *
(1) causing mutations in the bacteria
(2) engulfing and digesting the bacteria
(3) producing toxins that compete with bacterial toxins
O (4) inserting part of their DNA into the bacterial cells
Answer:
2
Explanation:
They either engulfy and digest pathogens(phagocytosis) or produces antibodies.
Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.
Thus, By engulfing pathogenic bacteria through a process known as phagocytosis, some human white blood cells, notably phagocytes like neutrophils and macrophages, aid in the destruction of pathogenic germs.
These phagocytes have the capacity to identify and bind to bacteria, creating a phagosome—a membrane-bound compartment—around the bacterium.
The phagosome then joins forces with lysosomes, which are organelles that carry digesting enzymes, to create a phagolysosome. The bacteria are exposed to the lysosomal enzymes inside the phagolysosome, which causes them to break down and die.
Thus, Some human white blood cells help destroy pathogenic bacteria by engulfing and digesting the bacteria. The correct option is B.

Capillaries are very thin, narrow blood vessels that allow for the transfer of oxygen, carbon dioxide, and nutrients. The image shows
how normal red blood cells and sickle-shaped red blood cells flow through a capillary,
Use information in the image to describe two ways that the sickle cell gene mutation affects the ability of red blood cells to perform
their normal function
Answer:
less packaging of oxygen
Explanation:
normal RBC (red blood cells) have a large surface area for oxygen packaging due to its biconcave shape but when mutation occurs the RBC being produced by the short bones is sickle shaped reducing surface area of haemoglobin exposed, responsible for packaging oxygen so tissues don't get right amount of oxygen

Which is a plausible solution to human activities contributing to increasing amounts of carbon dioxide in the atmosphere?
А
Use only alternative energies for the production of electricity
B
Require all new automobiles manufactured to run on electricity rather than gasoline.
с
Plant more trees and decrease deforestation practices so that more carbon dioxide can be absorbed from the atmosphere.
D
Require everybody to use mass transportation or methods of transportation that do not require burning fossil fuels, such as riding bicycles,
©2021 Illuminate Education Inc.
Answer:
hmm
Explanation:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Plausible solution to human activities contributing to increasing amounts of carbon dioxide(carbon emission) in the atmosphere are :
Use only alternative energies for the production of electricityCarbon emission (greenhouse gas emissions) from human activities strengthen the greenhouse effect, causing climate change. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution.
Alternative energy is energy that is collected from renewable resources that are naturally replenished on a human timescale, hence contributing to betterment of environment.To know more about carbon emission here

What do coral reefs and estuaries have in common?
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

Explanation: all other traits are irrelevant and could reply to any part o the food chain, c means that the plats have dropped, meaning that the things that eat the plants wot be able to eat the plants, (primary consumers)and the secondary consumers wont be able to eat the primary consumers,then the tertiary consumers wont be able to eat the secondary consumers. In simpler terms it would cause a chain reaction that would detonate the whole foodchain.
