how do bacteria in hydrothermal vents produce food?
A. photosynthesis
B. chemosynthesis
C. osmoosis
D. by respiration

Answers

Answer 1
B... These microbes are the foundation for life in hydrothermal vent ecosystems. Instead of using light energy to turn carbon dioxide into sugar like plants do, they harvest chemical energy from the minerals and chemical compounds that spew from the vents—a process known as chemosynthesis .

A truck carrying fertilizer crashed near a stream within a few miles from this karst feature. The fertilizer spilled into the stream and was carried towards the sink hole. What effect will this have on the karst aquifer? Would you want to drink water from this aquifer?

Answers

Answer:

Eutrophication effect

Explanation:

The term eutrophication refers to the enrichment of surface water with nutrients. This process is related to human pollution activities.

Eutrophication is the biological process that generates in water by an oversupply of nutrients or organic matter. This matter, mainly compounded with nitrogen or phosphorous, favors the multiplication of phytoplankton (microscopic plants growing on the water surface) and other aquatic plants. This overgrowth leads to an enhance in primary productivity.

Little by little begin sedimentation, caused by the death of some vegetable organisms that sink in the bottom. These sediments rich in organic matter suffer decomposition in the presence of oxygen.

When oxygen disappears, anaerobic bacteria act and produce fermentation.

On the surface, plants and phytoplankton keep growing, creating a mantle that impedes the light to reach deeper areas. The overgrowth of phytoplankton on the water surface and the fermentation processes in the bottom originate toxic compounds that damage the animals. Animals die, creating more sediments in the bottom where there are anaerobic conditions. Decomposing processes and fermentation increases, producing a bad smell.

The result of eutrophication is the stratification of the water mass:

First superficial layer, the overgrowth of blue-green algae produce toxins and interrupt the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals.In the third layer, there is no oxygen, so life is not possible for animals or plants.In the fourth layer, there are animals and plants remains in the process of sedimentation.At the bottom, there is organic matter and anaerobic bacteria that are in charge of decomposition and fermentation, also producing toxic gases and smell.

mutation caused by the addition of a nucleotide to an already existing gene sequence called deletion duplication insertion inversion

Explanation:

Insertion is a type of mutation which adds nucleotide to an already existing gene sequence. It can lead to genetic disorders due to the change of gene sequence. An example of this genetic disorder is the trisomy 21 or commonly known as Down syndrome. Instead of having 46 cells, those people having this disorder have 47 cells because there is an extra copy of there gene 21.

What are some of the issues that come with catching shrimp in the wild? What are some of the problems associated with fish farms?

Answers

Answer:

Explanation:

There are many issues that can be thought of when it comes to both wild shrimp catching and fish farming. When catching wild shrimp, many fishers like to overfish. This can cause shrimp population levels to drop, and cause them to become endangered. There are also parasites, such as tapeworms in brine shrimp, which turn them bright red and make them very easy prey for bird species and such, and Orthione griffenis, better known as Griffen's isopod, which is a small isopod that attaches to a shrimp's gills and sucks the life out of them. Not only are these revolting, they're causing shrimp species to plummet.  

Fish farming is known of, and is a very profitable business. However, there are many concerns that can arise. One of these concerns is unethical treatment of the fish. Some farmers may starve or overfeed their fish, meanwhile others may overbreed them. There's also concerns of how the fish are acquired. If fish are taken from the wild to be farmed, some may see this as cruel or inhumane. Quality of life for the fish is a large concern, as if a fish is unhappy or ill, it can cause the consumer to fall ill from the product, which wound cause trouble for many.

There are many more issues that could arise, but overall, these are some of the most major issues when it comes to shrimp catching and fish farming.

Answer:

I think it’s active transport

The laboratory setup would most likely be used to demonstrate the process of diffusion.

What do you mean by Laboratory?

A Laboratory may be defined as a place where a variety of experiments may be performed depending on the work or projects it handles.

In this experiment, an artificial cell containing glucose and starch solution is dipped into the water containing a starch indicator.

The concentration of glucose or starch is found to be high in the artificial cell, hence, it removes the water or particles from the inside to the outside of the cell.

Diffusion may be defined as the movement of particles or matter from a region of high concentration to a region of low concentration.

Therefore, the laboratory setup would most likely be used to demonstrate the process of diffusion.

When fungi and bacteria decompose organic matter, they return ____ to the environment.

Answers

Answer:

Carbon and nitrogen.

probably

Hope that helped :)

Fungi and bacteria decompose organic matter, contributing to the formation of soil organic matter since they return nitrogen and carbon to the environment.

How is the decomposition of organic matter?

Fungi and bacteria break down residues and organic matter, excess nutrients (nitrogen, phosphorus and carbon) are released into the soil in forms that can be used by plants (nutrient availability).

The nitrogen released by these microorganisms is in the form of ammonium (NH4+) and thus readily available to the roots of plants and other organisms.

By decomposing residues and storing carbon within their own biomass, soil biota play a very important role in nutrient recycling processes.

Therefore, we can conclude that the most important function of fungi and bacteria microorganisms is the breakdown of organic materials.

Do convection currents of thermal energy form in Earth’s crust?

Answers

The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. Earth's solid crust acts as a heat insulator for the hot interior of the planet. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust. Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. Magma in the Earth's mantle moves in convection currents. The hot core heats the material above it, causing it to rise toward the crust, where it cools. The heat comes from the intense pressure on the rock, combined with the energy released from natural radioactive decay of elements. Description Magma or magma, meaning in Arabic, magma, magma, or magma, which is a mixture of fused silicon materials, or in other words with. Magma forms under the Earth's crust or other layers of the Earth.

Answers

Answer:

Pros of Biofuels

Renewable – Biofuels are produced from plants and other organic material, so it can be replenished constantly. This is in contrast to the fossil fuels, which are constantly in the process of being depleted.

Clean – Biofuels are environment-friendly. They are much efficient & cleaner than fossil fuels, producing less air pollution and using materials that would otherwise be considered as waste products. Biofuels cause much less greenhouse gas emissions in comparison to the conventional types of transport fuels.

Inexpensive – They can be made easily by using local materials. Biofuels are very cheap to afford. They are the cheapest types of fuels available in the world.

Flexible – can be easily mixed with other fuels.

Additives – Biofuels like ethanol and biodiesel are better for car engines than fossil fuels. Even if not being used as the main fuel source, they can be used as additives to improve performance.

Carbon neutral – the amount of carbon dioxide created by the burning of biofuels is equal to the CO2 absorption capacity of the plants. Hence, no extra CO2 remains in the atmosphere.
