what statement describes the danger of using heavy metals to control microbe growth?

A.heavy metals promote biofilm formation in humans

B.heavy metals stimulate some microbes to reproduce even more

C.heavy metals are toxic to many organisms besides microbes

D.heavy metals can assist with virus attachment to host cells

Answers

Answer 1

Answer:

The correct answer is - option C.

Explanation:

Heavy metals can alter the physiological and biochemical qualities or nature of the microbes or microorganisms. For instance, Chromium is able to denature the proteins of microbes and may cause oxidative damage.

Using heavy metals to control the microbe growth can be very dangerous as the ions of these heavy metals bind themselves to amino acid containing sulfur tightly and accumulate in the cells. This can be very toxic the most of the organisms besides the microbes.

Thus, the correct answer is - option C

Answer to 1: a black hole is a tremendous amount of matter crammed into a very small (zero) amount of space. Answer to 2: the top of your head would feel so much more gravitational pull than the tips of your toes that you would be stretched, longer and longer Answer to 3: A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying. because no light can get out, people can't see black holes Answer to 4: stellar, intermediate, supermassive, and miniature. Answer to 5: the asymmetry of bright and dark sections of the ring are caused by the Doppler effect as the matter is coming toward Earth (brighter) or receding (dimmer).

The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label A? an arrow pointing from A to a formation of trenches and Island Arcs, an arrow pointing from B and C to an Oceanic Spreading Ridge, and an arrow pointing from D to a trench. © 2016 US Department of the Interior; US Geological Survey Divergent boundary zones Convergent boundary zones Plate boundary zones Transform boundary zones

Answers

Answer:

The label A corresponds to Convergent boundary zones  

Explanation:  

When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped volcanic islands, the island arches. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.

Convergent boundaries

B. Littoral, profundal, limnetic
C. Limnetic, littoral, profundal
D. Littoral, limnetic, profundal

Answers

Answer:

D. Littoral, limnetic, profundal

Explanation:

The level of water bodies like ponds and lakes are divided into different zones from top to bottom and side to side. The Littoral zone starts from the dry land that moves in a downward direction towards the open water. There are lots of nutrients and minerals in this zone. Insects, small fish, and zooplankton live in this zone. The limnetic zone starts after the littoral zone ends. It is the part of the pond which receives the sunlight. Algae and other plants live in this zone because the level of oxygen is high in this area. The profundal zone is located where the sunlight does not reach. The population of fish is very low in this zone.

What is independent variable?

The indepent variable is something that is stable , it does not change & the dependent variable is that variable that depends on the independent variable.

The experimenter's chosen variable or variables are considered independent. The anticipated "cause" will be this manipulation. The independent variable's value determines how much the dependent variable is worth.

The result of the cause will be this (if the manipulation succeeds). One group of volunteers receives a medication, while the other receives a placebo. Cancers diminish in the medication group but they do not in the control (placebo) group.

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.

Answers

the anwser is a caves and sink holes

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.
