How do sinkholes form? Be sure to provide a detailed explanation of sinkhole formation.
Answer:
See below
Explanation:
Over hundreds of thousands of years, layers of rocks like bedrock and limestone erode. Then, a hole or cavity forms when it erodes. Slowly, the matter above the cavity falls in. This causes it to expand. Drought is also another reason that sinkholes form in the ground.
Answer:
Sample Answer edge 2021
Explanation:
When it rains, rainwater, which is slightly acidic, soaks into the ground and becomes more acidic as it moves through the soil. When this water comes in contact with the bedrock, it reacts with the limestone, dissolving it. As the water flows through the ground, it carries the dissolved limestone away with it, enlarging the natural holes and cracks that were already present in the rock. Over time, large cavities may form in the bedrock. Sinkholes often form when the overlying sediments become too heavy for the ceiling of an underground cavity to support. The ceiling gives way and the overlying sediments collapse into the cavity.
A solid reactant is placed into a beaker of a warm water. The liquid vigorously bubbles as the solid dissolves into the solution. What will most likely happen if the temperature of the liquid is slightly reduced?
More bubbles will be produced because the solution is becoming more concentrated.
Fewer bubbles will be produced because of fewer collisions of reactant molecules.
The solid will get smaller at a faster rate because of more collisions of reactant molecules.
The solid will get larger at a slower rate because precipitate is coming out of the solution.
Answer: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
Answer:
B: Fewer bubbles will be produced because of fewer collisions of reactant molecules.

Explanation:
Lactase is an enzyme that is produced in the lining of the intestines. This enzyme helps the body speed up the
breakdown of carbohydrates that are found in dairy products, such as milk, yogurt, and cheese.
Which general function does lactase perform?
Answer:
Regulation of cell processes
Explanation:
Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.
How will you isolate DNA from a pure fungal culture
Answer:
Explanation:
There are several ways of isolating DNA from a pure fungal culture but you can use the CTAB method.
In this method, genomic DNA can be extracted.
First of all, the cell walls of fungal mycelia can first be broken down by grinding it using glass rods or you can use or liquid nitrogen. Place it in a plate. You can now CTAB extraction buffer , then incubate at 65°C, then let it undergo purification with phenol:chloroform:isoamyl alcohol 25: 24: 1 and carry out precipitation with isopropanol . Then the DNA can be extracted and then dissolved in 50 μl of pure water.
The skin is protected by the action of cells that arise from bone marrow and migrate to the epidermis. Which cells serve this function?
Answer:
Langerhan's cells
Explanation:
The Langerhan's cells arise from the bone marrow and migrate to the epidermis. The Langerhan's cells are the body's first line of defense and play a significant role in antigen presentation. They need special stains to be visualized and are primarily found in the stratum spinosum. These are the mesenchymal origin obtained from CD34 positive stem cells of bone marrow and are part of the mononuclear phagocytic system.
Which of the following explains why the Midwest is not suffering as severe damage from acid rain as are the northeastern states?
a. Midwest has few sources of acid rain-forming pollutants.
b. pH of rainfall in Midwest is significantly higher than that in the Northeast.
c. soils in the Midwest have a higher buffering capacity than do those in the Northeast.
d. soils in the Midwest have a lower buffering capacity than do those in the Northeast.
e. Midwestern soils have lower concentrations of toxic metals to be leached into watersheds.
Answer:
a. Midwest has few sources of acid rain-forming pollutants.
Explanation:
Midwest has few sources of acid rain-forming pollutants because Midwest has less number of factories which produces less pollution. Farming, mining, and manufacturing of different products are the major industries Midwest. Other industries like transportation, finance, and machinery are also important for the economy of Midwest. Due to less number of factories less amount of pollutants goes to the atmosphere and will not cause acid rain.

(f) Microfilaments, intermediate filaments, microtubules
(g) Microfilaments, microtubules
(h) Microfilaments, intermediate filaments, microtubules
(i) Microtubules, microfilaments
(j) Microtubules
Explanation:
Microtubules (MTs) are dimers of the protein tubulin (alpha- and beta-tubulin subunits) and they are major components of the cytoskeleton. MTs play diverse cellular roles including, mechanical support (cytoskeleton), transport, motility, chromosome segregation, etc. Microfilaments (MFs) are protein filaments that also form part of the cytoskeleton in eukaryotic cells. MFs consist of G-actin monomers assembled in linear actin polymers, and their functions include mechanical support, cytokinesis, changes in cell shape, amoeboid movement, endocytosis and exocytosis, etc. MFs associate with the protein myosin to generate muscle contractions. Actin filaments/MTs assembly from monomeric actin/tubulin is caused due to energy expenditure, where ATP/GTP bound to actin/tubulin is hydrolyzed during polymerization. Finally, intermediate filaments (IFs) are a type of cytoskeletal element composed of a heterogeneous group of structural elements, and they are not found in all eukaryotes. The primary function of the IFs is to contribute to the mechanical support for the plasma membrane where these filaments come into contact with other cells and/or with the extracellular matrix. The IFs are not directly involved in cell movement. All 3 types of cytoskeletal elements (microfilaments, intermediate filaments, microtubules) can be visualized by fluorescence microscopy when cells express chimeric MT/IF/MF.–GFP fusion proteins.

b. Balloons deflate
d. Volume inside bell jar decreases
f. Pressure inside bell jar increases
2. Rubber diaphragm down-
a. Galloons inflate
c. Volume inside bell jar increases
e. Pressure inside bell jar decreases
Explanation:
The rubber diaphragm is the model to demonstart the various parts of the respiratory system and how they move during breathing process. In case of it moves down, the rubber diaphragm is stretched, the volume inside the bell jar increases which causes presursue decrease.
Balloon inhale or sucks in the air from outside and gets inflate. this increases the volume in the jar. The pressure is increased

which fundamental units are involved in force do step Wise
Force = ma
We know, the unit that the S.I. unit of mass is Kg.
We also know that a = (v - u)/t.
We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.
We know that the S.I. unit of d(displacement) is m.
So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.
So, the S.I. unit of a is m/s×s or m/s²
So, the unit of force is
(unit of m) × (unit of a)
= kg × (m/s²)
= kg.m/s²
=
[tex]kg \: m \: {s}^{ - 2} [/tex]
Or more simply,
F = ma
=> F = m{(v-u)/t}
Putting units,
Newton = kg[{(m/s) - (m/s)}/s]
=> Newton = kg{(m/s)/s}
=> Newton = kg(m/s²)
=> Newton = kg.m/s²
=> Newton = kg.m.(s^-2)

Given the latitudinal differences in sunlight intensity, how might you expect the carrying capacity of a plant species found at the equator to compare with that of a plant species found at high latitudes? Explain your answer
Answer:
The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.
define cell and atom
Answer:
Cell: All living organisms are made up of cells, which are the basic building components. Cells also carry the body's genetic material and have the ability to replicate themselves. Cells are made up of several components, each of which serves a particular purpose. Organelles, for example, are specialized structures that perform specific activities within the cell.

A dead zone refers to Group of answer choices a) terrestrial areas in which excessive nitrogen fertilizer has essentially burned the soil, preventing plants and microorganisms from living there. b) oligotrophic areas in water bodies that cannot support life due to lack of nutrients. c) an ecosystem that was cleared of all vegetation for slash and burn agriculture. d) hypoxic areas in water bodies that limit marine and aquatic life.
Answer:
The correct answer is d) hypoxic areas in water bodies that limit marine and aquatic life.
Explanation:
A dead zone are oxygen-deprived regions, that is, they are large bodies of water that contain little or no oxygen, both in the depths and near the coasts in the oceans. Aquatic and marine dead zones can be caused by climate change, a product of human activity. When the temperature is high, the water does not have the same density and there is less exchange between the depths of the hydrogen peroxide and the surface water, and these no longer receive oxygen. Marine fauna, not finding the oxygen necessary for their survival, end up suffocating due to the lack of oxygen. They may also have reproductive problems and diseases, making it difficult for them to survive.
. Imagine the following scenario. A bacteriophage taken for the treatment of cholera infects a cholera-causing bacterium and temporarily enters the lysogenic stage. When the virus re-enters the lytic cycle, it includes some pieces of the bacterial DNA in its own genome. Specifcally, this DNA encodes information for making the cholera toxin. Imagine some of the possible consequences of this scenario. What will happen to the next bacteria that the virus infects
Answer:
The virus will transfer the DNA encoding cholera toxin to the next bacteria it infects, which will make that bacteria cholera-causing.
Explanation:
The process described in this question is a kind of gene transfer in bacteria called TRANSDUCTION. Transduction is the transfer of fragments of DNA from one bacterium to another via a virus called bacteriophage.
As stated in this question, the virus (bacteriophage) infects a cholera-causing bacterium. The bacteriophage moves from lysogenic cycle to lytic cycle and includes some pieces of the bacterial DNA, which encodes information for making the cholera toxin, in its own genome.
This means that the cholera-making toxin DNA is now a part of the virus's genome and hence, will transfer it to the next bacteria it infects in a process called TRANSDUCTION. This will make that bacteria a cholera causing bacteria.
Discuss how important you think it is to protect ecosystems from human-induced change, such as changes in habitat or introduction of invasive species. Should natural conditions be preserved at all costs, should human needs always prevail, or is the answer somewhere in between? Discuss the negative consequences of taking an approach that you disagree with.
Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. ecosystems are vital for human welfare and survival, as they provide us with essential products and benefits.
Over 90% of our food comes from terrestrial ecosystems, which also provide energy, building materials, clothes, medicines, fresh and clean water, and clean air. Protecting wildlife and preserving it for future generations also means that the animals we love don't become a distant memory. And we can maintain a healthy and functional ecosystem.
