Hurricane.
Explanation:
Hurricane and tornadoes are the catastrophic events that occur when the warm air from the gulf of Mexico and the cold air from the north combines together. These hurricanes and tornadoes causes a lot of damage and destruction if the speed and intensity are higher. These hurricanes produced in different region and causes destruction in another region due to its mobility.
A student likes to attend football games, no matter how cold and snowy the weather becomes. She is going to a game on a very cold day and takes along a hand warmer. She activates it and tucks it into the glove she is wearing. She holds her hands together, and before long, her hands are warm. Which best describes how her hands were warmed?
a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
b: Heat was transformed by convection, resulting in the conservation of energy
c: Thermal energy was transferred by currents, resulting in an increase in kinetic energy.
d: Heat was transformed by radiation, resulting in an increase in kinetic energy.
Answer:
The correct answer is - a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
Explanation:
Conduction is ne of the het transfer method where particular substance is heated and increase the kinetic energy which leads to the molecules to vibrate more and move or jump to the particles present in neughbouring substance and transfer some part of the enrgy.
This transfer is a continuous process untill both end become of same temperature of have same kinetic energy, In this case, heat is tranfer ffrom hand to gloves and to the other hand which are hold together after activating them.

explain digestion Process
Answer:
Digestion is the process of converting complex food any individual eats, into the smaller components and nutrition that is absorbed and assimilated into the body to produce energy and nutrition for the cell and body. The digestion process takes place in the digestive system that includes the gastrointestinal tract and organs like the liver and pancreas.
It includes ingestion of food through the mouth or buccal cavity, propulsion of food, physical digestion by making it small pulp with help of peristalsis, chemical digestion by the enzymes and acid, absorption through the intestine into the blood, and defecation of waste.

Which of the following forms of plant reproduction is likely to produce a new plant that is different from the parent plant?
Answer:
Sexual Reproduction
Explanation:
Asexual reproduction is when the parent reproduces by its self and the offspring that comes from it has the same genes as the parent and sexual reproduction is when the off spring has different genes because there are more than 2 parents so if the plant is different and my child looks different from me and i sexually reproduced with someone that means the plant has been sexually reproduced.(can i get brainliest)
Which of the following would lead to a lower rate of photosynthesis?
A
decrease in CO2
B
decrease in O2
C
increase in CO2
D
increase in O2
Answer:
A. Decrease in CO2
Explanation:
This is due to the fact that in photosynthesis plants use carbon dioxide, water and sunlight to make sugar and oxygen. So Oxygen would have no impact on the rate photosynthesis occurs. And a increase in CO2 would increase its rate. Only when there is a lack of CO2 will the plant rate be impacted

Reina is making museum exhibits about two different rock types. How could energy have played a role in the different rock types forming? *
a. Energy causes different types of rock to change in different ways. Energy changes igneous rock into liquid rock and changes sedimentary rock into small pieces of rock.
b. Energy caused one rock type to form, but not the other. Rock that forms because of energy is a different type of rock than rock that forms without energy.
c. Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces.
d. Energy changes rock on different continents in different ways. Each continent on Earth has different rock that might form liquid rock or small rock pieces when exposed to energy.
Answer:
c. Energy from different sources leads to different types of rock. Energy inside Earth melts rock into liquid rock, but energy from the sun causes rock to weather into small pieces.
Explanation:
Energy is the ability to do work. The availability of energy in a system leads to diverse changes.
A rock is an aggregate of minerals and they are formed in diverse ways.
It is the internal heat energy of the earth that causes rocks to melt into liquid rock. The liquid rock is called magma and on getting to the earth surface, it is a lava. Also, the surface processes driven by the external heat engine causes the weathering of rocks into smaller bits and fragments. Both the internal and external heat engine are energy sources that causes rocks to change from one form to another.what is this?? pls help

Cells start to divide when they receive a signal. They continue to divide until they get another signal to stop. A cell with damaged DNA may not respond to the stop signal. The cell can become cancerous and divide uncontrollably. The cancerous cell and all its daughter cells can form a tumor. During which step of the cell cycle does a cell get a signal to begin cell division?
Answer:
Prophase.
Explanation:
Prophase is the stage of cell cycle which receive the signal to start cell division. Due to this signal, the nucleus dissolves inside the cell and the chromosomes begin movement to the middle line of the cell where these chromosomes condenses and then division of the cell occurs in later steps of mitosis cell division. So we can conclude that prophase step started when it got signal.

Pharyngolaryngectomy involves surgical excision of the hypopharynx and larynx, reported with codes 31390 or 31395, and these codes are differentiated based on with or without ______________.
Answer:
The answer is "Complications"
Explanation:
Pharyngolaryngectomy is an operation to eliminate/remove the larynx (voice box) and the pharynx (the territory at the rear of the mouth and throat). The activity is intense, requiring a general anesthetic and a stay of a little while in medical clinic. Now and then it should be completed in two phases, the subsequent stage being to revamp the structures in your neck however much as could reasonably be expected. This will expect unions to be taken from your chest, back or lower arm.
You should be offered broad pre-operative guiding in anticipation of the deficiency of your voice, in spite of the fact that it is conceivable to recapture a decent measure of vocalization with language instruction. After the activity you should inhale through an opening in your neck which will be a permanent feature.
Explain Lamarck's ideas about how organisms changed over time.
Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.Body structures can change according to the actions of the organism.have an innate tendency toward complexity and perfection. The actions of organisms as they use or fail to use body structures.
Lamarck claimed that organisms changed how they behaved in response to environmental change. Their altered behavior caused their organs to undergo modification, which their progeny inherited.
What are the main points of Lamarck's theory of evolution?Lamarck asserts that when the environment changes, animals develop new demands (besoins). This results in novel behaviors that make use of already-existing organs.
Darwin proposed hypotheses like inheritance, different survival, species variety, and extinction, whereas Lamarck proposed theories like the inheritance of acquired features, use and disuse, growth in complexity.
According to Lamarck's theory of evolution, an organism's traits that evolve over the course of its existence in reaction to its environment are inherited by or passed on to its children.

It is important to protect water near the coast from sediment that may enter when land is disturbed for construction. This is because excess sediment may
Answer:
Excess sediment in water may cause a reduce in light penetration decreasing algae's(an important food source) ability to photosynthesize therefore not allowing it to grow. It will stop fish from seeing well enough to move around or feed. Sediment can clog fish gills, reducing resistance to disease and lowering growth rates.Certain chemical pollutants bind to sediment and so if there is excess sediment it can very rapidly change the water quality. These
chemicals that bind to the sediment are dangerous to small animals and plants as well as larger forms of life.
Explanation:
Single-celled pond organisms have contractile vacuoles that maintain water balance within each cell. This is a an example of what scientific principle?
Answer:
The correct answer is homeostasis.
Explanation:
A self-regulating procedure taking place within an organism, which permits them to sustain a stable internal condition level is termed as homeostasis. In case, if an organism fails to sustain homeostatic balance, the eventual result would be death. Water balance, temperature, salt concentration, and pH are some of the several internal conditions, which are required to maintain comparatively stability.
Some of the single-celled pond organisms like paramecium comprise contractile vacuoles, which remove additional water out of the cell. As water balance is a part of sustaining homeostatic balance for an organism, thus one can study homeostasis by witnessing the modifications within the contractile vacuole when the species is placed in distinct solutions.
All cells can synthesis ATP by way of glycolysis. Many cells have to metabolize pyruvate without oxygen by doing...?
Answer:
Anaerobic respiration
Explanation:
As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.
The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.
what do you mean by blood circulation

1.what did magnesium and oxygen atoms had to do to bond ?
2. why did the oxygen atom needed two sodium atoms to bond ?
3. why did the magnesium atom needed two fluorine atoms to bond ?
please put the numbers in order so i know which answer is for the questions thanks <3
Answer:
1. Magnesium and oxygen atoms bond to form an ionic compound; this is evident because one forms a cation and the other an anion. When an ionic compound is formed, one atom "steals" an electron (or electrons) from another. In this case, an oxygen atom (which is pretty electronegative by the way) "steals" 2 electrons from a magnesium atom. The resulting oxygen anion and magnesium cation attract one another to form a bond (more specifically, an ionic one).
2. The oxygen atom needed two sodium atoms to bond because it needs two additional electrons to achieve a stable octet of electrons. 1 sodium atom provides 1 additional electron after it is "stolen" by oxygen, so 2 sodium atoms are needed in total to form the bond.
3. The magnesium atom needed two fluorine atoms to bond because it needs to lose two electrons to achieve a stable configuration/octet of electrons. 1 fluorine atom "steals" one electron, so 2 are needed in total.

Scientists are concerned that melting glaciers are exposing long frozen animals. When the ice melts, the animals thaw and begin to decompose. How will this affect the amount of co2 in the atmosphere?
As the Earth warms, scientists worry that some of the carbon in permafrost could escape to the atmosphere as carbon dioxide or methane. Increasing the amount of these gases in the atmosphere could make Earth's climate & more
Explanation:yw
The process of decomposition increases the amount of carbondioxide gas in the atmosphere.
The process of decomposition greatly affect the amount of carbondioxide in the atmosphere because in the process of decomposition, carbondioxide is released in the atmosphere which is added to the carbondioxide present in the atmosphere.
This results in more warm temperature of the earth atmosphere so we can conclude that the process of decomposition increases the amount of carbondioxide gas in the atmosphere.

How is energy released from a molecule of ATP?
Answer:
When ATP is broken down to ADP
Explanation:
Energy is released from a molecule of ATP when the substance is broken down to ADP
ATP is the energy currency of a cell. It is called Adenosine Triphosphate
When a phosphate is removed, it become ADP - Adenosine Disphosphate.
In like manner, the breaking down releases inherent chemical energy and converts it to other forms of energy.
This is how the body system derives sufficient amount of energy for every of its activities.
When an organism undergoes cellular respiration, this is the process that is in play to release energy needed for the body to function

i) predict which of the liquids would cause the largest decrease in mass of potato stick
PLEASE PLEASE HELP ME I HAVE 10 MINUTES ONLY, I WILL GIVE YOU THE BRAINLIEST!!
Answer:
1 mol per dm3 sodium chloride solution
Explanation:
The liquid that would cause the largest decrease in the mass of the potato stick would be the one with 1 mole per dm3 sodium chloride solution.
The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.
Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.
