Answer:
Anaerobic respiration
Explanation:
In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water.
The process through which the Olympic sprinter's body will likely use to recover from her “oxygen debt” is: an anaerobic respiration.
Anaerobic respiration can be defined as a chemical and biological process that involves the use of electron acceptor rather than oxygen to make energy (adenosine triphosphate) from carbohydrates (sugars).
Hence, an anaerobic respiration can take place or occur in the absence of oxygen.
On a related note, an anaerobic respiration is used to regain lost energy through the actions of electron acceptor when oxygen is lacking in the body.
In conclusion, the Olympic sprinter's body will likely use anaerobic respiration to recover from her “oxygen debt.”

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.

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.
what do you mean by blood circulation
The circulation of blood refers to its continual flow from the heart, through branching arteries, to reach and traverse the microscopic vessels in all parts of the body, reconverging in the veins and returning to the heart, to flow thence through the lungs and back to the heart to start the circuit.
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.
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.

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.
what is the difference between the process of photosynthesis in dark and in sunlight
Answer: The main difference between light and dark reaction is that light reaction is the first stage of photosynthesis, which traps light energy in order to produce ATP and NADPH whereas dark reaction is the second stage of photosynthesis, which produces glucose by using the energy form ATP and NADPH produced from the light.
The difference between the process of photosynthesis in dark and in sunlight is that the light reaction utilizes direct use of sunlight, it runs in the thylakoid region, and the final products are ATP and NADPH. While the dark reaction utilizes an indirect source of sunlight, it runs in the stroma region, and the final product is carbohydrates (glucose).
What is Photosynthesis?Photosynthesis may be defined as the process through which green plants and some algae synthesize their own food (glucose) with the help of carbon dioxide and water in the presence of sunlight.

A day on saturn takes about 10 earths hours. Which fact would best explain this short day?
Answer:
Saturn rotates faster than Earth!
Explanation:
A day is one rotation of a planet, so a planet that rotates faster has "shorter" days.
Hope this helps!
The rotation and revolution of the planets around the Sun determine the length of day and night on the planets. The Earth takes 24 hours to rotate, Mars takes 24.6 hours, while Saturn takes 10 hours.
The fact that described the short day of Saturn is that Saturn rotates faster than the Earth.
It can be explained as:
Earth is the only habitable planet in the solar system, which rotates on its axis in approximately 24 hours. Earth takes 365 days to revolve around the Sun. Mass and density of the planet determine the rotation of the planets. Saturn is a gaseous planet, which is also an outer planet. The day length on Saturn is 10 hours long, which is shorter than the Earth hours.
Thus, Saturn rotates faster than Earth and has a shorter day length.

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

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.
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.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
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.

What four structures are required of all cells?
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.
