Organisms that undergo Aerobic Respiration include humans and yeast in oxygen-rich environments. Anaerobic Respiration is employed by some bacteria like Shewanella when oxygen is absent. Lactic Acid Fermentation is used by muscle cells in humans and Lactobacillus in yogurt production, while Alcoholic Fermentation is seen in yeast during beer brewing and bread making.
Explanation:Aerobic Respiration occurs in many organisms, including humans. In this process, cells use oxygen to convert glucose into ATP, carbon dioxide, and water. An example of an organism that uses aerobic respiration is the common yeast species Saccharomyces cerevisiae under oxygen-rich conditions.
Anaerobic Respiration is used by certain bacteria that can make ATP without oxygen. These include some species of bacteria in the genus Shewanella, which can utilize other inorganic compounds as final electron acceptors when oxygen is not available.
Lactic Acid Fermentation occurs in muscle cells of animals, including humans, when oxygen is scarce, such as during intense exercise. In this process, glucose is converted into ATP and lactic acid. Lactic acid bacteria, like Lactobacillus, also use this process to ferment milk into yogurt, for example.
Alcoholic Fermentation is used by yeast and some types of bacteria to convert glucose into ATP, alcohol, and carbon dioxide in the absence of oxygen. An example of an organism that undergoes alcoholic fermentation is Saccharomyces cerevisiae when oxygen is not present, such as during the brewing of beer and the making of bread.
Final answer:
Aerobic respiration occurs in humans, while yeast undergoes anaerobic respiration, specifically alcoholic fermentation. Bacteria in yogurt use lactic acid fermentation, and yeast also undergoes alcoholic fermentation.
Explanation:
Aerobic Respiration:
An organism that uses aerobic respiration is humans. During aerobic respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide, water, and energy in the form of ATP. This process is more efficient than anaerobic respiration and allows for the production of a larger amount of ATP for cellular activities.
Anaerobic Respiration:
An example of an organism that uses anaerobic respiration is yeast. During anaerobic respiration, glucose is broken down in the absence of oxygen to produce carbon dioxide, alcohol or lactic acid, and a small amount of ATP. Yeast undergoes alcoholic fermentation, which produces ethanol as a waste product.
Lactic Acid Fermentation:
An example of an organism that uses lactic acid fermentation is bacteria found in yogurt. During lactic acid fermentation, glucose is converted into lactic acid and a small amount of ATP is produced. This process is utilized by bacteria to produce yogurt and other fermented dairy products.
Alcoholic Fermentation:
As mentioned earlier, yeast undergoes alcoholic fermentation. Yeast converts glucose into ethanol and carbon dioxide during alcoholic fermentation. This process is used in the production of alcoholic beverages such as beer and wine.
Remoras, or scker fish, attach themselves to sharks and travel with them. When the sharks feed, the remora detach themselves and feed on pieces of fish the sharks left behind. What two types of interactions are described in this scenario?
a.
Predation and commensalism
b.
Predation and mutualism
c.
Competition and parasitism
d.
Competition and commensalism
The right option is; a. Predation and commensalism
Predation is an interaction between organisms in which one organism (the predator) benefits from another organism (the prey), while commensalism is also an interaction between organisms of different species in which one species benefits from the other without either harming or benefiting the latter. From the question, the remoras benefits from the relationship by living on sharks and feeding on the leftovers of the sharks, but the sharks are not affected in any way. The relationship describes predation and commensalism.

Lactobacillus acidophilus (below) is a probiotic microorganism typically found in the human small intestine. It has a cell wall made of peptidoglycan. It aids in the process of digestion and can commonly be obtained through sources such as acidophilus yogurt. Which characteristic proves Lactobacillus acidophilus is from the specific kingdom Eubacteria?
It is multicellular.
It has a cell wall.
It is a microorganism.
It has peptidoglycan.
The right answer is It has peptidoglycan.
Eubacteria are not multicellular beings, but are unicellular.
Eubacteria certainly have a cell wall, but we must not forget that plant cells also have a cell wall, so this is not really a feature.
Eubacteria are microorganisms but there are eukaryotic microorganisms, so it is not a characteristic.
Peptidoglycan (or murine, or mucocomplex, or mucopeptide) is a characteristic component of the bacterial wall (not found elsewhere) maintaining the shape of cells and providing mechanical protection against osmotic pressure. It forms a thin layer in Gram-negative bacteria and a thick layer in Gram-positive bacteria.

How do plants and other organisms capture energy from the sun?
Compare the energy conversions in lactic acid fermentation to those in cellular respiration. Considering the differences in ATP production, why would a cell undergo lactic acid fermentation?
Answer:
2 ATPs are produced in fermentation and 38 ATPs are produced in cellular respiration
Explanation:
A cell undergo lactic acid fermentation only when there is no oxygen i.e anaerobic condition only. This usually happens when a person do rigorous exercise and the oxygen demand escalate suddenly which is unmet by normal respiration process.
In fermentation, carbohydrates such as starch or sugar convert into lactic acid or alcohol in the absence of oxygen with production of 2 ATP while in cellular (aerobic respiration) nearly 38 ATPs are produced

Question 4.In which state of matter do the particles move somewhat freely but still not enough to fill the entire space of a container?
solid<-- my answer
liquid
gas
Question 5.In which state of matter are the particles the LEAST attracted to each other?
solid
liquid
gas
Final answer:
Neutrons are found in the nucleus and have a neutral charge. The proton has a positive charge, while the electron is negatively charged. Liquids allow particles to move somewhat freely, and gases have particles that are the least attracted to each other.
Explanation:
Neutrons are found in the nucleus and have neutral charge. Therefore, the correct answer is that neutrons are found in the nucleus with a neutral charge.
The particle with a positive charge is the proton. Protons are constituents of the nucleus and carry a positive electric charge.
The particle with a negative charge is the electron. Electrons orbit the nucleus and are negatively charged.
In the state of matter where particles move somewhat freely but not enough to fill the entire space of a container, the correct answer is liquid. Unlike solids, whose particles vibrate but do not move from place to place, particles in a liquid can move around each other, although they are still attracted enough to stay together.
Particles are the least attracted to each other in the gas state of matter, allowing them to fill the entire space of a container.

*width
*length
*velocity
*density
8. The vertical drop of a stream channel over a certain distance is called _____.
*discharge
*channel roughness
*gradient
*runoff
Mass movements are driven by gravity and can range from slow creeps to rapid landslides. The key factors in these phenomena are the steepness of slopes, type of material, and climate. The eroding and transporting power of a stream depends on its velocity, and the gradient defines the stream's vertical drop.
Explanation:The force behind mass movements is, indeed, gravity. Mass movements always trend downslope due to the gravitational force. However, it's not accurate to say mass movements always lead to landslides; they vary in speed and scale. They could be a slow creep or a rapid avalanche.
Oversteepened slopes often lead to mass movements due to their angle being greater than 40 degrees. A block of material moving downslope along a curved surface is commonly referred to as a slump.
A rapid form of mass movement common in dry mountainous regions is rockfall. Water balances in the world environment are maintained since the average annual precipitation worldwide must match the quantity of water evaporated. The power of a stream to erode and transport material mainly depends on its velocity, rather than its width or length.
The vertical drop of a stream channel over a preset distance is described as its gradient.

please anyone?
True or False. Wind blows due to the differential heating of earth's surface.
True
False
Heat's effect on the wind cycle is most easily observed near the sea. During the day, the ocean absorbs heat from the surface, keeping the air above it cooler than above the land. When the warm air rises from the shore, the cooler air from the ocean blows in to take its place. At night, the land cools quickly, while the ocean radiates the heat it absorbed, keeping the air above warm. This reverses the effect, causing the air offshore to rise and creating a breeze from the land. Uneven heating can also occur due geographical features. A mountainside exposed to the sun will warm more than a shadowed valley below it, creating a wind that blows uphill during the day and downhill at night.
The same principle is responsible for global wind patterns. The polar regions receive less solar radiation than areas near the equator, resulting in a global shift in temperature according to latitude. This, along with differences in temperature and density in various layers of the atmosphere, creates global wind patterns like the jet stream that help drive weather systems.

Months after a forest fire, some nonnative plants began to grow in the area. why were these plants able to grow?
Final answer:
Nonnative plants are able to grow after a forest fire due to the increased availability of sunlight and open space after the elimination of the dominant tall trees. This process is part of secondary succession, which leads to the eventual recovery and formation of a new climax community.
Explanation:
After a forest fire, the dominant tall trees that previously shaded the ground and absorbed most of the sunlight are no longer present. This loss of canopy opens the area to sunlight, allowing nonnative plants and pioneer species to grow. These plants are often well-adapted to thrive in the open, sunny, and disturbed conditions that a fire creates. The process through which a forest recovers after a disturbance like a fire is known as secondary succession.
Initially, annual plants and grasses will colonize the area because they grow quickly and can take advantage of the sudden abundance of sunlight and space. As these pioneer species alter the environment, such as by enriching the soil with their decomposing biomass, the area becomes more accommodating for other plants like shrubs and eventually small pine, oak, and hickory trees, referred to as intermediate species. Over time, a new climax community forms, resembling the original forest's species composition.

Sand dunes are formed by _____.
volcanoes
erosion
convergent faults
divergent faults
Answer: erosion
Erosion is the process of removal and displacement of surface soil particles by the effect of wind, water or chemical agent. The sediments due to the effect of these agents gets displaced to locations other than the one where their parent rock or soil originated. A sand dune can be defined as the accumulation of grained sized sand into the shape of ridge by the effect of wind under the influence of gravitational force exerted by the earth. Dunes are formed when the loose sand is blown by wind. Therefore, sand dune is the erosion of sand by wind. Sand dunes are formed in deserts, beaches, barren fields and semiarid regions.

Explanation:
what part of an original isotope number of atoms remains have two half life
Half-life is the time taken by a substance (molecule, drug or other) to lose half of its proportion. Used by extension in the field of radioactivity, the half-life, also called radioactive half-life, is the time at which half of the radioactive nuclei of a source have disintegrated.
The term half-life is often misinterpreted: two half-lives do not correspond to the full life of the product. The half-life is, in fact, the median of the life of a product, that is to say, the duration below which there remains more than 50% of the product, and beyond which there remains less than 50%. So two half-lives correspond to the duration where 50% of the 50% of the product remains, ie 25% (the quarter).
Energy moves in the form of energized.......?
Energy exists in different forms, including chemical, mechanical, radiant, and electrical energy.
Explanation:Energy exists in different forms, such as chemical energy, mechanical energy, radiant energy, and electrical energy. Chemical energy is stored and released as chemical bonds are formed and broken. Mechanical energy directly powers physical activity. Radiant energy is emitted as waves, such as in sunlight. Electrical energy is the power of moving electrons.
Chemical Energy: This is the energy stored in the bonds between atoms and molecules. It's released during chemical reactions. For example, the energy in food is released and converted into other forms when it's digested.
Mechanical Energy: This is the energy associated with the motion or position of an object. It can be either kinetic energy (associated with motion) or potential energy (associated with position). For example, a moving car has kinetic energy, while a book on a shelf has potential energy.
Radiant Energy: Also known as electromagnetic energy, this form of energy includes visible light, radio waves, X-rays, and other forms of electromagnetic radiation. It travels in waves and carries energy.
Electrical Energy: This is the energy associated with the movement of electrons. It's what powers electrical devices and flows through wires to provide electricity for various purposes.

DFG and JKL are complementary angels. m DFG=x+2,and mJKL=x-4. Find the measure of each angle
Answer:
DFG = 48°.
JKL = 42°.
Explanation:
DFG and JKL are the complementary angles.
Complementary angles may be defined as the angles that has the sum of 90°.
∠DFG + ∠ JKL = 90°.
∠DFG = x+2 and ∠ JKL = x-4.
x+2 + x-4 = 90°
2x- 2 = 90°
x = 46°.
DFG = x+2 = 46+ 2 = 48 °.
JKL = x-4 = 46-4 = 42°.
Thus the answer is DFG = 48 and JKL = 42°.
