The given statement 'A positive magnification means the image is inverted compareed to the object' is false. Because when the image is virtual and erect then magnification is taken as positive.
When the distance is positive, real image is produced. When the distance is negative, virtual image is produced.
Image distance is the distance between the object to the lens of the mirror. When the image distance is positive, it means that the real image is produced in the mirror. When the image distance is negative, it means that the virtual or diminished image is produced in the mirror.
Thus, the above statement is false.

Friction can absolutely causes a moving object to stop (stationary). So, the answer is True.
What is Friction?
It is a type of force that tries to slow down or stop the movement of a moving object when the two surfaces are touching each other.
To stop the object, surfaces also play an important role. For example, Rough surfaces produce more friction otherwise things would be just rolling.
Therefore, friction can cause a moving object to stop.

In which two processes do cells make a small amount of ATP for every
glucose molecule split in two?
A. Glycolysis
B. Fermentation
C. The electron transport chain
D. The Krebs cycle
SUBMI
Answers
Glycolysis and Kreb's cycle are two processes in which cells make a small amount of ATP for every glucose molecule split in two.
Describe glycolysis.
The process by which glucose is broken down to provide energy is known as glycolysis. It generates two pyruvate molecules, ATP, NADH, and water. There is no need for oxygen throughout the process, which occurs in the cytoplasm of a cell.
An overall net of two ATP molecules will be created during fermentation and glycolysis. To prevent glycolysis from ceasing, fermentation will produce 2 ATP, and glycolysis will produce 2 ATP through substrate level phosphorylation. There is no electron transport system involved in fermentation, and no ATP is produced during the fermentation process itself. Two ATP, six NADH +H+, and two FADH2 were created during the Krebs cycle. Due to the two pyruvic acid molecules that enter the system for every glucose molecule, two ATP molecules are produced.

Ocean water is sinking at the North Atlantic Buoy Station. What happens
when water of a high density sinks?
A. It pushes higher-density water toward the ocean's surface.
B. It causes water trapped in nearby ice to melt.
C. It pulls in lower-density water from surrounding areas.
D. It pulls water up the shore in a high tide.
Answers
The North Atlantic Buoy Station is experiencing ocean water sinking. It draws water with a lower density from the surroundings.
What might be causing the ocean water at the North Atlantic buoy station to sink?Ocean water loses heat to the atmosphere in chilly places like the North Atlantic Ocean, where it then turns cold and thick. Sea ice is created when ocean water freezes, leaving behind salt that makes the surrounding seawater saltier and denser. Water that is dense, icy, and salty sinks to the ocean floor.
What transpires when highly dense water sinks?Less dense water floats on top of denser water. The deep ocean currents that travel around the globe are propelled by this theory. Seawater is sufficiently dense to sink into the deep ocean and flow along the bottom of the basins due to a combination of high salinity and low temperature close to the surface.

inquiry based pedagogy is being embraced in principle across the globe. in the last decade , it has been supported by an increasing body of research on its effectiveness. illustrate your understanding of the concept of inquiry based pedagogy with a relevant example
Answers
Inquiry-based pedagogy involves fostering curiosity and active learning. For example, students investigating real-world environmental issues and proposing solutions.
Inquiry-based pedagogy is a teaching approach that promotes active learning and critical thinking through inquiry and exploration. One relevant example of inquiry-based pedagogy is a science classroom where students are encouraged to design and conduct their own experiments. Instead of simply following instructions, students formulate research questions, develop hypotheses, plan and execute experiments, collect and analyze data, and draw conclusions. For instance, students may investigate the effect of different variables on plant growth by manipulating factors like light, water, or soil composition. This approach allows students to engage in authentic scientific practices, develop problem-solving skills, and gain a deeper understanding of the scientific method. By actively participating in their learning process, students develop a sense of ownership and become more engaged, fostering a love for learning and nurturing their ability to explore and discover knowledge independently.For more such questions on Pedagogy:

The greatest change in the rate of photosynthesis occurs when the light level is __________3__________. Which table contains the numbers and terms that correctly complete the statements?
Answers
Answer:
A:
increaseslightlowExplanation:
Photosynthesis is a chemical process in plants and other primary producers that is integral to energy production. Carbohydrates containing energy is made from light, water and carbon dioxide in the form of glucose molecules.
As a result, the waste product oxygen is released. Photosynthesis is a rate-limited reaction, depending on many factors, including the concentration of carbon dioxide, atmospheric temperature and intensity of light. Because the energy needed is derived from photons, i.e. light particles, lower light intensities lower the rate of photosynthesis significantly.
Early scientists were conflicted about the mechanism by which cells were created, with some scientists holding the viewpoint that cells were spontaneously crystallized in what was known as free cell formation. Robert Remak discovered ways to fix and observe cell membranes in various stages of cell division. These findings led Rudolf Virchow to proclaim in 1855, Omnis cellula e cellula (every cell comes from another cell), thus completing the tenets of cell theory.

Answer: All cells come from preexisting cells.
Explanation:
The given paragraph is about cells develop from the preexisting cells. The doubling of the genetic material in the S-phase is the triggering mechanism for cell division. In the process of mitosis the genetic material get reduced. The daughter cells vary by the amount of genetic material they receive. This proves that the new cells form from the pre-existing cells.

white eyes are recessive in flies. can two red eyed flies have white eyed offspring
Answers
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies :
Red eye (R) is dominant trait. White eyes (r) is the recessive trait.When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square :
Rr X Rr
Alleles R r
R RR Rr
r Rr rr
In the offspring, the probabilities are:
50% heterozygous individuals Rr, with red eye phenotype. 25% pure dominant individuals RR, with red eyes 25% individuals with the recessive rr genotype, white eyes.This is the possibility of two red-eyed flies having white-eyed offspring.

Why does it take longer for a folded wet towel to dry?The surface area closely relates to evaporation. Evaporation is inversely correlated with surface area or vice versa. Folding a wet towel reduces its surface area and slows evaporation, which makes drying take a long time.
Why does it take wet clothing longer to dry on a humid day?Because of the excessive humidity in the summer rain, clothing dries more slowly. The rate of evaporation slows down in the wet summer. Because there is no sun to shine on the garments, humidity is the amount of water in the air. The difference affects how quickly or slowly the material dries.
Why does a windy day make clothes dry more quickly?A windy day will have a high wind speed, which causes more water to evaporate. The amount of water vapor in the air decreases as wind speed increases due to the scattering of water molecules. As a result, on a windy day, garments dry more quickly.
