People can see bananas as yellow because the yellow color is reflected on the surface of the bananas.
What is the reflection of light?It is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.
Reflected light from a mirror or a still body of water is a common example of reflection, but reflection also impacts other kinds of waves besides light waves. Other waves that can reflect include seismic waves, sound waves, water waves, and particle waves.
All colors are absorbed by the surface of the banana, and only the yellow color is reflected. Therefore, people can see bananas as yellow.

What events likely led to the outbreak of cholera in Haiti?
Haiti suffered a devastating earthquake in January 2010. Subsequently, much infrastructure in Haiti was destroyed, and many residents did not have access to safe drinking water and sanitation. Haiti suffered a devastating cholera outbreak soon after. Cholera is caused by a bacteria: Vibrio cholerae. The disease causes diarrhoea type symptoms. It is thought that the bacteria was introduced to Haiti by Nepalese peacekeepers from the UN. Since there was no safe sanitation, cholera sufferers would have contaminated the water supplies, leading to the spread of the bacteria in drinking water supplies.
The situation in Haiti became very fearful at the time of the earthquake in 2010. These situations result in a poor supply of food, water, and proper sanitation.
What do you mean by Cholera?Cholera may be defined as a disease caused by the bacterium Vibrio cholerae. This disease infects the intestine of the individual.
Cholera is generally spread due to contaminated food and water. Apart from this, It may also be spread due to messy and scattered management of proper sanitation.
Therefore, it is well described above.

While observing some ants, a group of German scientists noticed that the ants had an excellent sense of distance. Wondering how this was possible, they decided to perform an experiment. First, the scientists taught ants to retrieve food from a feeder placed near the ants' home. Then, they removed the lower portion of some of the ants' legs to make them shorter. They also attached tiny stilts to some of the other ants' legs to make them longer. Finally, the scientists watched the altered ants attempt to retrieve food from the feeder. After several trials, the scientists found that the ants with shortened legs walked toward the feeder but stopped short of it. On the other hand, the ants with lengthened legs walked past the feeder. Which of the following conclusions can be made given this information?
A. Altering an ant's leg length has no effect.
B. The ants on stilts were more off balance than other ants.
C. The ants were no longer interested in the food.
D. Ants count their steps while walking.
Answer: Option D
Explanation:
The conclusion is that the ants counts their steps while walking and because of this there was no difference in the number of steps they walked.
The ants with smaller legs stopped before food and the ants with larger legs moved ahead from food.
The study and the experiment shows that the ants count their steps while moving forward. They track the path of other members that move forward them by counting steps.

Which occurrence represents an example of evolution
Examples of evolution include the variation in the peppered moth's color, the similar winter adaptations of the unrelated arctic fox and ptarmigan, and changes in the beak shapes of Galápagos finches due to natural selection.
Explanation:Examples of evolution can be seen in various forms. One of the classic examples often used in biology textbooks is the peppered moth. Changes in the population's allele frequencies in light and dark forms, which represents small-scale evolution, could be traced back to this species.
Another example of evolution is the evolutionary convergence observed in unrelated species sharing the same environments. The arctic fox and ptarmigan, though not related, adapt to white phenotypes during winter to blend with the snow and ice, a testament to similar selection pressures.
Additionally, the Galápagos finches offer an illustration of evolution through natural selection. Shifts in the distribution of beak shapes from one generation to the next, caused by variations in environmental conditions, show how traits passed on can influence survival and reproduction.

Explain using complete sentences where on the HR diagram you would expect to find a main sequence star based on its physical properties.
Explanation:
The Hertzsprung-Russel Diagram also known as HR diagram is stars' scatter plot showing the relation of luminosity or absolute magnitude vs spectral class or surface temperature. The main sequence stars can be plotted on a HR Diagram as a diagonal band as their physical properties vary a lot.
The mass of these stars ranges from about a tenth of that of the Sun to about 200 times the mass of the Sun. Inside these stars Hydrogen fusion results in Helium. 90% of the stars, including the Sun, in the Universe lies in this category.
Their surface temperature lies in the range of 2500 Kelvin to 40000 Kelvin.

Which tool would you use to predict the percentage of offspring that will have a specific trait? Microscope Flowchart Pedigree chart Punnett square
A Punnett square is a diagrammatic tool that is used to predict the percentage of offspring that will have a specific trait during a cross between two parents.
What is a Punnett square?A Punnett square is a very useful tool in the study of genetics which is used to predict the offspring that a cross between two parents will produce.
The Punnett square provides information about the genotype as well as the phenotype of the offspring.
It also provides information about the ratio in which the genotype and phenotype of the offspring occur.

if the mother is heterozygous and the father is heterozygous what is the genotype probabilities?
When both parents are heterozygous for a trait, the offspring have an equal chance of inheriting the four possible genotype combinations 'AA', 'Aa', 'aA', or 'aa'. Phenotypically, this equates to a 3:1 ratio of dominant to recessive traits. The probability of an offspring exhibiting the dominant phenotype is 3/4, and for the recessive phenotype, it's 1/4.
Explanation:If both the mother and the father are heterozygous for a trait, we can use the product and sum rules to calculate the genotype probabilities. In this scenario, we can adopt a method known as a Punnett Square to visualize the possible outcomes. Consider each parent can donate one of two different alleles. Let's denote these alleles as 'A' and 'a'.
Because each parent is heterozygous ('Aa'), the possible allele combinations for the offspring are: 'AA', 'Aa', 'aA', or 'aa'. Each of these combinations, representing the different genotypes, have equal likelihood of occurring. Therefore, the offspring show a genotypic ratio of 1 AA: 2 Aa :1 aa.
Now considering phenotype, the 'AA' and 'Aa' combinations would exhibit the dominant phenotype, and 'aa' would exhibit the recessive phenotype. Hence, if we apply the sum rule of probability, we expect the offspring to show a phenotypic ratio of 3 (dominant):1 (recessive). This means, the probability of an offspring exhibiting the dominant phenotype is 3/4 and the recessive phenotype is 1/4.
