The wavelength of a light wave with a frequency of 4.5e and speed of 300,000,000 m/s is equal to 24,527,839.097376 meters.
The formula which shows the relation between the wavelength (λ), frequency (f), as well as speed of light (c) is:-
λ = c / f
where the value of c is taken as 300,000,000 m/s, i.e. the speed of light in vacuum.
Now, on substituting the given values in the formula, we get:
λ = c / f
= 300,000,000 / 4.5e
= 300,000,000 / 4.5*2.718 (the value of 'e' is rounded-off to 3 significant digits)
It can be also written as:
= 3 x 10⁸ / 4.5*2.718
= 1 x 10⁸ / 1.5*2.718
= 10⁸ / 4.0770
= 10⁸ x 10⁴ / 40770
= 10¹² /40770
= 10¹¹ / 4077
= 24,527,839.097376 meters
Thus, the wavelength of the light wave is equal to 24,527,839.097376 meters.

I need help with these if do thank you so much
Answer:
13.) D. Is correct answer: "Only the fastest rabbits are able to escape predators," is an example of directional selection.
Option B, "A chicken population with members having different colors of feathers are equally likely to survive," is not an example of directional selection. In this case, there is no selective advantage for any particular feather color, so there is no directional pressure for any one color to become more prevalent in the population over time. This is an example of stabilizing selection, which favors the average trait and selects against extreme variations.
Therefore, option D, "Only the fastest rabbits are able to escape predators," is the correct example of directional selection.
14.) Option G, evolution by natural selection, explains the changes in characteristics of a plant species on an isolated island in response to environmental changes.
—
Genetic drift (option F) is another mechanism of evolution, but it refers to random fluctuations in allele frequencies in a population that are not necessarily tied to selective pressures. Punctuated equilibrium (option H) refers to a pattern of evolution in which long periods of stasis or little change are interrupted by sudden bursts of evolutionary change. Convergent evolution (option J) occurs when different species independently evolve similar traits or adaptations in response to similar environmental challenges or selective pressures, but this is not the best explanation for changes in a single plant species on an isolated island.
—
15.) B. Divergent evolution explains homologous structures, where different species evolve from a common ancestor and develop similar structures for different functions. In this case, the bird's wing and the human arm have the same underlying bone structure, but have evolved to serve different purposes.
16.) Option J, "the environments in which they evolved," would be expected to be the same for these three species with convergent adaptations.
17.) A. Fossil A was found in a sedimentary rock layer below fossil B. Relative dating techniques compare the position of fossils in different layers of sedimentary rock to determine their relative ages. The lower the layer of sedimentary rock, the older the fossils found in it are likely to be. Therefore, if fossil A is found in a lower layer of sedimentary rock than fossil B, it is likely that fossil A is older than fossil B.

57. Transfer RNA serves as a template for DNA during protein synthesis. true or false
The given statement "Transfer RNA will serves as a template for DNA during the protein synthesis" is false. Because, during protein synthesis, tRNA molecules bring amino acids to the ribosome, where they are incorporated into a growing polypeptide chain.
The ribosome reads the sequence of messenger RNA (mRNA) and matches each codon (a sequence of three nucleotides) with a complementary anticodon sequence on the tRNA molecule. This pairing between the codon and anticodon ensures that the correct amino acid is added to the growing polypeptide chain.

Two species of fish live in the same pond. they eat the same kinds of plants. they are eaten by the same water birds. which of the following would increase competition between these two species of fish? Explain why.
a. Average habitat temperate increases
b.population of water birds increases
c.number of food plants increases
d.water level in the pond decreases
The option that would increase competition between the two species of fish is (c) an increase in the number of food plants in the pond.
Competition between two species occurs when both species use the same resources, such as food, water, or habitat. In this case, the two species of fish eat the same kinds of plants and are eaten by the same water birds.
If the number of food plants in the pond were to increase, this would increase the number of resources available to the fish. As a result, the two species would have to compete for the same food resources, and the competition between them would become more intense.
The other options are not likely to increase competition between the two species of fish in this scenario. An increase in average habitat temperature (a) may affect the behavior and physiology of the fish, but it is unlikely to directly impact competition between them. An increase in the population of water birds (b) would likely increase predation pressure on the fish, but it would not directly affect their competition for resources. Finally, a decrease in the water level in the pond (d) may limit the available habitat for the fish, but it would not directly increase their competition for resources.

. In domestic cattle the spotting pattern of the coat can be controlled by several alleles. The Dutch
belt pattern is controlled by a dominant allele “A”. The Hereford pattern is “a1”, a solid pattern is “a2”,
and the Holstein pattern is “a”. The Dutch belt pattern is dominant to all other alleles. The Hereford
pattern is dominant to the solid and the Holstein pattern. The solid pattern is dominant to the Holstein
pattern and the Holstein pattern is recessive to all. So the dominance pattern looks like this: A>a1>a2>a.
Use this information to answer the following questions.
a. Can Holsteins produce Hereford offspring? Explain your answer.
b. Can Herefords produce solid offspring? Explain your answer.
c. Is it possible for two parents with different color patterns to have four offspring all with
different phenotypes? Explain your answer. Include a Punnett square or squares to explain
your answer.
Yes, Holsteins can produce Hereford offspring. Holsteins have the "a" allele, which is recessive to the "A" allele for the Dutch belt pattern, and the "a1" allele for the Hereford pattern.
What is allele?Alleles are different forms of the same gene. Each gene has two alleles, one inherited from each parent. Alleles can be dominant, meaning they mask the effect of the other allele, or they can be recessive, meaning they are only expressed when two recessive alleles are present. Alleles can also be codominant, meaning they each contribute to the phenotype.
a. Yes, Holsteins can produce Hereford offspring. Holsteins have the "a" allele, which is recessive to the "A" allele for the Dutch belt pattern, and the "a1" allele for the Hereford pattern. Since "A" and "a1" are both dominant alleles, the offspring of a Holstein and Hereford parent will have the Hereford pattern.
b. Yes, Herefords can produce solid offspring. Herefords have the "a1" allele, which is dominant to the "a2" allele for the solid pattern. Since "a1" is dominant to "a2", the offspring of a Hereford and solid parent will have the solid pattern.
c. Yes, it is possible for two parents with different color patterns to have four offspring all with different phenotypes. For example, if the father has a Dutch belt pattern (Aa1a2a) and the mother has a Hereford pattern (Aa1aa), the Punnett square would look like this:
