The wavelengths of light are absorbed by chlorophyll as it absorbs light in the red and the blue regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.
What is wavelength?Wavelength has been the distance between two identical or similar positions it means that it is the distance between crests or trough in the adjacent cycle of the waveform.
Wavelength is denoted by (lambda).
It is measured in meter, or centimeter, or millimeters.
Mathematically,
Wavelength is equal to velocity divided by frequency,
So,
Wavelength (lambda) = Velocity/frequency.
Velocity is in meter per second.
Frequency is in 1/second.
Prism is a transparent object in which if sunlight is passed then it will be split in a VIBGYOR
where V = vilot, I = indigo, B = blue, G = green, Y = Yellow, O = orange, R = red.
In this series wavelength of red is higher and violet is smaller and frequency of violet is higher and red is smaller.
Therefore, The wavelengths of light are absorbed by chlorophyll as it absorbs light in the red and the blue regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green.

Which development in plants has contributed to the evolution of large trees?
Answer:
Secondary vascular growth
Explanation:
Secondary growth in the plant allows them to be thicker, unlike primary growth that is apical. Secondary vascular cambium acts as a support for plants especially trees as they grow taller –allowing them to support their own weight. This is what is perceived as wood (secondary xylem) in a tree.
what is the function of meristem
Primary meristematic tissue helps the plant increase in length or vertical growth, meaning it helps the plant grow up toward the sun and down into the soil. It also helps a plant grow in thickness so that the roots and branches are stronger.

Answer: Hydrolysis
Explanation: It is hydrolysis. In hydrolysis, larger molecules, such as polymers, are broken down into their monomers by the action of an enzyme and the addition of a water molecule.
A hydrolysis reaction involves the breakdown of large molecules by enzymes and the addition of water.
Explanation:The breakdown of large molecules by enzymes and the addition of water is known as a hydrolysis reaction. The term hydrolysis is derived from 'hydro-' which means water and '-lysis' which means to break down. In the process of hydrolysis, a water molecule is added to the substance, which causes the substance to separate into two parts. This is an important process in many biological systems, such as the digestion of food in the body.
Enzymes act as catalysts, facilitating this reaction by lowering the activation energy required for the hydrolysis to occur. Hydrolysis is essential for various biological processes, such as digestion, where complex carbohydrates, proteins, and fats are broken down into their constituent monomers like glucose, amino acids, and fatty acids. These monomers can then be absorbed and utilized by the body for energy production and various cellular functions.

How someone’s brain living with adhd can perceive information from outside world that could turn impact performance in class?
Final answer:
ADHD affects students' ability to focus, process information, and behave in ways considered appropriate in the classroom. It can lead to missed deadlines, inattentiveness, and academic struggles, and requires understanding and support from educators for effective learning.
Explanation:
How ADHD Affects Classroom Performance
ADHD, or Attention Deficit/Hyperactivity Disorder, can significantly impact how students perceive and interact with the world around them, which influences their academic performance. Students with ADHD might exhibit high levels of frustration and distraction. These manifestations often lead to perceived inappropriate behavior, difficulties in meeting deadlines, errors in work that appear careless, and challenges in following instructions, all of which contribute to struggles within the educational setting.
Moreover, ADHD is not just a childhood concern as previously thought, but a condition that affects individuals across all ages. This misunderstanding can result in inadequate support for students who continue to struggle with the condition into adulthood. Mental health conditions, including ADHD, can have comorbidity with disorders such as depression and OCD, complicating the educational experience further.
Mental health disorders can distort a student's ability to focus, process new information, and impact attendance due to issues such as anxiety and sleep disturbances. Teachers and educators need to recognize and adapt to these challenges to support individual learning needs effectively.
tp-37 who should you call first if you have an oil or fuel spil?
Call the U.S. Coast Guard National Response Center.
Answer:
You should call the US Coast Guard National Response Center.
Explanation:
The Coast Guard is a national institution responsible for providing various maritime services, usually related to authority. The term refers to institutions with responsibilities that can vary widely, from country to country. Thus, depending on the country, the nature of its coastguard can range from a heavily armed military force with broad powers of police authority, to a simple organization of volunteers with functions limited to maritime search and rescue without any authority.
A certainty is that the Coast Guard is responsible for controlling or resolving possible marine disasters, so if an oil or fuel leak occurs, it is best to call the US Coast Guard National Response Center for this leak to be contained as soon as possible.

A.Yes, sunlight makes plants live.
B.No, sunlight does not make plants grow.
C.If we place a plant in the shade, then it will die.
D.If we place two plants in sunlight, then they will grow differently.
All living things need water and food. Light is nourishment for plants. They use it in a vital process known as photosynthesis, where chloroplasts capture the energy of light, sparking multiple metabolic reactions — one of which creates plant sugars (food).
So your answer would be A. Yes, sunlight helps plants to live
In simple dominance, what is the result when a dominant allele pairs up with a recessive allele?
Offspring display both forms of the trait.
Offspring display an intermediate form of the trait.
The dominant form of the trait shows.
The recessive form of the trait shows.
In most cases, the dominant form of the trait shows.
Answer:
Option C, The dominant form of the trait shows
Explanation:
In simple dominance the trait associated with the dominant allele is expressed while the trait associated with the recessive allele is oppressed. For example –
Let’s assume a flower in which the dominant allele trait is red color and the recessive allele trait is white color. When an offspring of this flower is produced containing one dominant allele and one recessive allele, the color of it would be red only because only the dominant allele expresses its trait.
Hence the correct answer is option C

In an ecosystem when an organism lives together interdependently on biotic factors or other organisms is called an ecological relationship. It can be a favourable or negative relationship.
Mutualism is the relationship between lichen - cyanobacteria and the fungi.
Classification of Ecological association:Commensalism is a type of optimistic relationship in which one organism gets profited from another through modes of food, shelter, locomotion etc. Example orchids growing on other trees.Predation is an ecological relation in which the predator chases and kills the target for food. For example, snakes hunting mice and rabbits.In an ecosystem, two diverse species contest for the same elements is called competition. For example tigers and lions hunting for deer.Parasitism is an unfavourable biological relation in which one species profits from the hosts by harming them in certain ways. For example, ticks living on cats and dog fur.Mutualism is a positive relationship in which both species benefits from each other by working together. For example, cyanobacteria produce food through biochemical processes and share it with fungi and in return, the fungus provides them with a place to live.Thus, option E. mutualism is the relation exhibited by lichen cyanobacteria and the fungi.

4)volcanic activity
5)solar energy
Answer:
Options (1), (3), (4) and (5)
Explanation:
The factors that are needed to study in order to understand better about the long-term climate changes are the position of the earth with respect to the sun, type, and intensity of the tectonic and volcanic activities and also the amount of solar energy entering into the earth's atmosphere.
If the position of the earth changes with respect to the sun and also if changes occur in its plane of orbit, then there will be significant changes in the climate of the earth.
Rapid and high intensity tectonic and volcanic activities can also lead to the increase in the earth's global temperature as it will produce a large amount of gases and dust particles from the volcanoes that are trapped in the atmosphere and does not allow the sunlight to reach the ground surface. Thus, affecting the earth's climate.
The increasing amount of solar radiation can also enhance the earth's climate as it will significantly warm the surface of the earth.

A scientist crossed a pea plant with a green pod and a pea plant with a yellow pod. The scientist collected 100 seeds from the cross. The table shows the trait for pod color observed when the plants from the cross were grown. Which statement correctly explains why all the offspring have the trait for a Yellow pod? A) Genes were inherited only from the plant with a Yellow pod, so only the gene for a Yellow pod was expressed.
B) Genes were inherited only from the plant with a Green pod, but only the gene for a Yellow pod was expressed.
C) Genes for both a Green pod and a Yellow pod were inherited, but only the gene for a Yellow pod was expressed.
D) Genes for both a Green pod and a Yellow pod were inherited, so the genes for both types of pods were expressed.
Answer: C) Genes for both a Green pod and a Yellow pod were inherited, but only the gene for a Yellow pod was expressed.
Explanation: In a diploid organism as the pea plant, a single gene has two alleles or versions, one on each chromosome. Each of these alleles can either be dominant or recessive.
Dominant alleles, such as that producing a yellow pod, will mask the contribution to the phenotype of the second allele, which is recessive. Here, the yellow pod allele will mask the contribution of the green pod allele. Thus, the offspring will have the phenotype (pod color) yellow.
However, both alleles for pod color will be present in the offspring as each parent will provide one chromosome during sexual reproduction.
