The pigment that traps energy in plants is chlorophyll.
The pigment that traps energy in plants is called chlorophyll. Chlorophyll is a green pigment found in the chloroplasts of plant cells. It absorbs light energy from the sun during the process of photosynthesis and uses it to convert carbon dioxide and water into glucose and oxygen.
Chlorophyll has a structure that allows it to absorb light in the red and blue regions of the electromagnetic spectrum, while reflecting green light. This is why leaves appear green to our eyes.
Other pigments, such as carotenoids, may also be present in plants and can assist in trapping additional energy from different wavelengths of light.

Energy is primarily trapped by the pigment chlorophyll in plants, which absorbs light and initiates photosynthesis. Other pigments like chlorophyll b and carotenoids each absorb specific light wavelengths. This energy is passed along until reaching a reaction center where it is accepted and converted to a useful form.
The primary pigment involved in the trapping of energy is chlorophyll, specifically found in plants, algae, and cyanobacteria. Chlorophyll absorbs light energy, particularly in the range of 700 nm to 400 nm (photosynthetically active radiation), and initiates the process of photosynthesis. This energy then becomes harnessed and usable by the organism.
Moreover, there are other pigment types, like chlorophyll b and carotenoids, each identified by specific wavelengths of light they absorb. Similarly, the human eye contains pigments capable of absorbing light to enable vision. However, any energy levels that are higher or lower than these specified ranges can either be insufficient to excite an electron or be too intense, leading to the destruction of the molecules through a process called bleaching.
Once the light energy is absorbed by these pigments, it is passed on from molecule to molecule until it reaches a reaction center. At this reaction center, the energy is accepted by a primary electron acceptor pigment or another organic molecule and becomes useful. It's essential to note that until the energy reaches this center, it's merely energy transfer, not electron transfer.

The statement "Today people with very short sight can wear glasses with thinner lenses because the lenses do not need to be so powerful" is true.
Yes, this statement is true. People with very short sight (myopia) require corrective lenses that are concave in shape to help focus distant objects properly on the retina. The power of the lens is determined by the degree of myopia – the more nearsighted a person is, the stronger the prescription needed.
Advancements in lens manufacturing and design have allowed for the creation of high-index lenses. These lenses are able to bend light more efficiently than traditional lenses, meaning that they can achieve the required optical correction with less material. As a result, people with high prescriptions, whether for nearsightedness or other vision issues, can wear glasses with thinner and lighter lenses while maintaining the necessary corrective power. This has greatly improved comfort and aesthetics for individuals who require strong corrective lenses.

Arabic is the most commonly spoken language in the Sahara.
The Sahara is an African desert that is inhabited by several people (about 2.5 million) from different origin and with different languages. Arabic is the most commonly spoken language in the Sahara. Other languages include Berber, Beja and Guanche. The Sahara contains 11 countries which include Sudan, Morocco, Niger, Chad, Mali and Libya and it is very large with a land area of about 9,400,000 square kilometers.
Answer:
The process of speciation leads to the formation of new species by preventing the flow of genes between the populations.
Speciation is a natural phenomenon by which new species are formed with the help of other processes such as natural selection, genetic drift, mutations, geographic isolation, reproductive isolation et cetera.
In geographic or reproductive isolation, the flow of genetic material is prevented among the populations.
With time, due to the accumulation of genetic changes, the populations can no longer interbreed and thus, results in the production of new species.

diffusion
The laboratory setup would most likely be used to demonstrate the process of diffusion.
A Laboratory may be defined as a place where a variety of experiments may be performed depending on the work or projects it handles.
In this experiment, an artificial cell containing glucose and starch solution is dipped into the water containing a starch indicator.
The concentration of glucose or starch is found to be high in the artificial cell, hence, it removes the water or particles from the inside to the outside of the cell.
Diffusion may be defined as the movement of particles or matter from a region of high concentration to a region of low concentration.
Therefore, the laboratory setup would most likely be used to demonstrate the process of diffusion.
