The {{c1::photoreceptors of the eye}} contain a pigment that undergoes a chemical change when struck with a photon

Answers

Answer 1

The photoreceptors in the eye are responsible for detecting light and transmitting visual signals to the brain. These cells contain a pigment that is sensitive to light and undergoes a chemical change when exposed to photons.


The pigment in the photoreceptors is called rhodopsin and it consists of a protein called opsin and a small molecule called retinal. When a photon of light enters the eye and strikes the retinal, it causes the retinal to change shape. This change in shape causes the rhodopsin molecule to become activated, which triggers a series of chemical reactions that ultimately result in the generation of an electrical signal. This electrical signal is then transmitted to the brain via the optic nerve, where it is interpreted as visual information.


Photoreceptors are specialized cells in the retina of the eye that detect and respond to light. There are two types of photoreceptors, rods and cones, which are responsible for different aspects of vision. Rods help with night vision and peripheral vision, while cones are responsible for color vision and sharpness.
The photoreceptors contain a pigment called photopigment, which undergoes a chemical change when struck with a photon (a particle of light). This chemical change triggers a series of events that ultimately convert the light signal into electrical signals that can be processed by the brain. The pigment in rods is called rhodopsin, while there are three types of pigments in cones, each responsible for detecting different wavelengths of light (red, green, and blue). The process of converting light into electrical signals is called phototransduction.

Answer:

In this process, the light-independent reactions of photosynthesis are the modelling and the production of glucose. Thus, option "B" is correct.

What is the chemical reaction of photosynthesis?

The chemical reaction of photosynthesis is given as follows;

6CO₂(g) + 6H₂O(l) + Energy from light → C₆H₁₂O₆(s) + 6O₂(g)

Six molecules of gaseous carbon dioxide (CO₂) combine with six molecules of liquid water (H₂O) in the presence of energy from Sunlight  to produce  one molecule of solid glucose (C₆H₁₂O₆) and six molecules of gaseous oxygen (O₂)

how to build the building blocks of lipids?

Answers

The body needs lipids, which are macromolecules that have a variety of uses in the body, including cell signaling, energy storage, and structural support.

Fatty acids, which have a long chain of carbon atoms with a carboxylic acid group (-COOH) at one end, are the basic units of lipids.

The presence or absence of double bonds between carbon atoms determines whether fatty acids are saturated or unsaturated. Unsaturated fatty acids often have one or more double bonds and are liquid at normal temperature, whereas saturated fatty acids have none and are typically solid at ambient temperature.

Glycerol, a three-carbon alcohol molecule that forms the core of many different types of lipids including triglycerides and phospholipids, is another component of lipids outside fatty acids.

Answers

It should be sand stone then shale then lime stone and then basalt. This is cause the sand and trilobites were at the bottom of the ocean the shale and ammonite were above them but not above lime. Basalt is last because it’s caused by lava or hot matter cooling quickly in water so lime has to be below basalt yet above sand and shale. The fossil in lime wouldn’t be below trilobites or ammonites because they were some of the first.

Based on the provided information, the rock layers can be arranged from oldest to youngest as follows: shale with ammonite (oldest), Limestone with unknown fossils, Sandstone with trilobite, and basalt (youngest).

This arrangement is based on the principle of superposition, which states that in an undisturbed sequence of sedimentary rocks, the oldest rocks are found at the bottom and the youngest rocks are found at the top. Since the shale with ammonite is mentioned first and the basalt is mentioned last, we can infer that the shale layer is the oldest and the basalt layer is the youngest among the given options.

what is the most important advantage of pfu polymerase over taq polymerase?

Answers

Taq polymerase is an enzyme utilized in molecular biology to help with the polymerase chain reaction (PCR). It was initially separated from Thermus aquaticus, a bacterium found in a natural spring in the Lower Geyser Basin of Yellowstone National Park.

The most important advantage of Pfu polymerase over Taq polymerase is the proofreading ability of Pfu polymerase. Taq polymerase doesn't have a proofreading ability, which implies that it doesn't have a 3' to 5' exonuclease action. This leads to a high error rate and the likelihood of mutations during DNA replication. Pfu polymerase (Pyrococcus furiosus) is a DNA polymerase. The archaea P. furiosus is a hyperthermophilic bacterium that grows optimally at 100 °C. Pfu polymerase is thermostable and can endure high temperatures, just like Taq polymerase. Nonetheless, it likewise has a 3' to 5' exonuclease activity that permits it to proofread the DNA strand that it is copying and correct any errors that it may find. The most important advantage of Pfu polymerase over Taq polymerase is the proofreading ability of Pfu polymerase.

Adjusting and incorporating the use of a substance into the normal functioning of the body's tissues is known as Metabolic adaptation.

Metabolic adaptation is the process of adjusting and incorporating the use of a substance into the normal functioning of the body’s tissues. This process is necessary for the body to become accustomed to the presence of a new substance, whether it is from a medication, a food, or an environmental toxin.

As the substance is broken down, the body adjusts its metabolic pathways to accommodate the influx of the new substance and its breakdown products. This process of adaptation helps the body to efficiently process the substance, as well as to minimize any potential harm that it may cause.

Answers

Answer:

Explanation:

Lack of vitamin D causes rickets

Darker skin in  equatorial environments is adaptive because it prevents  vitamin D deficiencies, which cause Rickets in newborns.

What determines skin color?

The pigment melanin is by far the most important factor that determines the color of people's skin, although there are many other factors that play a role. People with darker skin have more melanin, which is the primary pigment responsible for their skin color. Melanocytes, which are cells found in the skin, produce melanin.

People who live closer to the equator typically have darker skin as a form of protection against the sun's ultraviolet (UV) rays. This is because excessive UV exposure can lower folic acid levels and lead to skin cancer.

Black people have more melanin in their skin than people with lighter skin, which affects the body's ability to synthesize vitamin D. People with lighter skin have less melanin in their skin.

Therefore, near equator more sunlight causes increased vitamin D production , preventing rickets in new born.
