The trichromatic theory best explains color vision in humans. This theory suggests that there are three types of cones in the retina that are sensitive to different wavelengths of light, allowing us to perceive a wide range of colors.
Spermatids are stored in the seminiferous tubules of the testes in humans. They are formed from the process of spermatogenesis and eventually mature into spermatozoa (sperm cells).
Yes, it is possible for humans to make gold through a process called nuclear transmutation, where elements are transformed into gold by changing the number of protons in their nuclei. However, this process is complex, expensive, and not commonly done on a large scale.
It explains why the planets remain in in orbit around the sun. Also, why moons orbit their planets. It also explains why humans remain on earth.
Energy for humans is derived from the food and drinks we consume, which our bodies then convert into usable energy through a process called metabolism. This energy is used by our bodies to carry out daily activities, such as breathing, circulating blood, and moving muscles.
On average, humans use about 5-10% of their daily energy expenditure on breathing. The energy is mainly used for the muscles involved in the breathing process and to warm, filter, and humidify the air we breathe.
The trichromatic theory of color vision is based on the premise that there are three classes of cone receptors subserving color vision. And usually, humans are trichromatic.
Dichromatic vision is when an individual can only perceive two primary colors, usually blue and yellow. This is commonly seen in some animals, such as dogs. Trichromatic vision, on the other hand, is when an individual can perceive three primary colors, typically red, green, and blue. Humans have trichromatic vision, allowing us to see a wider range of colors compared to those with dichromatic vision.
It explains that modern humans are the result of a long-going and ongoing process of reproductive variation and differential reproductive success, punctuated by divergence between subpopulations and subsequent speciation events.
Carbon dating
you have a big brain
Oldest bones unearthed.
Thirst!!!!
Light is what humans process faster
The theory you are referring to is the opponent process theory of color vision. This theory suggests that the visual system processes colors in three antagonistic pairs: red-green, blue-yellow, and black-white, which helps explain color vision and afterimages in humans.
Chimps have all the same sense organs as humans---nose to smell (maybe a bit better than humans), eyes to see (same trichromatic color vision), skin and same kinds of neurons to feel, similar taste buds (but not exactly the same) to taste, and fairly similar ears to hear.
