Why do you look better in the mirror than in pictures? This is because the reflection you see every day in the mirror is the one you perceive to be original and hence a better-looking version of yourself. So, when you look at a photo of yourself, your face seems to be the wrong way […]

What are the 3 stages of cell signaling? The three stages of cell communication (reception, transduction, and response) and how changes couls alter cellular responses. How a receptor protein recognizes signal molecules and starts transduction. What are the 3 types of cell communication? There are three different types of basic cell communication: surface membrane to […]

How did Dmitri Mendeleev impact the world? Lived 1834 – 1907. Mendeleev’s wish led to his discovery of the periodic law and his creation of the periodic table – one of the most iconic symbols in science: almost everyone recognizes it instantly: science has few other creations as well-known as the periodic table. Can you […]

What is the function of pupil of eye? The function of the pupil is clearly that of controlling the amount of light entering the eye, and hence the light reflex. Can an eye repair itself? Minor superficial scratches on the cornea will usually heal by themselves within two to three days. In the meantime, some […]

How do you get a bottle cap off without an opener? Try grabbing the neck of the bottle as close to the cap as you can get with your non-dominant hand. Position the spoon under the lip of the cap and, using the base of your thumb as leverage, pry the cap loose. Open your […]

What is the effect of pressure in change of state of matter? Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the […]

How do you solve time problems in physics? To solve for time, divide the distance traveled by the rate. For example, if Cole drives his car 45 km per hour and travels a total of 225 km, then he traveled for 225/45 = 5 hours. How do you solve a physics problem? Focus on the […]

Why do moms love sons more than daughters? A new survey suggests that mothers are more critical of their daughters, more indulgent of their sons. … More than half said they had formed a stronger bond with their sons and mothers were more likely to describe their little girls as “stroppy” and “serious”, and their […]

Which of the following will increase the energy of a photon? The energy of the photon depends on its frequency (how fast the electric field and magnetic field wiggle). The higher the frequency, the more energy the photon has. As the frequency of a photon goes up, the wavelength () goes down, and as the […]
