Difference between a Porcupine and an Hedgehog?
Both hedgehogs and porcupines are mammals that have quills. They are both found in Africa, Europe, and Asia; however, some species of porcupines are also found in the north, central and south America. Hedgehogs are smaller in size than porcupines and have quills that are also much smaller.

When threatened, the hedgehog raises its quills upright in a crisscross pattern, making its body pointy and sharp. It uses its belly muscles, back muscles, and extra skin to tuck in its head, legs, and tail to curl into a complete ball, protecting its soft belly. The solid ball of spikes is hard forRead more

The solid ball of spikes is hard for predators to open.

Growls in their basic form are used for short-distance communication. During mild arousal, growls resonate in the trunk and become rumbles while for long-distance communication, they escalate into roars. Low-frequency growls are infrasonic and made in many contexts. Squeaks come in two forms; chirpiRead more

See lessHow does Chameleon change colour?
Chameleons change colour by dispersing or concentrating pigment granules (melanophore cells) in the cells that contain them. In general, the animal appears lighter-coloured when pigment is concentrated and dark when pigment is dispersed throughout the cells. The chameleon's colour state at any givenRead more
Chameleons change colour by dispersing or concentrating pigment granules (melanophore cells) in the cells that contain them. In general, the animal appears lighter-coloured when pigment is concentrated and dark when pigment is dispersed throughout the cells. The chameleon’s colour state at any given time is controlled by a complex interaction of hormones, temperature, and the animal’s autonomic nervous system. Colour change is determined by such environmental factors as light and temperature as well as by emotions—such as fright and the emotions associated with victory or defeat in battle with another chameleon.
See lessWhat is the primary mode of communication for dolphins?
Dolphins communicate using a vast array of sounds and nonverbal gestures. Like humans, dolphins use both verbal utterances and nonverbal gestures to communicate with one another. These include whistles, clicks, and loud broadband packets of sound called burst pulses.

See lessWhich marine creature has the ability to regenerate lost body parts, including limbs and organs?
Several amphibians and fish are capable of regenerating tails and limbs, but axolotls take this ability up a notch by regenerating jaws, spinal cords, skin, ovary and lung tissue, and even portions of their hearts and brains. What's more, an axolotl can continue to regenerate throughout its life. ThRead more
Several amphibians and fish are capable of regenerating tails and limbs, but axolotls take this ability up a notch by regenerating jaws, spinal cords, skin, ovary and lung tissue, and even portions of their hearts and brains. What’s more, an axolotl can continue to regenerate throughout its life.
The regenerative abilities of this animal’s cells are of significant interest to researchers hoping to translate this ability to humans. This is a remarkable capability: If an axolotl loses a limb, it regenerates, perfectly restoring the appendage to the right size and orientation. Within weeks, the junction between the old and new tissue vanishes entirely.

Kangaroos use their muscular tail to support, propel and power their pentapedal gait just like a leg.

See lessATSC-The five main ATSC formats of DTV broadcast in the US are:
480i: Standard definition, which is compatible with NTSC sets
480p: Enhanced definition, which is similar to DVD quality
720p: High definition
1080i: High definition
1080p: High definition, which is used by some cable operators and terrestrial stations
Frame rate-The standard frame rate for television has been 30 frames per second (fps) since the early days. This is still widely used, but producers are moving towards a more cinematic 24 fps.
The transformer that develops the high voltage in a home television is commonly called a…?
The transformer used in a home television is called a flyback transformer, or line output transformer (LOPT). It's a special type of electrical transformer that generates high-voltage sawtooth signals at a high frequency. These signals are important for the scanning process in CRTs.
