Answer: Octopuses and their kin (cuttlefish and squid) stand apart from other invertebrates, having evolved with much larger nervous systems and greater cognitive complexity.
The majority of neurons in an octopus are found in the arms, which can independently taste and touch and also control basic motions without input from the brain.
Octopus brains and vertebrate brains have no common anatomy but support a variety of similar features, including forms of short- and long-term memory, versions of sleep, and the capacities to recognize individual people and explore objects through play.
Explanation:
Answer:
For example, frogs are mostly aquatic; most toads live on land (but near water). Frogs have teeth; toads do not. ... However, toads have glands behind their eyes that can secrete a burning milky toxin
Explanation:
Answer:
Option B.
Explanation:
Decreasing vehicle traffic and industrial emissions.
Answer: Option D) They both have similar intermolecular forces but, overall, water has stronger intermolecular forces.
Explanation:
Since specific heat capacity indicates the amount of heat required to raise a unit of a substance by 1°c; a higher value of 4.184 J/g°C for water justifies that more heat energy is required to break through and raise by 1°c the molecules of water unlike ethanol.
Using the Doppler shift effect
If the celestial body is in the blue shift, then its moving towards earth and if it's in the red-shift then it's moving away from earth.
Explanation:
Doppler shift effect is a phenomenon that occurs in waves due to relativity. When an object is relatively moving toward an observer, it tends to ‘compress’ the waves into a higher frequency/ shorter wavelength. Visible light will be observed in blue shift because blue light is of higher frequency than red. If the object is relatively moving away from the observer, it tends to ‘stretch’ the waves. Remember ALWAYS this is relative to the observer. hence giving them the perception of viewing the object in longer wavelength. The object is observed in red shift because red light it has a longer wavelength/lower frequency than blue light.
This phenomenon is not limited to light waves, but happens even in mechanical waves like sound. When a wailing ambulance is approaching you, you hear it in high pitch. However, when it passes you and moves away from you, you hear it in low pitch.
