Answer: Some mammals live in water all have hair or fur.
Explanation:
Answer:
Classical conditioning (also known as Pavlovian or respondent conditioning) is learning through association and was discovered by Pavlov, a Russian physiologist. In simple terms, two stimuli are linked together to produce a new learned response in a person or animal.
The most famous example of classical conditioning was Pavlov's experiment with dogs, who salivated in response to a bell tone. Pavlov showed that when a bell was sounded each time the dog was fed, the dog learned to associate the sound with the presentation of the food.
John Watson proposed that the process of classical conditioning (based on Pavlov’s observations) was able to explain all aspects of human psychology.
Everything from speech to emotional responses was simply patterns of stimulus and response. Watson denied completely the existence of the mind or consciousness. Watson believed that all individual differences in behavior were due to different experiences of learning. He famously said:

Answer:
Cas9-sgRNA cannot align with targeted DNA sequence
Explanation:
Without a PAM sequence, the CRISPR-sgRNA (small guide RNA) complex cannot align with the targeted DNA sequence. Therefore, you cannot perform experiments (e.g. gene editing) using CRISPR-Cas9.
Answer:
The fish appears nearer to the cat than it really is
Explanation:
The situation above is related to the refraction of light. The cat will think that the fish is closer to him, however, it is actually at a<u> different depth</u> in its<em> actual position</em>. This is because of the refraction of light as it travels in two different mediums: <em>water and air.</em> The eyes and brains are<u> not capable of tracing the light rays' refraction,</u> thus, the cat's image of the fish is on a shallower depth. In reality, the light rays reflecting from the fish are actually being refracted on the water's surface.
