Answer:
Salivating at the sight of food is an example of unconditioned response.
Evolution can also influence the acquisition of conditioned/learned response.
Animals learn to avoid eating things that are harmful or cause illness.
Monkeys can more easily be conditioned to fear snakes than to fear koalas.
Explanation:
- <u><em>Unconditioned stimuli</em></u>: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, food is an unconditioned stimulus.
- <u><em>Conditioned stimuli</em></u>: neutral, inoquos or biologically not significant stimuli.
- <u><em>Unconditioned Responses</em></u>: Unlearned response that is triggered by reflex because of an unconditioned stimulus. An example is salivating.
- <u><em>Conditioned Responses:</em></u> These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli.
Initially, an unconditioned stimulus does not provoke any response, but after enough exposition to conditioned and unconditioned stimuli together, the simple presence of unconditioned stimuli induces conditioned responses. In this aspect, the subject has learned to predict or to anticipate the unconditioned stimulus.
Animals also learn to avoid tastes that might cause them illness or might be harmful to them, and so they also learn to ignore visual or auditory sings that help them predict illness.
The detection of a harmful stimulus is an evolved predisposition rather than learned. Monkeys can show a detection advantage for a harmful animal such as the snake among non-harmful animals such as koalas. Indeed, snakes are an evolutionary threat stimuli in primates because most of them are poisonous.
Answer:
Recombinant DNA
Explanation:
Recombinant DNA (or rDNA) is made by combining DNA from two or more sources. In practice, the process often involves combining the DNA of different organisms.
Answer:
4900 J
Explanation:
Potential energy is the product of the mass, gravitational constant and the height of the object.
U=mgh=10 kg×9.8 m s^(-2)×50 m=4900 J
So, the potential energy of the object is 4900 J.
Answer:
The human body uses three types of molecules to yield the necessary energy to drive ATP synthesis: fats, proteins, and carbohydrates
The visibility is the given distance, condition and atomsphere
