Answer:
Yes.
Explanation:
Yes, a new research indicates that dogs might use a magnetic sense to navigate. Dogs has world class nose which helps them to navigate to their destination but it also has a magnetic compass that helps them in navigation. The dogs use magnetic field of the earth to find out shortcut ways in the unknown land or terrain so the hypothesis is right that dogs used magnetic sense for navigation.
<span>Organic Chemistry is so important in the study of Biology because most reactions in Biology are organic reactions. Organic chemistry is the study of structure, properties, and reactions of organic compounds</span>
Answer:6
Explanation:
Total number of chromosome in a cell is the total number of haploid chromosome which when calculated gives 6
Answer:
Uses of genetic engineering include:
increasing plant food production
improving medical treatment
Explanation:
Genetic engineering can be described as a technique in which the genome of an organism is manipulated for the benefit of humankind. The processes of genetic engineering involved the manipulation of the plants and animals DNA so that they will be able to produce more better characteristics. Also, drugs such as vaccines can be produced in animals by the techniques of genetic engineering.
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.
