Answer:
Humans get there energy primarily from glucose I believe. We break down glucose to get ATP (Adenosine Triphosphate) which is then used to supply energy to our cells in order to function.
Explanation:
Answer:
They are effective for long periods of time
Explanation:
Alpha and Beta interferons are part or form of Interferons. The Alpha interferons is derived from leukocytes infected with virus, while the Beta is derived from fibroblasts infected with virus.
Both of them have various mechanism of action including:
1. they bind to the surface of uninfected cells.
2. they initiate manufacture of antiviral proteins.
3. they disrupt stages of viral multiplication.
4. they initiate transcription.
Hence, in this case, the correct answer is "they are effective for long periods" because they are not.
oxygen is the correct answer
Answer:
- Unconditioned stimuli, US: getting hurt by hot water.
- Conditioned stimulus, CS: hearing a toilet flush.
- Unconditioned response, UR: feeling pain after hurting.
- Conditioned response, CR: being afraid when hearing a toilet flush.
Explanation:
- Unconditioned stimuli: Biologically significant stimuli that provoke an unlearned or reflex reaction. For example, getting hurt by hot water.
- Conditioned stimuli: neutral, innocuous or biologically not significant stimuli. For example, hearing a toilet flush.
- Unconditioned Responses: Unlearned response that is triggered by reflex because of an unconditioned stimulus. For example, feeling a lot of pain after hurting by hot water.
- Conditioned Responses: These are provoked by conditioned stimuli. This refers to a learned response that reflects the association between conditioned and unconditioned stimuli. For example, being afraid when hearing a toilet flush.
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.
Answer:
enhancer sequences bind to transcription factors to increase the likelihood of transcription
Explanation:
Enhancers are short DNA regions (50–1000 bp) that may be localized upstream and downstream from the transcription start sites of the gene. It has been shown that enhancers can be localized several kilobases (30-100 kb) either 5' or 3' of the gene. These sequences bind to proteins (generally transcription factors) in order to alter the 3D structure of the DNA, thereby increasing the likelihood of transcription.
