Answer:
B. The mutation results in a new, dominant allele
C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.
D. The mutation occurs in a codon and alters the function of the final protein
Explanation:
All the above things will change the <u>ultimate expression</u> or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.
Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.
This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.
Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.
Answer: "homeostatic (dynamic equilibrium) range"
Homeostasis can be observed through the "homeostatic range (pre-set limits)" of the body's pH, temperature and blood glucose.
Explanation:
Homeostasis is the control of internal environment , physical and chemical conditions maintained by the living systems. A body takes control of its internal environment in spite of external forces interruptions. It can be defined as the body's defensive mechanisms.
Homeostasis is maintained and controlled by the nervous system.
Homeostasis is for optimal functioning of the internal environment such as body pH, body temperature, fluid balance, chemical ions balance (calcium, sodium and potassium) and blood glucose.
Body temperature is normally about 37.5° C (98.6° F).
Salt concentration in body fluids is normally about 0.9%
Blood glucose is normally about 10 mg/ml.
A disturbed (imbalanced body as a result of external forces) body regains its haemostasis balance by
Activating reflexes that fight the disturbance and maintaining behaviours to counteract the disturbance.
Answer:
The statement that will show the best accurate criteria is patient's respiratory rate is 16 breaths/minute and blood pressure is 130/72 mm Hg.
Explanation:
Adrenergic drugs are drugs that cause the stimulation of the sympathetic nervous system, which is also known as adrenergic nervous system by performing or mimicking the activities of the epinephrine and norepinephrine, or interfering with their release.
It should be noted that, epinephrine and norepinephrine are also known as adrenaline and noradrenaline, this is because they are secreted by the adrenal gland, and this gives rise to the term adrenergic.
Examples of adrenergic drugs are phenylephrine, clonidine and oxymetazolin among others.
