Answer:
d. all endothelial cells would be venous
Explanation:
The Notch signaling pathway is a cell signaling system which consist basically of 4 NOTCH genes ( NOTCH1, NOTCH2, NOTCH3, and NOTCH4) each of them having the information to build a particular cell membrane receptor protein.
It has been demonstrated in zebrafish embryos that Notch signaling are highly determinant factors during vascular development, and a key function of these genes was specifically to regulate the differentiation of arterial fate in endothelial cells.
Notch signaling-deficient embryos showed a loss of expression of arterial markers such as ephrinB2 from arterial vessels with an accompanying expansion of venous markers into normally arterial domains. In contrast, embryos in which Notch signaling had been ectopically activated, meaning an activation out of "proper" place (where not expected, e.g. venous endothelial), exhibited the contrary phenotype, this is a suppression of vein-specific markers with ectopic expression of arterial markers in venous vessels.
To summarize, when Notch is supressed (in this case inhibited with a specific Notch inhibitor) arterial fate of endothelium is not followed, and venous fate is stablished. Thus, endothelial cells (those expected to form venous tissues but also arterial ones) would specified as venous.
The MRNA codon would be UCA
The DNA codon would be AGT
Upon researching, I believe the choices are:
<span>A. Chest radiograph and pulmonary function tests
B. Complete blood count with differential
C. Ophthalmologic examination
D. Renal function tests
E. Thyroid function tests
</span>
Among these, the baseline tests necessary for the patient before taking the medication are: A. Chest radiograph and pulmonary function tests, C. Ophthalmologic examination, and E. Thyroid function tests. This is because Amiodarone has several possible toxic side effects. Some of these are thyroid toxicity, opthalmic effects, and pulmonary toxicity. Thus, it is necessary to first know the baseline of the patient for these systems and then checking if the results have deviated much after he/she takes the medication.
For continued survival
animals gotta eat
Answer:
Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.
