Answer: High flow O2 is best. It is used with those persons who present with severe cluster headache or migraine; the triptan is contraindicated by her B.P., Ibuprofen would not be very useful with presentation of aura and bilateral nature of her headache; ergotamine is surely contraindicated given her history.
Explanation:
When grilling chicken using charcoal fire, the energy transformation that takes place starts from chemical energy, to radiant energy and then thermal energy. The combustion reaction of the charcoal fire converts the chemical energy into heat. The charcoal fire is considered as radiant energy. Lastly, burning fuels like coal or wood produces thermal energy, and that thermal energy is basically the reason why the chicken was cooked even without directly touching the fire.
Answer:
40 individuals
Explanation:
The homozygous recessive percentage is equal to q2.
Recessive genotype frequency, q 2 is 1/1000000 = 0.000001
therefore, q = 
= 
= 0.001 = allele "a" frequency
and p + q = 1, thus, p = 1 – q = 1 – 0.001 = 0.999
thus, the frequency of allele a = q = 0.001 and the frequency of allele A = p = 0.999
Carriers are heterozygous and are equal to 2pq.
So, 2pq = 2 x 0.999 x 0.001 x 20,000 = 39.96 (round of to 40)
Hence, 40 individuals will be expected to carry the recessive allele.
The terms that complete the sentence 'The __________ and __________ are the glands that stimulate reproductive cycles' are b. testes . . . ovaries. Testes are male gonads and ovaries are female gonads in animals. These organs are glands that are involved in reproductive cycles. They produce gametes which take place in reproduction, but they also produce hormones that stimulate reproductive cycles.

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.
