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:
Answer:
c. Two sister chromatids did not separate into the proper daughter cells during anaphase.
Explanation:
The observed cell is undergoing mitosis which does not include separation of homologous chromosomes. During anaphase of mitosis, two sister chromatids of each chromosome separate from each other. They move to opposite poles. This results in equal distribution of two complete sets of chromosomes to each daughter cell.
However, the failure of two sister chromatids of a chromosome during anaphase would lead to the formation of two abnormal daughter cells. One of the daughter cells would have one extra chromosome (2n+1) while the other would lack one chromosome from the diploid set (2n-1).
Answer:
I am pretty sure the answer is Melting
Explanation:
Tight junctions are cell junctions that seal tissues. These junctions form protective and functional barriers.
- The cell junction that is involved in creating a barrier between cells is the TIGHT junction.
- The tight junctions are cell-cell adhesion structures implicated in cell polarity and signaling.
- On the other hand, adherens junctions are cell junctions required for maintaining contact inhibition.
- Finally, desmosomes are intercellular junctions that bind intermediate filaments of the cytoskeleton with cadherin proteins.

A producer cannot make sugars in the absence of light, the correct option is A.
<h3>What are producers?</h3>
Producers, also known as autotrophs, are lifeforms that produce their own food.
They obtain energy from chemicals or the sun and transform it into usable energy in the form of sugar or food using water.
Plants and algae can produce their own food by harnessing solar energy. These organisms are referred to as producers because they generate their own food.
Thus, the correct option is A.
