Definition: "The type of circulation pathway in which venous blood is passed
<span>from the right atrium of the heart through the right ventricle and
</span> pulmonary<span> arteries to the lungs where it is oxygenated and its return via the </span>pulmonary<span> veins to enter the left auricle and participate in the systemic </span>circulation"<span>.
Explanation:
There are two circulatory path in cardiovascular system namely pulmonary circulation and systemic circulation. Pulmonary circulation path allows for blood circulation through lungs for oxygenation while systemic circulation allows for transport of oxygenated blood to all parts of the body.
Pulmonary Circulation Pathway: Pulmonary circulation pathway consist of:
1. Superior and inferior vena cava:
De-oxygenated blood from lower parts of the body enter to right atrium through inferior vena cava. Similary, deoxygenated blood from upper parts of the body enter to right atrium through superior vena cava.
2. Right atrium and right ventricle:
From right atrium the blood passes to right ventricle through tricuspid valve.

3. Pulmonary artery: Afterwards, the blood enters the pulmonary artery via the pulmonary valve. The pulmonary artery divides into two arteries with one artery entering the right lung and the other artery entering the left lung. When the blood reaches the lungs through the left and right pulmonary arteries, it moves over alveoli via the capillary beds. </span><span>

4. Left atrium and left ventricle: After the blood gets oxygenated, it moves back to the heart and this time moves into the left atrium, completing the pulmonary circulation path.</span><span>

Helicases move along one strand of the duplex and push the opposing strand aside. They either migrate in the 3'-5' or 5'-3' orientation along the DNA or RNA (some can move in either direction).
- Living things need helicases, which are enzymes, to separate the double-stranded DNA in this instance from other nucleic acid strands.
- Helicases accomplish this by severing the hydrogen bonds that link the two strands.
- The DNA double helix's two strands are initially separated by an enzyme known as a DNA helicase.
- Each DnaB helicase winds the parental duplex by encircling one strand of the duplex DNA and moving in the 5′ to 3′ direction with respect to this ssDNA.
- Primers are created on occasion when DnaB interacts with primase.

For the answer to the question above, <span>Coyote behavior and social interactions vary greatly with season and geographic region. For the most part coyotes are diurnal or crepuscular (active at dawn and dusk), but have more nocturnal habits where they reside in close proximity to humans.
So the answer is A. </span><span>It is only active at dawn and dusk</span>
The nurse should advise both the mother and the husband to spend equal time to each twin as this will strengthen the parental bonds to both twins and discourage favoritism since that is a common scenario in parents with twins.
The mother should also be encouraged to breastfeed both twins.
