Answer:
lungs:
The blood first enters the right atrium.
The blood then flows through the tricuspid valve into the right ventricle.
When the heart beats, the ventricle pushes blood through the pulmonic valve into the pulmonary artery.
The pulmonary artery carries blood to the lungs where it “picks up” oxygen.
It then leaves the lungs to return to the heart through the pulmonary vein.
The blood enters the left atrium.
It drops through the mitral valve into the left ventricle.
The left ventricle then pumps blood through the aortic valve and into the aorta. The aorta is the artery that feeds the rest of the body through a system of blood vessels.
Blood returns to the heart from the body via two large blood vessels called the superior vena cava and the inferior vena cava. This blood carries little oxygen, as it is returning from the body where oxygen was used.
The vena cavas pump blood into the right atrium and the cycle begins all over again.
DNA replication is said to be semi-conservative because of this process of replication, where the resulting double helix is composed of both an old strand and a new strand. ... Semiconservative replication would produce two copies that each contained one of the original strands and one new strand.

<h2 /><h2>In situ hybridization</h2>
Explanation:
A)the cellular and tissue specific localization of the mRNA encoded by a particular gene
- In situ hybridization is a technique used to locate and detect nucleic acid sequences(DNA or RNA) with respect to their protein product within nuclei
- The principle behind in situ hybridization is that specific annealing(heat treatment process) of labelled probe to complementary sequences of target DNA or mRNA in a fixed specimen is done
- Probe is mainly used to find the complementary sequence of the nucleic acids(DNA or RNA) or helps in localization of particular clone
- The detection and visualization of the hybrids can be done by using cytological methods
