molten material
magnetic stripes
Explanation:
The evidence that supports the proposition that sea floor spreading occurs from the options are the magnetic stripes and molten materials.
Harry Hess proposed the concept of sea floor spreading which further led to the development of the theory of plate tectonics.
Some of the evidences used are :
- Magnetic stripes in the rocks of the oceanic crust around spreading centers.
- They were discovered using magnetic survey of the ocean floor.
- Bands of magnetic minerals were seen to be oriented in particular direction and forms different patterns in the rock.
- Also, along spreading centers, molten materials rich in basalt abounds.
- This is because when sea floor begins to move apart, magma upwells from deep within the asthenosphere to replace them.

Answer:
Pulmonary artery
Explanation:
The pulmonary artery delivers oxygen poor blood to the lungs that comes from the right ventricle of the heart. The pulmonary artery is also the only artery in the body that carries unoxugenated blood. When the blood goes to the lungs, it picks up oxygen and drops off carbon dioxide to be expelled from the body. The pulmonary vein then takes the oxygen-rich blood and brings it back to the heart.
It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus
Cancer cells are insensitive to growth, they stimulate their own. They also resist inhibitory signals. They also deactivate cells and genes usually causing these opposing cells to die. <span />
