Answer:
Explanation:
In 1869, Friedrich Miescher isolated "nuclein," DNA with associated proteins, from cell nuclei. He was the first to identify DNA as a distinct molecule. Phoebus Levene was an organic chemist in the early 1900's. He is perhaps best known for his incorrect tetranucleotide hypothesis of DNA.
Answer:
Explanation:
surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action liquid molecules have at the interface.
The earth orbits the sun. Due to this fact, the northern and the southern hemisphere are tipped toward the sun at different times. Different climate zones fall under the southern and the northern hemisphere. There are many factors which affect the climate of a place and the most important one out of these factors is LATITUDE. Latitude refers to how far or close an area is to the north or the south of the equator. The latitude of a place determines the length and the intensity of sunlight that that place will experience. Thus, a place that is closer to the equator will continuously receive a lot of direct sunlight and such a place will have a warm climate.
You can reduce the levels of matter pollution by reducing the amount of particulate matter produced through smoke and by reducing vehicle emissions. Reduce the amount of particulate matter produced through any types of smoke.
