Between Neon and Calcium, neon will be more stable compared to the calcium.
Neon belongs to the group of elements on the periodic table called the noble gases. These are the most stable elements and they do not react with other elements.
- Calcium on the other hand is reactive
- It requires a loss of two electrons to attain stability.
- Therefore, it is a more reactive element.
Answer:
The experiment conducted in 1952 by hershey and chase consisted in the use of sulfur to track proteins and radioactive phosphorus to track DNA from T2 phages that infect bacterial cells, the key result was that phage proteins were outside the cell during the infection but the DNA was inside the cells because new phages were obtained with radioactive phosphorus. This allows us to conclude that DNA acts as a genetic material of phage T2
<span>The best example that represents the adhesion, cohesion, and surface tension of water is that water droplets forming a bead-like shape over a glass table. Cohesion: Water is pulled in to water. Adhesion: Water is pulled in to different substances. Adhesion and cohesion are water properties that influence each water particle on earth and furthermore the connection of water atoms with particles of different substances</span><span />
The right answer is B. controlling the flow of blood to the skin
When the body temperature is below the set point, the hypothalamus activates several thermogenesis mechanisms:
* Vasoconstriction on the vessels near th skin by the sympathetic nervous system to reduce thermal exchanges between the skin and the surrounding environment.
* And increase in heat production:
-by muscular activity:
-by the metabolism:
