Energy is always lost as energy is moved from one level to another. ... The loss of energy due to the second law of thermodynamics results in a pyramid with a large base and a 10% ratio between levels.
Answer:
The experiment wont work because both DNA and Protein contain nitrogen in their structure.
Explanation:
DNA and protein both contain nitrogen but phosphate group is present in DNA but absent in Protein.So when those 2 students tried to lebel the nitrogen of DNA it can be possible that nitrogen of protein molecule is being lebelled rather than the nitrogen of DNA.
As a result those 2 students do not found any trace of nitrogen of phage DNA inside the host Bacterium because the lebelled protein of the capsid remains outside the bacterium in form of ghost.
This suggests that a certain amount of body fat is necessary for menstrual cycles to occur. The nervous system appears to respond to circulating levels of the adipose tissue hormone leptin; when leptin levels fall below a certain set point, menstruation ceases. Because a woman lacking adequate fat reserves might not be able to have a successful pregnancy, the body prevents pregnancy by shutting down the ovarian cycle, and thus the menstrual cycle. Once sufficient energy reserves become available, the cycles begin again.
Answer:
Rainforest
Explanation:
Sunlight is a major limiting factor in the rainforest due to a very dense canopy created by taller trees and thus sunlight is blocked from reaching the rainforest floor making underbrush growth sparse. In rainforest, plant growth is confined to the surface due to limitations of light penetration as light intensity decreases with depth.
