Zero population growth rate is virtually impossible because, to achieve it the birth and death rates have to be exactly the same. However the growth rate can be close to zero over a long period of time. The age structure diagram is affected by the birth and death rates of a population. Also the relative proportion of males and females in the population shapes it. The mortality rates at different cohorts affect the abundance of population in that cohort.

Oldham Pond
For the organisms in the pond, Ad Libitum sampling was used, where much information about the organisms was measured (John & Eugene 106).According to the results, the temperature of the water was comparable to that of the surrounding air. The slight difference is the difference in conductivity of heat by air and water. Dissolved oxygen levels were also concurrent to those that are recommendable (11 mg/l). Conductivity, however, was found to be higher than recommended. Recommended conductivity

Measles and the two vaccination shots given to ensure the child will never catch Measles
In turn, the activated helper T cells initiate the release of interleukins (IL), particularly IL-2, which initiates antigen-specific T-cell growth and activates cytotoxic T cells, IL-4, which promotes growth of B cells, and IL-5, which allows activation of B-cells. IL-4 and IL-5 also induce the transformation of IgM to IgG, IgA and IgE. In effect, it stimulates clonal expansion of both T and B cells after exposure with specific antigens. Cytotoxic T cells, in particular, are enabled to kill

Helper T cells secrete cytokines. Cytokines provide amplification mechanism by proliferation and differentiation (stimulation of B cell clonal expansion). They also determine the type of antibodies produced (Sridhar, 2012).Human immunodeficiency virus (HIV) attacks a protein, CD4, on helper T cells of the immune system and associates with it. These cells are the immune system’s main infection fighting cells. T helper cells are necessary for activation of B-cells and cytotoxic T-cell immune

Which opens the taste receptors on coming in contact with a particular food chemical while sodium channels in the inner ear hair cells are mechanically-gated that are disturbed by sound vibrations. In either case the right stimulus leads to the opening of sodium channel, leading the flow of sodium ions into the cell, causing membrane potential depolarization and ultimately influences the voltage-gated channels of sodium located nearby and initiates an action potential.Neurons receive and send

Discuss how the molecular clock hypothesis (gene clock, evolutionary clock, or molecular clock) can be used to explain the divergence of species
This means that evolutionary biologists can take advantage of this data to conclude the method through which species evolve, and to construe the time when two species diverged, particularly with regard to the evolutionary timeline. The molecular clock is comparable to a normal wristwatch so as to appreciate how the molecular clock works in providing information on the divergence of species. Notably, while a wristwatch measures time from ticks, which are essentially regular changes in time
