In a water molecule (H2O), the oxygen nucleus with +8 charges attracts electrons better than the hydrogen nucleus with its +1 charge. ... The hydrogen atoms are not only covalently attached to their oxygen atoms but also attracted towards other nearby oxygen atoms. This attraction is the basis of the 'hydrogen' bonds.
The answer is 3 heat and or presssure is applied
Bruh what the heck does this even mean
Answer:
Cells from the pure culture can cause disease in healthy individual after infecting it with the pure culture.
Explanation:
Koch postulates says that microbes are the cause of every disease. These microbes can be isolated from the infected host and can be grown outside the host in a pure culture. Then this pure culture is able to cause disease in a healthy host after infecting the host with pure culture. Then this same microbe can again be isolated from the second host.
So Koch postulates which proves that cells from the pure culture can cause disease in healthy individuals after infecting it with the pure culture was the step that enabled Koch to determine that a particular microbe is the cause of the disease because it was causing disease in healthy individual also.
Answer:
240 kilograms
Explanation:
The productivity is the rate at which energy is added to the bodies of organisms in the form of biomass (amount of matter in the body).
The total biomass in the body of a heterotroph = 1560 kilograms
Biomass used in the respiration = 900 kilograms
Egested matter = 420 kilograms
Net secondary production = 1560 - 900 - 420
Net secondary production = 240 kilograms
