NAD +molecule
Explanation:
Krebs cycle and electron transport chain are important steps in cellular respiration.
In the Krebs cycle, there is a need of NAD+ molecule which is then in Krebs cycle reduced to form a NADH2 molecule.
NADH2 is also an energy currency. It , giving electron in electron transport chain and return to Krebs cycle as NAD+.
Now in the Krebs cycle, it is ready to take electrons again.
Population density is the aspect of population ecology of the black-tailed prairie dog does this statement describe.
Explanation:
Population density is the number of organisms are there in per unit area. It is used to measure geographical area occupied by organisms and its statistics.
In population ecology the structure, dynamics and contribution of population of species is studied. The idea of species distribution is studied in it.
The population density determines the number of species or members of particular population are present is a particular area.
An area of low density population will have more resources and more area per organism and less competition for resources and vice versa for high density population.
Prairie dogs have 12 adults per hectare of area this tells the population density of the rodents.
The correct answer is A) A roast at 125°F (52°C)
Explanation:
In general terms, bacteria thrive at warm temperatures; this means bacterial growth is lower at extremely hot/cold temperatures, but it is higher at warm or medium temperatures. Indeed, the ideal temperature for bacteria to develop and reproduce is between 4° C and 60°C. This implies from the options given the roast at 52°C represents an ideal temperature for the growth of bacteria. Also, other options include temperatures above 60°C, and therefore do not allow bacteria to grow well.
The answer is called the Medulla oblongata. Please help me now as saying this is the brainiest answer, thanks.
