Mitosis...the organelles double in numbers in this stage. how?
the cell is in resting phase, preforming cell functions then the DNA replicates.
and after that, thats when the organelles double to prepare for division. :)
Energy (caloric) value of foods is indicated by calories, which measure the amount of heat that the food releases in the metabolic process. In physiology, it is determined by the energy balance of the organism, ie the heat exchange between the organism and the external environment.
Calories of nutrients:
1 g of protein = 4 kcal (kilocalories)
1 g of fat = 9 kcal
1 g of carbohydrates = 4 kcal
1 g of alcohol = 7 kcal
1 g of organic acid = 3 kcal
According to the table above, we can calculate required value:
29x4 + 6x4 + 1x9= 149 kcal/g
Muscle tension is determined by lots of factors including: (1) muscle force, depending on the amount of force that we exert into our muscles, the muscle tension also varies. (2) angle of pull. This is also a relevant aspect in determining the muscle contraction.
Answer: Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses. These grasses further modify the soil, which is then colonized by other types of plants. Each successive stage modifies the habitat by altering the amount of shade and the composition of the soil. The final stage of succession is a climax community, which is a very stable stage that can endure for hundreds of years.
