Answer:
Photons
Explanation:
Photons are the only source of energy for photosynthesis. Photons are absorbed by chlorophyll molecules within Photosystems I and II (and antennae complexes), generating higher-energy ‘excited’ states of the photosystems which can carry out energetically costly chemical reactions.
The main purpose of seeds is to carry out reproduction so that the plants can perpetuate themselves. After pollination and Fertilization the seed formed has the capacity to germinate into an adult plant over time. It has all the necessary nutrients and food sources required for a plant to germinate and are also modified for different species to allow for further dispersal so the plant can spread more easily to better growth conditions.
Answer:
What is the heart rate of a black bear?
ICMs recorded an average of 25.0 ± 1.6 million heart beats/year for the bears (Range: 23.3 - 27.4 million beats/year). Activity sensors documented a minimum of 0 minutes (winter) to a maximum of 1084 minutes (summer) of activity over a 24 hour period.17 अग॰ 201
Claro que yo no sabo como Hacer eso
When insulin is deficient , GLUT4 transporters are not inserted into the cell membranes , glucose is not transported into the cells and the blood glucose concentration increases.
Insulin deficiency provides more amino acid and glycerol substrates for glucose synthesis ie increased gluconeogenesis .
With a deficiency of insulin, there is both increased hepatic glucose production through increased glycogenolysis and gluconeogenesis as well as decreased glucose use. The result is hyperglycemia.
