Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
Answer:
Desmosomes
Explanation:
Desmosomes are cellular structures that adhere to neighboring cells. Its function is to hold the epithelial cells together, associating the intermediate filament cytoskeletons of neighboring cells, thus forming a transcellular network with high resistance to mechanical traction. It thus allows the cells to maintain their shape and the epithelial sheet to exist in a stable form. Inside cells act as anchoring sites for intermediate rope-shaped filaments, which form a structural network in the cytoplasm providing a certain rigidity. Through these junctions the intermediate filaments of the adjacent cells are indirectly connected forming a continuous network that extends throughout the tissue.
Answer: start seeds as early as mid-January
1 to 1 1/2 inches of water each week
Use as much sunlight as you possibly can
Mulch and prune them
explanation:
Receptors within the highlighted area provide the sense of HEARING.
The highlighted section of the ear is the organ of Corti. The organ of corti is the sensory receptor inside the cochlea, which holds the hair cells, which are the nerve receptors for hearing.
Answer:
Explanation:
1. What are negative effects of technology?
You're losing sleep or skipping physical activities due to technology use. It's causing you stress or anxiety, or you're noticing physical side effects, such as tension headaches, eye strain, muscle pain, or overuse injuries.
Positives:
Technology, which brings together tools to promote development, use and information exchange, has as its main objective of making tasks easier and the solving of many problems of mankind. When technology progresses and makes our lives even more convenient, we must stress how beneficial it is to our lives
2. Don't know
3. Decision Matrix Method. Decision matrix techniques are used to define attributes, weigh them, and appropriately sum the weighted attributes to give a relative ranking among design alternatives.
