Answer:
Carbon and Its Compounds: Ethane, carbohydrates, diamond
Oxygen and Its Compounds: Ozone, water
Explanation:
Carbon and its compounds refers to compounds that has carbon atoms in them whether they exist in nature or are made artificially. Examples include
- Ethane, C2H6
- Carbohydrates, Cx(H2O)y
- Diamond, an allotrope of carbon
Oxygen and its compounds refers to compounds that has at least an oxygen atom in them whether they exist in nature or are made artificially. Examples include:
- Ozone, O3 an allotrope of oxygen found in the upper part of the atmosphere
- water, H2O
Answer:
the process in which energy is emitted by one object, transmitted through space, and absorbed by another is correct.
Explanation:
The transfer of energy is not by movement.
Answer:
Humans are multicellular, complex organisms. The cells inside our bodies are “specialized.” This means that each type of cell performs a unique and special function. For this reason, each of the 200 different types of cells in the body has a different structure, size, shape, and function, and contains different organelles.
For example:
Cells in the brain may be longer in shape so they can transmit signals more efficiently.
Cells of the heart have more mitochondria because they need a lot of energy.
Cells in the respiratory system are responsible for taking up oxygen and releasing carbon dioxide.
All the cells work together to keep the human body running efficiently.
Answer:
GTP-bound form
Explanation:
Such a receptor may be associated with the GDP-regulated G-stimulant protein system. When the neurotransmitter binds to the receptor, the protein G-GDP complex is activated by separating its β subunit. When the ligand "sticks" to it, it releases GDP and allows GTP to bind. This form of the G protein that binds GTP, is the activated ("on") form of it. When it is "on" it releases signals into the cell. After a short period (seconds or less) the G protein hydrolyzes the GTP to GDP and itself "turns off".
