The primary and most significant greenhouse gas emitted from human activities is carbon dioxide. Burning of fossil fuels is the major cause of increased carbon dioxide emission.The burning of coal, oil, and natural gas is an important energy source to produce electricity.
The 7 (sometimes 8) characteristics of life are:
1. living things are composed of cells
2. living things have different levels of organization
3. living things metabolize (i.e. use energy)
4. living things respond to their environment
5. living things grow
6. living things reproduce
7. living things adapt to their environment
(some sources include) 8. living things have genetic material
Viruses do not metabolize, they do not grow, they do not adapt to their environment, and they cannot reproduce independently; viruses require host cells to reproduce and perform the other functions that give them the appearance of aliveness.
Answer:
Independent variable: ALTITUDE
dependent variable: GROWTH OF PLANTS
Confounding variable: STOREYS OF THE BUILDING
Explanation:
In an experiment, the basic components i.e primary variables that an experiment should contain, are the independent and dependent variables.
- The independent variable is the variable that is changed or manipulated in an experiment. In this experiment, the ALTITUDE of the plant is the independent variable.
- The dependent variable is the variable that responds to changes to the independent variable. It is the variable measured in an experiment. In this case, the dependent variable is the GROWTH OF THE PLANTS.
- The confounding variable is a variable that has an extra influence on the outcome of the experiment. In other words, the confounding variable has an impact on the dependent variable. In this case, the confounding variable is the STOREYS OF THE BUILDING.
Answer: Neurotransmission
Explanation:
The transfer of the information from one neuron to another takes place through the release of the chemical substances from the axon of one neuron to the dendrite of another via synaptic junction.
The chemicals that is transferred between two neurons is known as neurotransmitter and the process is known as neurotransmission.
The brain consists of multiple neurons and this is how the information is transferred across the brain and body.
