B temperature and precipitation
1 ) The first terrarium was developed by botanist Nathaniel Bagshaw Ward in 1842. He was interested in studying insect behaviour. Once he accidentally left one of his bug jars open. A fern spore in the jar sprouted, grew and germinated into a new plant. This is how the first terrarium had been created.
2 ) <span />Because of the different conditions within, terrariums there are two, which can be classified as closed and open. Closed terrariums have a lid to enclose the plants entirely within the glass container. Open terrariums do not require a lid.
Sorry working on this right now as well, and I don't have the others yet :(

An omega-3 fatty acid is one that has its first double bond at the <u>methyl </u>end of the molecule.
Explanation:
Fatty acids will have a methyl end and a carboxylic acid end and the long carbon chain.
The number of hydrogen atoms attached to the carbon atoms depends upon its saturation type – saturated or unsaturated fatty acid.
The main advantage of the unsaturated fatty acids is that they have fewer hydrogen atoms because they are replaced with a double bond between the carbon atoms.
There are both short chain (carbon atoms 18 or less) or long chain (more than 20) fatty acids.
Omega-3 fatty acids are polyunsaturated fatty acids (PUFA). Depending upon the carbon chain length, the first C=C double bond occurs between the third and fourth carbon atom from its methyl end on the carbon chain of the omega-3 fatty acid.
Omega-3 fatty acids are recommended by dieticians due to its immense health benefits especially for the heart since it reduces blood triglyceride level, blood pressure, plaque formation, and the risk factors for heart attacks or failure. These are also good for the eyes, to treat mental depression, and for fetal brain development during pregnancy.
Answer:
• covers the body and makes up inner lining
• protects against damage, dust, bacteria
Explanation:
They converted carbon dioxide to oxygen. The increased oxygen levels allowed for cellular respiration to occur instead of only glycolysis. The atmosphere became thinner, decreasing temperatures of the planet as well.
