Gynosperms is a plant that has seeds unprotected by an ovary or fruit and Gymnosperms include the conifers and cycads and angiosperms are a plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, and most trees.
Covalent bonds- are bonds that share electron pairs between atoms.
Ionic bonds are bonds that are made after one atom GIVES AWAY one or more electrons to the other atom.
Hydrogen Bonds- bonds between hydrogen(H) and usually O,N, or F. Hydrogen bonds are NOT TRUELY BONDS they are an ELECTROMAGNETIC ATTRACTIONS. These bonds can be Intramolecular(bonds within a molecule) or Intermolecular bonds (between two separate molecules). Individually a hydrogen bond is weak. However, hydrogen bonds can be strong in large numbers.
Metallic Bonding- occurs when metals bond with other metals their valence electrons become "delocalized," or free to move around. This delocalization forms something called the electron sea. In the electron sea, valence electrons DO NOT BELONG TO ANYONE ATOM.
Therefore, the answer is Covalent bonds.
Hope this helped! :)
Answer:
The metric system goes by powers of ten, so it's very easy to measure. That would be the main advantage, measurements of ten. We can also say it's the most used measurement around the world, so all scientists have little to no conversion, but the main answer is probably the first one :)
Answer:
Air Current
Explanation:
Say I am in California and there is a massive fire next to me but not close enough to me to really see the fire and the next day I see no fire but theres a ton of ash in the sky, this can be due to the wind current taking the smoke from the fire into my direction and that smoke falling in my area. So basically a wind current can take the smoke from a fire into another destination and cause a rapid change in air quality in a day.
