Answer:
Flowers
Explanation:
Angiosperms are plants that have flowers as their specialized reproductive organs. The flowers will give rise to seeds enclosed within an ovary.
The main reproductive parts are the stamen and pistil.
The stamen is the male part and it is made up of the anthers which produces pollen and the filament that holds the anthers in position.
The pistil on the other hand is the female reproductive part composed of ovary stigma and style.
The in the ovary is where the ovules are produced.

<span>Continental ice. You're looking at ice, which is freshwater, and there is a LOT more continental ice than sea ice</span>
The second option is the best answer.
Proteins are complex polymers of amino acids. They are folded into 3 dimensional structures . This folding defines not only the size and shape of the protein, but also its function.
The folding of a protein allows for interactions between amino acids that may be distant from each other in the primary sequence of the protein. In enzymes, some of these amino acids form a site in the structure that catalyzes the enzymatic reaction. This site is called the active site.
Answer:
Ball-and-stick models show the bonds between atoms, but not the relative sizes of the atoms. Space-filling models show the relative sizes of atoms, but not the bonds between atoms.
Explanation:
Chemically, it is hard to understand the complex structure and shapes of the atoms and molecules. For better understanding, scientists have different models that help show the molecules in different prospects. For example, ball-and-stick and space-filling models.
The ball-and-stick model shows the three-dimensional arrangement of atoms and bonds. This model has a limitation that the identification of atoms requires a key to color representations. This model also does not show the relative size of atoms.
The space-filling model shows a three-dimensional arrangement as well as the relative size between atoms. Bonding between atoms can sometimes be difficult to distinguish in this model.
