Answer:
A flower can either be classified as a monocot or a dicot depending on the number of petals present on the flower.
Explanation:
- Monocot also known as monocotyledon are characterized by the presence of one sees leaf(cotyledon) inside the embryo
The seed leaf is often thin because the endosperm which is required to feed the young plant is not found inside the seed leaf. In monocot flower a the number of petals is 3 or a multiple of 3. Examples of monocot flowers include; Asparagales, Wedges, Bromeliads, Poles.
- Dicots also known as dicotyledons are flowering plants that have two seed leaf. In a dicot flower the number of petals is 4 or 5 or a multiple of 4 or 5. Examples of dicot flowers include; Roses, Magnolas, Sunflower, Geranium.
The protons are pumped across the inner mitochondrial membrane from the inner matrix to the intermembrane space by the energy employed in the electron transport chain, creating a significant gradient in the hydrogen concentration. When it was discovered, this process was known as chemiosmosis.
<h3>The inner membrane is what?</h3>
The inner or cytoplasmic membrane controls the flow of nutrients, metabolites, macromolecules, and information into and out of the cytoplasm and preserves the proton motive force necessary for energy storage. It is impermeable to polar molecules.
<h3>What use does the intermembrane serve?</h3>
Proteins that are essential for mitochondrial energetics and apoptosis are found in the intermembrane region between the outer and inner membranes (process of programmed cell death). The inner membrane is significantly less permeable to ions and molecules than the outer membrane.

Answer:
The overall three-dimensional structure of a polypeptide is called its tertiary structure. The tertiary structure is primarily due to interactions between the R groups of the amino acids that make up the protein. ... These include hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridge formation.
Letter A is the answer.
