Endosymbiosis
that is my explanation hopefully its right
The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. As the altitude increases the number of air molecules decreases, the average of their kinetic energy decreases.
Does this help?
if it does please mark me brainliest! thanks:)
I think the answer is D but it's been a while since I've done this.
1. Chromosome condense (Prophase)
2. Spindle fibers form (Prophase)
3. Chromosomes allign in the center of the cell (Metaphase)
4. Chromosomes separate (Anaphase)
5. Cell membrane pinches (Telophase and Cytokenesis)
6. Spindle fibers disappear (Conclusion of Cytokenesis)
The correct answer is a - Lipid
Lipids are not considered as macromolecules because unlike proteins, carbohydrates and nucleic acids which polymers, lipids are composed of a single unit made up a glycerol backbone to which two or three fatty acids are linked.
Lipids are not polymers made up of individual subunits called monomers. They contain only one molecule and are not macromolecuels.
Examples of lipids include waxes, steroids, phospholipids and detergents. Lipids are generally hydrophobic and insoluble in water.
