however non renewable resources are things like coal which can only be used once
Answer:protection from other predators.
Explanation: the quills will stick into a predator that attack the porcupine Note: it does NOT shoot its quills
Bacteria are single celled prokaryotic organisms. Prokaryotic means that they do not contain membrane-bound organelles. In simpler terms, they don't have cell parts within their cytoplasm. Bacteria are classified by their shape- round or cocci, rod or bacilli, and spiral or spirilla. Bacteria may also have long whip-like tails called flagella or be covered with small hair-like projections called cilia. Both structures are used for movement. Bacteria may have a cluster of free floating DNA in its cytoplasm called a nucleoid or they may have additional small rings of DNA called plasmids. Lastly, a bacterium have a cell wall made of a special compound called peptidoglycan which can provide an extra layer of protection from many environmental conditions.
Answer:
Most cells of adult mammals spend about 24 hours in interphase; this accounts for about 90%-96% of the total time involved in cell division. Interphase includes G1, S, and G2 phases. Mitosis and cytokinesis, however, are separate from interphase
Answer AND Explanation:
Exponential phase is the phase during which growth is rapid. The growth rate is proportional to the amount of material or number of cells of the organism already present. This rapid growth is due to:
- An increase in number of cells dividing following a geometric progression.
- Cells having adjusted to the new environment.
- Food and other factors are not limiting hence cells are not competing for resources.
- The rate of cell increase being higher than the rate of cell death.
