Plant cells have thick, sturdy cell walls, which provide rigidity and hold up the plant.
The correct option is this: BOTH MOVE MATERIALS DOWN A CONCENTRATION GRADIENT.
Active transport is a type of transport in the living cells in which energy is needed to move materials across a semi permeable membrane against a concentration gradient. Passive transport on the other hand is a type of transportation in cells, in which energy is not needed to move the materials across a biological membrane but the movement of the materials is against a concentration gradient.
If forest supplies are used up faster than they are replenished, wood products will become scarce.
Any wooden furniture such as beds, tables, and chairs will be hard to obtain. Pencils,books, and paper will also be limited because they are wood products l.
Answer: Telomeres, Helicases, Okazaki, DNA polymerase, Topoisomerase
Explanation:
1. Telomeres these are set of repetitive nucleotide sequence found at the end of a linear chromosomes they help preventing the DNA chromosome frrom sticking to other DNA chromosomes.
2. Helicases are proteins that uses energy (ATP) to unwind DNA strands during replication.
3. Okazaki fragments the small DNA nucleotide sequence synthesized separately on the lagging strand.
4. DNA polymerase are enzymes that catalyzes the addition of deoxyribonucleotides to DNA during replication.
5. Topoisomerase are enzymes that prevent single stranded DNA from supercoil, rumple and winding back during replication.
