Answer:

Telomeres cap and protect the ends of chromosomes from degradation and illegitimate recombination. ... Abolition of telomerase activity in such cells nevertheless results in telomere shortening, a process that eventually destabilizes the ends of chromosomes, leading to genomic instability and cell growth arrest or death.

They protect the ends of our chromosomes by forming a cap, much like the plastic tip on shoelaces. If the telomeres were not there, our chromosomes may end up sticking to other chromosomes.

What does this animation mean when it says that ATP is like a rechargeable battery?
Solnce55 [7]

I dont know what animation you mean about but i will give my opinion.

ATP are used for energy, they are made inside mitochondria. Mitochondria use oxygen and food to make ATP, which is maybe what u mean by rechargable is because whenever you eat, the mitochondria will produce energy again and again.

What is the endosymbiotic hypothesis?
stepan [7]

Answer: What does the endosymbiont hypothesis propose? It proposes that early eukaryotic cells acquired the precursors of mitochondria and chloroplasts by engulfing certain types of bacteria. ... Mitochondria, chloroplasts, and centrioles in eukaryotic cells each contain their own minute and unique supply of DNA.

Explanation:

The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.

can someone explain to me what a Eukaryote and a prokaryote is and why they are different? i keep confusing them.
monitta
An eukaryote is a cell that has organelles like the mitochondria, nucleous, etc.. A prokaryote is a cell with no organelles, meaning that the dna flows freely in it. A way i remember which is which, is that the "pro" in prokaryote rhymes with "no" which means "no organelles"
