Answer: protists are eukaryotes, while bacteria are prokaryotes.
Bacteria are single-celled microbes, which means they are prokaryotes because they lack organelles.
Protists are single-celled eukaryotic organisms that aren't plants, fungi, and animals.
Even though both organelles are found in eukaryotic cells<span>, both </span>mitochondria and chloroplast<span> have characteristics often found in </span>prokaryotic cells<span>. These </span>prokaryotic cell<span> characteristics include: an enclosed double membrane, circular DNA, and bacteria-</span>like<span> ribosomes.</span>
Prophase, metaphase, anophase, telophase.
Answer:
The answer is A.
Explanation:
During logarithmic growth phase bacteria grows exponentially doubling every x minutes (x depends on the species). In this question doubling time/generation time is every 15 minutes and log phase takes 5 hours, which equals to the 300 minutes. During 300 minutes bacteria doubles 20 times (300/15 = 20) which equals 2^20. Bacteria culture has been started with 1000 bacterial cells so it must be added to the calculation therefore right answer is: 1000 X 2^20.
