Which explains a difference between prokaryotic and eukaryotic gene reguation?

A.
Prokaryotes process DNA in the nucleus, so genes do not need to be activated.
B.
Eukaryotic gene regulation is controlled by more than one promoter and one regulator.
C.
Eukaryotes utilize operons, so they do not need to produce sections of mRNA.
D.
Prokaryotes do not have mRNA, so they do not have processes to degrade mRNA.

None of these statements is correct.

A. Eukaryotes utilize operons, so they do not need to produce sections of mRNA. This is not true, because prokaryotes utilize operons.

B. Prokaryotes process DNA in the nucleus, so genes do not need to be activated. This is not true because prokaryotes don’t have nucleus.

C. Eukaryotes express all genes, so gene expression does not need to be regulated. This is not true because eukaryotes express only certain genes, so, the regulation is high.

D. Prokaryotes do not have mRNA, so they do not have processes to degrade mRNA. This is not true because prokaryotes have mRNA.

Leslie argues that an organism called a Euglena is a plant because it is eukaryotic, has a nucleus, makes its own food, and is unicellular. Where is Leslie's error? Plants do not make their own food..

Explanation: with a great tolerance to a wide range of conditions the species would adapt and thrive which would allow it to reproduce and have all it needs to survive, grow, and take over.

Chromosome DNA Diploid EggGamete Haploid Meiosis Replication Sexual Reproduction Sperm..
This is an organism or cell with two sets of chromosomes.
This is a haploid cell with half the reproductive information from the parent.
This is a cell or organism having half of the diploid chromosome number, symbolized by "n".

Fungi are a food source for animals and humans. Fungi produce oxygen to breathe. Fungi destroy rocks and minerals. Fungi are natural recyclers.
