I believe that if he added the Earth Worms, he could not mesure the time it takes to actually decompose the compost pile without the Earth Worms since it takes that long.

According to the principle of _______, a change in one species in a community results in a change in another.
Monica [59]

The correct answer is coevolution.

The term is used to illustrate the conditions where two or more species communally influence each other’s evolution. For example, an evolutionary modification in the morphology of a plant may influence the morphology of a herbivore that consumes it, this, in turn, may influence the evolution of the plant that might influence the evolution of the herbivore and so on.

Coevolution most possibly takes place when distinct species have a close ecological association with each other. These ecological associations include parasite/host and predator/prey, mutualistic species, and competitive species.

List what Eukaryotic cells and prokaryotic cells have.
wolverine [178]

Answer:

Summary

All cells have a plasma membrane, ribosomes, cytoplasm, and DNA.

Prokaryotic cells lack a nucleus and membrane-bound structures.

Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Explanation:

Eukaryotic Cells

Eukaryotic cells usually have multiple chromosomes, composed of DNA and protein. Some eukaryotic species have just a few chromosomes, others have close to 100 or more. These chromosomes are protected within the nucleus. In addition to a nucleus, eukaryotic cells include other membrane-bound structures called organelles. Organelles allow eukaryotic cells to be more specialized than prokaryotic cells. below are the organelles of eukaryotic cells , including the mitochondria, endoplasmic reticulum, and Golgi apparatus.

Prokaryotic cells are usually smaller and simpler than eukaryotic cells. They do not have a nucleus or other membrane-bound organelles. In prokaryotic cells, the DNA, or genetic material, forms a single large circle that coils up on itself. The DNA is located in the main part of the cell.

If one strand of a DNA molecule has the sequence of bases 5′-ATTGCA-3′, the mRNA synthesized following the template will be ____
rjkz [21]

If one strand of a DNA molecule has the sequence of bases 5-ATTGCA-3, the mRNA synthesized following the template will be 3-UAACGU-5.

Nucleotides are added to the growing strand one at a time in the precise sequence dictated by the existing  template strand. adenine and thymine are always paired with each other in the Watson-Crick DNA model, and cytosine is always paired with guanine.

The nucleotide sequence of DNA serves as a template for the nucleus, where mRNA is synthesised. The RNA polymerase II enzyme is responsible for this reaction's catalysis and needs nucleotide triphosphates as its substrates. Transcription is what happens in the nucleus when DNA is converted into mRNA. The cytoplasmic synthesis of proteins is controlled by the mRNA. The cytoplasm is where the mRNA that is produced in the nucleus attaches to the ribosomes after being transported from the nucleus. The nucleotide sequence of the mRNA serves as a guide for the assembly of proteins on ribosomes. The cytoplasm receives a "message" from the nucleus via mRNA. The nucleotide sequence of the mRNA, which is complementary to the nucleotide sequence of the messenger RNA, encodes the message.
