Systematic error affects the
measurement in a constant way and represents stable factors that affect the
observed score in the same way each time the measurement is made. Systematic
error is a steady, repeatable error joined with faulty measuring equipment or an
imperfect experiment design.

Question: In prokaryotes, genes can exist as operons that are transcribed into a polycistronic mRNA, containing multiple genes in a single transcript. In eukaryotes, transcripts exist only as monocistronic mRNA containing a single gene. What fundamental genetic difference is responsible for this distinction?
(A) mRNA is transported outside of the nucleus in eukaryotes.
(B) Prokaryotic mRNA has a five-prime GTP cap.
(C) Prokaryotes use a single start codon for multiple genes.
(D) In eukaryotes, each gene has its own transcription initiation site
Answer:
(D) In eukaryotes, each gene has its own transcription initiation site
Explanation:
Eukaryotic mRNAs are monocistronic in nature which means that one mRNA carries the single transcript to be encoded. Each monocistronic mRNA is encoded by a stretch of a gene that has a specific initiation site to start the process of transcription. On the other hand, prokaryotes have some mRNAs that carry the code for two or more different polypeptides. These mRNAs are called polycistronic. For a polycistronic mRNA, multiple transcripts are transcribed under the single transcription initiation site.
Answer:Animals who live in the tundra have special adaptations to survive. ... The food chain in the Arctic Tundra consists of predators such as owls, foxes, wolves, and polar bears at the top of the chain. Predators hunt herbivores, plant eating animals, such as caribou, lemmings, and hares.Animals found in the Arctic tundra include herbivorous mammals (lemmings, voles, caribou, arctic hares, and squirrels), carnivorous mammals (arctic foxes, wolves, and polar bears), fish (cod, flatfish, salmon, and trout), insects (mosquitoes, flies, moths, grasshoppers, and black flies), and birds (ravens, snow buntings ...

The following compounds can be classified as lipids: steroids, saturated fatty acids, phospholipids, unsaturated fatty acids.
WHAT ARE LIPIDS:
- Lipids are one of the four biomolecules in nature; the other three being proteins, nucleic acids and carbohydrates.
- Lipids are composed of long chains of carbon, hydrogen and oxygen. They are insoluble in water.
- Lipids consists of sterols, phospholipids, fats, triglycerides, unsaturated and saturated fats etc.
Therefore, the following compounds can be classified as lipids: steroids, saturated fatty acids, phospholipids, unsaturated fatty acids
