They don't offer justifications for why they are accurate. They are regarded as established facts.
- A theory essentially means the opposite. A well-supported explanation of a phenomenon in the natural world, including laws, hypotheses, and facts, is called a theory.
- A hypothesis is a statement about the natural world that can be verified by observations or tests. Hypotheses must be falsifiable—that is, they must be formulated in a fashion that allows them to be disproven—and be evaluated scientifically in order to be considered to be true.
- Scientific laws or laws of science are propositions that describe or forecast a variety of natural occurrences and are based on repeated tests or observations.
- Scientific rules condense the findings of tests or observations, typically within a specific applicability range. The accuracy of a law typically does not change when a new theory of the relevant phenomenon is developed; rather, the law's application area expands because the mathematics or statement that represents the law remains constant.
Therefore, scientific laws, theory, and hypothesis are different aspects of Science.

Answer:
Animals are adapted to the complex chain food since when they were no manufactured to the their food system. Without breakdown this complex food chain can not digest without breakdown.
Explanation:
Earthworm alimentary canal:
- Earthworm have a segmentation of well developed characteristics of all animals.
- The alimentary canal of earth worm as well as flatworm consists of buccal cavity, mouth, esophagus, crop, intestines', gizzard, and anus. The digestion occur extracellular that means the digestion occur outside the cells.
- Cockroach is an omnivores. It ranging from starchy to the sweet things to the paper and clothes etc. It suits its diet. Its alimentary canal consists of Foregut, midgut and the hindgut.
- Both are different in their structure as well as in their alimentary canal.
Answer:
The correct answer is polycistronic mRNA
Explanation:
There are two types of mRNA monocistronic and polycistronic. Monocistronic mRNA is the mRNA that codes for only one protein or polypeptide because it has single cistron. It is present in eukaryotes mainly.
A polycistronic mRNA has multiple cistron and codes for two or more proteins of polypeptides. Polycistronic mRNA is mainly found in prokaryotes. Prokaryotes have polycistronic mRNA because they are simpler than eukaryotes so only one promoter and operator is enough to translate multiple genes.
Answer:
The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.
Explanation:
You have to think of it as outside vs inside the cell.
Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration. Energy keeps the ions going from the way they would naturally happen.
