I believe the Independent variable would be the temperature
Explanation:
Answer:
Explanation:
Transcription is the process by which a DNA nucleotide sequence is used as a template for the synthesis of an RNA molecule, which can be mRNA, tRNA or rRNA, by means of the enzyme RNA dependent DNA polymerase. Transcription in prokaryotes and eukaryotes differs in several respects, so they are studied separately.
1. The precursors of RNA synthesis are the four ribonucleotides 5 ’triphosphates (adenosine 5’-triphosphate, guanosine 5’-triphosphate, cytosine 5’-triphosphate and uridine 5’-triphosphate).
2. In the condensation reaction between the 5 'trisphosphate group of the incoming nucleotide and the 3'-OH group of the last nucleotide in the chain, the incoming nucleotide loses its two terminal phosphate groups. Its α group is used in the phosphodiester bond that binds it to the chain. This reaction occurs at the polymerase catalytic site.
Answer:
homeostasis
Explanation:
An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.
Basically, the endocrine system contributes significantly to the state of homeostasis in the body.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is simply because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
In conclusion, homeostasis is the term used to describe the maintenance of a constant internal environment or balance by living organisms such as humans and animals.
Answer:
Muscle and bones? They work to shoot an arrow.
Explanation:
B.False. The Earth's atmosphere helps with the greenhouse effect and without the greenhouse effect, the Earth would freeze over.
