Answer:
All the organisms of one kind in an ecosystem are called a population. For example, a pond ecosystem might have populations of frogs, waterlilies, insects, duckweed, and protists. Populations living and interacting with each other form a community.
Explanation:
Answer:
Replication - Transcription - Translation
Explanation:
Replication duplicates the DNA so that happens first. Then in transcription converts the DNA to mRNA which goes to the cytoplasm to make proteins. In translation proteins are made when codons and anti codons join to make amino acids which create the proteins.
The ecosystem is everything that exists in a particular environment.
Answer:
The correct answer is: a. A single mRNA can be translated simultaneously by several ribosomes.
Explanation:
Ribosomes are structures composed of ribosomal RNA (rRNA) that direct the process of translation, with the help of special proteins and key molecules called transfer RNA (tRNA) that are 'able to read' the codons in the mRNA. To help with this 'reading', ribosomes move through the mRNA strand as the translation moves forward, placing the anticodons presented by the tRNA molecules with their specific match - each mRNA codon - forming a strand of amino acids.
To ease the process in the cases where the molecule to be translated is a polypeptide, groups of ribosomes form a <u>polysome </u>and they all translate one single mRNA strand at the same time. Each of these ribosomes starts translating from the first codon and stop when the stop codon appears.
Answer:
The Citric Acid cycle and Electron Transport chain processes are part of a set of steps that occurs in cellular respiration.
During cellular respiration, a glucose molecule is gradually decomposed into carbon dioxide and water. Along the way, some ATPs are produced directly in the reactions that transform glucose. However, much later ATP is produced in a process called oxidative phosphorylation. Oxidative phosphorylation is fueled by the movement of electrons through the electron transport chain, a series of proteins incorporated into the inner membrane of mitochondria. Thus, Citric Acid cycle is responsible for degrading the acetyl CoA produced by previous reactions (glycolysis and pyruvate oxidation) producing four more carbon dioxide molecules, plus energized electrons and H + ions, which will be captured by NAD + and another acceptor. of electrons and hydrogen called FAD (Flavine Adenine Dinucleotide), originating NADH and FADH2 molecules. During this process, two GTP (Guanosine triphosphate - very similar to ATP) molecules are also formed. After this process, through the electron transport chain reaction NAD and FADH2 produced in the other steps deposit their electrons in the electron transport chain returning to the "pure" form (NAD + and FADH2). As electrons travel down the chain, energy is released that is used to pump protons out of the matrix, forming a gradient. Protons return to the matrix by means of an enzyme called ATP synthase, producing ATP. At the end of the electron transport chain, oxygen receives electrons and acquires protons to form water.
