Answer:
Independent variable: CALCULATOR
dependent variable: SPEED AT SOLVING LONG DIVISION PROBLEMS
controlled variable: SAME GRADES, SAME PROBLEM
Explanation:
Independent variable is the variable that is changed or manipulated by the experimenter in an experiment. In this experiment, the independent variable is the CALCULATOR, which was changed in the experiment.
Dependent variable is the variable that is measured in the experiment. It is the variable that responds to changes made to the independent variable. In this experiment, the dependent variable is the SPEED AT SOLVING LONG DIVISION PROBLEMS.
Controlled variable or constants are variables that are kept unchanged for all groups throughout the experiment. In this experiment, the controlled variables are: SAME GRADES, SAME DIVISION PROBLEM
Answer:
Meiosis
Explanation:
Meiosis is the spliting of sex cells or chromosomes through the PMAT phase twice. <u>Mitosis</u> is the splitting of <u>body cells</u> such as skin cells ect. and only goes through PMAT once.
Impact the amount of carbon in the atmosphere, the biosphere, and the
hydrosphere
Explanation:
The processes of photosynthesis and cellular respiration play a major role in the carbon cycle.
Both these processes are interconnected where the products of a process become reactants of the other process.
Carbon dioxide and water released through cellular respiration become the reactants for photosynthesis which releases oxygen needed for cellular respiration.
The oxygen released is used by animals and human beings for respiration and releases carbon dioxide which is once again used by plants during photosynthesis. This gaseous exchange happening during these two processes helps to maintain atmospheric carbon dioxide levels stable.
In the biosphere, carbon is stored in the organic form in plants and trees. Plants absorb the external atmospheric carbon dioxide and convert it into organic form and store it as food by the process of photosynthesis.
In the hydrosphere, carbon is available as dissolved in water in the water bodies like ocean, rivers, etc. this carbon is absorbed by marine or aquatic plants to undergo photosynthesis and produce their own food. Again the organic carbon is formed and stored in the form of food which is used by other aquatic organisms.
Answer:
A single antibody gene can code for different related proteins, depending on the splicing that takes place post-transcriptionally.
Explanation:
According to the "one-gene, one-enzyme hypothesis", a gene code for single specific enzyme only. Beadle and Tatum proposed the one-gene, one-enzyme hypothesis that states that a gene encodes the genetic information for the synthesis of one enzyme only. However, alternative splicing in eukaryotes allows the formation of more than one related proteins/enzymes from a single gene.
For instance, alternative splicing of single primary transcript transcribed from an antibody gene allows the formation of multiple proteins. The primary transcript encoded by this gene has a segment of the gene that serves as either intron or exon. Depending on particular combinations of exons retained after splicing, multiple related proteins are formed by respective mRNA.
