Answer:
<u>Hypothesis: If you eat Special K cereal for 2 weeks, you will lose 10 pounds.</u>
<u>Independent variable: Special K cereal.</u>
<u>Dependent Variable: Weight lose.</u>
Explanation:
<u>Hypothesis:</u> The term "hypothesis" is determined as a testable and a precise statement of what a specific researcher or experimenter predicts would be considers as the outcome of a particular study.
<u>Independent variable: </u>In research, the term "independent variable" is determined as a variable that is being re-organized in an experiment or research in order to see its impact on the dependent variable. Independent variable influences the dependent variable directly.
<u>Dependent variable: </u>The term "dependent variable" is determined as a variable that is being measured or tested in an experiment or research by the experimenter or researcher and is directly influenced by the independent variable.

chemical- new substance
physical- just a state change
Answer:
C. Fi 1:0, F2 3:1
Explanation:
Firstly, Mendel's law of segregation states that the alleles of a gene will randomly separate into gametes during gamete formation. In this case involving a single trait, hence, a single gene. Mendel crossed two purebreeding plants i.e. homozygous plants that produced different phenotypes for the same gene. He obtained his offsprings which he called F1 offsprings. He realized that all the F1 offsprings expressed only one phenotype. For example, when he crossed homozygous tall (TT) and short (tt) plants, he got F1 offsprings that were all tall.
He then self-crossed these F1 offsprings to produce a F2 offsprings that had a phenotypic ratio of 3:1 i.e. 3tall, 1short plant. He concluded that the alleles of the single gene had segregated into the gametes but one allele was capable of masking the expression of another, as seen in the heterozygous F1 offsprings that were all tall (Tt).
Hence, he obtained a 1:O ratio for his F1 offsprings then a 3:1 ratio for his F2 offsprings.
Answer:
omnivores
Explanation:
omnivores eat both plants and animals.
Length of PolyA tail is different in two cells
Explanation:
- Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
- PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
- It increases the stability of the molecule
- It protects the mRNA molecule from undergoing degradation in the cytoplasm
- It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
