Answer:
Write the amount similar dominant and different squares as one phenotypic group. Count the amount of similar recessive squares as another group. Write the result as a ratio of the two groups. A count of 3 from one group and 1 from the other would give a ratio of 3:1.
Explanation:
hope this helps and why you said thx
For question number 1, there is one phenotype only with homozygous allele which are recessive and dominant of both parents. For question number 2, the answer is letter B. plants with both red and blue flowers because it is codominant so the trait will express both alleles. For question number 3, the answer is letter C. four genetically identical cells because it is from two daughter cells which undergo meiosis that results into 4 identical cells that are needed for somatic cells in our body. For question number 4, the answer is the leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5 because it is based in the ends of each nucleotides that is carrying the genes. For question number 5, the answer is gene regulation which is used by cells to increase of decrease specific gene products or RNA.
Answer:
It decreases the levels of cAMP in the cell, repressing transcription from the lac operon.
Explanation:
When glucose is absent, cAMP serves as coactivator binds to CRP, the catabolite gene activator protein. The CRP-cAMP complex binds to the site near the lac promoter and stimulates the expression of the operon by RNA polymerase many folds.
Catabolite repression refers to inhibition of the synthesis of enzymes of lactose catabolism when glucose is present as an energy source. In the presence of glucose, synthesis of cAMP is inhibited resulting in its lower cellular concentration. The lower cAMP levels do not allow the binding of cAMP and CRP. The result is reduced expressed of lac operon.
Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
Answer:
okay so just act out the character when you write it down what exactly are they asking you to do the directions aren't even clear. I do not like what these teachers give out these
