Experimental advantages of using pea plants included which of the following?
- They came in several varieties.
- They were capable of self-fertilization.
- They were easy to cross.
- Their anthers could be removed prior to pollination.
- All of the above were advantages.

Introduction:
Gregor Mendel has chosen pea plants for experiments because they are easily grown, have many offspring per mating, could fertilize themselves and have easily observable varieties of genotype and phenotype.
Answer to Problem 1TY
The correct answer is option (e) all of the above.
Explanation of Solution
Explanation/justification for the correct answer:
Option (e) all of the above. Peas are found in many varieties that vary in features such as seed size, seeds, flowers, and stems. A female gamete of the same plant is fertilized by a male gamete; this is called self-fertilization. The female and male sex organs are present in the single flower (same flower) of peas. Garden peas are ease of making crosses. The process is known as hybridization when two individuals of the same species are crossed or bred to each other with different characteristics and the offspring are refers to as hybrids. The anther can be removed so that the flower could not self-fertilize and the pollen can be transfer to another flower of a different plant. So, the correct answer is option (e).
Explanation for incorrect answer:
Option (a) They came in several varieties. Peas are present in several varieties that differ in features such as the appearance of seeds, flowers, pods, and stems. Thus, this is not only the correct option. So, this is an incorrect option.
Option (b) They were capable of self-fertilization. In a pea plant, a female gamete is fertilized by a male gamete which is said as self-fertilization. Thus, this is not only the correct option. So, this is an incorrect answer.
Option (c) They were easy to cross. When two pea plants with different features are crossed or bred to each other, the process is said to as hybridization and the offsprings are referred to as hybrids. Thus, this is not only the correct option. So, this is an incorrect answer.
Option (d) Their anthers could be removed before pollination. The anther can be removed so that the flower could not self-fertilize and the pollen can be transfer to another flower of a different plant. Thus, this is not only the correct option. So, this is an incorrect answer.
Experimental advantages of using pea plants included (d) all of the above were advantages.

- When beta-lactamase was isolated from Staphylcoccus aureus and treated with a phosphorylating agent, only the active site, serine was phosphorylated. Additionally, the serine was found to constitute 0.35% (by weight) of this beta-lactamase enzyme. Using this, calculate the molecular weight of this enzyme and estimate the number of amino acids present in the polypeptide.arrow_forwardBased on your results from the Mannitol Salt Agar (MSA) media, which of your bacteria were mannitol fermenters and which were not mannitol fermenters?arrow_forwardhelp tutor pleasearrow_forward
- Q8. A researcher wants to study the effectiveness of a pill intended to reduce stomach heartburn in pregnant women. The researcher chooses randomly 400 women to participate in this experiment for 9 months of their pregnancy period. They all need to have the same diet. The researcher designs two groups of 200 participants: One group take the real medication intended to reduce heartburn, while the other group take placebo medication. In this study what are: Independent variable: Dependent variable: Control variable: Experimental group: " Control group: If the participants do not know who is consuming the real pills and who is consuming the sugar pills. This study is It happens that 40% of the participants do not find the treatment helpful and drop out after 6 months. The researcher throws out the data from subjects that drop out.
