Answer:
Phenotypes are physical attributes. Genotypes are the alleles.
The phenotypes are 75% green peas and 25% yellow peas. This is because the capital G is a dominant allele and green is the dominant attribute and as long as 1 G is present, then the pea will appear green.
The genotypes are 25% GG, 50% Gg, and 25% gg.

Answer:
- Luis quiere saber si los cristales de yodo pueden disuelverse en distintos líquidos
- Luis necesita cristales de yodo, agua, alcohol y aceite mineral
- La hipótesis de trabajo puede ser: "los cristales de yodo se disuelven en distintos líquidos", con lo cual la hipótesis alternativa indicaría que los cristales de iodo no se disuelven
- La recopilación de los datos puede consistir en la realización de tres experimentos en los cuales los cristales de yodo son sumergidos en agua (1° experimento), alcohol (2° experimento) y aceite (3° experimento).
Explanation:
En el método científico, la pregunta científica refiere a una cuestión particular la cual es planteada con el objetivo de responder algún aspecto particular del mundo real. A partir del planteamiento de una pregunta científica es posible formular dos hipotésis denominadas hipotésis nula e hipótesis alternativa, las cuales representan supocisiones contrapuestas que permiten contestar dicha cuestión. Subsecuentemente, los científicos realizan experimentos y/o observaciones que permiten recopilar datos cuyos resultados son utilizados para confirmar (o rechazar) la hipótesis nula. Por otra parte, es necesario resaltar que durante el proceso de experimentación se requiere de la utilización de controles positivos y negativos que permitirán corroborar si dichos experimentos fueron realizados correctamente.
Answer: The transcription and translation process allows trna and rrna molecules to be used to synthesize wide variety of polypeptides.
Explanation:
DNA molecule is made up of information for coding proteins. This information is passed on the mRNA during a process known as transcription. Transcription is the first of many steps of DNA based gene expression in which a part of the segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase.
Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language. During the process of transcription, a DNA sequence is read by an RNA polymerase, which gives a complementary, antiparallel RNA strand referred to as a primary transcript.
A large diversity among genes is followed by a large amount of various mRNA molecules. However, the ribosomes consist of rRNA, which is included in the process of translation. Translation is the process whereby ribosomes in the cytoplasm or ER synthesize proteins after the process of transcription of DNA to RNA in the cell's nucleus. The overall process is called gene expression.
The smallest of the three types of RNA is tRNA, which has only 75 to 95 nucleotides and has a role in bringing particular amino acids to the growing polypeptide. It can be concluded that mRNA contribute to the diversity of polypeptide molecules due to the fact that it carries an information about their synthesis.
