Answer:
No
Explanation:
E. coli are prokaryotes, meaning they do not have membrane-bound organelles like mitochondria.
However, they do perform respiration to produce the energy needed for cellular processes. They can perform both aerobic respiration (in the presence of oxygen) and anaerobic respiration (in the absence of oxygen).
Since they don't have any membrane-bound organelles, these processes take place in the cytoplasm
The characteristics of contour lines are:
1. A closed curve shaped contour line;
2. Contour lines are always perpendicular to the flow of water that flows on the surface of the land;
3. Contour lines are always horizontal, not branched, and do not intersect;
4. Contour lines will not be seen if it passes through a building;
5. Contour lines are only designated at a certain height angle;
Explanation:
Contour lines or called tranches, high lines, or horizontal high lines, are imaginary lines in an area or area on the map that connects and shows several points on the map that have the same height. This line further shows the movement or development of the ups and downs of a state of land.
For example, a contour line is indicated by the number + 25 meters, meaning this contour line connects points that have the same elevation angle or height + 25 meters to a certain elevation or height angle.

Answer:
Verdadero
Explanation:
Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.
Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.
Genotipo:
- Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)
- Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)
- Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)
Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.
Sin embargo, si tenemos los siguientes genotipos acompañando esta información:
- MM--> Amarillo
- Mm--> Amarillo
- mm --> Rojo
Recién ahora podemos deducir que el caracter dominante es el amarillo.
Answer:
Gregor Mendel chose pea plants for his experiments because they are easy to raise, have many offspring per mating, can fertilize themselves and have varieties in genotype and phenotype that are easily observable. These characteristics make pea plants ideal in the study of genetics and heredity.
