Answer:

Adenina (30%), citosina (15%), guanina (15%) o timina (40%)

Explicación:

El 30% de las bases nitrogenadas totales lo ocupa la adenina, el 15% de las bases nitrogenadas totales corresponde a la citosina, el 15% de las bases nitrogenadas totales toma la guanina y el 40% restante de las bases nitrogenadas totales lo ocupa la timina. Entonces, al combinar todos estos porcentajes, obtenemos el 100 por ciento del volumen del ácido desoxirribonucleico (ADN).

if a human cell with a chromosome number of 46 undergoes meiosis, what number of chromosomes will be in each daughter cell?
KiRa [710]

Explanation:

It's a piece of cake. Here we are provided with the information that a human cell with a chromosome number of 46, undergoes meiosis, what number of chromosomes will be in each daughter cell.

To solve this question first you must be aware about the word meiosis. Meiosis is a type of cell division. It's end product results in the formation of four daughter cells each having half the number of chromosomes as that of the parent cell.

Did you notice? That formed daughter cell will have half the number of chromosomes as that of the parent cell. Hence, 23 chromosomes will be in each daughter cell.

This occurs during a process called Gene Expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions

Succession can be of two types. 1. Primary succession 2.Secondary succession

Primary succession occurs on lands where there was no life before. With time, plants start to grow here and a community is developed.

Secondary succession occurs on lands that have been destroyed due to any disturbances like a flood or a fire. Over time, new plants start to grow on this land and a community is developed.
