Answer:
F2:
-75% plantas con flores púrpuras
- 25% plantas con flores blancas
Explanation:
La F1 de un cruzamiento entre líneas puras para un rasgo dominante monogénico (en este caso, color de la flor) es siempre igual al fenotipo para el carácter dominante (en este caso, plantas con flores púrpuras). En este ejemplo, el alelo dominante que codifica para el color púrpura enmascara la expresión del alelo recesivo (flores blancas) en plantas F1 heterocigotas. Por otra parte, el cruzamiento entre plantas F1 con genotipo heterocigoto producirá una F2 con una proporción fenotípica 3:1 (es decir, 3 plantas con fenotipo dominante por cada planta con fenotipo recesivo), lo cual es igual a un 75% de plantas con fenotipo dominante (tres plantas: una con genotipo homocigota dominante y 2 con genotipo heterocigoto) y un 25% de plantas con fenotipo recesivo (una planta con genotipo homocigota recesivo). Esto sucede porque los alelos dominante y recesivo responsables del color de la flor segregan independientemente durante la formación de los gametos en plantas F1 heterocigotas.
I don't know what the expieraments about but I can say its rather B or C the independent variable is the variable that you are testing.
The
answer is B cell lineage. There two stages of B cells Lineage first is the early pro b
cell -D and J rearrangement and the late Pro B cell - V-DJ rearrangement. These
rearrangements refer to the Heavy chain and activation of KIT causes the B-cell
to proliferate.
Answer:
Answer is true.
Explanation:
A systemic circulation involves the supply of functional blood which is known as the oxygenated blood to cells or body tissues, and subsequently picks up carbon [iv] oxide and other waste products.
The erythrocytes are the red blood cells which when mixed with oxygen become bright red in color.
Note that, systemic tissues are where the oxygen from the heart are being released and the waste products are absorbed.
Answer: a. the amount of water
Independent variable can be defined as a variable which can be changed or manipulated in an experimental set up to record and observe it's effect on the dependent variable. A dependent variable is a variable which is dependent on the independent variable. The outcome of the dependent variable is the result of the experiment. A controlled variable is a variable which does not change in a reaction, and kept as a constant.
1. Here, in the given situation, the amount of water is an independent variable, as it can be manipulated or change in an experiment and it's impact on the growth of plant, which is a dependent variable needs to be observed.
2.Here, in the given, situation, the type of plant is a constant or control variable, as it is irrespective of the changes that occur in the dependent variable with respect to the independent variable.
