The pH indicator bromothymol blue turns yellow when CO₂ gas is added to a

To determine how long it takes a solution containing algae and the indicator to turn blue under different intensities of light. Option B.

<h3>Photosynthesis</h3>

During photosynthesis, green plants use their green pigments to absorb light and drive the reaction between carbon dioxide and water to produce carbohydrates. The equation is as below:

6CO_2 + 6H_2O --- > C_6H_1_2O_6 + 6O_2

Thus, in the experimental setup, the algae will gradually consume  CO₂ to produce carbohydrates.

Since bromothymol blue turns blue from yellow when  CO₂ is removed from a solution, its function in the setup would be to indicate when all the  CO₂ has been consumed by the algae.

Two linked genes, A and B, are separated by 18 cM. A man with genotype AB/ab marries a woman who is ab/ab. The man’s father was
kolbaska11 [484]

Answer:

a) 9%.  

b) 16.8%.

Explanation:

a).

We are provided with the information that Two linked genes, A and B, are separated by 18 cM (centiMorgan). i.e the recombinant frequency is 18%

Also , the man's genotype is AB/ab... This only result to one explanation, that The man will definitely produce 18% of recombinant gametes which entails

9% Ab & 9% aB

i.e 0.09 Ab & 0.09 aB

On the other-hand, The mother ab/ab have tendency to produce just one single type of gamete which is ab

∴

The probability that their first child will be Ab/ab will be

Pr ( Ab/ab) = (0.09) x (1)

= 0.09

= 9%.  

b).

If the father produces 18% of recombinant gametes which entails

9% Ab & 9% aB , this typically implies that the number of the non-recombinant gametes will be;

100%-18% = 82%  ( non-recombinant gametes)

i.e genotype AB/ab = 82%

AB =41%; ab = 41%

AB = 0.41 ; ab = 0.41

Now, the probability that their first two children will both be ab/ab:

Using Multiplication Rule to calculate the probability that their first two children (ab/ab); we have:

 (0.41)(1) ×(0.41)(1)

= 0.1681

= 16.8%.

1-. CONTESTE FALSO (F) O VERDADERO
jeka57 [31]

Answer:

A) Falso, cuando un resorte se estira, este comienza a acumular energía potencial. Al soltar el resorte, este tratara de volver a su forma natural, consumiendo la energía potencial y transformándola en energía cinética.

B) Falso. Potencia esta definido como la cantidad de trabajo efectuado por unidad de tiempo, a mayor potencia, mas rápido se completa un trabajo.

C) Verdadero, el trabajo es escalar, pues resulta de un producto punto entre dos vectores, la fuerza y el desplazamiento.

D) Falso, el cambio en la energía cinética de un cuerpo es igual al trabajo neto aplicado sobre ese cuerpo. Es decir, si le aplico trabajo a un cuerpo, estoy cambiando su energía cinética.

E) Falso, la fuerza del vagón sobre los pasajeros NO es constate, ya que esta fuerza esta relacionada con la velocidad a la que se mueve el vagón, y sabemos que la velocidad del vagón va cambiado durante el trayecto (podemos experimentar esta fuerza al pasar de una horizontal a una pendiente muy pronunciada, ya que hay un gran cambio de velocidad, y si hay cambio de velocidad, hay aceleración, y por la tercera ley de Newton, si hay aceleración, hay fuerza), pero si es verdad que esta fuerza es un factor importante al diseñar una montaña rusa.
