user100 [1]

Answer:

C) As Sachin Tendulkar is short in height himself, these genes of short height may get transferred in to his children. Most likely.

Explanation:

All the above options except one cannot be genetically determined.

A) This option is absolutely absurd because how can Sachin Tendulkar's information determine who is children are gonna marry

B)It cannot  be determined.

C) As Sachin Tendulkar is short in height himself, these genes of short height may get transferred in to his children. Most likely.

D) Sachin Tendulkar is a famous batsman that does not mean his children also have to be famous batsmen

1: Which of the following parts of a dry cell corresponds to the salt bridge shown in the diagram attached inside?
Illusion [34]
I believe the correct answer from the choices listed above is option B. The salt bridge in the diagram would be a paste. I would like to assume that the paste consists of the Na2SO4 salt. <span>The </span>purpose<span> of a </span>salt bridge<span> is not to move electrons from the electrolyte, rather to maintain charge balance because the electrons are moving from one half </span>cell<span> to the other.</span>

Water falls without splashing at a rate of 0.200 L/s from a height of 3.60 m into a 0.730 kg bucket on a scale. If the bucket is
dimaraw [331]

Answer:

15.106 N

Explanation:

From the given information,

The weight of the bucket can be calculated as:

W_b = m_bg =  \\ \\  W_b = (0.730 \  kg) ( 9.80 \ m/s^2) \\ \\ W_b = 7.154 \ N

The mass of the water accumulated in the bucket after 3.20s is:

m_w= (0.20 \ L/s) ( 3.20)s

m _w=0.64 \ kg

To determine the weight of the water accumulated in the bucket, we have:

W_w = m_w g

W_w = ( 0.64  \ kg )(9.80\  m  \  /s^2)

W_w = 6.272 \ N

For the speed of the water before hitting the bucket; we have:

v = \sqrt{2gh}

v = \sqrt{2*9.80 \ m/s^2 * 3.60 \ m}

v = 8.4 m/s

Now, the force required to stop the water later when it already hit the bucket is:

F = v ( \dfrac {dm}{dt} )

F = (8.4 \ m/s)( 0.200 \ L/s)

F = 1.68 N

Finally, the reading scale is:

F_{scale = 7.154 N + 6.272 N + 1.68 N

= 15.106 N

What is the temperature used for the extension step?
lisabon 2012 [21]
<h2>72°C</h2>

Explanation:

  • The polymerase chain response (PCR) could be a strategy to quickly open up groupings of DNA.
  • Amid a normal PCR, format DNA (containing the locale of intrigued) is blended with deoxynucleotides (dNTPs), a DNA polymerase and small segments of DNA called primers.
  • PCR involves a series of temperature cycles.
  • The temperature used for the extension step is 72°C.
  • The temperature that is used during the extension phase is dependent on the DNA polymerase that is used.
  • Amid the expansion step (ordinarily 68°C-72°C) the polymerase amplifies the groundwork to create an early DNA strand. This prepare is rehashed different times
  • Generally at this stage, the reaction mixture is heated to a temperature intermediate between the denaturation and annealing temperatures. The optimal temperature for Taq polymerase is 72°C.
