Answer:
26.3 %
Explanation:
In the given question,
The probability of boys is given that is - 51.3%
Therefore the probability of girls will be = 100- 51.3
= 49.7%
The 51.3% probability of boys per thousand individual can be expressed as 513/1000= 0.513 P(B)
The 49.7% probability of girls per thousand individuals can be expressed as 497/1000= 0.497 P(G)
Now to calculate the probability that the first ans second child both are boys
We will fuse formula= P(B) x P(B)
= 0.513 x 0.513
= 0.263
Thus, 26.3 % is correct.
Specialization is a method of production whereby an entity focuses on the production of a limited scope of goods to gain a greater degree of efficiency. Many countries, for example, specialize in producing the goods and services that are native to their part of the world, and they trade for other goods and services. This specialization is, therefore, the basis of global trade, as few countries have enough production capacity to be completely self-sustaining.

Duckweed performs photosynthesis. Photosynthesis produces oxygen. They take in carbon dioxide and produce oxygen. So, when it is kept in the light cycle it will produce oxygen which will get dissolved in the water.
But the flask with water does not contain dissolved oxygen. So, at the end of light cycle the flask containing the plant will have more DO.
Now, in dark the plant does not produce oxygen. Instead it uses it to break the glucose and produce carbon dioxide. While this is not the case with the flask without the weed.
So, the flask without the plant will have more DO then the flask with the plant.
So, at the end of light cycle the flask with the weed will have more oxygen while at the end of dark cycle the flask with water will have more DO.
