Answer: The correct answer is-

B. Count the number of species, and measure their relative abundance.

Biodiversity of ecosystem can be described as variability among different life forms  ( such as plants, animals, and microbes) that are present within an ecosystem.  

An ecosystem biodiversity can be measured by counting the total number of living organisms, which are present in that ecosystem by using several indices.

For instance Simpson diversity index, which includes measuring species number present in an ecosystem and their relative abundance, termed as as species richness.

Thus, option B). count the number of species, and measure their relative abundance is the right answer.

To assess Mendel’s law of segregation using tomatoes, a true-breeding tall variety (SS) is crossed with a true-breeding short va
lapo4ka [179]

Answer:

0.949367 ≈ 0.95.

Explanation:

The chi square analysis can be done by the formula as follows:

Chi square = (O-E)²/E

Here, O is observed value and E is expected value.

The tall trait follows the Mendel's law, this means the cross between F1 results in the formation of progeny with ratio 3( tall) : 1 (short).

The observed values for set I is  63 tall, 16 short.

The expected value for tall plant =  \frac{3}{4}\times79 = 59.25 .

The expected value for short plant = \frac{1}{4}\times79 = 19.75.

Put these value in the formula for chi square analysis:

For tall plants = ( 63 - 59.25)²/ 59.25= 0.237.

For short plants = (16 - 19.75)²/ 19.75 = 0.712

Total value for set I = 0.237 + 0.712 = 0.95.

Thus, the answer is 0.95.
