<span>D. Wetlands are salty, but lakes and ponds are fresh.
</span>
The answer is C. Hope it helps.
Clay, slit and sand are carried by suspension.
rocks are dissolved by salts and acids to form a solution.
The question is incomplete as it does not have the options which are:
A) test cross
B) two-point test-cross
C) three-point test-cross
D) chi-square analysis
E) recombination frequency (r) calculation
Answer:
D) chi-square analysis
Explanation:
Chi-square analysis is a test which is used to study the relationship between the variables of a population. The Chi-square test is performed to test if the observed results are due to chance or is real.
To test this a null hypothesis is formulated which says that there is no relation between the variables. The chi-square test is used in various disciplines but in molecular biology, there are used in the linkage mapping and the Mendelian crosses.
Thus, Option-D is correct.
Answer:
Nitrogen
Explanation:
The Percentage of given gases in atmosphere:
Oxygen = O₂ = 20.95 %
Nitrogen = N₂ = 78.08%
Argon = Ar = 0.93%
Ozone = O₃ = 0.000004%
Nitrogen is most abundant gas in atmosphere while oxygen is second most abundant gas. The nitrogen and oxygen are present in diatomic form such as O₂ and N₂.
Water vapors are also present but the percentage vary according to location. In hot humid areas the percentage of water is 0- 4% and it is third abundant gas.
The percentage of other gases in atmosphere are given below:
CO₂ = 0.0360%
Ne = 0.0018%
He = 0.0005%
CH₄ = 0.00017 %
N₂O = 0.0003%
H₂ = 0.00005%
The study of life is called Biology
