Answer:
A Wheat Harvest System Simulation Model (WHSSM) was developed and used to study the effect of different climatic conditions on returns in three main wheat growing regions in Australia. The study was carried out using 15 years (1991–2005) historical weather data for Goondiwindi, Scaddan and Tamworth. It is found that the weather conditions during the harvest period could have a significant influence on the predicted returns. For the given farm setups, the optimum harvest moisture contents for different climatic regions were quite different. For the given control parameters, the optimum harvest moisture contents for Goondiwindi, Scaddan and Tamworth were 14, 15 and 17%, respectively. Growers in a dry and warm location (e.g. Goondiwindi) would be able to delay their harvests to a later date. They would also be able to gain a better return than growers in wet and cool regions (e.g. Tamworth or Scaddan). This paper highlights the importance of optimising the integration between agricultural machinery used, crop performance and perceived weather risk.

Answer:
Option D
Neither gene is significantly different
Explanation:
Tan Spore gene
Cross-over
Observed=189
Expected=177
Observed-Expected=189-177=12
Standard deviation,
Non-cross-over
Cross-over
Observed=139
Expected=151
Observed-Expected=139-151=-12
Standard deviation,
Chi-square value=0.813559+0.953642=1.767202
Rounding off to three decimal places, chi-square value is 1.767
Gray Spore Gene
Cross-over
Observed=204
Expected=216
Observed-Expected=204-216=12
Standard deviation,
Non-cross-over
Cross-over
Observed=124
Expected=112
Observed-Expected=124-112=12
Standard deviation,
Chi-square value=0.666667+1.285714=1.952381
Rounding off to three decimal places, chi-square value is 1.952
Degree of freedom=n-1 where n is sample size, the sample size here are 2 hence degree of freedom is 2-1=1
From chi-square table, when degree of freedom is 1, chi-square value is 3.841
Since for both genes, the chi-square values are less than 3.841 then we should accept that data since it’s not significantly different
There is a difference in color between the reactants and the product. Also, a gas and a solid bread loaf were produced, compared to the liquid or powder forms of the reactants.
Answer:
In humans, there is a readiness to perceive ourselves on priority and favorably. This is one of the reasons that helps in increasing the remembering memories of events that are favorable to the individual which results in benefits, it is known as self-serving bias.
Self-esteem is something that helps in knowing the self-worth and the importance of happiness of one's own. Being aware of environmental control result in achieving better in life and experienced less stress. The potential use of the capabilities of individuals results in increasing awareness about what is the purpose of the life of an individual.
Answer:
The correct answer is option (B) "95".
Explanation:
Nucleic acids in double-stranded molecules follow certain rules for complementary bonding. In Earth's eukaryotic cells, adenine is attached to uracil and guanine is attached to cytosine. The proposed alien nucleic acids are not that different from Earth's nucleic acids, because isoAdenine (iA) could only be attached to uracil. Therefore, since the initial analysis shows that 95 of the 320 nucleic acids are uracil, 95 nucleotides containing the base isoAdenine (iA) would be found in the double-stranded molecule.
