Nitrites are 307880 115 and control is 30 8112 1250
Let X be nitrate group and let Y be a control group.
If ∪X-∪Y∠0 then we can say that nitrates decrease the number of amino acids which is taken.
Hypothesis test.
H0:∪X-∪Y=0Vs. Where H1:∪X-∪Y∠0.
Sample for X = 7880 and Y = 8112 and Sx∧2=variance sample for X = 1115∧2 = 1243225 and Sy∧2 = variancesample for Y= 1250∧2 = 1562500. The size of the sample = 30 for both cases.
Test statistics is Z =((7880-8112)-0)/squareroot (1243225/30+1562500/30) = 0.758623)
Value of P = P(Z∠z)
=P(Z∠-0.758623).
Since P-value is greater than the importance of 0.02, we can not reject the null hypothesis. The conclusion is that ∪x-∪y =0 a good example is nitrates does not decrease the number of amino acid which is taken.
Answer:
Thymine Adenine Guanine Cytosine
Explanation:
Have a great day.
The possible number of main effect is THREE.
Main effects refers to the major conditions that are specify in the experiment; these are: room temperature, noise level and room colour. These three factors are manipulated in the designed experiment.
Answer:
C. Only 1, 3 and 4
Explanation:
Deforestation is the process of cutting down trees by man, which eventually lead to the the sparseness of trees in otherwise forested areas. The reasons for cutting trees by man may include: habitation by man, clearing the land for agriculture or grazing, or using the timber for fuel, construction or manufacturing as well as mining of minerals.
Deforestation leads to many adverse effects on both man and his environment. These adverse effects include:
Loss of biodiversity in the forests which may lead to extinction of species.; when forest areas are cleared, plants and animals who live in these forests lose their homes and some may eventually die off due to inability to survive in other habitats
Increase in temperature of the earth: Trees serves to cool the earth by removing some gases which cause heating of the earth from the earth. Such gases include carbon dioxide. When these tree are removed, these gases accumulate in the atmosphere leading to increase in earth's temperature.
Also, since tree absorb some gases while releasing others into the atmosphere, when these trees are cut, there would be an imbalance of these atmospheric gases.
Autotrophs are able to make their own food and sustain themselves without consuming other organic molecules.
Hope this helps out
