Answer:
D. Agronomist
Explanation:
Agronomists are professionals that study how to make soils more productive (in terms of food) around the world. Soil pH is an index that calculates the acidity/alkalinity of the soil, which is indicated on a 14-point scale (pH equal to 7 = neutral; pH below 7 = acidic, pH higher than 7 = alkaline). In this regard, it is well known that the pH of the soils drastically affects plant development, and thereby a proper soil pH is fundamental to ensure optimal plant growth (required for nutrient intake). For this purpose, agronomists are in charge of studying and researching the pH of the soils in order to increase crop yields. Nowadays, the pH of the soils can be easily measured by digital soil pH pocket testers that utilize a pH electrode in order to calculate the pH value.
Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.
hope this helps:)
By placing the pots with detergent in the sun and the pots
without detergent in the shade, the student is not comparing the effects that
detergent has in the growing rate of the seeds under the same conditions;
besides, he does not have a control group. Therefore, he will not be able to
determine if the growing rate of the plants were affected by the detergent, the
lack of sunlight, or a combination of both factors.
Answer:
farm hand
Explanation:
because the farm only specializes in cattle
Answer:
Explanation:
<em>The probability of producing plants with white axial flowers would be 1/16.</em>
From the illustration, All F1 individuals had red, axial flowers. It thus means that red and axial genes are dominant over white and terminal genes in the pea plant.
Let us assume that the allele for flower color is A (red) and a (white); and the allele for flower location is B (axial) and b (terminal).
Pure-breeding red, axial flower = AABB
Pure breeding white, terminal flower = aabb
AABB x aabb
F1 genotype = AaBb - all red and axial
At F2:
AaBb x AaBb
Progeny
<em>9 A_B_ red/axial</em>
<em>3 A_bb red/terminal</em>
<em>3 aaB_ white/axial</em>
<em>1 aabb - white/terminal</em>
Hence, the probability of producing plants with white axial flowers in the F2 generation is 1/16.
