Answer:
The presence of excess fertilizer in the water leads to algal blooms as the level of phytoplankton increases initially due to an influx of nutrients derived from fertilizers.
Explanation:
The primary nutrients found in fertilizers include nitrogen and phosphorus , which are essential for plant growth. Fertilizers used in agriculture are loaded with nutrients and minerals that contaminate water bodies through runoff, disrupting aquatic ecosystems by depleting oxygen levels because of algal blooms, producing odors and gases, releasing toxins that harm aquatic organisms, deteriorating water quality, and escalating pathogen levels that can trigger life-threatening diseases
The probability of generating plants with white axial flowers is 1/16. Based on the given illustration, all F1 offspring exhibited red axial flowers, indicating that the genes for red and axial traits are dominant over those for white and terminal traits in pea plants. Let's denote the allele for flower color as A (red) and a (white), and for flower position as B (axial) and b (terminal). The genotype of pure-breeding red axial flowers would be AABB, while pure-breeding white terminal flowers are represented as aabb. Crossing these results in F1 genotype AaBb, which shows all red axial flowers. For the F2 generation from AaBb crossed with AaBb, the progeny breakdown is: 9 A_B_ red/axial, 3 A_bb red/terminal, 3 aaB_ white/axial, and 1 aabb white/terminal. Consequently, the chance of generating plants with white axial flowers in the F2 generation is 1/16.
A gene is a segment of DNA that typically contains the code for a particular protein influencing a specific trait, while an allele is a segment (a version) of that gene. The correct choice among the options is option "D".
I believe the correct answer is D.
My reasoning for this conclusion is that coyotes from various groups would have encountered diseases and potentially developed immunity (for those that survived), allowing them to migrate to other coyote populations where those individuals may introduce the illness.
