Answer:
Linckia laevigata (sometimes called the "blue Linckia" or blue star) is a species of sea star in the shallow waters of tropical Indo-Pacific.
...
Answer;
The correct answer would be Rr.
In a monohybrid cross, the phenotype ratio of 3:1 is obtained only when both the parents are heterozygous for the trait.
In this condition, the heterozygous genotype would be Rr. The phenotype of both the parents would be round seeds (R) as the round is a dominant trait.
The cross of these parents would produce offspring with three types of genotypes RR, Rr, and rr in ratio 1:2:1.
Thus, the phenotypic ratio would come out to be 3 (round seed):1 (wrinkled seed).
In 20 years, many of the country's 411 national parks, monuments and historic sites will suffer damage as sea levels rise, wildfires rage, glaciers melt and iconic wildlife, such as grizzly bears in Wyoming and pikas in Colorado's high-altitude tundra face shrinking habitat and scarce food.
Hope this helps you if I am wrong sorry
Have a great day!

Answer:
Crop rotation
Explanation:
Plant obtain nutrients from the soil. Plantation of crops in soil depletes nutrients from the soil. Crop rotation is one of the methods used for maintaining the nutrient levels and thereby, the productivity of the soil. Crop rotation includes plantation of different crops in the same field. For example, farmers plant legume crops after the non-legume crops. Leguminous plants have Rhizobium bacteria in their root nodules. These bacteria fix nitrogen and restore the lost nitrogen from the soil.
