In Minnesota, ecologists want to restore an abandoned cow pasture into a prairie ecosystem. The soil in the abandoned pasture is homogenous with high nitrogen content and is dominated by bunch grasses that prefer high nitrogen conditions and inhibit the establishment of other native prairie plant species. The ecologists decide to introduce native pocket gophers to the prairie to facilitate the restoration. Which of the following factors is improved by adding pocket gophers to the abandoned pasture?
A. Interspecific plant interactions inhibit plant growth and establishment.
B. Colonization is limited by poor dispersing plant species.
C. Plant establishment is limited by suitable "safe" sites that are protected from weather extremes
D. Herbivory can restrict establishment of plants that are attractive to herbivores.

Answers

Answer:

The factor that is improved by adding pocket gophers to an abandoned pasture is:

B. Colonization is limited by poor dispersing plant species.

Explanation:

In ecological management, colonization describes the action by a plant or animal to establish itself in an area.  When pocket gophers are added to an abandoned pasture, the area is repopulated by these rodents.  By their nature, pocket gophers move some quantity of soil annually, thereby aerating the soil.  Moreover, they build tunnels, which they later abandon for other species as natural habitat.  They also leave some waste products to fertilize the soil, making the ecosystem alive again.

This is an example of which factor that affects biodiversity?

nonnative species

habitat destruction

(poaching)

Explanation:

Or you can just say D

Several years ago, fish from Asia were introduced into ponds in the United States. They have rapidly grown in numbers and use up a lot of the food and habitats of other fish that are natural to the United States. Thus, option "D" is correct.

Why Poaching is illegal?

Poaching is the act of illegally killing an animal. The very prominent subject of poaching is the rhino, some species of which are now virtually extinct due to extensive illegal hunting. However, many other animals are also poached. For example, elephants are poached for the ivory in their tusks. Tigers are poached as trophy animals or for traditional medicine. Sea turtles and lemurs also suffer a similar fate for similar reasons.

Thus, option "D" is correct.

In a few months, you receive a brief note from the breeder that he checked the four offspring and three have the purple trait and one has the white trait. Since only four offspring were produced, there are not necessarily enough offspring to observe the ratio you predicted. What is the probability of observing three purple and one white offspring: If the purple parent is Pp

Answers

Complete question:

1) Inspired by Gregor Mendel, you visit a local greenhouse to see what a pea plant looks like in person. You spot a plant in the corner and immediately notice that it exhibits the purple trait of the flower color character. This character is controlled by one gene with two alleles, the dominant purple P allele, and the recessive white p allele. Identify what you know for certain based on your observation. Check all that apply.

You know the genotype of the plant. This plant has at least one copy of the P allele.This plant must be heterozygous with respect to the flower color gene.You know the phenotype of the plant.

2) In another corner of the greenhouse, you find another pea plant. This plant, however, exhibits the white trait of the flower color character. The greenhouse plant breeder approaches you and mentions that he plans to cross-fertilize the two plants that you have seen. He offers to let you know how the offspring turn out. Without realizing it, the breeder is actually conducting a

dihybrid cross testcross monohybrid cross

3) If you were able to examine hundreds of offspring from this cross, what ratio of purple flowers to white flowers would you observe:

If the purple parent is PP ---------If the purple parent is Pp ----------

4) In a few months, you receive a brief note from the breeder that he checked the four offspring and three have the purple trait and one has the white trait. Since only four offspring were produced, there are not necessarily enough offspring to observe the ratio you predicted. What is the probability of observing three purple and one white offspring:

If the purple parent is Pp? ----------If the purple parent is PP? ----------

5) Based on the four offspring observed, you --------- (can/ cannot) know for certain whether the purple parent is Pp or PP.

Answer:

1)

This plant has at least one copy of the P allele. Because the plant is purple and the P allele is the one that codifies for this color. You know the phenotype of the plant. You can see that the plant has purple flowers, so you know its phenotype regarding flower color.

2) A test cross

3)

If the purple parent is PP → 1:0 (100% heterozygous purple flowers, Pp)If the purple parent is Pp → 1:1 (50% Purple Pp, and 50% white pp)

4)

If the purple parent is Pp? 3/4 = 75% purple and  1/4 = 25% whiteIf the purple parent is PP? 4/4 = 1 = 100% purple and 0 white

5) Based on the four offspring observed, you CAN know for certain that the purple parent is Pp.

Researchers find to imitate photosynthesis through utilizing concentrated carbon dioxide and suitable catalyzers. By this process, they were able to create fuels from solar energy by a process of artificial photosynthesis to collect high amounts of energy from the sun. Peidong Yang, a chemist at UC Berkeley, successfully developed the first photosynthetic biohybrid system (PBS) in 2015.PBS in which semiconductor it was treated as a first-generation PBS in which semiconductors and live bacteria are used to perform photosynthesis just like real leaves, absorb solar energy and formation of the chemical product occur by using water and CO2, releasing O2. This technology is termed artificial photosynthesis, and if this technology continues to improve, surely it will act as the future of energy.
