Answer:
d
Explanation:
Answer:
D. Both X and Y chromosomes

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.
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.

Write down the classes of foods digested in the gut from the mouth to the duodenum?
Explanation:
The chyme is gradually pushed down the duodenum by peristaltic waves which flow down the length of the digestive tract. Most of the digestion of the protein, fats and carbohydrate in the chyme is done by the enzymes in the duodenum, before the resultant mixture is passed further into the small intestine.

The Hawaiian honeycreeper bird has a mutualistic relationship with the Hawaiian silversword plants. The Hawaiian silversword plants have been widely destroyed due to human development in the area
Which of the following explanations BEST predicts how human development will affect the Hawaiian honeycreeper bird population?
Answer:
The Hawaiian honeycreeper bird population will decrease because they rely on the Hawaiian silversword plants for survival.
Explanation:
The destruction of Hawaiian silversword plants due to human development hurts the Hawaiian honeycreeper bird population as the bird exists in a mutual relationship with the plants.
What is the relationship between Hawaiian silversword plants and honeycreeper birds?Hawaiian honeycreeper bird has a mutual relationship with Hawaiian silversword plants, where the bird feeds on the plant's nectar and pollinates the flowers. If the plant population decreases, it will result in a reduced food supply for the bird which decreases their population size.
Loss of the silversword plants also destroys their habitat which can impact their population. Therefore, human development results in a decrease in the Hawaiian honeycreeper bird population.
However, the loss of the honeycreeper bird population also affects the ecosystem as they play a very important role in seed dispersal and plant reproduction which reduces plant diversity and also negatively impact other species that depend on the Hawaiian silversword plants for food.
Therefore, the destruction of Hawaiian silversword plants hurts the Hawaiian honeycreeper bird population as the bird exists in a mutual relationship with the plants.

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
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 cross3) 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 white5) Based on the four offspring observed, you CAN know for certain that the purple parent is Pp.

Which statement is an example of a qualitative measurement?
A
That structure is four meters long.
B
Water can have a cold temperature.
с
This solution has a temperature of 56° C.
D
Light travels at 3 x 108 m/s.
Answer:
The correct answer is - B. Water can have a cold temperature.
Explanation:
Qualitative measurement is a type of measurement that is not based on numerical or numbers but is completely based on the quality of the particular thing. It can be distinguished on basis of the term quality which is based on the character of the substance or condition whereas quantitive is which is based on numerics or numbers.
Among these, all the three choices have numerical measurement but the choice in which it is expressed that water can have cold temperature is qualitative measurement as cold is the quality of the water here.
