Why is it important to study grouse habitat selection and demography relative to human land use practices?

1 answer:

6 0

Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.

In The Origin of Species, Darwin argued that the mechanism of descent with modification was ________. In The Origin of Species,

alexira [117]

Answer:

Natural selection

Explanation:

According to Darwin, natural selection is the mechanism through which evolution takes place. Natural selection is the mechanism through which the heritable traits characteristic changes in an organism over the generations. Variations in traits of organisms are passed down through the generations and each generation has their genes affected by the environment.

The inflammation process (2 pts)

Cloud [144]

Answer: All of the above.

Explanation: Inflammation process is part of the immune response to fight against infection or injury. It works together with the complement system that promotes the ability of antibodies and phagocytes to remove microorganisms and damaged cells from site of infection. Cytokines are produced by T-helper cells and macrophages to regulate inflammation by producing cytokines that sends positive feedback for the initiation of inflammation process. Promoting the production of chemicals, proteins and enzymes for chemotaxis and diapedesis of phagocytes.

Basically during inflammation the site of infection or injury will change colour and turn red, it will swell and cause the production of pyrogens which will result in fever symptoms due to raise of body temperature.

Assume that the mutation rate for a given gene is 1 × 10−6 mutations per generation. For that gene, how many mutations would be

sertanlavr [38]

Answer:

500

Explanation:

Mutation rate is largely known as changes that occur in the frequency of a particular gene over an extended period of time

So given that;

the mutation rate of a particular gene = 1 × 10⁻⁶

The expected mutations after 500 million sperm are examined will be:

= (1 × 10⁻⁶)×(500,000,000)

= 500

Thus, The expected mutations = 500

The following picture shows the three primary types of plate boundaries. Which boundary is being shown in label A? an arrow poin

IceJOKER [234]

Answer:

The label A corresponds to Convergent boundary zones

Explanation:

When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped volcanic islands, the island arches. Subduction zones coincide with deep-sea trenches or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.
