Explain how the edges and corridors can strongly influence landscape biodiversity
Dahasolnce [82]

Answer:

The edges or boundaries between the ecosystems and within it are the illustrating characteristics of landscapes. In a landscape, the biodiversity is affected by the composition of the landscape itself. When an area possesses boundaries or edges, which minimize the area of the habitat, it also starts to minimize the number of species, which can associate with the communities.  

The multiplication of edge species can exhibit both negative and positive influences on the biodiversity of a community. On the other hand, corridors refer to the region associated with the populations of wildlife distinguished by human activities like road construction. The prime objective of designing habitat corridors is to enhance biodiversity. The corridors that have been protracted to other habitat patches can reinstate a certain degree of space and at the same time reestablish certain chances for genetic diversity.

Darwin examined remains of extinct organisms while on his journey. The remains had been preserved in rock for a very long time.

The remains are called fossils. Fossils are remnants of animals, plants, or microorganisms that have been solidified in the process of fossilization, where the organism is surrounded by sediment, minerals, and other solid objects which are compressed and heated around the organism over time. This forms a solid mass with the preserved organism inside, other known as a fossil.

How do cigarettes and radiation cause cancer? View Available Hint(s) How do cigarettes and radiation cause cancer? by destroying
blagie [28]

Answer: B.  by toxic chemicals (in smoke) or radiation that can damage the DNA in cells.

Explanation:

The carcinogens presents in cigerates covalently bind to DNA and form DNA adducts which results into miscoding (e.g., insertion of the wrong base) during replication of DNA and this genetic mutation causes uncontrolled cellular growth which causes cancer.

Ionising radiation including X-rays, radioactive particles, and gamma rays,can cause cancer by damaging DNA. high-energy radiation damages DNA and cause genetic mutation same as cigerates and causes cancer.

Both toxic chemicals (in smoke) or radiation damages DNA inthe cells which leads to cancer.

Hence, the correct option is B.
