Answer:

Some of the reasons why marathon runners often collapse near the finishing line is because the build-up of lactic acid in the blood during the run triggers abnormal heart rhythms and also exhaustion, emotional stress, dehydration and heat stroke.

What is one way that temperature affects mechanical weathering?

Ket [755]

Answer:

Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens.

A key difference between primary cell cultures and secondary cell lines is that:____.a. primary cell cultures tend to stay alive

ivann1987 [24]

Answer:

d. the cells in primary cell cultures do not divide.

A key difference between primary cell cultures and secondary cell lines is that the cells in primary cell cultures do not divide.

hope it helped you 

Explanation:

The main difference between primary and secondary cell culture is that the primary cell culture contains the cells directly obtained from host tissue, whereas the secondary cell culture contains sub-cultured cells from primary cell culture.

this involves small scale changes within a community that occur repeatedly over the life of that community

Akimi4 [234]

Explanation:

Succession involves small scale changes within a community that occur repeatedly over the life of that community.

Ecological communities are highly dynamic- they gradually evolve. Typically their progression involves:

colonizing species exploiting uninhabited areas (Primary succession)
becoming a habitable and increasingly complex community
there is increased diversity of organisms (Secondary)

Further Explanation:

The makeup of biological communities is crucial to defining Primary and Secondary succession; eventually, through changes in this makeup, a steady-state or equilibrium is reached called a climax community. While Primary succession starts off with the modification of a previously unoccupied area along with increasing variation; secondary succession begins after major disruption in the community such as fires, storms and flooding.

However, the process of becoming a climax community can be pretty complicated- it is very dependent on other factors like temperature and rainfall. Communities that experience rapid change, frequent major disruptions and even human intervention, are less likely to attain a stable equilibrium and may never become climax communities.
