respitory systym and circulatory system because you need your lungs to breathe and the blood and heart to pump the oxygen into the blood. :))

Just as the organs in an organ system work together to accomplish their task, so the different organ systems also cooperate to keep the body running. For example, the respiratory system and the circulatory system work closely together to deliver oxygen to cells and to get rid of the carbon dioxide the cells produce.

Cytopathic effects are changes in host cells due to.

anzhelika [568]

Answer: viral invasion.

Explanation:Cytopathic effect or cytopathogenic effect (abbreviated CPE) refers to structural changes in host cells that are caused by viral invasion. The infecting virus causes lysis of the host cell or when the cell dies without lysis due to an inability to replicate. Both of these effects occur due to CPEs.

An Asian elephant has a weight of 52,900 newtons. This enormous weight is balanced on four feet. In a circus act, these elephant

Aleonysh [2.5K]

Answer:

Option B, $18.11 \frac{N}{cm^{2}}$

Explanation:

Given-

The average surface area of one foot pad of an elephant is $2920$ $cm^{2}\\$

Weight of an Asian elephant is $52900$ newton

As we know, pressure is equal to total weight divided by total area of the surface on which it is concentrated.

Thus, pressure on one foot pad of elephant is $\frac{52900}{2920} \frac{N}{cm^{2}} \\$

$= 18.11\frac{N}{cm^{2}}$

Hence, option B is correct answer

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

Akimi4 [234]

Explanation:

<u>Succession </u>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.
