Answer: i hope that helps ^^

Explanation:

Emotions such as anger and hostility ramp up your "fight or flight” response. When that happens, stress hormones, including adrenaline and cortisol, speed up your heart rate and breathing. You get a burst of energy. Your blood vessels tighten.

Stress cardiomyopathy can occur in reaction to stressful news, such as a loved one's cancer diagnosis. And strong emotions, such as anger, may cause irregular heart rhythms. Stress can be harmful to your heart, too. If you are under stress, your blood pressure and heart rate go up.

It's affects ones mental health too leading to loss of concentration and irregular eating and sleeping habits

WINSTONCH [101]
The surface area will be:
S.A. = 6l²
S.A = 6(100 x 10⁻⁶)²

Volume = l³
Volume = (100 x 10⁻⁶)³

Surface area to volume ratio:
[6(100 x 10⁻⁶)²] / (100 x 10⁻⁶)³
S.A : Vol = 6 x 10⁴

A land developer and several ecologists are discussing how a parcel of private land should be developed with housing while savin
FromTheMoon [43]

Options for the question have not been provided. They are as follows:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.

C) The separate 1-hectare plots are less vulnerable to edge effects.

D) The large plot will create more inbreeding in many species.

Answer:

A) The single intact parcel would have a smaller amount of edge than the 20 separate parcels.

Explanation:

In the given case, 20 hectares of land has been allocated to natural habitat. This means that natural flora and fauna will flourish here without any human interference. In this situation it is better to have an intact 20 hectares area at one side of the land, rather than having 20 separately spread out 1 hectare areas. This is because having one large piece of land at one side will reduce the edge effect.

Edges occur where two different habitats meet. While edges can be beneficial when it comes to natural habitats because the boundary habitat increases overall biodiversity, it can be detrimental when the edges are due to human settlements. It will be difficult to avoid human interference as the natural habitats are scattered among human settlements. Each individual plot will also get less area due to which it will be difficult for all the species to accommodate comfortably. Many animals can venture out in search of food which can be dangerous to both animals and humans. It is better to have a big separate land at one corner so that everyone can survive peacefully.
