Tasya [4]

Answer: Every stable population has one or more factors that limit its growth. A limiting factor determines the carrying capacity for a species. A limiting factor can be any biotic or abiotic factor: nutrient, space, and water availability are examples. The size of a population is tied to its limiting factor.  The environment, what food is there and what predators live there. How much food they get and if they are decreasing from weather, predators etc.

is Earth an open system or closed system? Explain your answer and provide at least one example that occurred during the Precambr
Ivan

Answer:

The Earth is essentially a closed system; it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero. Isolated systems can exchange neither energy nor matter with an outside system.

The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period. It is now known, however, that life on Earth began by the early Archean and that fossilized organisms became more and more abundant throughout Precambrian time.

s344n2d4d5 [400]

OPTIONS:

a. When there are just two other people at the party.

b. When everyone is wearing a nametag.

c. When there are more than 50 people attending the same party.

d. When the need for help from the person who is having a heart attack is very clear

Answer:

c. When there are more than 50 people attending the same party.

Explanation:

Bystander effect is a term used in social psychology to describe the tendency of an individual to intervene in the event of an emergency to offer help to the person needing it, when others are present at the scene of the emergency.

In the case of an emergency just like the scenario stated in the question, where someone develops a heart attack at a dance party, if the party has more people, the slimmer the chance of the person getting help from any of the 50 people at the party, as the presence of others would tend to discourage the any individual from attempting to help the victim having the heart attack.

The situation that would more likely show the bystander intervention effect is <em>"c. When there are more than 50 people attending the same party."</em>

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
