Answer:
Sea urchins have a unique relationship of oxygen and carbon-di-oxide.
Explanation:
Sea Urchins spread oxygen in a unique way. They take in oxygen by staying inside water. Oxygen enters the body through their gills and tubed feet. CO2, which is waste is released through the anus. They get oxygen only through diffusion, i.e. diffusion of oxygen into the organism. Oxygen diffuses in body through the canals and carbon dioxide diffuses back into the canals. Urchins also have the capability to cope up with rising CO2 levels in the sea.

Answer:
c. 10°C
Explanation:
Given that: A slice of pizza has 500 kcal.
That is to say Q = 500kcal
If the pizza was burned and all the heat were used to warm a 50-L container of cold water,
what would be the approximate increase in the temperature of the water?
We were also being told to note that; A liter of cold water weighs about 1 kg.
i.e 50-L container weighs about 50kg (mass)
∴ Since;
Q= 500kcal,
m = 50kg; &
the specific heact (c) = 1
we can find the approximate increase in the temperature of the water by using the formula:
Q = mcΔT
ΔT = 
ΔT = 
ΔT = 10°C
Answer:
The companies take away the bottle as "security deposit and however they can recycle and reuse it."
Explanation:
When buying different beverages from a person distributing, a deposit needs typically to be paid to the distributor from the containers that have been taken. However, the distributor will issue a refund once the bottle that was taken has been returned to the place of purchase. Therefore, the distributor will reimburse the redemption of the retailer the amount that was deposited for every container. The additional handling fees usually added in some countries. The deposits that remain unredeemed are taken to the state or kept by distributors.
