What stars are cool and bright stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
Why do tapeworms have flattened bodies with a large surface area?
This is because they need to fit in anything!
Why does a sperm cell need large surface area?
A sperm cell needs a large surface area to maximize contact with the egg cell during fertilization. This allows for efficient transfer of genetic material and increases the chances of successful fertilization.
Why is it that when an object is slid from a area with a large surface area to one with a smaller surface area the force needed to move the object remains the same?
It doesn't necessarily. The parameters of the experiment need to be more thoroughly defined.
What are bright cool stars?
To be bright you need to be hot, close or have a large surface area. The brightest coolest stars are red super giants. They have such a large surface area, that even though their surface temperature is cool - in star terms - their large surface area makes them appear bright.
What is a real world example of surface area?
A practical need to calculate surface area arises, for example, when you need to paint your house. The amount of paint you need is proportional to the surface area you want to paint.
How does a large surface area help the function of a system?
A surface is where things happen between what is on one side of the surface and the other. Thus in general if you want more of these happenings (eg gas exchange) you need the biggest possible surface area. If however you want to minimise these happenings (eg heat loss) you try and reduce the surface area.
Why do adult orangutans need a large area of forest to survive?
They need a large area because they get in groups and usually have large familys or large packs.
Explain why large active organisms need special surface for exchange?
large organisms need larger area to exchange more substances.but large organisms have small surface area to volume ratio.this means that the surface is not large enough to enable gases and nutrients at the fast rate needed to keep all the cells alive.thus large organisms need special exchange surfaces to provide the body with the nutrients and gaseous exchange they require.
What is the relationship between a cells surface area and volume?
The relationship is usually expressed as a ratio: surface area divided by volume. Small cells have a large surface area to volume ratio, whilst large cells have a much smaller value. This is important because the cell absorbs the things it needs, and gets rid of what it doesn't need, through the surface. If the cell gets too large, not enough exchange can take place to keep the cell going, so there is a natural limit on the size to which a cell can grow.
How do you find the surface area of a rectagle?
to find the surface area of the triangle we just need to multiply the length with breath. area=lengthXbreadth
