How are contractile vacuoles different then types of vacuoles?
Contractile vacuoles are formed when a food particle is engulfed. Their size depends on the size of food particle. They are not predefined. Other vacoules are predefined and exist whether the food particles are present in them or not.
What size buttonhole is needed for a button with a circumference of 7.38 centimeters Use the value of 3.14 to represent pi?
for a button to fit through its buttonhole, the hole needs to be the size of the button's diameter. what size buttonhole is needed for a button with a circumference of 9.42 centimeters?
What is bioaccumulants?
Bioaccumulation is the building up of toxins in a food chain. Since toxins like, for instance, DDT, are not soluble in water and are instead stored in the fatty tissues, their levels raise each tier you go up on the food chain. I'll give you an example...Plankton, at the bottom of the food chain, eat small particulates and algae, but also take in small levels of mercury.Small fish then eat the plankton. The mercury concentrates further - remember, DDT and mercury are not water soluble toxins, so they can't be passed through urine or feces.Large fish may eay up to 1,000 small fish in their lifetime. The mercury reaches dangerous levels for humans, and may cause genetic mutations in the fish's reproductive habits (ie, size of eggs, number of eggs, etc).Oceanic birds eat large and small fish. The mercury causes more genetic defects, including thinner eggshells.As you can see, bioaccumulation poses a real danger to certain ecosystems, especially since many areas were sprayed with DDT in the 60's and 70's.
Example of density dependent factor?
predation, availability of food, disease, parasitism Things that depend on the size of the population, as opposed to density independent factors such as weather, and natural disasters.
How does dwarf broiler parent helps in commercial chick production?
This is because dwarf broilers are small in size and therefore they need less space and food. Therefore it helps to reduce the cost of poultry farming
When adding vector in one dimension what could the position of the head of the arrow represent?
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.
When adding vectors in one dimension what could the position of the head of the arrow represent?
An Arrow can be used to represent a vector by having the direction of the arrow indicate the direction of the vector and the size or length of the arrow represent the size of the vector.
What is meant by magnitude of force?
A force is a vector - in two dimensions, you can represent it on paper as an arrow. Such vector/arrows have a size, and a direction. The size is usually called the "magnitude".
Is the komodo dragon at the top of the food chain?
Komodo dragons are at the top of any food chain. They are an apex predator because of their size, strength, and poison.
How is the size of an organism related to its position in a food chain?
generally: larger organisms are higher on the food chain as they have more ability to consume/chase/hunt/forage, etc.
Why is the insect second to the bottom on a food chain?
Because of their small size, insects cant really defend themselves that much. Therefore, making them second to last on the food chain.
What is the greatest number of links a food chain could have?
It depends on the length of the chain and the size of the links. A chain as a unit of measure is 66 feet long. Four rods equals one chain. A link is 0.04 rod, or 7.92 inches. There are 100 links in a chain.

A vector is represented by an arrow What is the significance of the length of the arrow?
The length of the arrow signifies the magnitude or size of the vector.
What does the size represent?
Size of what?
How are the size and directions of a force represented?
A force can be represented by an arrow in which the size of the force is represented by the length of the arrow (on some artbitrary but defined scale) and the direction of the force is the diretion of the arrow.
What effect would a drop in the size of the of the krill population have on the Antarctic food web and why?
Euphasia superba, Antarctic krill, are the base of the food chain in the Southern Ocean that surrounds Antarctica.Any decline in their population would mean that the remainder of the food chain would be forced into warmer water to find food.
