Answer:
Model B
Explanation:
It let's more fluids flow through unlike Model A
1/4. Make a Punnett square and plug in the two heterozygous genotypes of the parents, put them together and you get the following possible genotypes: AA, Aa, Aa, and aa. One of those is homozygous dominant. 1/4 or 25 percent.
Answer:
Explanation:
This is an example of a mixture which can be separated with simple separation techniques based on the physical properties of the mixtures.Magnetism, and filtration and evaporation
Iron is a magnetic material,but salt and sand are not,Therefore,the iron can be separated from the mixture with the use of magnet.
Salt and sand are mixable.But salt is soluble in water,but sand is not.Therefore by adding the sand and salt to water,the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through,while restricting the sand.
The sand would be removed by the filter paper,while solution passes through.
The salt solution and some sand residues is placed in evaporating dish and heated at low temperature. The water from the solution evaporates,leaving the salt behind.
Earthquakes occur all the time all over the world, both along plate edges and along faults. Most earthquakes occur along the edge of the oceanic and continental plates. The earth's crust (the outer layer of the planet) is made up of several pieces, called plates. The "Ring of Fire", also called the Circum-Pacific belt, is the zone of earthquakes surrounding the Pacific Ocean- about 90% of the world's earthquakes occur there.
Plants help the environment (and us!) in many different ways:
plants make food
plants make oxygen
plants provide habitats for animals
plants help make and preserve soil
plants provide useful products for people
plants beautify
