Answer:
Introduction Purpose: Explore the interdependence of organisms by
performing an experiment with lima bean plants and earthworms. Question: How can the presence of one species benefit another in
the same ecosystem?
Hypothesis: If plants grow in soil containing worms, then the
plant growth will be greater, because worms help decompose organic matter and distribute it through the soil in a form that plants can use.
Explanation:
<span>The opossum is the only marsupial found on North America. It is found in many locations and is fairly commonly seen rummaging through waste and other leftover areas looking for things to scavenge. Opossums are known for taking any opportunity it can to find waste products and eat them.</span>
Some plants also have large leaves to soak up nutrients and water, very helpful in this biome since it rains a lot. - Having some needles cased in wax, withstand cold temperatures and losing water from their leaves. - Having thin bark and shallow roots enables trees to withstand fire.
In this case, the black body colour is the dominant one. The white dog is homozygous recessive.
As the cross between the black female 2 and the white male results in all black pups. This means that the all the offsprings are heterozygotes and the Female 1 is homozygous recessive having a BB phenotype (where B codes for dominant allele).
As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).
