It is possible to determine whether the allele for curled ears is dominant or recessive by performing a test cross. It is fundamental for breeders because desired traits show differential patterns of inheritance.
In a diploid (2n) organism, a given gene locus exhibit two different variants or forms called 'alleles'.
An individual is homo-zygous when both alleles for a given gene locus are the same, while an individual is heterozygous when alleles are different.
In cases of complete dominance, the expression of the recessive allele is completely masked in heterozygous individuals.
A breeder is a professional who performs genetic crosses between different organisms in order to obtain offspring (eg., plants, animals, etc) with desired phenotypic features.
A test cross is a type of cross that breeders use to determine whether an allele is dominant or recessive (in this case, the allele for curled ears).
In a test cross, the organism that is a carrier of the unidentified allele is crossed with another organism that is believed to be homo-zygous for the recessive trait, and then the proportion of offspring is examined.

True or false. Every living organism on Earth has been classified.
Answer:
False
Explanation:
We know more of the moon than we do of our own oceans! There are many, many, organisms on Earth that have not been classified. We have not been able to explore deep in the ocean, extremely cold climates, and some may have even been missed in "our backyard" because Earth is so diverse! According to National Geographic, "Even after centuries of effort, some 86 percent of Earth's species have yet to be fully described, according to new study that predicts our planet is home to 8.7 million species. ... So far, some 1.2 million species are known to science."

A rise in __________ released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires __________ energy.
A rise in CALCIUM released from the sarcoplasmic reticulum allows actin to bind to myosin and cause a contraction, which requires ATP energy. ATP is the energy coin of the cell.
Adenosine triphosphate (ATP) is the energy coin that cells use to carry out many metabolic reactions (e.g., reproduction, motion, differentiation, etc).
The sarcoplasmic reticulum is an organelle located inside muscle cells similar to the smooth endoplasmic reticulum.
This organelle (sarcoplasmic reticulum) acts to store calcium which is required during muscle contraction.

Biotic and abiotic organisms coexist, interdependent organisms that share the same habitat. Through different processes such as predation, symbiosis, parasitism, they will disintegrate and reform to give themselves the energy and nutrient cycle.
The relationship that occurs between the community and its environment will be a flow of matter and energy in the ecosystem. There will also be different types of ecosystems such as marine, terrestrial, microbial and artificial. In all of these there will be food chains between the different species.
