It's like editing over what's already written. it's the process of reading something and marking for any error. (: Usually deemed more helpful when you let two completely different people proof read the same paper to get a better result!
Good luck, rockstar! (: I wish you the best and hope you pass!
Answer:
Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. ... In other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous ("hetero" meaning "different") for that allele.
When the cardiac muscle cell is at rest, the concentration of sodium and calcium is greater on the outside of the cell.
The resting membrane potential (the cardiac muscle cell is at rest) is characterized by more negatively charged inside of the membrane comparing to the outside. The main ions found outside the cell at rest are: sodium (Na+), and chloride (Cl−), and Ca2+ whereas inside the cell it is mainly potassium (K+).
NADP is the most abundant acceptor for hydrogen released in the Krebs cycle.
In a cornfield, only one plant species has dominated the area, that is the corn plant. While in a natural meadow, multiple species of plants occurs of different species. The presence of the different types of plants in the meadow will interact more number of insects in it as compared to the corn field. This will lead to more interactions among the different species in a natural meadow. The greater biodiversity of the natural meadow than the cornfield will support it better.
In case of any natural disaster, or a pest attack, all the plants will be killed in a corn field and so will the insects dependent on them, but in a natural meadow, if one plant species is killed by a natural disaster, other will still be alive. Hence, the ability to survive is greater in natural meadow.
