Both the nitrogenous base and phosphate group are attached to the deoxyribose sugar in DNA.
Explanation:
Such an offspring would have the genotype YY, which are the dominant alleles that code for yellow colour in bananas.
In the Punnett's Square, none of the offspring have YY genotype. Hence the answer is 0%.

Answer:
recognizes a hormone’s chemical structure
Explanation:
In living systems, chemical messengers called hormones are secreted into the body via the bloodstream or ducts by certain glands called endocrine glands e.g pancreas, hypothalamus etc. These hormones are meant to effect a physiological change in certain cells called TARGET CELLS.
In biology, a target cell is any receiving cell that has the ability to respond to signals and messengers like hormones. This responding ability of hormones is due to the possession of specific receptor sites for the specific hormones. The receptor on a particular target cell recognizes that specific hormone's chemical structure, hence, will only respond to it.
For example, an insulin hormone secreted by the pancreas will only be responded to by a target cell that recognizes the chemical structure of the insulin protein using its receptor molecule.
The correct answer is - A strong wind blows across a Midwestern prairies.
An energy flow through a natural system is when we have no human interference or any man made objects in the process. A strong wind that blows across a Midwestern prairie is a nice example of this. We have a natural unmodified by humans environment through which a natural phenomenon is bringing energy flow. The energy flow will of course operate in different manner and have different effects compared to the ways in which the humans would have used it. The strong wind in the prairie will bring in lot of small particles, sediments, with its energy and deposit big portion of them in the prairie, thus making it more fertile.
