Surface area affects the function of an organ in the human body...
In our lungs, there are balloon like structures called alveoli.if we spread our lungs it equals to 80m^2. this large surface area allows lungs to take as much as possible oxygen to carrry respiration so that life processes go on.

<h3>What is a scientific theory?</h3>
A scientific theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed.
A theory can also be described as a statement that sets out the laws and principles of something known or observed, in other words, a hypothesis confirmed by observation, experiment.
According to this question, the fact that all planets orbit around the sun in an elliptical path is a scientific theory because it has been tested and confirmed to be true.
Therefore, the statement that describes a scientific theory is as follows: Jose explained that all planets orbit around the sun in an elliptical path.

If i remember correctly they should be adenine (A), thymine (T), guanine (G) and cytosine (C). i hope this helps. sorry if they arent all correct.
Answer:
The correct answer will be option- synaptonemal complex.
Explanation:
The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.
The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.
Thus, option- synaptonemal complex is the correct answer.
