Ventilation systems are needed in a <span>multicellular organism to actually obtain oxygen and give out carbon dioxide. Without this ventilation system, it would be very difficult for multicellular organisms to survive. It has been also observed that surface diffusion is not enough for a multicellular organism to breath.</span>
Answer:
monoallelic gene expression
Explanation:
<em>Monoallelic expression is a type of gene expression where only a copy out of the two copies of a gene is expressed and the other is silent. </em>
A gene is usually represented by two alleles representing alternate forms of the same character. Individuals inherit an allele each from their two parents for every gene within their genomes.
When only one of the alleles is expressed for a particular gene while the other allele remains silent, such phenomenon is referred to as monoallelic gene expression.

Answer:
The correct answer is A. Tobacco mosaic virus
Explanation:
Virus can have DNA and RNA as its genetic material. Tobacco mosaic virus has RNA as its genetic material. Protein is not a genetic material because it is a product coded by genetic material.
So a hybrid can be made only when the genetic material of two different organisms is mixed not two different biomolecules. Therefore when RNA from the tobacco mosaic virus is mixed with the protein from a DNA virus the result would be a tobacco mosaic virus only.
Its cellulose....
hope it gonna work...✌️✌️✌️
