The inside surface area is shaped in a crescent. It consists of a spiral valve which is made up of the small intestine. Although the dogfish shark has a relatively short small intestine compared to other animals, therefore, the spiral valve allows for a more compact form of the small intestine.
Hence, this structure provides maximum surface area over a relatively short distance in order to make the absorption of nutrients efficient achieved from the food, the sharks had from eating different sea animals.
I think 75% or 90% (I looked it up lol)
Humans can will themselves to eat more, as we know that food comes easy to us.
Animals, on the other hand, top priority is survival, so they usually wouldn't think about eating more because it just "tastes good."
Single-cell RNA-sequencing (scRNA-seq) provides the chance to analyze heterogeneous cellular compositions and probe the patterns of gene expression that are unique to each cell type under various circumstances. However, batch effects like lab setups and individual variability make it difficult to use them in cross-condition designs.
<h3>What is Single-cell transcriptomes ?</h3>
In single-cell transcriptomics, the messenger RNA levels of hundreds to thousands of genes are simultaneously measured to assess the degree of gene expression in individual cells within a particular population.
<h3>Advantages : </h3>
• Integrated protocol proceeds directly from whole cells and preserves sample integrity.
• High resolution analysis enables discovery of cellular differences typically hidden by bulk sampling methods.
• Robust transcriptome analysis down to single-cell input levels for high-quality samples.
