A plant cell is a type of eukaryotic cell that has many organelles working together to help the cell function smoothly. It has many of the same features as an animal cell, but has an extra structure for support. Answer and Explanation: ...
To answer the question, "The determines the shape of the cell and provides a strong structural support to prevent the bacterium from bursting or collapsing," we need to analyze the options provided and understand the functions of the structures menti
(n = 18) the derived state45,51. Overall, most chromosomes maintained their structure betweenPlatantheraandOphrys, but some major rearrangements are apparent, particularly with regard to chromosome fusions. Chromosome (chr) 4 inO. sphegodesappears to be the product of a fusion between chr ...
Population structure and relatedness To study the genetic ancestry data of 224,737 FinnGen participants that passed genotyping QC (Supplementary Methods, section 3), we combined the FinnGen data with 2,504 phase 3 reference samples from the 1000 Genomes Project5and used principal component analysi...
