Fun facts about plant and animal cells
Reil [10]
Some fun fact to me is that you can compare the cell to a factory - I always found it interesting. So the nucleus would be like the CEO, and the  Endoplasmic Reticulum (ER) is like an assembly line - it's actually quite similar to a line like this!. And Ribosomes are the workers on this line.

6. Los seres humanos producen desechos celulares que salen del cuerpo gracias a diferentes procesos de los cuales están a cargo
sp2606 [1]

Answer:

D. Sistema reproductor.

Explanation:

La excreción es el proceso de eliminar los desechos y el exceso de agua del cuerpo. Estos desechos pueden ser dañinos y pueden causar daños.

Los órganos responsables de la excreción son el riñón, los pulmones, la piel, el hígado y el intestino grueso.

La piel elimina el sudor, el exceso de agua y las sales a través de las glándulas sudoríparas.

El sistema urinario está formado por riñón, uréteres, vejiga y uretra. El riñón elimina el exceso de agua y sal al producir orina que luego se transporta con la ayuda de los uréteres, la vejiga y la uretra.

En el sistema respiratorio, los pulmones excretan sustancias gaseosas, como dióxido de carbono y agua.

Another mutation in the MYBPC3 gene that can cause HCM is a change from an arginine at position 403 of the protein to a glutamin
Darina [25.2K]

The position within the original arginine codon where the point mutation most likely occurred was the second nucleotide. In this case, the mutation was CGA  >> CAA.

<h3>Mutations and codons</h3>

A mutation is any alteration in the nucleotide sequence of an organism.

A point mutation is a single base substitution that doesn't change the open reading frame of a given protein.

In this case, the CGA codon encodes for Arginine, whereas the CAA codon encodes for Glutamine, thereby the mutation likely occurred in the second base (C<u>G</u>A  >> C<u>A</u>A)
