Answer:
Explanation:
The key difference between protostomes and deuterostomes is the fate of the blastopore during their embryonic development. The blastopore in a protostome develops into a mouth, where as the blastopore in deuterostomes develops into an (a n a l) opening.
Protostome- Blastopore develops into a mouth. Spiral, determinate cleavage. Schizocoelous formation of the coelom. Annelids, mollusks, and arthropods
Deuterostome- Blastopore develops into an anus. Indeterminate cleavage. Radial cleavage pattern during early development. Echinoderms and the chordates.
Both- Distinct evolutionary lines of coelomates. Complex skeletons that allow them to be highly mobile. Bilateral symmetry. Triploblastic.
Explanation:
A skeletal muscle generates the greatest tension when it is: partially stretched before being stimulated
Ever cell has a gene code that's exactly the cell but some don't use that dba strand because specific parts need specific DNA
But an egg or sperm only has one. That one is chosen at random, through a process called meiosis. When meiosis messes up, you can end up with to many or too few chromosomes. One extra chromosome in a egg or sperm means three in the fertilized egg and so trisomy.
Se denomina “energías renovables” a aquellas fuentes energéticas basadas en la utilización del sol, el viento, el agua o la biomasa vegetal o animal -entre otras-. Se caracterizan por no utilizar combustibles fósiles –como sucede con las energías convencionales-, sino recursos capaces de renovarse ilimitadamente.
