By effectively liquefying the prey, this procedure helps facilitate digestion.What are the functions of echinoderms highlighted in Sea stars? Like other echinoderms, Sea stars are radially symmetrical with pentamerous radial symmetry, coelomate, triploblastic and have organ-system level of organization.Pedicellariae are present.Calcareous endoskeleton made of ossicles is present that gives them a spiny appearance.Water Vascular System is present which is the most distinctive features of echinoderms.learn more about echinoderms- https://brainly.com/question/13048917

Explain why it is very important for the gametes to divide by meiosis. What could happen if the gametes accidentally divide by mitosis? can someone answer in a sentence!!
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
Explanation: Gametes are made via meiosis which produces cells with n=23 instead of diploid cells. If gametes were produced instead by mitosis each gamete would be diploid not haploid.

Answer:
proteger el medio ambiente mediante la utilización de energías renovables, crear conciencia a través del uso sustentable de los recursos naturales, disminuir el consumo, reciclar y fomentar la utilización de compuestos biodegradables
Explanation:
La cultura del descarte en conjunción con el aumento creciente en la población mundial ha conducido a graves problemas ecológicos que afectan actualmente a la sociedad tales como, por ejemplo, el cambio climático, el cual plantea una preocupación muy seria acerca de las condiciones en las que recibirán nuestro planeta jóvenes y futuras generaciones.

how did the frame shift change the amino acid
During translation, the sequence of codons is read in order from the nucleotide sequence to synthesize a chain of amino acids and form a protein.
Therefore, frameshift mutations result in abnormal protein products with an incorrect amino acid sequence that can be either longer or shorter than the normal protein.
