33. In an eighth-grade science class, there are four lab groups. Group 4 designs an experiment to find out how light affects the germination rate of radish seeds. The students in Group 4 write out their
procedure and conduct their experiment. They discover inconsistencies in their data and decide to
increase the number of trials to obtain multiple data sets. Which of these most accurately describes how
this should be done?
A. Group 4 should repeat their procedure multiple times.
B. Group 4 should repeat a revised procedure multiple times.
C. Group 4 should communicate their procedure to another group for replication.

organisms that lack symmetry are called asymmetrical and belong to phylum porifera/sponges.

organisms with specialized stinging cells belong to phylum cnidaria. stinging cells are called cnidoblast cells.

cnidarians show two morphological forms : polyp (sessile) and medusa (mobile)

filter feeding is observed in porifera members.  

alternation of generation is observed in coelenterata or cnidaria. there is alternation of asexual polyp form and sexual medusoid form. it is also referred as metagenesis.

c. is the correct answer

true

explanation:

the answer to the blank provided is “an autosomal gene that is required for the expression of genes on the x chromosome”.

testis-determining factor, abbreviated as td, which is more popularly known as sex-determining region y or sry protein, is a dna-binding protein or  gene-regulatory protein/transcription factor, encoded by the  sry gene. it is the gene responsible for the initiation of male gender determination in humans.
