Answer: The shortcomings of the experiment design is what the universe has no known limit to which it can grow. As for a balloon when enough air is put in, it will pop.
Explanation:
Answer:
The cell membrane structure is very important because everything alive has cell membranes. The model used to describe the cell membrane is called the <u>fluid mosaic</u> model.
The right answer is 2 divisions.
Meiosis follows the replication of DNA from a reproductive cell (male or female). It allows the passage of a so-called diploid mother cell to 2n chromosome homologous chromosomes to 4 single-chromosome haploid daughter cells. For that it must pass by two successive divisions, the first division is reductionelle generating two diploid cells with n chromosomes. the second division is equational giving 4 haploid cells to n chromosomes from the two preceding cells.
Answer:
A. Lancelet
B. All chordates
Explanation:
A. Dorsal nerve chord is the only <u>unique feature</u> among all members of <u>phylum chordata</u> (mainly found in subphylum Vertebrata). In the given list, only lacelet is the Chordate whereas <u>snail belongs to phylum Mollusca</u>, <u>grasshopper belongs to Arthropda</u>, and <u>jellyfish belongs to Cnidaria</u>. Dorsal nerve cord runs along the length of organism's body.
B. <u>Gill slits</u> are <u>opening structures</u> to gills through which water passes from pharynx/throat to exterior. Their main purpose is to help filter the food particles available in surrounding water. Although they are typical for amphibians and fishes, chordates also possess gill slits at embryonic stages.
