El vidrio no templado contiene burbujas de aire microscópicas que se expanden y contraen a medida que el vidrio se calienta y enfría, especialmente a temperaturas extremas como durante el enlatado y la congelación. Cuando esas pequeñas burbujas de aire se expanden, hacen que el vidrio se rompa o incluso explote. Espero que esto haya ayudado, por favor, dé cinco estrellas y mentalmente.
The right options are;
A. radial symmetry
B. acoelomates
E. asexual reproduction
F. sexual reproduction
Cnidarian are organisms that belong to the phylum; Cnidaria. Almost all cnidarians are marine animals, and there are several species which include the corals, jellyfish, sea anemones, sea pens, sea fans, hydras, and sea whips. The body form of the cnidarian is radially symmetrical with their mouths covered by tentacles. Many species of cnidarians possess complex cycles of asexual polyp stages, while some reproduce sexually. Cnidarian have many modes of feeding which include; parasitism, taking nutrients from symbiotic algae within their cells, and predation.
A population is essentially just a collection of all living things in one category. People are one population, insects are another, etc. Communities are "more organized" populations. Soccer players hang out with soccer players, spiders hang out with spiders. We split into "our people" within our population.
I know that may be a little confusing, but if you have anymore questions feel free to ask. I hope I was able to help. Best of luck!
Answer:
Option a
Explanation:
Random selection or random sampling from a given population is the most appropriate way, especially in experimental studies. This method is simple and accurate. According to the above-mentioned case, if the researcher selects students randomly for the experimental and control group, then each of them would have an equal chance of selection. Hence, the results would be generalized and not biased.
Answer:
III. Equal number of chromosomes.
Explanation:
Comparison between two cells, one cell just before first meiotic division and other cell ready to start mitosis is that both the cells have equal number of chromosomes.
Both the cells have an equal number of chromosomes that is 2n (diploid), where n is 23 and total chromosomes are 46 in each cell but at the meiosis at the end meiosis produces four haploid (n) daughter cells and mitosis produces two diploid (2n) cells.
Hence, the correct answer is "III. Equal number of chromosomes.".
