Answer:
Mitosis:
Mitosis has 4 stages total and produces 2 diploid daughter cells. The purpose of mitosis is for cellular proliferation. Since we only get 2 daughter cells, the chromosome number remains the same and generic variation doesn't occur.
Meiosis:
Meiosis has 8 stages total and produces 4 haploid daughter cells. In the shortest nutshell, meiosis is mitosis but twice. The purpose of meiosis is sexual reproduction. Since we get 4 daughter cells, the chromosome number is halved and generic variation does occur.
Answer:
Modified apocrine sweat glands
Explanation:
The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.
As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.
This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.
Answer:
C. The differences between the observed and expected counts are too large to be attributed to chance.
Explanation:
The p-value of the statistic represents the chance that the observed count is based on luck or chance. When p value too high, the research can't be used since the chance that its not represent real condition are too high. Most researchers use 5% (0.05) as the cutoff of something called statistically significant. In this research, the p-value is 0.04 or 4%, so it is statistically significant.
