Answer:
See the answer below
Explanation:
<em>If pink eye is recessive, it means that the normal eye is the dominant trait. According to Mendelian law, the ratio of normal to pink eye in a cross involving two heterozygous mice should be 3:1</em>.
Chi-square = 
where O = observed frequency and E = expected frequency.
Phenotype Observed Expected Chi-square
Normal 18 3/4 x 20 = 15 
= 0.6
Pink 2 1/4 x 20 = 5 
= 1.8
Total Chi-square = 0.6 + 1.8 = 2.4
Degree of freedom = 2 - 1 = 1
Critical Chi-square value at 95% = 3.841
<em>The critical Chi-square value is more than the calculated value. </em><u><em>Hence, the observed number of offspring fits the expected number of offspring.</em></u>
The three structures found in plant cells that aren't found in animal cells are the cell wall, chloroplast, and the large central vacuole. The cell wall is a hard outer covering that allows plant cells to keep their shape. Chloroplast contain the pigment known as chlorophyll and allow plants to undergo photosynthesis. Finally, the large central vacuole is there to allow plants to store lots of water.
<span>Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back intocarbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, incellular respiration oxygen is combined with hydrogen to form water.</span>
