An ovarian cell receives a series of endocrine signals from the pituitary gland to start producing hormones at a cytoplasmic receptor protein. These hormones also have cytoplasmic receptors. To accommodate this increase, the ovarian cell starts to produce large amounts of mRNA. Which of the following would be observed as the cell produces more ribosomes?

The nucleus produces large amounts of tRNA for ribosomal proteins.

The nucleolus produces large amounts of rRNA and sends it to the cytoplasm.

Ribosomes floating in the cytoplasm exceed the amount of available mRNA.

Ribosomes floating in the cytoplasm not bound to mRNA bind to the endoplasmic reticulum.

Researchers pose the question: can shoe size be predicted from a woman's height? a random sample of 18 females and their shoe size versus height (in inches) gives the regression results shown in the table. predictor coeff se coeff t ratio p-value constant -45.74 32.58 -2.57 0.147 height 0.5943 0.2984 1.99 0.042 s = 3.2178 r-sq. = 18.9% r-sq. (adj) = 12.4% is there statistical evidence of a linear relationship between shoe size and height? no, because r2, the coefficient of determination, is too small no, because 0.147 is above any reasonable significance level yes, there is evidence at the 5% significance level yes, because, by any reasonable observation, taller women tend to have a larger shoe size
