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? A. The nucleus produces large amounts of tRNA for ribosomal proteins
B. The nucleus produces large amounts of rRNA and sends it to the cytoplasm
C. Ribosomes floating in the cytoplasm exceed the amount of available mRNA
D. Ribosomes floating in the cytoplasm not bound to mRNA bind to the endoplasmic reticulum

Mario performed an experiment to determine if photosynthesis was affected by the amount of light that a plant received. what could he have done to increase the validity of his data? reduce the number of plants. remove the 1 hour group. add a 0 hours control. measure the oxygen in liters

In eukaryotes, genetic information is passed to the next generation by processes that include mitosis or meiosis. which of the explanations identifies the correct process and supports the claim that heritable information is passed from one generation to another? a. mitosis, followed by cytokinesis, produces daughter cells that are genetically different from the parent cell, thus insuring variation within the population. b. during mitosis, dna replication occurs twice within the cell cycle to insure a full set of chromosomes within each of the daughter cells produced. c. in asexual reproduction, a single individual is the sole parent and passes copies of its genes to its offspring without the fusion of gametes. d. single-celled organisms can fuse their cells, reproducing asexually through mitosis to form new cells that are not identical to the parent cell.
