About this Exam
Prepare with the 5005 Blue Notes Practice Test practice quiz. This question bank includes 10 questions covering genetic, reproduction, result, diversity, and parents. Use it to review important concepts, identify knowledge gaps, and build confidence for the related exam, course, or assessment.
Sample Questions
Question
1
Which part of a cell makes protein?
Explanation:
Proteins are built by ribosomes. These molecular machines translate the genetic message in mRNA into a chain of amino acids, forming a polypeptide that folds into a functional protein. Ribosomes can float freely in the cytoplasm or be attached to the rough endoplasmic reticulum, where they synthesize proteins destined for secretion or membrane insertion. Lysosomes break down waste and old organelles. The endoplasmic reticulum is a site for protein folding and processing and, in the rough part, for synthesizing many proteins, but the actual assembly of amino acids into a protein happens at the ribosome. The Golgi apparatus then modifies, sorts, and ships proteins that were made elsewhere in the cell.
Question
2
Gas giants true statement?
Explanation:
Gas giants are planets whose mass is dominated by gaseous envelopes rather than solid rock. The defining feature is that their atmospheres are mostly hydrogen and helium, which is why the best statement describes them as primarily made of these two light elements. This composition gives them very thick, deep atmospheres and strong gravity that can hold onto these gases, rather than a solid surface like rocky planets have. They do not have solid surfaces accessible to standing on, and they are located far from the Sun in the outer solar system, not close to it. So, the hydrogen-and-helium dominance best captures what a gas giant is.
Question
3
Approximately how many days does the Moon take to revolve around the Earth?
Explanation:
The Moon’s motion around Earth is best described by its sidereal month, which is about 27.3 days. This is the time it takes for the Moon to return to the same position relative to distant stars. The longer ~29.5-day cycle you might have heard of is the synodic month, the cycle of the Moon’s phases, because Earth is moving around the Sun as the Moon orbits, so it takes a bit longer to catch up in the Sun-Earth-Moon alignment. So, approximately 27 days is the orbital period around Earth. The other options don’t reflect the actual orbital period.
Question
4
Does sexual reproduction result in genetic diversity?
Explanation:
Genetic diversity comes from the way genetic material is shuffled and combined in sexual reproduction. Gametes are produced by meiosis, which includes crossing over and independent assortment. Crossing over exchanges chromosome segments between paired homologs, creating new allele combinations. Independent assortment randomly distributes maternal and paternal chromosomes into gametes, producing many possible genetic combinations. When two gametes fuse during fertilization, the zygote gets a unique mix of genes from both parents, and even siblings end up genetically different. This mixing means offspring are not identical to their parents or to each other, which is the essence of diversity in sexually reproducing populations.
Question
5
What process leads to new combinations of DNA when two different parents contribute genetic material during reproduction?
Explanation:
Genetic variation in offspring comes from the mixing of DNA from two parents during reproduction. This variation is created by meiosis, the special cell division that produces gametes with different allele combinations thanks to crossing over and the random assortment of chromosomes. When two gametes fuse during fertilization, the resulting zygote carries a new mix of DNA inherited from both parents, giving the next generation inherent genetic diversity. Mitosis, by contrast, is the regular cell division that creates identical somatic cells and does not introduce new allele combinations. Cellular respiration and photosynthesis are energy-related processes and do not generate inherited DNA variation.
