Eukaryotic organisms have membrane-bound organelles. Which of these organelles is considered the "control center" and stores the genetic material for the cell?
What is the nucleus?
The process in which parent cells produce daughter cells with the same number of chromosomes as the parent cells
What is Mitosis?
The process moves molecules other than water from an area of high concentration to low concentration.
What is Diffusion?
Ribosomes, endoplasmic reticulum, golgi apparatus and the nucleus. All of these organelles are involved in this process.
What is Protein Synthesis?
The crab Lybia tessellata carries a pair of sea anemones on its claws. The crab uses the sea anemone’s stinging tentacles as protection and the sea anemone obtains small food particles released by the crab as it feeds. This is a symbiotic relationship.
What is mutualism?
Placing wilted lettuce in cold water will make it crisp again. Which statement best describes what happens to restore the lettuce to its original condition? A Water left the lettuce cells by diffusion. B Water entered the cells of the lettuce by osmosis. C Osmosis caused salts to enter the lettuce cells. D Salts in the leaf caused water to leave the cells.
What is B?-Water entered the cells of the lettuce by osmosis.
This process occurs in the nucleus and produces a molecule of mRNA
What is Transcription?
If a raisin is placed in this solution it will take on water and grow larger. This is the type of solution it was placed in.
What is a Hypotonic solution?
In which way are photosynthesis and cellular respiration different? A Cellular respiration stores ATP, while photosynthesis releases ATP. B Cellular respiration produces oxygen, while photosynthesis uses oxygen. C Photosynthesis releases energy, while cellular respiration stores energy. D Photosynthesis uses carbon dioxide, while cellular respiration produces carbon dioxide.
What is-D?
The relationship that explains as predators increase, the prey will decrease - this will be followed by an increase in prey and a decrease in predator and the cycle will continue
What is Predator-Prey relationship?
This organelle is the site of aerobic cellular respiration in eukaryotic cells.
What is Mitochondria?
Hitchhiker’s thumb (H) is dominant to no hitchhiker’s thumb (h). A woman who does not have hitchhiker’s thumb marries a man who is heterozygous for hitchhiker’s thumb. What is the probable genotypic ratio of their children? (make a punnet square)
What is 50% Hh and 50% hh?
Which would most likely favor species survival in changing environmental conditions? A genetic recombination B energy involvement in gamete production C length of life cycle D number of offspring produced
What is A?
In humans, glucose is kept in balance in the bloodstream by insulin, and sweating keeps our bodies cool. This illustrates what mechanism
What is Homeostasis?
The correct sequence from most narrow to most broad of ecological levels of organization.
What is species, population, community, ecosystem, biome?
A sugar, a phosphate group, and a nitrogen base form a nucleotide which is the building block (monomer) of which organic compound.
What is Nucleic Acid?
Some flowers show incomplete dominance. If rr = white and R′R′ = red, which phenotypic ratio would be expected in the offspring of two pink flowers?
1 Red: 2 Pink: 1 White
Large molecules that require energy to move into the cell through the cell membrane would use this type of transport. Type and specific one.
What is Active Transport and Endocytosis?
Pollen in plants is most similar to which type of cell in humans?
What is -Sperm (gamete)?
Th eamount of energy available to the next level in the energy pyramid.
What is 10%?
The organelle found in a prokaryote.
WHat is teh Ribosome?
A diploid cell contains 2 pairs of homologous chromosomes Ss and Tt. Due to independent assortment these are the possible gametes produced by this organism?
A SsTt B Ss, Tt C S, s, T, t D ST, St, sT, st
What is ST, St, sT, st?
Change over time
What is Evolution?
These proteins speed up the chemical reaction and lower activation energy.
What are enzymes?
These form the bottom of the food chair or energy pyramid.
What are producers/autotrophs?
