A heart cell taken from a rat and placed in Flask A with a nutrient-rich culture medium produced heart cells after 24 hours.
A kidney cell taken from the same rate placed in Flask B with a similar nutrient-rich culture medium produced kidney cells after 24 hours.
The best explanation is:
INFORMATION DICTATING CELL TYPE IS PASSED FROM PARENT CELL TO OFFSPRING DURING MITOSIS.
Hi, The center image is a decomposer because it decomposes the dead organisms. The grass is a producer since it produces its own energy through photosynthesis. The rest are consumers because they consume other organisms to get energy. Hope that helped!
Answer:
The correct answer would be - nitrficiation, denitrification, nitrogen fixation, and decomposition.
Explanation:
Thiobacillus denitrification is a facultative, obligate chemolithoautotrophic anaerobic bacterium that is well known for its ability to couple the oxidation of inorganic sulfur-based compounds to denitrification.
The name of the bacterium is derived from its function or the metabolic ability as it performs denitrification on thio (sulfur) based inorganic compounds by the process of oxidation. This process helps in bioremediate groundwater by these processes of nitrogen fixation by oxidation of inorganic compounds of sulfur.
Thus, the correct answer is - nitrification, denitrification, nitrogen fixation, and decomposition.
Question: Jezelyn needs to create a project that shows reproductive isolation in action and decides to make a video. Which of the following would make the best project?
a video that shows a large river that has penguin populations on both sides
a video that shows penguin species that have different mating dances a video that shows
a penguin that is laying eggs a video that shows penguins in a tidal pool and an open ocean
Answer:
The right option is a video that shows penguin species that have different mating dances.
Explanation:
Reproductive isolation is the inability of animals of closely-related species to interbreed with one another successfully as a result of various differences which can be ecological, behavioral, psychological, or genetic. From the question given above, the difference in the mating dances of the penguin species will not allow the animals to unite and mate. This condition describes reproductive isolation. Reproductive isolation is caused by mating differences, sterility or environmental barriers that eventually lead to the adaptive splitting into two species. However, reproductive isolation is not sufficient but internal barriers to gene flow are required for speciation to evolve.
The relationship in human hair alleles is that of incomplete dominance whereby allele of a specific trait is not fully expressed over it paired allele. By crossing any two wavy haired humans all the air type which is obtained is hairy. Crossing straight haired and wavy-haired man will produce one curly is to one straight is to one wavy. She is faithful.
