Answer:
The answer is C, 40,000.
Explanation:
You can obviously tell that 400 is too low... that's one meal for all of the turtles! They would need 40,000 minnows because it's a stable number. They can reproduce, and keep the population up. 4,000, though, is too low because they wouldn't have enough time to reproduce and continue to keep the population alive. Therefore, 40,000 should be a stable population.
Decomposers break down dead organisms and other organic wastes and release inorganic molecules back to the environment. Food chains and food webs are diagrams that represent feeding relationships. They model how energy and matter move through ecosystems
Answer 1: Difference b/w wet and dry earwax genes is due to switch of a single DNA unit i.e. single nucleotide polymorphism.
Answer 2: Earwax is important in many ways mainly it is a biological flypaper as it prevents dust and insects from entering the ear.
Answer 3: Genetics have proved that for those who sweat a lot and have armpit odor have wet earwax.
Answer 4: The wet type earwax is dominant one with honey brown or dark brown color while dry one is recessive.
Answer 5: As wet earwax is dominant trait, according to the given scenario the genotype of parent with wet earwax will be "WW" which when crossed with dry earwax parent will have all the offsprings with wet earwax.
Answer:
True.
Explanation:
The life of a plant alternates between haploid and diploid generations. From a fully matured diploid plant (2n) which is known as sporophytic generation a lot of spores which are haploid are produced by the process of meiosis. By the process of mitosis, these spores then develop into new multi-cellular plant which is also haploid just like spores (n), this phase of plant life cycle is known as gametophytic phase. This haploid plant is capable of producing gametes (n) which are also haploid. When two such gametes from the same or different plant fuse with each other a diploid cell is produced which is known as zygote (2n). This zygote subsequently divides and grows into a diploid plant which is a part of sporophytic generation. This is how the entire life cycle of various plants alternate between gametophytic and sporophytic phase.
This diploid plant then later again produces spores and the cycle of reproduction goes on in the same manner as described above.
