Graphite is well known to be pencil lead - You might actually learn this in Chemistry/Physical Science like we did!
Charcoal & coal you cannot use - you could but it'd be difficult and irritating.
Fullerene is the third form of carbon. It can be used for electronics AND medicine. Amazing right??
The organism can produce 12 genetically different gametes.
<h3><u>Explanation:</u></h3>
The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.
Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.
Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.
So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
Answer:
C. Cheaper than producing electricity from coal oil gas.
Explanation:
Nuclear plants and energy has been proven to be cheaper than most, Low fuel costs have from the outset given nuclear energy an advantage compared with coal and gas-fired plants. Uranium, however, has to be processed, enriched and fabricated into fuel elements, accounting for about half of the total fuel cost.
Respiration occurs when glucose<span> (</span>sugar<span> produced during photosynthesis) combines with </span>oxygen<span> to produce useable cellular energy. This energy is used to fuel growth and all of the normal cellular functions. </span>Carbon dioxide<span> and water are formed as </span>by-products<span> of respiration.</span>
Answer:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis.
Explanation:
The pairing of homologues at the beginning of meiosis I ensures that each gamete receives one member of each pair. The pairing of homologues brings together the near-identical sequences found on each chromosome, and this sets the stage for crossing over.Following crossing over, at least two of the four chromatids become unique, unlike those of the parent.The frequency of recombination is not uniform throughout the genome. Some areas of some chromosomes have increased rates of recombination, while others have reduced rates of recombination . Recombination or crossing over occurs during prophase I. Homologous chromosomes – 1 inherited from each parent – pair along their lengths, gene by gene. Breaks occur along the chromosomes, and they rejoin, trading some of their genes. The chromosomes now have genes in a unique combination.Independent assortment is the process where the chromosomes move randomly to separate poles during meiosis. A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes.
This reshuffling of genes into unique combinations increases the genetic variation Slightly different sequences in the genetic code of different individuals from the same species. This is important for species adaptation to occur in a population and explains the variation we see between siblings with the same parents.
