To separate the pebbles you should hand pick it,
meaning-from the word itself, you don’t have to use any kind of instrument but
your hand.
On the other hand, to separate the mud you can use
decantation or sedimentation or filtration.
To separate the husk you have to use sieving.
Many plants depend on animals primarily insects for pollination and sexual reproduction. If the animals (insects that pollinate) most flowering plants would be unable to reproduce and would go extinct.
Both plants and animals undergo cellular respiration producing Carbon Dioxide. Animals produce only Carbon Dioxide while plants produce both Carbon Dioxide and Oxygen. If animals went extinct there would be less Carbon Dioxide to support photosynthesis and more complex plants would have a difficult time adapting to the reduced levels of Carbon Dioxide.
Plants that survived the extinction of animals would be much simpler than presently complex plants.
Perhaps some plants would become predators of other plants to absorb the nitrogen content of other plants because of the lack of animals to engage in the recycling of nitrogen content.
Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
I believe the answer is choice D. Hope this helps!!!
