Answer:
Bacteroides plebeius which is present in the gut humans have the same genes to marine bacterium Zobellia galactanivorans.
Explanation:
many researchers findout that bacteroides plebeius acquired functional porphyranase and agarase genes from a marine bacterium called Zobellia galactanivorans. Zobellia galactanivorans is a marine bacterium which has the ability to digest complex polysaccharides such as agarose and porphyran. so due to similar genes, Bacteroides plebeius also digest polysaccharides such as agarose and porphyran present in sea weed.
It was believed that the magnetic field to be generated deep down in the Earth's core. But the truth is the flow of liquid iron generates electric currents, which produces magnetic fields.
But the truth is no one really knows for certain so the only thing we know is that the spin of the earth is the cause of its magnetic field
Hope this helped :)
Have a great day
Answer:
50% of their children are likely to be carriers of cystic fibrosis
Explanation:
Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.
Hello there
So Ecosystem is a natural process with natural resources and abiotic factors such as sunlight, soil, water and all nonliving things
Components of the ecosystem are the abotic factors that biotic factors which are living things.
