The correct answer would be B) FALSE because secondary succession DOES NOT occur in ecosystems without soil.
X-linked recessive disorders require two affected (recessive) alleles Xb to express in the female, but requires (the) only one in the male.
Therefore there are no male carriers. A normal male has the XB allele, and the affected male has the Xb allele.
A female either has 2 XB alleles, in which case she is normal and not a carrier.
If she has XBXb alleles, then she is a carrier, but phenotype is normal.
If she has XbXb alleles, she will exhibit colour-blindness.
Since woman's father has colour-blindness and she has normal vision, she is a carrier, because she has XBXb alleles.
Her husband has normal vision, so he has (one) XB allele.
Here's the Punnett square
Mother XB (father)
XB XBXB (normal vision)
Xb XBXb (carrier)
We see that the XbXb (colour-blindness) case is missing, so the phenotype colour-blind is not expected (unless other medical conditions are present)
Answer:
B. New hydrogen bonds are formed, breaking the bond in the structure of the nucleic acid.
Explanation:
Nucleic acids are one of the four major biomolecules in living systems. They function to store and transmit genetic information in living organisms. Nucleic acids are polymers made up of NUCLEOTIDE monomeric units. DNA and RNA are the two nucleic acids in nature.
However, since the complementary nucleotide bases that make up nucleic acids interact together via HYDROGEN BONDS i.e. G-C, A-U, if new hydrogen bonds are formed, breaking the bond in the structure of the nucleic acid will disrupt the nucleic acid sequence
Answer:
At a point directly in the middle between the bottom and when the car stops. This is because this is the perfect balance point between kinetic energy and potential energy.
Explanation:
When it is in the middle it has the most potential to move
