Mitosis is only 1 division whereas meiosis is 2 divisions.
The answer is convergent boundary. This happens at subduction zones which are a type of convergent boundary.
Answer: Option B.
The heart senses an increase in blood pressure and secrete ANF to decrease blood pressure.
Explanation:
Intinstic regulation is when a cell, tissue or organ system can adjust and respond to change in environment on it's own. The intrinsic is inherent in organ meaning the organ can maintain homeostatis within itself.
For example, the heart can perform intrinsic regulation for it self. The heart can perform myogenic regulation by reacting and responding to increase or decrease in blood pressure to keep the blood flow in normal blood vessel constant. It is a sublevel to control cardiac function.
Genes have different variants, called alleles. Each individual possesses two alleles for each gene (one inherited from its father, and one from the individual's mother). Alleles can have different relations with each other, and some alleles have a stronger expression, dominating the determination of the trait in the individual.
In the case of codominance, both of the alleles are equally influential, so both of them are expressed in the individual.
The most famous example of codominance is in the A,B,O blood type alleles.
The A and B alleles are codominant, so when both of them are present in the individual, that individual expresses both A and B proteins, resulting in AB blood type.
Anti-parallel DNA strands refer to those DNA molecules which contain 2 DNA strands that were held together by hydrogen. In cases that the DNA strands are not anti-parallel the non-symmetrical hydrogen bond will not be possible and will cause some issues.
