Explanation:
The answer is <span>C) crossing over.
</span>The crossover of chromosomes is the exchange of genetic material between homologous chromosomes. If it is known that homologous chromosomes are present only in the meiosis I, it is expected that crossover is occuring meiosis I.<span> Homologous chromosomes pair up in the prophase. Therefore, meiosis prophase I is the phase in which chromosomal crossover occurs. Chromosomal crossover is process that </span>helps make meiotic cells genetically <span>different.</span>
Answer:
Convergent
Explanation:
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
Frame shift, possibly new amino acids instead of the original
The impact in this case is the ventricles will beat more slowly.
Sinoatrial node acts as a pace maker for the heart skipping the plateau phase and the electric impulses are created here. This node lets the blood into ventricles.
Atrioventricular node acts as controller of heart rate and serves as an electrical relay station. This node connects the right atrium and right ventricle.
