Answer:
The creation of the limbs is carried out by AER and ZVP. AER stands for apical ectodermal ridge and ZVP stands for polarising activity line.
Explanation:
- AER is responsible for the developmental progression in the distal to the anterior region and the ZVP is liable for the progressive advancement in the posterior to a backward region.
- AER and ZVP are interconnected on one another in the secretion of a sonic hedgehog, which eventually assists throughout the hox speech to promote the growth of the arm.
- The hypothesis that the new short-arm gene inhibits the effect of FGF (fibroblast growth factors) on AER can be tested and use a template of cultured cells.
- The AER may be disrupted in the model and the impact of the gene encoding on FGFs may be examined. If in the existence of a viral vector, the role of the FGFs is to trigger correct growth, then the hypothesis is incorrect, or else the hypothesis is right. The FGF8 is by far the most powerful of all as the result.
Answer:
Populations evolve, not individuals. ... Individual organisms do not evolve, they retain the same genes throughout their life. When a population is evolving, the ratio of different genetic types is changing -- each individual organism within a population does not change.
Answer:I think it is part B
Explanation:
Yes it can kill brain cells. if you hold your breath for a short amount of time example 10 seconds it won't do any harm. but if you hold your breath for an extended time like a minute the cells will not get enough oxygen and eventually die. I hope I helped you
The circulatory system provides your brain with a constant supply of oxygen rich blood while your brain regulates your heart rate and blood pressure meanwhile your bones are busy making new blood cells. working together these systems maintain internal stability and balance otherwise known as homeostasi
