Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poorblood from the body into the right atrium of the heart.i As the ventricle contracts, blood leaves the heartthrough the pulmonic valve, into the pulmonary artery and to the lungs where it is oxygenated
How does blood flow through the heart step by step?
Blood from the body flows:
1. to the superior and inferior vena cava,
2. then to the right atrium.
3. through the tricuspid valve.
4. to the right ventricle.
5. through the pulmonic valve.
6. to the pulmonary artery.
7. to the lungs
Answer:
New species develop when:
D. Diverging species no longer recognize one another as potential mates.
Explanation:
- The development of two or more new species from ancestral population is known as speciation.
- Speciation can occur when the population divides into groups and each group occupies a different habitat (geographic isolation) or when the members of the same population do not find one another as potential mate and do not interbreed (reproductive isolation mechanism).
- The three types are: Allopatric speciation.
Sympatric speciation.
Parapatric speciation.
- Allopatric speciation occurs when genetic divergence is allowed through geographic isolation.
- Sympatric speciation does not involve geographic isolation but involves reproductive isolation mechanisms.
- In Parapatric speciation, a population enters a new niche or habitat within the range of parent species and then evolution of reproductive isolation mechanism occurs.
