Explanation:
The pulmonary artery (trunk) exits the right ventricle and carries deoxygenated blood to the lungs for oxygenation. The pulmonary veins return oxygenated blood from the lungs to the left atrium. The aorta distributes oxygenated blood to the body, and the vena cava returns deoxygenated blood to the heart.
Explanation:
Genetic drift is a random change in allele frequency, more pronounced in small populations, and can reduce genetic diversity. Natural selection leads to adaptation.
Explanation:
The '9+2' arrangement refers to nine doublets of microtubules surrounding a central pair, which is the classic axoneme structure of motile cilia and flagella. Centrioles and basal bodies possess a '9+0' arrangement (nine triplets, no central pair). Mitotic spindle fibers are single microtubules, and intermediate filaments lack a tubular microtubule structure entirely.
