The red-legged frog breeds in ephemeral ponds from January through March. Its relative, the bullfrog, breeds in permanent ponds from late March through May. There are two pre-mating isolation mechanism at play here,
1. Ecological isolation: The habitats are different, hence the individuals of both the species do not meet. Ephemeral ponds are temporary ponds that develop during rainy days, while the permanent ponds are full of water throughout the year.
2. Temporal isolation: The time of mating is different for both the species to avoid contact between the individuals of closely related species. Red-legged frogs mate in January to March slot and the bullfrog in the March to May slot.
hopefully this helps, these are the answers on edge
It’s C. Amino acids bind to CCA3’OH end of tRNA via ester bond.
i think it is 3a because when they are all together they are in like a clump so
OK. First, there's the heart. Then there's the blood vessels. The arteries. Then the veins. And then there's the capillaries. <span />
