Small fish absorb minute amounts of pesticides.
The birds of prey consume many fish to satisfy their dietary needs. The pesticides accumulate and concentrate in the bird, continued exposure overwhelm the predator.
Answer:
Withdrawal methods, breast feeding methods
The correct answer is: The speed of sound is faster in the water than in the air.
The speed of sound is different between those two mediums because they have different densities. Since, water is denser than air, more energy is required to generate a wave but once it stars, it travels faster than it would do in air. Sound waves’ travel can be presented by particles that transmit the energy one to another as they bump. The sound speed is lower in the air (than in water) because particles are far apart, so they travel further before they collide.
Answer:
(2⁵)²: 1024 combinations
Explanation:
In this case, the chromosome haploid number (n) of the target species is equal to 10, and therefore its diploid number (2n) is equal to 5 (i.e., somatic cells in the target species contain 5 pairs of chromosomes). That means that one individual can produce 2⁵ or 32 different gametic combinations. Moreover, the number of possible combinations that emerge from paring different gametes (sexual reproduction) can be calculated as (32)² = 1024 combinations.
