Frogs do have lungs but they are small and rarely used, frogs mostly take in moisture through the skin in process called cutaneous gas exchange.
Answer:
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection. The theory of evolution is based on the idea that all species? are related and gradually change over time.
Explanation:
The degree to which chromatin is compacted greatly affects its accessibility for transcription, and thus, gene expression.
<h3>What is Transcription?</h3>
This is the process which involves copying a segment of DNA into RNA in organisms.
When chromatin is condensed, DNA becomes less accessible for transcription factors and vice versa which was why it was chosen as the most appropriate choice.

Both parents must be carriers, which means they have the heterozygous gene (one uppercase letter & one lower case letter). They will still carry that mutated gene (because they have a lower case letter), and their offspring will have a 25% chance of getting a recessive disorder. The percentage is low but still possible.
Answer:182.25 joules
Explanation:
Mass=0.18kg
Velocity=45m/s
Kinetic energy=(mass x(velocity)^2)➗2
Kinetic energy=(0.18 x 45^2) ➗ 2
Kinetic energy=(0.18x45x45) ➗ 2
Kinetic energy=364.5 ➗ 2
Kinetic energy=182.25
Kinetic energy=182.25 joules
