Explanation:
Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.
During metamorphosis the tadpole will develop back legs first, then front legs. Around 6 weeks of life the mouth starts to widen. Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear. When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!
Hope this helps!
Answer:
b. Restriction enzymes cutting DNA
Explanation:
Restriction enzymes are the enzymes that cut the DNA molecules. Their specific feature is that they digest the specific DNA sequences only. These specific DNA sequences are called restriction sites. When some restriction enzymes digest the DNA, DNA fragments with single-stranded ends are produced. These single-stranded overhangs are called sticky ends. They are called so since the DNA fragments produced by digesting DNA with one restriction enzyme have complementary overhangs that spontaneously base pair.
The correct answer to this question is D. models can be used to describe
all of the environments listed here. Creating models is a great way to
gain a more practical understanding of how the complicated scientific
processes in these environments work, and as many people are
kinaesthetic learners it can aid them in learning.
The study of health and disease within a geographic context and from a spatial perspective is medical geography.
God bless!
