negative feedback is used to regulate feedback
Answer:
Sharks, in their basal form have been on Earth for hundreds of millions of years. They were the first to develop a stream-like, torpedo shaped body and created a niche for themselves. Their aerodynamic body shape has evolved to allow for efficient and dynamic movement in water. Having a cartilage instead of bones allowed them to grow large and still be relatively light and buoyant . After they've evolved flexible, protruding jaws, there wasn't much to change. They were able to adapt and exploit all the water habitats as the world was changing.
Explanation:
point, shift deletion, UV rays, radiations, genetics mutations, gene editing
That is just some method that gene can change within the DNA
The answer is a pedigree chart.
<span>Pedigree charts are used to explain the occurrence of
particular genes from one generation to the next. It gives enough information
about family disease history. They are used in families to find out the
probability of inheriting some disease. So, if Maria and Juanita are cousins
and the genotypes of other members of their family are known, the pedigree chart
could predict their genotypes. Still, it is not as precisely as DNA test.</span>
They are both important because mechanical has to do with physical - cause mechanical means physical, so chewing your mouth is physical (you break your food into smaller pieces physically). And then chemical digestion is when food and saliva mix together. They happen when breaking down food into nutrients - enzymes. Enzymes are important for that process, because they make a nutrient.
Hope this helps!!
