The correct option is 'a'
If osmotic pressure increases when a mussel is submerged in the water,the blood osmotic pressure also increases.
Explanation:
Mussels are bivalves that are found in fresh water as well as marine water.
They have bluish blood and small heart pumps the blood.Some mussels have red blood which contain hemoglobin that carry oxygen rather than hemocyanin.
The mussels show increase in blood chloride level and amino acid when the osmotic pressure of the water increases.
Submerging the mussel in the aquatic environment increases osmotic pressure of the mussel.
Answer:
Restriction endonuclease
Explanation:
It cut the DNA at specific sequence and it is very useful in biotechnology
Covalent bond? Carbon is usually the structure for a polymer Bc it can make up so many things including covalent bonds used to make polymers
The correct option from given options is "b", that is <span> it changed ideas about which animals were closely related.
</span>Cladistics<span> was </span>invented for the purpose of improving on taxonomy and it is a way to deal with biological classification. DNA technology lead to more use of cladistics because it changed ideas about which animals were closely related and also it showed new evolutionary relationships between animals.
I believe it is either B or A, personally i'm leaning towards B, but at the same time, i don't think that we would be obtaining materials via pollination, so it then causes A to make more sense.
