<span>Molecular clock is a scale which uses a technique whereby evolutionary time for different life forms is deduced from the mutation rate of biomolecules. Biomolecular data used for calculations in order to come up with the prehistoric time scale normally uses nucleotide sequences for DNA or amino acid sequences for proteins.
Hence, in order to develop a molecular clock, one would need: a sequence of molecules, the rate at which changes occur in a type of molecule and how much total change has occurred in a type of molecule from different species.</span>
Answer:
1.yes
2.no
3.yes
Explanation:
1.Yes. The sugar in milk comes from naturally occurring lactose, not added sugar.There are about 12 grams of natural sugar (lactose) in each 8-ounce glass, which is about the same amount of natural sugar you would find in one small banana. Flavored milk, like chocolate, does contain added sugar for flavor.
2.In lactose-free dairy, the lactose is predigested into glucose and galactose. Consequently, the lactose content may be very low (<0.1 g/L), but the glucose and galactose content of lactose-free milk will be approx. 25 g/L.There is no added sugar in plain lactose-free or regular milk.
3.milk is composed of two molecules of simple sugars—glucose and galactose—that are chemically bonded together. The enzyme lactase breaks down lactose into glucose and galactose, which are easily digested by humans.
Yess as long as you have water
Answer is A.
Cell have to spilt themselfs apart to make more cells for the system. Tree are like cells because they sometimes have seeds in them that help generations of trees grow!
