If an animal fossil was found in a rock, what would be the best way to determine its absolute age?
LiRa [457]

Answer:

D

Explanation:

Absolute age is defined as the numeric age of fossils.

To identify the absolute age of a fossil,  the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.

Hence, the correct answer is "D".

The primary purpose of the basic economic order quantity model is
AleksAgata [21]

Answer:

D. to minimize the sum of setup cost and holding cost e. to calculate the optimum safety stock

Explanation:

Economic order quantity ( EOQ ) is formulated as :

EOQ= \sqrt[]{\frac{2C_O D}{C_h} }

Co = Ordering cost

D = annual demand

Ch = Annual unit holding cost

Economic quantity is the order quantity which minimizes sum of annual cost of ordering and annual inventory holding cost  so to minimize the overall cost of the inventory.

ANSWER : d) to minimize the sum of setup cost and holding cost that is to calculate the optimum safety stock.

What do we mean when we say that the genetic code is degenerate?A single codon can encode more than one amino acid.An amino acid
Arada [10]

Answer:

An amino acid can be encoded by more than one codon.

Explanation:

Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.

Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
