Answer:
tRNA
Explanation:
The anticodon is located in the Anticodon arm of the molecule of tRNA, while the codons are located in the molecule of DNA and mRNA. The anticodon is complementary to the respective codon, and the codon in the mRNA is complementary to a nucleotide triplet from a certain gene in the DNA.
Answer:
Open circulatory systems are advantageous to some animals because they use less metabolic energy.
Explanation:
Open circulatory systems are also known as lagoon circulatory systems. In this systems the blood is not necessarily always inside the blood vessels; It leaves the heart and will directly irrigate the organs and then return by other means or mechanisms.
So that it can be understood more easily, it is necessary to think about this system acting in organisms much smaller and less complex than mammals or any other vertebrate of greater size. As this animals doesn't have a great size, they need to use less metabolic energy than more developed organisms, so this system allows them to save metabolic energy to be used in other living functions.

Answer:
The correct answer is A it transport the food generated by photosynthesis.
Explanation:
Both xylem and phloem are the examples of vascular tissue present in plants.xylem helps in the transport of water from root to different parts of the plants.
Whereas phloem helps in the transport of photo synthate from mesophyll tissue to sieve element companion cell complex.The transport of photosynthate to different non photo sythetic parts of a plant involves both symplastic and appoplastic pathway.
Symplastic pathway is a passive process depending on the pressure gradient for the transport of solutes through the plasmodesmata which connect 2 adjacent plant cells.
Appoplastic pathway is an active transport process occuring against the concentration gradient which does not involve plasmodesmata.
Answer:
Chemists research and experiment with the properties of chemical substances, improve the quality of established chemical products, measure the effects of chemical compounds in various situations, study inter-chemical reactions, and establish new technologies in the field.
