a. 1500 j
b. 14,700 j
c. 1.7 j
b. 14,700 J
Because,
Potential energy
= m.g.h
= 30 kg × 9.8m.s^-1 × 50m
= 14700 kg.m^2.s^-2
= 14700 J

In DNA and RNA, what “codes for amino acids”?
combinations of nucleotides
combinations of sugars
combinations of proteins
combinations of strands
Answer:
The correct answer is - combinations of nucleotides
Explanation:
The codes for amino acids are encoded in the DNA and RNA in the form of the trinucleotide codons that contain three base sequences which copied in the complementary bases sequence mRNA and then decoded by the ribosome with help of tRNA to produce the original sequence in amino acid sequence or peptide chain.
This nucleotide is also code in the set of 3 base sequences similarly one amino acid is made up of the triplet code.

Answer: The correct option is C.
Cloning vectors.
Explanation:
Viruses are use as cloning vectors because they can give the new gene or birth the new gene by infecting the cell. They are so modified and orogrammed in such a way that they cannot cause disease when it is used in humans. Cloning vector is a DNA fragment gotten from viruses or bacteria plasmid which is maintained and used for cloning purposes.

why is the interaction of the respiratory and circulatory systems necessary for the frog survival please refer to oxygen and carbon dioxide?
In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.
How is the respiratory and circulatory system of amphibians?Amphibians have three structures for breathing:
The lungsThe mucous membranes of the pharynx and mouthand The skin.The lungs are made up of two bags with no internal division. When still in the larval stage, they breathe through gills.
How does the circulatory system of amphibians work?Amphibians have a dual circulation, meaning the blood passes through the heart twice to complete the cycle. The blood reaches the heart, travels towards the lungs, returns to the heart and only then is carried to the body.
Whit this information, we can conclude that In the circulatory system there is the distribution of oxygen to the body and in the respiratory system the gas exchange.

The chemical equation of cellular respiration contains information about?
a. the relative amount of products and reactants.
b. the formation of glucose.
c. the intermediate reactions needed to break down glucose.
d. the environment in which cellular respiration occurs.
The chemical equation of cellular respiration comprises information regarding the relative amounts of products and reactants.
• The process, which takes place within the mitochondria of all the organisms is termed cellular respiration. In this process, the simple sugars are dissociated into water and carbon dioxide and release energy in the form of ATP.
• A chemical reaction is a procedure in which one or more components, that is, the reactants get transformed into one or more different components called the products.
• The substances, which start the reaction are called reactants, while the ones that get produced in the reaction are called products.
• The association between the reactants and products in a chemical reaction can be signified with the help of a chemical equation.
Thus, the chemical reaction of cellular respiration comprises information regarding the relative amount of products and reactants.

4: energy
Answer:
3. All of these
Explanation:
When the reaction of cellular respiration occurs, carbon dioxide and water is created while energy gets released.
Answer:
3: all of these
Explanation:
They actually form ATP, which is essentially energy. Byproducts are water and carbon dioxide. I would say all of these answers are true! Remember though, ATP (energy) is the main product while water and carbon dioxide are byproducts.
