The sides of the DNA molecule, the rails of the ladder, are composed ofA. phosphates only.
B. nitrogenous bases only.
C. phosphates and sugars.
D. nitrogenous bases and sugars.

Answers

Answer 1
Answer: The answer is letter C. The sides of the DNA molecule, the rails of theladder, are composed of phosphates and sugars.

DNA strands constitute chemicals called nucleotides. DNA molecules on the otherhand  are made up of 2 polynucleotide chains. This polynucleotide isarranged on the backbone, the double helix.  These nucleotides(polynucleotide and nucleotides) are composed of three parts: a phosphate, asugar (deoxyribose), and a type of compound base. Deoxyriboseand phosphate creates the backbone of the side of the ladder, nucleic acidwhile the base join both polynucleotide chains like the rungs of the ladder.  
Answer 2
Answer: c. phosphates and sugars.

The alleles for eye color in fruit flies involves one allele that might contain the sequence CCAT. Assume that this allele produces red eyes in a fruit fly, because the allele produces a protein that makes red pigment. Assume that another allele of this gene has a slightly different sequence in the middle: CAAT, instead of CCAT.Which of the statements below is true about the alleles for eye color in fruit flies? Which of the statements below is true about the alleles for eye color in fruit flies? A) The alleles for eye color produce the same phenotype. B) The small change in the DNA sequence causes the allele to produce a different protein, resulting in the production of white eyes instead of red eyes in the fruit fly. C) Changes in the sequence of DNA bases in a gene do not contribute to genetic variation in the fruit fly population

Four major classes of organic compounds found in living organisms are proteins, carbohydrates, _____.

Answers

Answer:

Nucleic acids and lipids.

Explanation:

Biomolecules may be defined as the organic molecules present in the living organism that plays the important role in their growth and metabolism. Four important biomolecules are carbohydrate, protein, nucleic acids and lipids.

Carbohydrate is the polymer of sugars. Amino acids are linked together to forms the proteins. Nucleic acids are the polymers of the nucleotides. Lipids constitute of the hydrocarbon chain and hydrophilic carboxylic acid group.

Thus, the answer is nucleic acids and lipids.

what do u mean by this chromosones contain information of inheritance of character from parent to next genration in the form of dna

Answers

Answer:

Explanation:

DNA are the building blocks of chromosome. Think about a blueprint. Blueprint contain instructions of how to build something, the actual instructions are the drawing and those drawings are housed on the blue paper.

So if you connect that analogy to this, DNA is actually the code that tells your cell how to do, what to do and such, they are actual genetic codes with bases such as Adenine, Guanine, Cytosine, and Thymine arranged in a double helix pattern. The chromosomes are the structures that are a result of arrangement of billions and billions DNA bases, thus they are the structures that house DNA and gene (part of DNA that codes for stuff)

What are two of the processes that move tectonic plates over the surface of earth

Answers

tectonic plates float on amass of melted lava. its very hot and produces gases. these gases tend to move the plates with the compression becomes very high and the gases do not find an exit.the other reason is the plates themselves tend to move. because of the temprature gradient. the plates are hotter on the lower side which forces the plates to move up. and they are colder on the outside,which forces the plates to move downward..this is the other reason why the plates move

Enzyme, antibody, hormone, and muscle are roles played by _____.carbohydrates
proteins
lipids
nucleic acids

Answers

Answer:

Proteins.

Explanation:

Protein is one of the major biomolecule of living organisms and acts as a main building block of the body. Proteins are the polymers of amino acids.

Most of the enzymes present in living organism are made upof proteins. Antibodies made up of heavy and light chains are the constituent of proteins. Hormones like insulin, glucagon and epinephrine are proteinaceous in nature. Muscle contains protein like actin, myosin and nebulin. Hence, protein can act as antibody, enzyme, muscle and hormone.

Thus, the correct answer is option 2.
