Answer:
1. Nucleotides
2. Amino acids
3. Amino acids
4. Glucose
Explanation:
All the above substance described are biomolecules. They are all polymers i.e. complex molecule bond together in a long repeating chain, made up of simpler subunits called monomers. The monomers of the different biomolecules outlined above are:
1. The nucleic acids, DNA and RNA carry genetic information and are made up of many NUCELEOTIDES. A nuceleotide is a chemical combination of a five carbon sugar (pentose), phosphate group and nitrogenous base. These nucleotides are arranged sequentially to form nucleic acids (RNA and DNA).
2. Myoglobin is a protein that binds oxygen molecules and is a polymer of AMINO ACIDS. Amino acids are the building blocks of proteins. They are arranged to form a 3D structure that determines the function of the protein.
3. Insulin is a protein hormone that regulates blood glucose levels and is a polymer of AMINO ACIDS. All proteins are made up of the amino acid but the protein's function is dependent on the 3D structure formed by the amino acid sequence.
4. Animals store energy in the form of glycogen, a carbohydrate made up of thousands of monosaccharide (GLUCOSE). Glycogen is a polysaccharide made up of many monosaccharide units. These units are glucose molecules that are multibranched to form the glycogen that stores mainly in the liver and muscles of animals.
<span>A sample that is large and randomly selected<span> is most likely to yield generalizable results. A large and randomly selected sample shows the real diversity of the population with little relevance of bias within the findings and produces generalizable results. Also, the results from the sample gives accurate representation of the larger population and are easy to use.</span></span>
Answer: true
Explanation:
Only the mRNA made from the DNA takes part in the protein synthesis
The spindle fibers produced by the centrioles are necessary for the division of the chromosome at the time of the anaphase. In case, the centrioles do not perform their task, the genetic material in the cells may not divide equally due to the lack in the separation of the chromosomes. Hence, the problem with the centrioles may lead to the unequal division of the genetic material during the cell division process.
Hence, the correct answer is centrioles.
Isotopes are atoms of the same element with the same atomic number but different mass number. unstable atoms atoms undergoes radioactive decay. Therefore radioactive decay is the process by which unstable nucleus loss energy by emitting radiations such as beta , alpha and gamma particles.
The initial mass of radium-226 is 6 grams and the new mass is 0.375 grams therefore the number of half lives undergone are 0.375 = 6× (1/2)n where n is the number of half lives. (1/2) n = 1/16
therefore n= 4. Meaning the isotope radium-226 has undergone 4 half lives
1 Half life = 1600 years
4 half lives = 1600 years × 4 = 6400 years
therefore, the rock reached its closure temperature 6400 years ago and secondly when the rock was discovered it had 5.625 g mass of radon-222.
