1. The nucleic acids DNA and RNA carry genetic information and are made up of many . 2. Myoglobin is a protein that binds oxygen
OverLord2011 [107]

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.

Many people think that summer is warmer because the earth is closer to the sun at that time of year. Your experience with season
Damm [24]
Because the earth's axis is tilted. ... It is all about the tilt of the Earth's axis. Many people believe that the temperature changes because the Earth is closer to the sun in summer and farther from the sun in winter. In fact, the Earth is farthest from the sun in July and is closest to the sun in January!

The Demaris family is deciding how to landscape their new home. A garden center offers a wide variety of grasses, as well as nat
Dominik [7]

Answer:

Resilient landscape is defined as the property of landscape to mainatin itslef with desired ecological functions, biodiversity, and robust native. The property of grasses and plants that will help the Demaris family choose a resilient landscape are:

  • Healthy root systems: It will saturate the ground water and will keep the wind from overbalancing the vegetation.
  • Group of shrubs can reduce the wind hitting home in a storm.
  • Trees with flexible trunks and limbs: flexible trunk of grasses are wind resistant and provide resilient landscape.

some of the type of grasses that provide resilient landscape are tall fescue, hybrid bermuda and perennial ryegrass et-cetra.

A researcher incubates a cell with radiolabeled amino acids. These amino acids are incorporated into the proteins as they are sy
Nonamiya [84]

Answer:

During an investigation, the addition of radiolabeled amino acids during protein synthesis occurs when the data shows high levels of radiation in protein synthesis, packaging and transport, which is equivalent to saying that radioactivity levels would first increase in the rough endoplasmic reticulum, followed by the Golgi and then the secretory vesicles (option C).

Explanation:

Protein synthesis in the cell is a process that involves the formation of polypeptide chains with the successive incorporation of amino acids.

RNA, which contains the sequence of triplets or codons that form the genetic code, is coupled to the ribosomes. Each codon or triplet consists of three nucleotides and encodes specific amino acids.

The RNA chain contains a specific nucleotide sequence and determines the assembly of amino acids to a polypeptide chain, by the action of ribosomes present in the rough endoplasmic reticulum.

In the Golgi apparatus, the proteins formed are conjugated, with the addition of carbohydrates or lipids, and arranged in secretory vesicles for transport.

In these steps, where the labeled amino acids are present, the levels of radioactivity would increase in the rough endoplasmic reticulum, the Golgi apparatus and the secretory vesicles.
