Which two statements are true regarding an energy pyramid

1 answer:

7 0

This is an ecosystem energy pyramid that illustrates how much energy is found at each trophic level of a food chain. Select all the statements about this pyramid that are TRUE.

Approximately 90% of energy from one trophic level is transferred to the next trophic level.

Looking at the total amount of energy in an ecosystem, most energy can be found in the primary consumers.

This energy pyramid explains why there are few tertiary consumers in most ecosystems.

Looking at the total amount of energy in an ecosystem, most energy can be found in the producers.

Bone marrow transplant taken from a donor and infused through the central vein is coded to what icd-10-pcs code

slava [35]

The ICD-10-PCS code is 30240G4.

Firstly, select "Administration" (section 3) because the procedure is the administration of bone marrow to the patient. Secondly, select "Circulatory" (section 30) because it is being administered in a vein (circulatory system). Third, select "Transfusion" (section 302) because it is being done a transfusion of bone marrow. Then select "Central Vein" (section 3024) because that's the place of administration in the circulatory system. Lastly, go to "Bone Marrow" (section 30240G) as that is what's being transfused and then choose "Transfusion of Allogeneic Unspecified Bone Marrow into Central Vein, Open Approach" (30240G4) because it is not specified what type of transfusion it is.

Gel analysis of fragments in step 6 shows that even though the undigested DNA and DNA digested with HindIII are both 1000 bp, th

Soloha48 [4]

Answer:

Size of the band varied

Explanation:

In the given question, the options are not provided but based on the information provided in the question, it can be predicted.

When the DNA was digested by the HindIII, then the length of the digest came about 1000 bp and the undigested DNA was also found 1000 bp.

When both the bands were analysed by Gel electrophoresis then the bands do not run to the same distance therefore this shows that the size of both the bands was not equal and their size varied.

Thus, the size of the band varied is correct.

The major difference between starch, glycogen, and cellulose and their adjacent glucose subunits is the ________.

sveta [45]

Answer:

Starch is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

Cellulose is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

Glycogen is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.

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.
