Answer:

chitin and murein

Explanation:

The chemical compounds that distinguish bacteria cell from yeast cell are  

chitin and murein

Chitin is a polysaccharide present in the exoskeleton of fungi made up of chains of modified glucose known as N-acetylglucosamine. N-acetylglucosamine is derived from glucose

While murein is a mesh like structure made up of sugar and amino acids. Murein forms a layer outside the plasma membrane of bacterial cell.

Answer:

Peptidoglycan and chitin.

Explanation:

Bacteria and yeast differ from each due to the different chemical composition of their cell wall.

Chitin: chitin is a large structural polysaccharide that is derived from chains of modified glucose. It is the primary components of cell wall in fungi such as yeast. Chitin is a minor component in the yeast cell wall, it accounts for only 1-2% of the cell wall dry mass. Chitin contributes to the mechanical strength of the cell wall.

Peptidoglycan: Peptidoglycan also known as murein is a polymer that makes up a the cell wall of a bacterium. It is composed of sugars and amino acids. A bacteria is a unicellular organism, therefore Peptidoglycan gives strength to the outer structure of the organism.

kvv77 [185]

Answer:

A) Nucleus and Ribosome

Explanation:

Diabetes can be a very chronic disease if not properly controlled, it mostly affect the aged people. If not properly treated it can in some cases lead to the death of the individual.

Diabetes occurs when the pancreas in the body system does not produce any insulin, the insulin is a type of hormone that is found in the body, this hormone helps to normalize the amount of blood sugar that is present in the human body.

The two organelles in the pancreas that is responsible for the production of insulin in the body is; nucleus and ribosome

How does the anatomy of the endocrine and integumentary systems correlate with the sense organs? What role does radiology and ut
Marta_Voda [28]
1. Every framework has their doing in arranging our body capacities. Regardless of whether it's the heart drawing blood through our body and lungs boosting oxygen and discharge carbon dioxide. Endocrine gives the correspondence through hormones; secrete their hormones directly into the bloodstream and uses blood vessels as information channels. It stimulates sebaceous glands whereas the sex hormones affect the distribution of subcutaneous fat. In addition, the endocrine system regulates metabolism, growth and development of tissues, and sexual functions. The endocrine and integumentary systems correlate with the sense organs, which react to heat, cold, vibration, texture, and pressure. When such senses are produced by the sense organs they react to the senses and send the information to the endocrine system and therefore hormones are released which causes the mood swings according to the situation. For example, it reacts to the body with pleasure or discomfort related to the senses.

2. Atomic solution and radiology bring the procedures which analyze and regard maladies by utilizing radiopharmaceuticals as the pictures of body organs or envision certain infections. This involves radiations which are used to diagnose, treat and prevent certain diseases. In the present era, these procedures are the best and hence the most effective life-saving techniques. They are safe and painless as compared to other surgical treatments involving operations. They don’t even require anesthesia. Both of these techniques are used in diagnosing a disease and monitoring the course of an illness. They are then used for the treatment of any disease as well. Diseases such as cancer or heart disease are therefore treated by radiation technology.<span>

Several organisms have a homologous protein (inherited from a common ancestor) that is highly similar at the amino acid level. Y
8_murik_8 [283]

Answer:

The correct answer is: C. third nucleotide position.

Explanation:

  • Genes located on the chromosomes encodes for proteins.
  • A Gene is made up of a  Deoxyribonucleotide (DNA) sequence which is transcribed into the messenger Ribonucleotide (mRNA) sequence by the help of RNA polymerase.
  • This mRNA sequence is further translated into the amino acid sequence, that folds to form the functional protein, by the help of the Ribosome.
  • The Ribosome reads the mRNA sequence in the form of triplets (three nucleotide together) and each such triplet nucleotide codes for an amino acid.
  • Each such triplet nucleotide is known as a Codon.
  • The Genetic Code is a table which represents the  amino acid encoded by each codon.
  • However, the Genetic Code is degenerate in nature. This means that one amino acid can be coded by more than one codon.
  • This is because, among the the three nucleotide positions in a codon only the first two determine the specificity of the amino acid while the third nucleotide, also called the wobble nucleotide, is not specific. Presence of any nucleotide in the third position of the codon will not alter the amino acid encoded by the codon.
  • In the given question, organisms producing homologous protein have similar amino acid sequence but they vary in the corresponding nucleotide sequence of the gene which codes for the homologous protein.
  • This is because at the nucleotide level the variation lies in the wobble nucleotide position that occupies the third position in the codon.

Ronch [10]

Answer;

A. Movement in his lower extremities

Explanation;

-The 1st lumbar vertebra or the L1 vertebra is the smallest and most superior of the lumbar vertebrae. As the first vertebra in the lumbar region, the L1 vertebra bears the weight of the upper body and acts as a transition between the thoracic and lumbar vertebrae.

-The lumbar vertebrae contain spinal cord tissue and nerves which control communication between the brain and the legs.
