The main function of the respiratory system is to allow the exchange of gases between the atmosphere and the lungs. Hence,the only structure that carries out this function is the alveoli as other structures such as the nose,trachea and pharynx transport gases to the alveoli just so that it can can out its function.

Suppose that the mice with unlimited access to water produced more urine than the mice given no access to water. how would that
kupik [55]

<span>The ratio of both groups would stay the same. Reason being the ratio in urine osmolality is divided by blood osmolality. The mice with no access to water the ratio of urine osmolality to blood osmolality are 14:7 while for mice with unlimited access to water the ratio of urine osmolality to blood osmolality is 1:4. In conclusion, the mice with no access to water produce highly concentrated urine.</span>

Cómo clasificarías la Adenina​
stiks02 [169]

Classification of Adenine is given below.

Explanation:

  • Adenine is one of the four bases that make up DNA. It corresponds to the letter A of the sequence that combines A, C, G and T in the DNA. Adenine has the property that, when it is in the double helix, it is always forming a pair with the thymine of the opposite strand.
  • Adenine is one of the five nitrogenous bases that are part of nucleic acids (DNA and RNA) and in the genetic code is represented by the letter A. The other four bases are guanine, cytosine, thymine and uracil. Adenine is always paired with thymine in DNA.
  • A chemical compound that cells use to make the fundamental elements of DNA and RNA. It is also part of many substances in the body that provide energy to cells. Adenine is a type of purine. DNA structure.
  • The adenine formula, which is derived from purine, is C5H5N5. It is a component of the nucleic acid chains that is in the nucleotides, as is the rest of the nitrogenous bases of RNA and RNA (uracil, thymine, cytokine and guanine).
  • Cytosine (C) is one of the four bases of DNA, the other three being adenine (A), guanine (G) and thymine (T). Within the DNA molecule, the cytosine bases are located in a chain forming chemical bonds with the guanine bases of the opposite chain
  • Adenine and thymine are complementary (A = T), linked by two hydrogen bridges, while guanine and cytosine (G≡C) are linked by three hydrogen bridges. Since RNA does not contain thymine, complementarity is established between adenine and uracil (A = U) by two hydrogen bridges.

Correctly label the anatomical features of the muscle filament.
irina [24]

The labeled anatomical features of the muscle filament are attached as an image.

Muscle filament or Myofilaments are the two protein filaments of myofibrils in muscle cells. The two proteins are myosin and actin and are the contractile proteins involved in muscle contraction.

  • It has two filaments, a thick one made up mostly of myosin, and a thin one composed mostly of actin
  • Actin is a filament made up of protein that contributes to the contractile property of muscle. It is found in two forms, G-actin (monomeric globular actin) and F-actin (polymeric fibrous actin)
  • Tropomyosins are contractile proteins that regulate contraction in both muscle and non-muscle cells with help of myosin and actin filaments. It is present in animal cells.
  • A troponin complex is a group of three proteins, troponin T, troponin I, and troponin C, subunits located on the thin filament of the contractile apparatus.

Thus, the correct labeled anatomical features of the muscle filament is attached as an image.

If wolves had not been brought to the island what factors might influence the deer population size?
olasank [31]

The deer population would increase because nothing is killing them, but competition would eventually occur because they would have to start fighting against each other for resources to live.
