Why is it important to have both negative and positive feedback loops in the body

Biology
1 answer:
ELEN [110]2 years ago
7 0

Answer: positive feedback loops enhance or amplify changes. this tends to move a system away from its equilibrium state and make it more unstable. Negative feedbacks tend to dampen or buffer changes. this tends to hold a system to some equilibrium state making it more stable.

____________ is translated by the ribosomes and contains the code that specifies the sequence of amino acids in a polypeptide ch
HACTEHA [7]

mRNA (Messenger RNA) is translated by ribosomes and contains the code that specifies the sequence of amino acids in polypeptide chain.

A single-stranded ribonucleic acid molecule is known as messenger RNA(mRNA) plays a major role in <u>translation</u>.

Translation is the method by which an mRNA codes for a certain protein. mRNA provides the template for<u> protein synthesis</u>.

The ribosome translates the mRNA that is produced from the DNA into a chain of certain amino acids and<u> protein synthesis</u> is facilitated by this <u>amino acid</u> sequence.

<u>The genetic code</u>, which connects the DNA sequence to the amino acid sequence of proteins, is used to "read" the mRNA. Each group of three nucleotides in mRNA forms a codon, and each codon corresponds to a particular amino acid (triplet code).

Thus mRNA contains the code that specifies the<u> sequence of amino acids</u> in a polypeptide chain.

A simple diagram of a DNA molecule is shown below. Which of the following is represented by X?
Reil [10]

Answer:

From the diagram X = <u>base pairs</u>

Explanation:

Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.

Nucleotides comprise:

  • a 5-Carbon deoxyribose sugar,
  • one nitrogenous base (adenine, guanine thymine, and cytosine)
  • and a phosphate group.

Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides  Thymine and Cytosine (pyrimidine bases) along with Guanine,  and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.

Manifestations of osteoarthritis include ( Select all that apply.) nodules on joints of the hands. crepitus with joint movement.
fiasKO [112]

Answer:

All options are correct, that is, they would all be correct for osteoarthritis.

This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.

Explanation:

Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.

The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).

This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".

What is the primary way that metamorphic rocks form?
allochka39001 [22]
<span>Metamorphic rocks form by existing rocks join together under high heat and pressure. Examples of metamorphic rocks are marble, schist, slate, and quartzite. Metamorphic rocks formed when the minerals are chemically changed due to heat and pressure. They are often seen near magma but they do not melt like igneous rock.</span>
