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".

A, B, C, D and E are pathogens of different diseases for human beings. The route of entry of pathogens in human body is differen
Goryan [66]

Answer:

Microorganisms which causes diseases is known as pathogen.

Explanation:

<u>PATHOGEN -:</u> Pathogens are agents that live in a host and are responsible for causing infections or diseases in that host, such as a human being. Microorganisms such as bacteria , viruses , fungi or protozoa, or other organisms such as parasites, worms and even contagious proteins such as prions, may be pathogens.

<u>Viruses:</u> Viruses are micro-organisms that are composed of nucleic acid and covered by a protein sheet. A lipid (fatty) outer layer is also present in some viruses. Enveloped viruses are called these. Non-enveloped viruses are considered those that do not have this lipid outer layer. Only inside their host's living cells are viruses able to replicate.<u> EXAMPLE -:</u>  Influenza (influenza A and B viruses) and the common cold (rhinovirus) are examples of infections caused by viruses.

<u>Bacteria: </u>These are microorganisms which have a nucleus containing DNA surrounded by a cell wall or membrane. Among bacteria, the composition of the cell wall differs. If they are able to access food and nutrients, they have a more complex structure than viruses and can multiply beyond the host.<u> EXAMPLE -: </u> Foodborne diseases can be caused by bacteria such as Salmonella enterica and Escherichia coli, while Staphylococcus aureus can cause skin infections.

<u>Fungi:</u> Fungi are single-celled or multicelled species that can live outside a host. They consume food and nutrients created after digestive enzymes have been secreted into their atmosphere. <u>example-: </u> The foot of the athlete (Trichophyton mentagrophytes) and yeast infections (Candida albicans) are examples of infections caused by fungi.

<u>Prions:</u> These are infectious agents made up entirely of proteins and capable of transferring to other prion proteins their infectious properties.<u> EXAMPLE -: </u>Extreme infectious diseases such as bovine spongiform encephalopathy (mad cow disease) and variant Creutzfeldt-Jakob disease (vCJD) can be caused by prions.

<u>Protozoa: </u>Protozoa are single-celled organisms that display habits that are similar to animals, such as the ability to travel through water, and are capable of harvesting other microorganisms. They are able to live outside the human host, but when they enter the human host and spread, causing infections and diseases, they may also be parasitic in nature. <u> EXAMPLE -: </u>Malaria and giardia include common infections

  • <u>Yes , pathogen enter into the body directly -:</u> Direct contact infections spread when, through direct physical contact with blood or body fluids, disease-causing microorganisms move from the infected person to the healthy person. Touching, kissing, sexual contact, contact with oral secretions, or contact with bodily lesions are examples of direct contact.
  • <u>INCUBATION PERIOD OF A PATHOGEN -</u>:The period of incubation is the interval between exposure to a pathogenic organism, a drug, or radiation, and when the first signs and symptoms are evident.

The expression 40x2 – 65x + 50 represents the sum of the interior angles of a regular pentagon in degrees. If the interior angle
Nadya [2.5K]

Answer:

2(8x^2-13x+10)

Explanation:

There are 5 angle s in a pentagon and we are assuming are pentagon is a regular one so the angles are all congruent.

Let's let A represent the measurement of one of the those angles in our pentagon.

The sum of our angles in our pentagon would then be A+A+A+A+A or 5A.

But we are also given that this equals 40x^2-65x+50.

So that means 5A=40x^2-65x+50.

If we divide both sides by 5 we can find what one of our angles is in terms of x.  So let's do that A=8x^2-13x+10.

So we want to know the sum of two our angles, we want to know what is A+A or 2A.  2A=2(8x^2-13x+10).  To obtain that I just multiplied both sides of A=8x^2-13x+10 by 2.

Watson and Crick first built a triple-helix model of DNA. In this model, the nitrogenous bases were on the outside of the DNA mo
Sedaia [141]

Because it makes accessing them easier for the cell, it is assumed that the bases will be on the outside of the DNA molecule.

<h3>What is DNA molecule?</h3>
  • Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.
  • Each nucleotide is made up of a phosphate group, a deoxyribose sugar, and one of the four nitrogen-containing nucleobases (cytosine [C], guanine [G], adenine [A], or thymine [T]).
  • An alternating sugar-phosphate backbone is created when the nucleotides are linked together in a chain by covalent connections (also referred to as the phospho-diester linkage) between the sugar of one nucleotide and the phosphate of the next.
  • To create double-stranded DNA, the nitrogenous bases of the two distinct polynucleotide strands are joined by hydrogen bonds in accordance with the base pairing principles (A with T and C with G). Pyrimidines and purines make up the two families of complimentary nitrogenous bases.
