Answer:

To create positive and negative ends to attract and hence combine with each other.

Explanation:

Two molecules combine usually by some sort of attraction between them.

When one molecule loses OH- ion, it becomes positively charges while the other molecule loses H+ ion and becomes negatively charged.

Now two molecules , one electro positive and other electro negative attracts each other and combine by forming hydrogen bonds.

Like wise the H+ and OH- released, also combines to form water.

The loss of the hydrogen on one molecule produces a negative charge, which is attracted to the positive charge formed by the loss of the hydroxy group from the other molecule.

A synovial joint is surrounded by a two-layer ____________ which encloses a fluid-filled space called the ____________ . the out

zloy xaker [14]

<h3><u>Answer; </u></h3>

<em><u>-Joint capsule </u></em>

<em><u>-Synovial cavity </u></em>

A synovial joint is surrounded by a two layer<em><u> joint capsule</u></em> which encloses a fluid filled space called the <em><u>synovial cavity. </u></em>

<h3><u>Explanation; </u></h3>

<em><u>Synovial joint is a type of a joint that joins bone with fibrous joint capsule which is continuous with periosteum of the bones that have been joined. </u></em>

<em><u>Joint capsule is an envelope that encloses the synovial joint and is also known as the articular capsule</u></em>.

Joint capsule comprises of an outer fibrous layer membrane and the inner synovial layer membrane.

<h3><u>Answer; </u></h3>

Dense connective tissue

The outer layer of this structure consists of <em><u>dense connective tissue</u></em> which is continuous with the periosteum of each bone

<h3><u>Explanation; </u></h3>

<em><u>The outer layer of the joint capsule is a fibrous membrane that is attached to the circumference of the articular end of each bone on the joint, therefore it surrounds the articulation. </u></em>

This layer is made up of dense connective tissue which is irregular that is continuous with the periosteum of each bone in the joint. The tissue is a long spongy tissue

<h3><u>Answer; </u></h3>

Ligaments

The outer layer may be reinforced by<em><u> ligaments </u></em>which are bundles of collagenous fibers. Some of these bundles are part of the capsule while other are located outside of the capsule.

<h3><u>Explanation; </u></h3>

<em><u>Ligaments are fibrous connective tissues that help in the articulation of bones to other bones. Ligaments are bundles of collagenous fibers which appear as a crisscross bands which attach bone to bone and help in the stabilization of joints. </u></em>

<u><em>Ligaments surrounds a joint to give it support and also limits the movement of these joints. </em></u>Therefore when ligaments are damaged, the joints involved becomes unstable.

<h3><u>Answer; </u></h3>

Accessory structure

By definition, the structures, such as some ligaments, that are located outside the capsule are called<em><u> accessory structures. </u></em>

<h3><u>Explanation; </u></h3>

<em><u>The synovial joint such as the knee joint contains a synovial cavity and dense, irregular connective tissue which makes the joint capsule normally associated with accessory ligaments</u></em>. These structures are called the accessory structures of the synovial joints.

<em><u>The accessory structures are the pieces that help to strengthen and connect the joint. </u></em>They include the fibrocartilage, fat pads, tendons, Accessory, Extracapsular, intracapsular ligaments and the bursae.

<h3><u>Answer; </u></h3>

Synovial membrane

The inner layer of the joint capsule is <em><u>the synovial membrane,</u></em> consisting of loose connective tissue.

<h3><u>Explanation; </u></h3>

<em><u>Synovial membrane is a connective tissue which lines the inner surface of the joint capsules in a synovial joint and the tendon sheath. </u></em>It may be described as a layer that lines the cavities of synovial joints bursae and the tendon sheaths.
<u><em>The membrane functions to secrete the synovial fluid which lubricates the articulating joints.</em></u>

<h3><u>Answer; </u></h3>

Synovial fluid

The inner lining of the joint capsule secretes a fluid called <em><u>synovial fluid. </u></em>This fluid is viscous, and moistens and lubricates the surfaces within the joint capsule

<h3><u>Explanation; </u></h3>

<em><u>Synovial fluid is a special type of viscous fluid that is secreted by the synovial membrane in a synovial joint such as knee joint whose function is primarily lubrication of the joint. </u></em>
<em><u>The fluid contains special contents such as hyaluronan, lubricin and the interstitial fluid </u></em>which help in the reduction of friction between the articular cartilage of synovial joints when the joints are moving.

For each statement, choose the term that completes the sentence. Play many roles in the body and determine many traits. In human

Korvikt [17]

Answer:

The first blank can be correctly filled up with proteins.

Proteins are complex molecules which play many crucial roles in the body such as structural role (actin, myosin, keratin), movement, metabolism (enzymes), signal transduction, transport, and defense. In addition, they also determine many traits of the body as they are the last result of the gene expression.

The second and third blanks can be correctly filled up by DNA (deoxyribose sugar).

DNA is the genetic material in most of the organisms including humans. It contains all the information or blueprint for the synthesis of proteins which in turn help in determining the traits of a person.

The last blank can be filled up by the gene.

A gene refers to the unit of heredity which is present on the chromosome. It refers to the protein coding region of the DNA.

The __________ process occurring in the liver rids the bloodstream of 90% of the alcohol present and is a constant process.

snow_lady [41]

The following options are attached to the above question:

A. Metabolism

B. Absorption

C. Oxidation

D. Excretion

ANSWER

The correct option is C.

Biological oxidation of alcohol is the process by which the liver handles the presence of alcohol in the body system. The liver is responsible for metabolizing the alcohol that are present in the body. The metabolism of alcohol occurs in two steps; the first step is the oxidation of alcohol to ethanal or acetaldehyde. This product is very toxic to the human body and is majorly responsible for the symptoms of hangover that drinkers usually experience. The liver oxidises ethanal to acetic acid as quickly as possible in order to prevent damage to the body system.
