Answer:

The most frequently damaged tissues are the skin and mucosa, which causes the body to activate a repair process consisting of the following steps:

1- Inflammation: This process involves the cells of the immune system, white blood cells, antibodies, lymphatics. All these cells work together, once the vessels expand, they act producing an inflammation process where coinside these cells eliminating necrotic tissue, bleeding and coagulation is formed.

2- Organization: In this step, the clot begins to form in granulation tissue that is a tissue composed of several elements and that goes from the central part of the lesion to the periphery. In this stage new capillaries grow, fibrolastic tissues are formed that produce growth factors and collagen fibers.

3- Regeneration: A superficial epithelial tissue begins to grow under the granulation tissue. As the underlying fibrous tissue matures and becomes fibrous until it finally resembles the adjacent skin. Finally forming a fully regenerated epithelium.

In what way are aldosterone and atrial natriuretic hormones antagonists?

Luba_88 [7]

Explanation:

Aldosterone is steroidal hormone which is produced by outer-section of adrenal cortex in adrenal gland. It acts on distal tubules and the collecting ducts of kidney to cause conservation of the sodium by facilitating the secretion of the potassium and increased water retention.

Atrial natriuretic hormones are natriuretic peptide hormone which are secreted from cardiac atria. Main function of the hormone is causing reduction in the volume of the expanded extracellular fluid by increasing the renal sodium excretion.

Thus, Atrial natriuretic hormones causes sodium and the Water loss while Aldosterone helps in the conservation of the sodium and water retention.

Microfilaments and microtubules are part of the __________ of a cell.

xxMikexx [17]

Answer: Option A. "Cytoskeleton"

Explanation:

Cytoskeleton can be defined as the network of protein filaments in the cytoplasm eukaryotic cells interlinking from cell nucleus to cell membrane.

There are three basic types of protein fibers present in cytoskeleton that includes micro filaments (Actin filaments ), microtubules and intermediate filaments.

Microfilaments are consist many linked monomers of a protein known as actin, that combines in a double helix with a diameter of about 7 nano-meter and functions as serving tracks for myosin (motor protein).

Microtubules are arranged in a form of hollow straw like structure made up of consist of tubulin proteins having diameter of about 25 nano-meter and further consist of two subunits, α-tubulin and β-tubulin.

Intermediate filaments are the cytoskeletal element which are made up of multiple strands of fibrous proteins wounded together having an average diameter of 8 to 10 nano-meter.

Why is an increased target-receptor distance required in the paralleling technique?

klio [65]

To prevent image magnification increased target-receptor distance required in the paralleling technique.

Magnification- A microscope's capacity to generate a picture of an item at a scale that is bigger (or even smaller) than its real size is known as magnification.

Target- A drug target is a biological molecule, often a protein, that is inherently linked to a certain disease process and that a medication might target to have the intended therapeutic effect.

Paralleling technique- The parallel method is the alignment of the central axis of the X-ray source so that it is perpendicular to both the plane of the film and the object being investigated. Unfortunately, it is considerably simpler to align the X-ray central axis perpendicular to the film than to the object.
