Biology

Tresset [83]3 years ago
5 0
<h2>Nucleus - control center</h2>

The nucleus is called the control center of the cell because:

  • The genetic material which is the essence of life is hosted in the nucleus – the DNA-which presents the code of life or information or instructions regarding:
  1. The structure and function of each cell and the organ it is present,
  2. Numerous activities of life like reproduction, metabolism, growth, development, etc.
  • The nucleus replicates the genetic information and passes to the new daughter cells, generation after generation to continue the life processes.  
  • The nucleus DNA transcribes the code or information for protein synthesis to the RNA to synthesize proteins in the body which carry out many essential functions in the form of structural proteins, antibodies, hormones, pigments, etc.  
  • The nucleus DNA synthesizes enzymes which carry out functions like metabolism.

Describe accurately the the basement membrane which underlies epithelial tissues
Nady [450]

Answer:

The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

Explanation:

The basement membrane is the layer underlies all epithelia that is made up extracellular matrix secreted by the epithelium cells that provide structural support to the structure of epithelia.

It forms the barrier between epithelial tissues therefore once a epithelial cancer penetrate this basement membrane it will spread to all underlying tissues.

Thus, the correct answer is - The basement membrane or basal lamina on which the epithelium form, made by extracellular matrix.

The basement membrane is form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.

The basement membrane, or basal lamina, is a sheet of proteins and other substances to which epithelial cells adhere and that forms a barrier between tissues.

Epithelial cancers may have the ability to penetrate through the basement membrane and spread to underlying tissues.

Consider the functions of the kidney in the urinary system and the blood vessels in the circulatory system. what tissue type is
Bess [88]

Connective tissue is the type of tissue common to the blood in the circulatory system and kidneys in the excretory system.

Renal fascia and blood are two different connective tissues found in the excretory system and circulatory system respectively. All the connective tissues have a common origin, known to be mesodermal. Moreover, they connect two different body parts. Blood connects the body organs and the renal fascia in the kidneys connect the kidneys with the adrenal glands.

Functions of renal fascia and blood are as follows:

Renal fascia (alternatively called gerota's capsule or gerota's fascia) is surrounded by two layers of adipose tissue. The primary function of this tissue involves holding up these tissues and providing a firm hold to protect them from any injury caused by unexpected accidents.

Blood is composed of four main components, plasma, platelets, erythrocytes (RBCs), and leukocytes (WBCs). Some of its functions include:

● The primary function of blood is to supply oxygen to the cells, tissues, and organs in the body

● supplying nutrients and minerals to the body's organs

● removing carbon dioxide and other waste materials like lactic acid, and urea.

● helps in regulating body temperature

● helps in the clotting process during the time of any injury through the action of platelets

● helps in fighting against diseases and infection through the action of WBCs.

What is the atmospheric layer with the lowest density??
lubasha [3.4K]

Answer:

The Exosphere

Explanation:

The Exosphere is the farthest away from the Earth and the least dense. Going towards the Earth a space ship would pass through the Ionosphere, then the Stratosphere where high flying airplanes can be found, and finally closest to the Earth is the Troposphere which is the thickest layer where all our weather takes place.
