Each enzyme has a temperature at which it works best. A slight increase in temperature can increase enzyme activity while a larg

e increase in temperature can cause the enzyme to become denatured. Which of the following best explains what happens when a protein becomes denatured?
a. The enzyme absorbs heat until the temperature decreases, and the reaction then continues normally.
b. The enzyme loses its shape and is no longer able to catalyze chemical reactions.
c. The enzyme breaks apart into the amino acids that originally combined to form the enzyme.
d. The enzyme unfolds and refolds into a different shape, and is used to catalyze a different chemical reaction.

The correct option is B.
The shapes of enzymes are very important because their shapes determines the kind of chemical reactions that they can catalyse. This is because the substance been catalyzed must fit into the active sites of the enzyme that is been used. In a situation where an enzyme becomes denatured, such an enzymes losses its original shape and this remove from it the capacity to catalyze chemical reactions, thus, it becomes non functional.

Each segment of lung tissue is divided into a number of ____ wrapped in elastic connective tissue with a lymphatic, an arteriole
Luda [366]
<h3><u>Answer;</u></h3>

Lobules

<h3><u>Explanation;</u></h3>
  • In respiratory system the lungs are two spongy, cone shaped organs in the thoracic cavity and are separated from each other by the heart and other structures found in the mediastinum.
  • Deep grooves called fissures divide each lung into lobes. Each lobe receives its own secondary bronchus. Each lung lobe is divided into smaller segments that are supplied by a tertiary bronchus.
  • <em><u>The segments, in turn are subdivided into small compartments called lobules, which contains, lymphatic vessel, arteriole, venules and also a branch from terminal bronchiole wrapped in elastic connective tissue.</u></em>

Mrs. Fender's jaundice is caused by the accumulation of bilirubin in her blood and tissues. What is the normal fate of bilirubin
vfiekz [6]

Answer:

Jaundice is a symptom of cirhosis which is related to the chronic liver disease

Explanation:

Bilirubin is produced in the body when the hemoglobin protein in old red blood cells is broken down. Erythrocytes continuously undergo a (breaking apart) process.  As the red blood cells disintegrate, the hemoglobin is degraded or broken into globin (the protein part), iron, and heme. The heme first breaks apart into biliverdin, a green pigment which is immediately reduced to bilirubin, an orange-yellow pigment. The bilirubin is then transported to the liver where it reacts with a solubilizing sugar called glucuronic acid. This more soluble form of bilirubin (conjugated) is excreted into the bile. The bile passes through the gall bladder then goes into the intestines where the bilirubin is converted into a variety of pigments.

Jaundice occurs when the diseased liver doesn't remove enough bilirubin, a blood waste product, from your blood. Cirrhosis, when in its late stages, can cause Jaundice. Cirrhosis occurs as a result of severe scarring of the liver caused by chronic liver disease. As a healthy liver tissue becomes damaged over time, it is replaced by scar tissue, which affects the structure of the liver and decreasing its ability to function.

The actual niche the organism is able to occupy in the presence of competitors is called its:_____________.
ladessa [460]

Answer:

B) realized niche

Explanation:  

The ecological niche refers to all the environmental factors that influence the growth, survival, and reproduction of species. These factors also include the interaction between species. The term ecological niche refers to the fundamental niche or the realized niche.    

  • The fundamental niche refers<u> only</u> to factors or physical conditions under which a species can live and survive in the <u>absence of any interaction with other species. </u>
  • The realized niche refers to the restricted conditions in which a species can live and survive as a result of <u>environmental conditions and the interaction with other species</u><u>. </u>

When an inferior competitor is excluded by the superior competitor, this is known as competitive exclusion. This occurs when there is not habitat differentiation, and both species can not share the same niche. In this case, the effective or realized niche of the dominant species completely occupies the fundamental niche of the inferior competitor.        

 In the exposed example the organism is able to occupy a niche in the presence of competitors, which is the clue for us to classify this niche as a realized niche. The organism needs to interact in a certain way with its competitors. There is an interaction between taxonomic groups, or between individuals.
