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

produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria

<h3><u>Explanation;</u></h3>
  • Secretions from the highlighted glands <em><u>produce a layer of enzyme laden mucus that captures dirt and destroys inhaled bacteria </u></em>
  • <em><u>During inhalation airt that contains dust particles or bacteria or other microorganisms may enter the air ways. </u></em>
  • <em><u>The layer of the airway covering the airways, is rich in antimicrobial compounds and mucins that are responsible for removal bacteria and other microorganisms from the airway .</u></em>
  • <em><u>This layer consist of mucus that traps, kills, and also inactivates the bacteria. </u></em><em><u>It also contains periciliary fluid which keeps mucus at optimum distance from the underlying epithelia, to enhance bacteria clearance and  the motility of cilia.</u></em>

Describe how mitosis and cell differentiation leads to the creation of red blood cells in the body from bone
Alina [70]

Mitosis and cell differentiation leads to the creation of red blood cells in the body from bone  marrow stem cells by a process called Erythropoiesis.

<u>Explanation</u>:      

The process of development of red blood cells from bone marrow stem cells is called as erythropoiesis. The process is enthused by lower amount of oxygen during circulation, which is sensed by the kidney, after which it starts secreting a hormone called erythropoietin. In production of RBCs, the erythropoietin provokes the development and differentiation. All this phenomenon happen inside the Bone marrow.

You have just sequenced a new protein found in mice and observe that sulfur-containing cysteine residues occur at regular interv
Ronch [10]

Answer: Cysteine residues are involved in disulfide bridges that helps to form tertiary structure in a protein

Explanation:

The tertiary structure of a protein will have a single polypeptide chain backbone with protein secondary structures. The interactions and bonds of the side chains within a protein determine its tertiary structure.

<u>The cysteine forms the disulfide bridges and they link the fragments within a polypeptide chain</u>. Sometimes those fragments are located very far from each other with respect to their primary structure. So, the tertiary structure is the three dimensional shape of a protein.
