Why is mitosis important to understand

Biology
1 answer:
blagie [28]4 years ago
6 0
Mitosis is important because this is the stages (cell cycle) in a cell where the chromosomes are split into two and have their own nucleus. There are seven stages to this process

1. Interphase
2. Prophase
3.Prometaphase
4.metaphase
5. Anaphase
6. Telophase
7. Cytokinesis

In most cases, mutations in the core of a protein that replace a smaller nonpolar side chain in the wild-type (e.g., Ala, Val) w
aivan3 [116]

Answer:

The correct answers are:

  • The protein core is hydrophobic in nature.
  • Mutation disrupts the hydrophobic interactions between the non-polar amino acids in the core of the protein thereby destabilising its structure.
  • Filling the blanks: non-polar, hydrophobic, large, Van der Waals contacts, Van der Waals contacts.

Explanation:

  • The core of a protein is rich in non-polar amino acids like alanine, valine, leucine, etc.
  • These amino acids are capable of interacting with each other by the formation of weak Van der Waals contacts with each other.
  • Van der Waals forces can be defined as the force of attraction between atoms or molecules when they are in close vicinity with respect to each other.
  • The proper folding of a protein requires the proper positioning of each of the side chains of the amino acids in both the interior as well as the exterior of the protein.
  • Mutation causing the replacement of a short chain non-polar amino acid with a long-chain non polar amino acid in the protein core requires more space for the long chain non-polar amino acid. This disrupts many Van der Waal forces of interaction among other non-polar amino acid side chains  in the interior of the protein.
  • This ultimately distorts the entire folding pattern of the protein causing its destabilisation and mis-folding.

A water treatment plant needs to maintain the ph of the water in the reservoir at a certain level. To monitor this
Setler [38]
<h2>Maintained of Water </h2>

Explanation:

  • pH is a proportion of the measure of Hydrogen particles (H+) even in unadulterated water particles will in general structure because of irregular procedures (creating some H+ and OH-particles).
  • The measure of H+ that is made in unadulterated water is about equivalent to a pH of 7. That is the reason 7 is neutral.
  • A repository can likewise be shaped from a characteristic lake whose outlet has been dammed to control the water level.
  • The dam controls the measure of water that streams out of the repository.  
  • <em>Expanded fluctuation and power of precipitation because of environmental change is relied upon to create both progressively extreme dry spells and flooding, with possibly genuine ramifications for water supply and pollution from combined sewer overflows.</em>

(06.02 MC) Which of the following correctly explains the role of antibiotics in the human body? (2 points) a They break down dam
aksik [14]

Answer:

The beneficial role of antibiotics in the human body is given because they produce rupture the cell wall or prevent protein synthesis in bacteria.

Explanation:

Antibiotics are a group of drugs that fight bacteria, eliminating them, to cure infectious diseases.

The mechanisms of action of antibiotics aim to break the bacterial protection or interfere with their vital functions to make them unviable:

  1. Destruction of the bacterial wall or membrane.
  2. Interference with protein synthesis.
  3. Inhibition of the synthesis of nucleic acids.

In general, the effects of antibiotics on bacteria are to rupture the cell wall or prevent protein synthesis. Through these mechanisms, antibiotics eliminate and prevent the reproduction of pathogenic bacteria, thus eliminating the infections they produce.

The other options are not correct because:

<em>     a. Breaking down damaging toxins created by bacteria is an anti-toxin function.</em>

<em>     b. Antibiotics do not increase the number of white blood cells in the blood. </em>

<em>     d. Reduction of the effects of fever, swelling, and inflammation in the body is a function of antipyretics and anti-inflammatories.</em>
