When a pathogen enters the body, cells in the blood and lymph detect the specific pathogen-associated molecular patterns (PAMPs) on the pathogen's surface. The immune system can be activated by a lot of different things that the body doesn't recognize as its own. These are called antigens. Examples of antigens include the proteins on the surfaces of bacteria, fungi and viruses. ... Sometimes the immune system mistakenly thinks that the body's own cells are foreign cells. Antigens are proteins that are found on the surface of the pathogen. ... The antibodies destroy the antigen (pathogen) which is then engulfed and digested by macrophages. White blood cells can also produce chemicals called antitoxins which destroy the toxins (poisons) some bacteria produce when they have invaded the body.

hope this helps :))

<h3>What is Regional Anatomy?</h3>
  • The shapes, locations, and relationships of the human body's structures in a particular region are the subject of regional anatomy.
  • One of the fundamental building blocks of safe and effective medical practice is a thorough understanding of regional anatomy.
  • After finishing this course successfully, students should receive knowledge of the major anatomical divisions, such as those of the thorax or upper limb, with an emphasis on the interactions between the numerous systemic structures (such as the muscles, nerves, and arteries) found there.
  • Understanding the morphological function of the various body regions in relation to one another and the body as a whole.
  • The capacity to employ regional anatomical knowledge to comprehend the underlying anatomical causes of actual biological issues.

Which statement provides a possible explanation for the growth
Shtirlitz [24]

Answer:

<u>3) Uncontrolled cell division occurred as a result of gene mutations</u>

<u />

Explanation:

Spontaneous modifications within the genome may occur during the process of cell division. When copies of the DNA inside the cell are made, these mutations cause errors; and can include small single nucleotide polymorphisms, and large scale additions or deletions across multiple genes.

Some, like somatic mutations, exist only inside vegetative (body) cells, that cannot be passed onto offspring. This is caused by several factors like

  • UV radiation,
  • chemical mutagens,
  • infective agents

UV radiation damages strands of DNA, by causing dimers to form; here, consecutive nucleotide bases covalently bond instead of those on the complementary strand. This conformational change causes errors in DNA proofreading and repair mechanisms where bases are not well-incorporated into the strand- tumors (clumps of uncontrolled cell growth) may form, resulting in melanoma, a type of skin cancer.

Kaylee is making a poster to show changes that happen in nature during winter in northern
kari74 [83]

During the winter season, the tree branches get dormant.

<u>Explanation:</u>

As the winter season starts, many plants show very slower metabolism that is the growth of the plants become very slow.

During the winter, there is very low amount of sunlight that the plants receive and so the synthesis of chlorophyll by the plants also in very small amount, and so there is least amount of sugar to metabolize by means of a slower Photosynthesis.

These tree branches become dormant during winter season, and it is mostly covered with the scales.
