differences between the structure of the wall of the stomach and the structure of the wall of the ileum​

Biology
1 answer:
JulijaS [17]2 years ago
5 0

Answer:

Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.

wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.

Thepotemich [5.8K]
An animal body plan that is triploblastic and coelomate has three main layers of tissue during development.
<span>The germ layers are tissue layers which develop early in embryonic life, through the process of gastrulation. During gastrulation, a hollow cluster of cells-blastula reorganizes into two primary germ layers: an inner layer- endoderm, and an outer layer, - ectoderm which interact to produce a third germ layer - mesoderm. Together, the three germ layers will give rise to every organ in the body. For example, ectoderm will form skin, endoderm will form digestive tract and mesoderm will be involved in the formation of visceral organs like the stomach.</span>

Which of the following statements about magnesium atoms is NOT correct? 1. All magnesium atoms have the same number of protons.
Fantom [35]

Answer:

5. All magnesium atoms have the same number of neutrons

Explanation:

Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).

The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they  vary in the mass number of the atom (M).

The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.

Based on this information we can know how many neutrons each isotope has

24 Mg = 12 protones + 12 neutrons

25Mg = 12 protones + 13 neutrons

26Mg = 12 protones + 14 neutrons

In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>

Homework. Unanswered
Dennis_Churaev [7]

Gram-positive bacteria are bacteria that have thick cell walls which yield positive results in the Gram staining test. Lipoteichoic acid is a major component of the cell wall of gram-positive bacteria.

  • All bacteria indicated in the question can be classified by the Gram staining test:
  1. Actinomycetes are Gram-positive bacteria
  2. The genus <em>Arthrobacter </em>includes Gram-positive bacteria
  3. <em>Escherichia coli </em>(<em>E. coli</em>) is a Gram-negative bacterium
  4. <em>Staphylococcus spp.</em> are Gram-positive bacteria
  5. <em>Bacillus spp</em> are Gram-positive bacteria
  6. <em>Mycobacterium spp.</em> are Gram-positive bacteria

  • Prokaryotes can be divided into two domains: Bacteria and Archaea.

  • Gram staining is a method used to classify bacteria, but this method IS NOT USED to stain Archaea.

  • In consequence, I would not use the Gram test to stain Archaebacteria because Archaebacteria aren't bacteria (Option A is correct).

  • Archaebacteria belong to the Archaea domain.
