Answer:
They are intermediate hosts.
Explanation:
Disease-transmitting insects are called vectors.
The life cycle of disease-causing pathogens is closely linked to the biology of the insect that carries it.
The symptoms of gongylonemiasis include hemorrhagic inflammation at the site the pathogen invades, followed by granulomatous tissue development that produces nodules in the invaded organ.
Some diseases transmitted by insects occur in both humans and other mammals because our differences in anatomy and physiology are not very different.
It is unlikely that clinical symptoms will occur in humans if the insect were the definitive host, because our biology is quite different from their biology, and the pathogen would be adapted to fulfill its entire life cycle in their body.
Answer:
1. The Central Dogma refers to the molecular process by which the DNA is converted into proteins using RNA as intermediate, i.e., DNA (Transcription)-> RNA (Translation) -> Protein.
2. Localization:
Transcription: within the cell nucleus (in eukaryotic organisms)
Translation: cytoplasm
3. Enzymes :
Transcription: RNA polymerase
Translation: Peptidyl transferase
Explanation:
Transcription is the process by which a segment of DNA (called gene) is used as template to synthesize a messenger RNA (mRNA) by using a specific RNA polymerase enzyme. During translation, this mRNA travels from the cell nucleus to the ribosomes in the cytoplasm, where this sequence (mRNA) is used as template to synthesize a protein. The ribosomes are organelles composed of ribosomal RNA (rRNA) molecules which direct the catalytic steps of protein synthesis, while transference RNAs (tRNAs) are molecules that act as adaptors which link the mRNA template with the corresponding amino acids being incorporated into the protein. The enzyme peptidyl transferase catalyzes the formation of peptide bonds between adjacent amino acids.
I think it is because the cold air is more dense than the hot air so the less dense air which is the warm air rises
Answer:
Molecules that are not soluble in water are fats and non-polar molecules . During their digestion and absorption in the small snall intestine, fats are packaged into hydrophilic form.
Explanation:
This explains the digestion of fats in the small intestine. This takes place in the illeum.( the longest part of 3.5 m) Bile salts from the liver, emulsified these fats, covering then with layers,while enzymatic action by lipase, from the pancreases, completes the process.
These fatty substance formed are called Micelles.In the intestinal cells, the micelles are covered by protein and lipids to aid transport in water medium of the intestine.A this sage they are called (lipoprotein).
They are absorbed in the lacteal- the lymphatic capillaries , unlike protein and CHO which are absorbed directly in the blood stream.I
They are finally absorbed into the blood stream via the lymphatic vessels.
Lipids are consisted of alcohol glycerol and usually 3 fatty acids
