DNA- Deoxyribonucleic Acid is a molecule composed of two chains or double strands that coil around each other forming a double helix to carry the genetic information for the development of an organism.

<u>Explanation:</u>

  • DNA contains the information that instructs a living organism to develop, grow, survive and reproduce.
  • The information instructed is found inside every cell and is passed down from parents to their children.
  • DNA is made of nucleotide molecules which in turn contains a phosphate group, a sugar group, and a nitrogen base.
  • Deoxyribose in DNA is another form modified from ribose sugar.

How do non green leaves photosynthesize
Dafna1 [17]
Basically six molecules of water (H2O) plus six molecules of carbon dioxide (CO2) in the presence of light energy produce one molecule of glucose sugar (C6H12O6) and emit six molecules of oxygen (O2) as a by-product. That sugar molecule drives the living world. Animals eat plants, then breathe in oxygen, which is used to metabolize the sugar, releasing the solar energy stored in glucose and giving off carbon dioxide as a by product

A macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.

<h3>What is endocytosis?</h3>

Endocytosis is a cellular process by which a cell can absorb materials from the surrounding medium, such as viruses and bacteria in the case of macrophages.

Microfilaments and microtubules are proteins that form part of the cytoskeleton and dynamic conformational changes of them are associated with the cytoskeletal rearregement during the phagocytic process.

The actin microfilaments in the membrane and microtubules in the cytoskeleton form part of the process of endocytosis because they need to reorganize during cell movement.

In conclusion, a macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.
