A trisomy is a chromosomal condition characterized by an additional chromosome. A person with a trisomy has 47 chromosomes instead of 46.

Trisomy means the presence of an extra chromosome in some or all of the body's cells. This results in a total of three copies of that chromosome instead of the normal two copies. For example, Down syndrome (trisomy 21) is caused by having three copies of chromosome 21 instead of the usual two copies.

This genetic condition is the result of a genetic mutation where your cells don't divide as they should. You can't prevent this abnormality from happening during cell division.

<span>D. Vascular tissue
</span>
Vascular tissue is responsible for transporting water and nutrients in plants. <span> The Vascular tissue consists of the Xylem and the Phloem. The main function of the Xylem is to transport water and minerals throughout all parts of the plant. Phloem on the other hand is responsible for transporting organic molecules that are larger in size. The vascular system, consisting on the Xylem and the Phloem runs from the roots of the plats through the branches and upto the leaves. It controls the total transportation of the water and nutrients.</span>

Assoli18 [71]

Answer: C. Microfilaments

Explanation: Microfilaments, also called actin filaments, are protein filaments in the cytoplasm of eukaryotic cells that form part of the cytoskeleton. They are primarily composed of polymers of actin, but are modified by and interact with numerous other proteins in the cell. Microfilaments, or actin filaments, are the thinnest filaments of the cytoskeleton and are found in the cytoplasm of eukaryotic cells. The polymers of these linear filaments are flexible but still strong, resisting crushing and buckling while providing support to the cell.

This is done through meiotic division.

Why is the archaea domain closer to eukarya than bacteria?
harkovskaia [24]

Answer:

Archaea domain is closer to eukarya than bacteria because genetically they are more similar to Eukarya than Bacteria.

Explanation:

Options for this question are:

  • <em>They both lack a nucleus and contain  cytoplasm. </em>
  • <em>The unique functional adaptations of Archaea are more similar to Eukarya adaptations.  </em>
  • <em> They both evolved in the same geological time period. </em>
  • <em> </em><em>Genetically, the Archaea are more similar to Eukarya than Bacteria. </em>
  • <em> They both have membrane-bound organelles. </em>
  • <em> Archaea is not closer to Eukarya because it contains prokaryotic cells just like Bacteria.</em>

Archaea are unicellular prokaryotic organisms, which share many characteristics with bacteria, however, the existence of metabolic functions and genes similar to eukaryotic organisms suggest that there is a genetic link between the two. Even the enzymes responsible for genetic processing, such as transcriptases and translation enzymes, are similar to those in eukaryotic cells.

The theory that establishes the relationship between Archaea and Eukaryotic suggests the existence of a common ancestor, whose later evolution allowed an Archaea to join a protobacteria to form a eukaryotic cell, and hence their genetic relationship.
