Answer:
D) None of the above
Explanation:
Arthropods are characterized by the possession of an exoskeleton and a segmented body. This group includes insects, arachnids, myriapods (centipedes and millipeds), and crustaceans.
The Devonian period, belonging to the Paleozoic Era, occurred from around 415 million to 350 million years ago. During this era, arthropods such as centipedes, millipedes, and flightless insects were predominant and diversified throughout this period.
Therefore, as all of these arthropods were present in the Devonian period, the correct answer is <u>d) None of the above</u>.
<h2>Answer:</h2>
As in a given cross two genes control the height and flower color. Tall height (T) is dominant over the short height (t) and yellow flowers (Y) are dominant over the white flower (y).
When the tall yellow flowered mated with short white flowers, the genotype of the plants can be;
TTYY × ttyy or It can be TtYy × ttyy or TTYy × ttyy or TtYY × ttyy
They can all make you ill and be dangerous for the body
Cell saps are the liquid inside of a plant cell's large central vacuole, which acts as support in order for it to function. They're made up of amino acids, glucose, salts and water and plays an important role in osmosis.
Cytoplasms, on the other hand, are a jelly-like substance between the cell membrane and nuclear envelope within a eukaryotic cell. They're mostly made up of water and salt, and aid in growth and metabolism in a cell.
