Answer:
A scientist discovers a new organism in run-off from the Rio Tinto River in Spain (the river runs through a copper mine and the water has a pH of 2.0). On basic microscopic examination and after conducting a few simple experiments, she finds that this single-celled species is heterotrophic, has no cell wall, uses a flagellum for motion, and contains a variety of internal structures that are bound by plasma membranes. Given this information, this new species is most likely a <u>eukaryotic</u> cell in the <u>protozoan</u> subcategory
Explanation:
Eukaryotic cells contain nucleus and organelles and are enclosed by a plasma membrane. Organism that have these cells are protozoa, fungy, plants and animals.
Protozoan are single-celled eukaryotic.
The four sensations detected by the tactile receptors in the skin are touch, pressure and vibration and tickle.
<h3>What are the 4 sensations that the receptors found in the skin have?</h3>
They are nerve endings formed by a branched axon. They are distributed in almost all parts of the body and capture mechanical (pressure), thermal (cold and heat) and especially painful sensations.
This is because Tactile sensations are the ones that detect touch, pressure, and vibration. About six different types of tactile receptors are known.

The cenozoic era is the geological era that mammals expanded on earth
When microscope slides are stained to show blood cells, the small red blood cells that appear on the slides are much more numerous than the large white blood cells. I believe this supports the fact that each kind of cell is present in the numbers best suited to meet the needs of the body. In other words it supports the concept of having normal blood. Red blood cells as compared to the white blood cells are really more numerous. In normal cases, human blood contains about 3.6 to 6.2 trillion/ L red blood cells while white blood cells only reaches 5 to 10 billion per Liter.
