What is a single celled organism called
Options- A. protoctists
- B. chromosomes
- C. unicellular
- D. bicellular
- Correct Answer
- unicellular
ExplanationAn organism is a living thing, and there are two broad categories of organisms: those made up of only a single cell, and those made up of multiple cells.
Single-celled organisms means which contains only one cell are called unicellular organisms. 'Uni-' means 'one,' so the name 'unicellular' literally means 'one cell.'
Examples of Unicellular or Single celled organisms ::
Prokaryotic organisms like Bacteria,...
Some algae like green algae, euglena,...

Correct Answer: 120/80 mmHg
Explanation:
Healthy blood pressure ranges from 120/80 to 90/60.
Correct Answer: Phospholipids
Explanation:
Cell membranes are made up of phospholipids which prevents them from dissolving in water.
Correct Answer: charophytes
Explanation:
The charophytes are the extant group of green algae that are most closely related to modern land plants.
Correct Answer: a surface exposed by a retreating glacier
Explanation:
Primary succession is the orderly and predictable series of events through which a stable ecosystem forms in a previously uninhabited region. Primary succession occurs in regions characterized by the absence of soil and living organisms.
Correct Answer: Reactivity
Explanation:
The ability of two or more substances to combine to form other substances is called Reactivity.
Correct Answer: 1) If they use the same cutting board/counter to cut raw chicken, and other foods with out sanitizing in between 2) If they have a cold, flu, or pink eye and are handling food, coughing without covering their mouth, then washing their hands 3) If they don't properly wash their vegetables 4) Not storing foods at proper temperatures And so many other reasons for Food handlers can contaminate food
Correct Answer: J. E. Purkinje
Correct Answer: decreases
Explanation:
When water is cooled from 4°C to 0°C, its density decreases.
When water cools from 4°C to 0°C, ice crystals begin to form because the water is approaching its freezing point. When water freezes, the water molecules form a lattice that increases the volume. As a result, the density decreases. This is why ice will float on top of water; ice has a lower density than the water.
Correct Answer: Humidity
Explanation:
The amount of water vapor in the air is called Humidity. The amount of water vapor that air acn hold depends on the temperature of the air. The amount of water vapor in the air as compared with the amount of water that the air could hold is called Relative humidity.
Correct Answer: All of the above
Explanation:
Glycolysis involves the breaking down of a sugar into more manageable compounds in order to produce energy.
The net end products of glycolysis are two Pyruvate, two NADH, and two ATP.
