Answer:
Liquid and with a higher osmotic pressure
Explanation:
Remember that a cell that is surrounded by an environment with a higher osmotic pressure, will produce that the cell get some water outside to make some dilution to the salt concentration that surrounds the protozoan.

Answer:
What is the difference between the terms Matter and Element?
- Anything that occupies space and has mass is called matter. It can be solid, liquid or gas.
- Element is smallest classification of matter, which cannot be sub-divided into simpler components by chemical means.
What is an atom?
- An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
What are the 4 most common atoms to the human body?
- The four most abundant elements in the human body – hydrogen, oxygen, carbon and nitrogen – account for more than 99 per cent of the atoms inside you. They are found throughout your body, mostly as water but also as components of biomolecules such as proteins, fats, DNA and carbohydrates.
What are molecules?
- A molecule is an electrically neutral group of two or more atoms held together by chemical bonds. Molecules are distinguished from ions by their lack of electrical charge.
What is a chemical reaction?
- A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.
According to the Rules of Atoms, will the carbon in carbon dioxide be around in a million years? How likely is it the carbon dioxide molecule will be around? What is your reasoning?
I don't know, this one you can answer yourself
Explanation:
Hot and Dry
Hot and dry deserts, such as the Sonoran Desert
of Arizona and northwestern Mexico, are warm year-round with an extreme
range of diurnal (daily) temperatures because of low humidity. Brief but
heavy storms may occur seasonally. Soil is hard and rocky. Burrowing
mammals, insects and reptiles are the main fauna. The Great Sandy Desert
of Australia and the Sahara of north Africa fall under this category.
Semi-Arid
Semi-arid
deserts, such as the Great Basin of Nevada and western Utah, have long
dry summers plus winter rainfall. Dew fall may exceed rainfall. Soil is
sandy and rocky, and may include “caliche” (pans of calcium carbonate).
Fauna is consistent with hot and dry deserts.
The stimulus and response when a human increases his/her physical activity
<h3>What is stimulus?</h3>
- A stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment.
- The ability of an organism or organ to detect external stimuli, so that an appropriate reaction or response can be made, is called sensitivity
When a human increases physical activity, the amount of fuel burned in its cells also increases, which in turn increases the concentration of dissolved CO2 in the blood. The CO2 reacts with water in the blood to make a weak acid, which lowers the pH of the blood.
