Answer:how am i supposed to answer?
correct answers are:
Salad dressing is an example of a homogeneous mixture. - False
The simplest type of substance is a compound. - False
When elements combine to form compounds, their properties do not change. - False
The chemical symbol for water is H20. - False
Substances in a mixture keep their own properties. - True
The substances in a heterogeneous mixture can usually be seen and are easily separated. - True
Salad dressing is typically a heterogeneous mixture. It consists of various ingredients, such as oil, vinegar, herbs, spices, and sometimes other additives. The simplest type of substance is an element, not a compound. An element consists of only one type of atom and cannot be broken down into simpler substances by ordinary chemical means. When elements combine to form compounds, their properties often change. Compounds have unique chemical and physical properties that are different from the properties of the individual elements that compose them.The chemical symbol for water is H2O, not H20. In a mixture, the substances retain their individual properties. They do not chemically combine or react with each other. In a heterogeneous mixture, the components are not uniformly distributed and can often be seen as distinct phases or particles.

Surface winds tend to curve due to which of the following?
a.
The Corona effect
b.
The Coriolis effect
c.
The Corolla effect
d.
None of the above
Answer:
B.
Explanation:
The rotation of Earth causes moving fluids to appear to move east to west in the southern hemisphere and west of east in the northern hemisphere in a phenomenon known as the Coriolis effect. The curve of Earth's surface means that solar waves hit Earth at different angles.

desertification?
allow livestock to overgraze the pasture
remove trees and other natural vegetation
overwater the ground causing soil erosion
rotate different crops that are grown each season
Answer:
d. rotate different crops that are grown each season
Explanation:
because different crops need different recources and that gives it a break its the only reasonable answer
allow livestock to overgraze the pasture makes zero sense and would make the problem much worse
remove trees and other natural vegetation would also hurt the environment
overwater the ground causing soil erosion its better but would do nothing to aid in the goal

Explain why a change in extracellular Na did not alter the membrane potential in the resting neuron.
Answer:
Explanation:
A change in extracellular Na did not alter the membrane potential in the resting neuron because the plasma membrane of a neuron is composed of little Na+ leakage channels and it is slightly permeable to few Na, thus lead to reduction in diffusion if Na inside and outside the cells.
Which statement explains the effect of an inhibitor on an enzyme?
A.The enzyme will be unable to produce more enzymes.
B.a substrate will be unable to attach to the enzyme.
C.a substrate will be able to bond with the enzyme.
D.The enzyme will likely be attacked by immune cells.
Answer:
D
Explanation:
The statement that is explaining the effect of an inhibitor on an enzyme is that a substrate will be unable to attach to the enzyme. The correct option is B.
What is inhibitor?A reaction inhibitor is a compound that slows or precludes a chemical reaction. A catalyst, on the other hand, is a material that accelerates a chemical reaction.
An enzyme inhibitor is a molecule that unites to an enzyme and prevents it from working.
Enzymes are proteins that accelerate chemical reactions that are vital to life, such as the conversion of substrate molecules into products.
Cimetidine, erythromycin, ciprofloxacin, and isoniazid are illustrations of enzyme inhibitors.
Small molecule inhibition of enzymes is a significant control mechanism in biological systems.
This is a common drug discovery strategy that can provide a better understanding of enzyme activity, for example, by identifying residues critical for catalysis.
Thus, the correct option is B.

What characteristics describe the solutes in the NaCl solutions in this activity?
Select all that apply:
-small
-large
-non-polar
-polar
-ionic/charged
(Select two)
Answer:
Ionic
Polar
Explanation:
Normally the NaCl is ionic and polar.
It is polar because of the large difference in the electronegativity of the Na and CL.
It is also ionic because it forms ions in the solutions and combines with other ions to form an acid or a base.
When NaCl is mixed in water the following reaction takes place
NaCl + H₂O⇒ NaOH +HCL
NaOH is a base and HCL is an acid. Usually by combining a salt and water an acid and a base is obtained.

witch side of photosynthesis formula contains reactants
Answer:
The reactants of photosynthesis are water, light and carbon dioxide, while the products are oxygen and sugars. A chemical equation is like a recipe for a reaction so it displays all the ingredients or terms of a chemical reaction.
In a chemical formula, the reactants are on the left side of the arrow, and the products are on the right. First, photosynthesis provides the energy that is used by all other organisms to survive.

define the term osmosis and how it works
Answer: Osmosis is the spontaneous net movement of solvent molecules through a selectively permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides. It may also be used to describe a physical process in which any solvent moves across a selectively permeable membrane (permeable to the solvent, but not the solute) separating two solutions of different concentrations.

Which of the following is NOT a term related to groundwater?
permosity
the zone of saturation
pore
water table
This is science BTW
Answer:
Permosity
Explanation:
Groundwater is defined as the water that is found inside the surface of the Earth. It comes from both rain, fractures of rock formation and melting snow.
Some examples of groundwater include aquifers, springs, wells, etc.
The term that is not related to groundwater is permosity.
Permosity is the term that isn't related to groundwater. Groundwater are
usually found in between rocks and soil as a result of it seeping through the
floor during precipitation.
The following are related to groundwater and they include:
Zone of saturation is found below the water table in which the rocks and soil are saturated with water. Pore refers to the tiny spaces in the soil and rocks which the water seeps through.Water table refers to the upper ground boundary which the soil are permanently saturated with water.This makes Permosity to be the most appropriate choice out of the list of
options provided.

A student proposes that when burning isopropyl alcohol (C3H8O) - the same TWO products will be made as when they burned ethanol in class.
1a. What PRODUCTS should she expect to have and what EVIDENCE should she expect to observe or measure to show that those two products were formed?
Your answer should have TWO products (what comes OUT after burning isopropyl alcohol), and what could be observed in an experiment to provide evidence that each of those came out.

Answer:

Explanation:
The equation for the combustion of isopropyl alcohol is shown below;
C3H8O+9/2 O2→ 3CO2+4H2O
Now our task is to carry out a simple test to confirm that both carbon dioxide and water vapor are products of the reaction.
Test for CO2:
If the products of the reaction are bubbled into lime water, the lime water gradually turns milky. This confirms the presence of CO2 as one of the products of the reaction.
Test for H2O:
If the products of the reaction are passed over white anhydrous copper II sulphate, the anhydrous crystals turn blue to show that water is present.
