When the entire group of forces acting on an object is balanced, the vector sum
of the forces is zero, and the effect of the group of forces on the object's motion
is identical to the effect of no force at all. The object continues in constant uniform
motion.
To state the outcome of the situation in three different ways:
-- The object's acceleration is zero.
-- The object's velocity is constant.
-- The object's speed and direction of motion don't change.
The direct answer to the question is: Nothing happens to its motion.
<h3><u>Answer</u>;</h3>
Key
A sorting device that is useful in classifying by observation is a <u>key</u>.
<h3><u>Explanation</u>;</h3>
- <em><u>Classification key or taxonomic key is a device that is used by scientists to identify unknown organisms. </u></em>
- They are constructed so that the user gets a series of choices about the characteristics of the unknown organisms.Thus, by making the correct choice at each step, one is led to the identity of the specimen.
- Therefore<u><em>, keys can be used to identify a living organism or determine which group it belongs to</em></u> by answering questions on the key about characteristics of living things.
Answer:
Parts of a homogeneous mixture are evenly mixed
Explanation:
A homogenous mixture is a mixture in which two or more substances are evenly mixed but not bonded together.
This is a homogeneous mixture, or a solution.
I hope this helped :)
Answer:
D.
Explanation:
•Specific enzymes catalyze each cellular reaction in cellular respiration. The main role of enzymes during the respiration reaction is to assist in transferring electrons from one molecule to another.
•The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.
ENZYMES ARE REQUIRED FOR MOST OF THE CHEMICAL REACTIONS THAT OCCUR IN ORGANISMS
