Mixtures are combinations of several substances. Each of the substances retains its physical properties. There are no new substances created. This is in contrast to a chemical reaction in which two or more reactants make new products.
There are two types of mixtures. The first kind of mixture is a homogenous mixture. Homogenous mixtures are uniform in the ratio of the combination of substances. throughout. All solutions are homogenous mixtures. Colloids (such as mile) and suspensions are also homogenous mixtures, but their particle sizes are larger than the particles that make up a solution. This larger particle size makes colloids and suspensions appear murky or opaque.
The second kind of mixture is a heterogeneous mixture. Heterogeneous mixtures are not uniform throughout. A classic example of a heterogeneous mixture is a trail mix- every handful you grab will be slightly different. If a suspension is allowed to sit, then its large particles will settle to the bottom of its container. At this point, the suspension would be classified as a heterogenous mixture.
Answer:
<em>The labels <u>I-VII</u> represent the different stages of primary succession. I-bare rocks, II-pioneers (mosses, lichen, algae, fungi), III-annual herbaceous plants, IV-perennial herbaceous plants and grasses, V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.</em>
By focusing on the base and the ball...?
Answer:
parasitic
Explanation:
when species 2 population is higher, species 1 is lower, meaning that species 2 harms species 1.
Answer:
C. A dead organism
Explanation:
A body is said to be in equilibrium if there is no likelihood of a change with relation to time. This also means that there is no detectable change in such a system.
However in relation to Biology a body is said to be equilibrium when it is dead. The metabolic state of the organism is usually zero and in a state of rest. There is absence of internal and external biochemical activity. Having life in carrying out cellular activities is the main determinant in the equilibrium state of an organism.
