Biological surplus: this occurs when there are more organisms in a population than the ecosystem can sustain
Climax community: this is a point in an ecosystem when all populations reach a point of little or no change
Sigmoid phenomena: this is when a population increases while food and habitat are abundant and decreases as food becomes less available

<h3>What is ecology and what are some terms in ecology?</h3>

A gas with a volume of 500. mL at 75°C is heated to 225 °C. What is the new volume of the gas?

mihalych1998 [28]

Using v1/t1=v2/t2
v1=500
v2=?
t1=75=368k
t2=225=498
500/368=v2/498
1.4x498=v2
v2=697.2ml

Which phrases describe clastic sedimentary rocks? Check all that apply.

Romashka [77]

Explanation:

A clastic sedimentary rock is a rock that is formed from pre-existing rock materials and minerals. This materials have been transported to their new positions by the agents of denudation.

Clastic sedimentary rocks are made up of rock fragments predominantly.
The matrix is usually remnants of other rocks.
A cementing material can form between clasts and holds them in place. Cements are usually iron oxides, calcite e.t.c.
These rock types are usually formed from mechanincal weathering of rocks
Mechanical weathering breaks down rocks into chunks.
Examples are breccia, conglomerates, e.t.c.

When preparing the diazonium salt, the solution is tested with potassium iodide-starch paper. a positive test is the immediate f

Dahasolnce [82]

KI-starch paper allows the detection of strong oxidizers such as nitrite. It is used here to control diazotization of 4-nitroaniline. Nitrite oxidizes potassium iodide in order to form elemental iodine which reacts with starch to a blue-violet complex. With KI-starch paper, enough sodium nitrite is added to produce nitrous acid, which <span>then will react with 4-nitroaniline to form a diazonium salt.</span>
