The statement which is an inference is; "the velocity of the stream is greatest near the outside of a meander."
The scientific method involves observations, hypothesis, experimentation and inference. The inference is a conclusion arrived at after conducting an experiment.
Hence, an inference is not a futuristic statement or a prediction but a statement of fact as gathered through the scientific study. The statement which represents an inference among the options is; "the velocity of the stream is greatest near the outside of a meander."

The true about element in period or horizontal row of periodic table is
Each element has one more outer electron than the element before it. (answer B)
<u><em> Explanation</em></u>
In periodic table there are four horizontal rows(periods) that is period 1,2,3 and 4.
Across the period each element has one more electron than element before it.
For example Na and Mg which are in periodic 3.
Na has 2.8.1 or [Ne] 3s¹ electron configuration while Mg has 2.8.2 or [Ne] 3S² electron configuration.
Since Mg has 2 outer electrons while Na has 1 outer electron, Mg has more electron than Na.
<span>Molality(m) or molal concentration is a measure
of concentration and it refers to amount of substance in a specified amount of
mass of the solvent. Used unit for molality is mol/kg which is also
sometimes denoted as 1 molal. It is equal to the moles of solute (the substance
being dissolved) divided by the kilograms of solvent (the substance used to
dissolve).</span>
Molarity(M) or molar concentration is also a
measure of concentration and represents the amount of substance per unit volume
of solution(number of moles per litre of solution. Used unit for molarity is
mol/L or M. A solution with a concentration of 1 mol/L is equivalent to 1 molar
(1 M).
Molality is preferred when
the temperature of the solution varies, because it does not depend on
temperature, (neither number of moles of solute nor mass of solvent will be affected
by changes of temperature), while molarity changes as temperature changes(volume
of solution changes as temperature changes).
I think the answer is
“Mushroom and algae are part of the fungi group”
