Consider the following prediction. Prediction: If an increase in temperature increases the rate of evaporation of
water, then an increase in average daily temperatures will decrease lake water
levels over a two-year period.
Which of the following best describes this prediction?
A. The prediction is not useful because scientists are skeptical of
anyone who claims to see into the future.
O B. The prediction is useful because it proves that the hypothesis is
true before any data have been collected.
O C. The prediction is useful because it specifies what observations
will be made to test a hypothesis.
O D. The hypothesis is not useful because it is too long as a sentence
and therefore difficult to read.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
