Answer;
B. Group: 3rd and 4th hours, with values under the true density. Group: 1st, 2nd, 5th, and 6th hours, with values over the true density.
Explanation;
Accuracy refers to the closeness of a measured value to a standard or known value.
Accuracy is a qualitative term referring to whether there is agreement between a measurement made on an object and its true (target or reference) value.
B.The molecules of one substance break down in the other.
C.Different samples of a single mixture have different characteristics.
D.One substance can be separated from another through physical means.
Answer: The correct answer is D) One substance can be separated from another through physical means.
Mixture is a combination of two or more substances that are combined or mixed physically in a way that they do not loose their identity.
This means that mixture does not undergo any chemical change and it can be separated through physical means (like filtration). It can be of solid, liquid, or gaseous molecules.
Mixture can be primarily divided into homogenous ( having uniform composition that is every sample will have same property) and heterogenous mixture ( non uniform composition that is not every sample will have same property).
Thus, option D) is a property of every mixture.
b. cell membranes, cell walls
c. chloroplasts, nucleus
d. chloroplasts, cell walls
Answer:The constituents of a solid can be arranged in two general ways: they can form a regular repeating three-dimensional structure called a crystal lattice, thus producing a crystalline solid, or they can aggregate with no particular order, in which case they form an amorphous solid (from the Greek ámorphos, meaning

Explanation:
Genetic information is a information which is stored in cells of the living beings in the form of nucleic acids which can be either DNA (deoxyribonucleic acids) or RNA (ribonucleic acid). These nucleic acids store information in the coded form. These are passed from the parents to their offspring through reproduction. The ATP (adenosine triphophate) is the energy molecule present in the body after the oxidation and breakdown of food by the process of respiration. This does not carry the genetic information.
