Answers

Answer 1

Complete question:

Experiment 1: Mold Growth on Bread and Fruit

The purpose of this experiment is to analyze the mold growth on bread and apple under different conditions.

After performing the experiment, the student must answer a sequence of questions. One of the questions is "What was the purpose of examining three pieces of bread and three pieces of apple in each treatment?​".

Answer:

The purpose of examining three pieces of bread and three pieces of apple is to obtain more precise results in the experiment, with the lower error possible.

Explanation:

Each piece of bread and apple is a replica.

In an experiment, replica refers to the repetition of the basic experiment. Each replica might be considered as a copy of other replicas, and its importance relies on getting a better estimation of the experimental error and obtaining a more precise response or answer to the question. The higher number of replicas in an experiment, the better results will be obtained.

Which of the following characteristics is shared by all modern living systems?
A. Multicellular body systems
B. Codons based on a triplet code
C. DNA as the genetic material
D. Sub-cellular organelles

Answers

Answer:

B-Condon's based on a triplet code

Expl

The characteristic shared by all modern living systems among the options provided is DNA as the genetic material. Therefore option C is correct.

DNA (deoxyribonucleic acid) is a molecule that carries the genetic instructions for the development, functioning, and reproduction of all known living organisms. It is a long, double-stranded helix structure composed of nucleotides.

Thus, DNA as the genetic material is a fundamental characteristic shared by all known modern living systems.

It encodes the instructions necessary for the development and functioning of an organism, allowing for the transmission of genetic information from one generation to the next.

. Describea typical stress-strain curve and the relationship between the segments of the curve and stress and strain.

Answers

Answer:

the relationship between stress and strain that a particular material displays . it's unique for each material . it's is found by recording amount of strss at different values of strain. it is the stress point at which a specific material breaks under a given stress  in a typical stress-strain curve ,  the breaking strength is less than the ultimate strength

Explanation:

The typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.

What is the significance of the stress-strain curve?

A typical stress-strain curve has several segments, including the elastic region, which represents the stiffness of the material, and the plastic region, which represents the point at which the material begins to permanently deform. Necking: a reduction in cross-section; ultimate strength, then a material's ability to deform until it reaches its ultimate strength, and so on.

Hence, the typical stress-strain curve and the relationship between the segments of the curve and stress and strain explain the relationship between these two as the Stress is the result of the force applied, and strain is the deformation of a material in response to stress.
