Answer:

Computer hardware is any physical device used in or with your machine, whereas software is a collection of codes installed onto your computer's hard drive.

Explanation:

as the best understanding we can say

Hardware refers to the physical and visible components of the system such as a monitor, CPU, keyboard and mouse . Software, on the other hand, refers to a set of instructions which enable the hardware to perform a specific set of tasks

Luden [163]

Answer:

Biomedical Science

The application of the principles of the natural sciences, especially biology and physiology to clinical medicine

Control group

The group in an experiment where the independent variable being tested is not applied so that it may serve as a standard for comparison against the experimental group where the independent variable is applied.

Dependent Variable

The measurable affect, outcome, or response in which the research is interested.

Experiment

A research study conducted to determine the effect that one variable has upon another variable

Forensic Science

The application of scientific knowledge to questions of civil and criminal law

Hypothesis

Clear prediction of anticipated results of an experiment

Independent Variable

The variable that is varied or manipulated by the researcher

Negative control

Control group where the conditions produce a negative outcome. Negative control groups help identify outside influences which may be present that were not accounted for when the procedure was created

Personal protective equipment

Specialized clothing or equipment, worn by an employee for protection against infectious materials.(as defined by OSHA)

Positive control

Group expected to have a positive result, allowing the researcher to show that the experiment set up was capable of producing results.

Adenine

A component of nucleic acids, energy carrying molecule such as ATP, and certain co enzymes. Chemically it is a purine base.

Chromosome

Any of the usually linear bodies in the nucleus that contain genetic material.

Cytosine

A component of nucleic acids that carries hereditary information in DNA and RNA in cells . Chemically it is a pyrimidine base.

Deoroxyribonucleic acid

A double-stranded helical nucleic acid molecule capable of replicating and determining the inherited structure of a cell proteins

Gel electrophoresis

The separation of nucleic acids or proteins, on the basis of their size and electrical charge, by measuring their movement through an electrical field in a gel.

Gene

A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA.( or RNA in some viruses).

Guanine

A component of nucleic acids that carries hereditary information in DNA and RNA in cells. Chemically it is a purine base.

Helix

Something in spiral form.

Model

A simplified version of something complex used, for example, to analyze and solve problems or make predictions.

Nucleotide

A building block of DNA, consisting of a 5 carbon sugar convalently bonded to a nitrogenous base and a phosphate group.

Restriction enzymes

A degradative enzyme that recognizes specific nucleotide sequences and cuts up DNA

Restriction fragment length polyphorisms (RFLPs)

Differences in DNA sequences on homologous chromosomes that can result in different patterns of restriction fragment lengths (DNA segments resulting from treatment with restriction enzymes)

Thymine

A component of nucleic acid that carries hereditary information in DNA cells. Chemically, it is a pyrimidine base

Autopsy

An examination of the body after death usually with such dissections as will expose the vital organs for determining the cause of death

Bibliography

a document showing all the sources used to research information

Citation

A written reference to a specific work by a particular author or creator which identifies the document in which the work may be found

Documentation

The act of creating citations to identify resources used in writing a work

Health Insurance Portability and Accountability Act (HIPAA)

A comprehensive set of standards and practices designed to give patients specific rights regarding their personal health information

Medical examiner

A physician who performs an autopsy when death may be accidental or violent. He/she may also serve in some jurisdictions as the coroner.

Explanation:

This is what I found when I searched up pltw chapter 1.2-1.3 answers.

I did this because there was not really a question in there.

The most common size for a brochure is _____.

Juli2301 [7.4K]

3.5X2 cannot be the answer as it too small and not enough information can be put into it. The common size for tri-fold brochures is 8.5X11 or letter size even when 8.5X14 is also a size used it is not the most common size.

Produce an infinite collection of sets A1,A2,A3, . . . with the property that every Ai has an infinite number of elements, Ai ∩

atroni [7]

Answer:

Produce an infinite collection of sets A1,A2,A3, . . . with the property that every Ai has an infinite number of elements, Ai ∩ Aj = ∅ for all i = j, and [infinity] i=1 Ai = N.

Explanation:

Solution

For n ∈ N,

define A_n = {2 ^n−1 ,(3)(2n−1 ),(5)(2^n−1 ),(7)(2^n−1 ), . . .}

I.e. A_n is all odd multiples of 2^n−1 . We must show that these sets satisfy the desired properties.

• (Infinite Number of Elements).

It is clear that the set A_n = {2 ^n−1 ,(3)(2^n−1 )(5)(2^n−1 ),(7)(2^n−1 ), . . .} has infinitely many elements.

• (Disjoint).

Given A_n and A_m with n ≠ m, we can assume, without loss of generality, that n < m. Suppose that there existed some x ∈ A_n ∩ A_m. Then by definition of these sets, there exists some odd numbers k and l such that x = 2^n−1 . k = 2^m−1 . l.

However since n < m, we have that n ≤ m − 1, and therefore we can write 2^m−1 = (2^n )(2 i ) with i ≥ 0. Hence we have 2^n−1 . k = 2^n. 2 ^i. l

Dividing both sides by 2^n−1 yields k = (2)(2^i ) .l, which contradicts the assumption that k is odd. Therefore A_n ∩ A_m = ∅.

• (Union is N).

We want to show that [infinity] i=1 A_n = N.

(⊆). Since each A_n is a subset of N, the union of these sets is a subset of N as well.

(⊇).Given any x ∈ N, we can write x = 2^n−1 . k for some n ∈ N where k is odd. Then x ∈ A_n, as desired.
