Which of the following is best known as a business network LinkedIn, Facebook, Twitter or Word Press?

Write the function greeting that takes a string as input. That string will be formatted as Name Age Hobby, without any punctuati

Dmitriy789 [7]

Answer:

The function in Python is as follows:

def greetings(details):

details = details.split(' ')

print('Hello, '+details[0]+'!, I also enjoy '+details[2])

Explanation:

This defines the function

def greetings(details):

This splits the input string by space

details = details.split(' ')

This prints the required output

print('Hello, '+details[0]+'!, I also enjoy '+details[2])

After splitting, the string at index 0 represents the name while the string at index 2 represents the hobby

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.

PS:

I'm sorry if this is too long for you to read.

Give me brainliest, if you want to, that is.

This program is to compute and write to a file the GPA for student scores read from an input file. The point values of the grade

VARVARA [1.3K]

Answer:

#Take input from the user

filename=input('Enter name of input file: ')

total_units=0#Total number of units for a student

total_score=0#Total score of a student

#Assign a score to each grade. I have reduced 0.33 for each grade. Change here if you need to

grade={'A':4.0,'A-':3.67,'B+':3.34,'B':3.01,'B-':2.68,'C+':2.35,'C':2.02,'C-':1.69,'D+':1.36,'D':1.03}

try:

with open(filename,"r") as input_file:#Open the file for input(reading)

output_file=open("GPA_output.txt","w") #Create and open GPA_output.txt if it doesn't exist for writing

for student_record in input_file:#read from input file

if("," in student_record):#if there is a , that means this is the student name

student_name=student_record.strip('\n')#Remove \n from student name

continue

else:

if(" " in student_record):#If a line contains spaces then its the student's grades for a course

student=student_record.split(" ")#Split to find the coursename, units and grade

#student[0]=coursename student[1]=units student[2]=grade

total_units+=int(student[1])#Calculate total units for 1 student

total_score+=int(student[1])*grade[student[2].strip('\n')]#Find the total score of a student

#grade[student[2]] will lookup for the score that we initialized earlier

#if student has a grade as A then this will look up as grade['A'] which will return 4

#Find the total score as product of this grade and units for this course

continue

else:

if(total_units>0):#Check if score has been calculated for a student earlier

print("in")

GPA=total_score/total_units#Calculate the GPA

output_file.write("%-26s%.2f\n" % (student_name, GPA))#Write the GPA and Student Name in the required format

total_units=0#reset the units

total_score=0#reset the score

if(total_units>0):#Essential for the case when the file doesn't end with a new line(Check if total_units is not 0) which means a record is pending

#to be written to the file

GPA=total_score/total_units#Calculate the GPA

output_file.write("%-26s%.2f\n" % (student_name, GPA))#Write the GPA and Student Name in the required format

total_units=0#reset the units

total_score=0#reset the score

input_file.close()#Close the input file

output_file.close()#Close the output file

except IOError as e:

print("Problem in Opening the required file")#Print a message if file cannot be opened

Explanation:

The program has been tested for all 3 scenarios mentioned i.e.

a. If the file ends without \n

b. If the file ends with 2 \n

c. If the file ends with 1 \n

PS: The Program will run irrespective of how it ends. Even if there are many \n at the end of file, the program will be fine.
