5- Note that questions 5 and 6 are -linked-- Question 5 is the first s.pdfJoeltfNashq
5. Note that questions 5 and 6 are "linked". Question 5 is the first step, crossing two "true
breeding parents (P) in order to create the F 1 offspring that are double heterozygotes. Question 6
is the second step, crossing two F 1 double heterozygotes to create the F 2 offspring. In Mendel's
experiments, the pod color gene and the seed shape gene were located on different chromosomes
(in other words, they were not linked. They assort independently). Green pods (G) are dominant
over yellow pods ( g ) and tall stems ( T ) are dominant over dwarf stems ( t ) . You are given
two true-breeding plants (homozygous at both genes). In the parental (P) generation, one parent
has green pods and dwarf stems and the second parent has yellow pods and tall stems. Your key:
G is the dominant allele, it stands for what trait? g is the recessive allele, it stands for what trait?
T is the dominant allele, it stands for what trait? t is the recessive allele, it stands for what trait?
Genotype of true breeding Parent 1: Genotype(s) of Parent 1's gametes (also write these above
the columns): Genotype of true breeding Parent 2: Genotype(s) of Parent 2 's gametes (also write
these to the left of the rows): Proportion and phenotype(s) of offspring: 6. Note that questions 5
and 6 are "linked". Question 5 is the first step, crossing two "true breeding" parents ( P ) in order
to create the F 1 offspring that are double heterozygotes. Question 6 is the second step, crossing
two F 1 double heterozygotes to create the F 2 offspring. As in question 5 , the pod color gene
and the seed shape gene were located on different chromosomes (in other words, they were not
linked. They assort independently). Green pods (G) are dominant over yellow pods ( g ) and tall
stems ( T ) are dominant over dwarf stems (f). If you cross an F 1 from question 5 (above) with
another F 1 from question 5 , this is a dihybrid cross. Remember that you are dealing with two
genes. Your key: G is the dominant allele, it stands for what trait? g is the recessive allele, it
stands for what trait? T is the dominant allele, it stands for what trait? t is the recessive allele, it
stands for what trait? Genotype of Parent 1 (who is also the F 1 offspring from question 5):

3.2E Recently, the European Union made funds available to set-up a crossnational research
database that stores information concerning scientific articles of researchers working at
institutions in the EU. Science Connect is the company that will be setting up this database. The
system will store information regarding scientific staff (persons) and research institutions. Both
are uniquely identified by a person ID and an institution code, respectively. The following is also
recorded for each person: a phone number, keywords that identify his/her key research topics and
the institution he/she works for. A person can be an author of one article and a reviewer of
another peer-reviewed article at the same time. The database will store the following information
concerning scientific articles. Each scientific article is uniquely identified by a DOI (a document
object identifier), and the system also stores the title and the authors of the article. In the case of
multiple authors, the position of each author is stored. Science Connect distinguishes between
two types of scientific articles: a scientific article is either a peer-reviewed paper or a technical
report. The system stores the citation count of peer-reviewed papers and who reviewed the paper.
A technical report is always published by a single research institution, while research institutions
can of course publish multiple technical reports. The system keeps track of the different
scientific publishers (e.g., IEEE, Elsevier). A publisher is identified by name. A publisher can
publish multiple journals to which research institutions can subscribe. These journals are given a
name by the publisher (e.g., Decision Support Systems). Publishers can have journals with the
same name as other publishers; e.g., it is possible that both IEEE and Elsevier have a journal
with the title Management Science. The impact factor, which measures the scientific impact of a
journal, is also stored. Finally, only peer-reviewed papers are published in journals, not technical
reports. Make an EER model and UML class diagram to model the data requirements. Comment
on the limitations of both models..

streaming website called Musicmatic. Being economists, they are unaware of the specificities of
databases and have therefore asked you to create an EER model. A large number of songs will be
made available through their website, and the following information on each song needs to be
stored: title, year, length, and genre. Also, artist information will be added, including date of
birth, name and a URL to a website (e.g., Wikipedia page) with additional information on the
artist. You can assume an artist is uniquely identified by his/her name, and that a song always
belongs to exactly one artist. The Musicmatic students also point out that songs having the same
title are possible, and only the combination of song and artist can be assumed to be unique. The
database will also have to store information on the people using Musicmatic. It was decided to
only discriminate between two types of users: the regular users who will be able to buy music,
and the business users who will deliver the content (upload the music). The following
information is recorded on each user: (unique) ID, name, and address. Business users will also
have a VAT number. The students want to offer a flexible service, and decided business users
can only upload individual songs. These songs are classified either as singles or hits, and regular
users can directly buy the singles. Otherwise, people can compose an album consisting of
multiple hits (no singles). The position of each hit in the album is stored as a track number in the
database. Note that the album of regular users can be turned into a suggestion to other regular
users with similar purchasing behavior. Finally, a user can be a regular user on some occasions
(e.g., when downloading a single or album), and a business user at other times (e.g., when
uploading self-made songs to Musicmatic). Make an EER model and UML class diagram to
model the data requirements. Comment on the limitations of both models..

only discriminate between two types of users: the regular users who will be able to buy music,
and the business users who will deliver the content (upload the music). The following
information is recorded on each user: (unique) ID, name, and address. Business users will also
have a VAT number. The students want to offer a flexible service, and decided business users
can only upload individual songs. These songs are classified either as singles or hits, and regular
users can directly buy the singles. Otherwise, people can compose an album consisting of
multiple hits (no singles). The position of each hit in the album is stored as a track number in the
database. Note that the album of regular users can be turned into a suggestion to other regular
users with similar purchasing behavior. Finally, a user can be a regular user on some occasions
(e.g., when downloading a single or album), and a business user at other times (e.g., when
uploading self-made songs to Musicmatic). Make an EER model and UML class diagram to
model the data requirements. Comment on the limitations of both models..

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
