Egypt had 31 dynasties over its history that were grouped into three major kingdoms - the Old, Middle, and New Kingdoms. The Old Kingdom from 2700-2200 BCE was referred to as the "Pyramid Age" and saw King Menes unite Upper and Lower Egypt. Pharaohs had absolute power as religious and political leaders during this time. The Middle Kingdom from 2100-1800 BCE was a calmer period where pharaohs did not have complete control and invested in infrastructure projects. The powerful New Kingdom from 1570-1080 BCE expanded Egypt's empire before internal conflicts weakened it and led to foreign invasions.
Ibn Battuta was a 14th century Moroccan explorer who traveled extensively throughout Africa, Asia, and Europe over a period of 30 years, covering around 75,000 miles. Like Marco Polo, he documented his travels in a book called Rihla, describing places he visited like Baghdad, Damascus, and the Egyptian pyramids. Though less famous initially than Marco Polo, Ibn Battuta is gaining recognition as more become aware of his journeys and written accounts.
The document discusses writing in ancient Egypt, including hieroglyphics, papyrus, and scribes. It describes where writing was used, such as in scribe schools, fields, tombs, the army, government, and temples. Scribes were trained to read and write hieroglyphics and held important roles keeping records and communicating messages. Writing played a significant part in tomb decoration to help with the afterlife and was important for record keeping in government and rituals in temples.

Oppgave i IKT MOOC høsten 2014.
Elever kan sjekke om de vet forskjellen på ulike funksjonstypene og hva som kjennetegner alkaner, alkener, alkyner, alkoholer og karboksylsyrer.

4 celledeling og krysninger, Kap 1 i Tellus 10, Aschehoug
1. Celledeling og krysninger s. 24-30 Tellus 10
Gregor Mendel: 1822-1884
Veronica Bergan
Genetikkens far
2. Læreplanmål du skal kunne i denne økta:
• Tegne og beskrive celledeling:
• Vanlig celledeling
• Reduksjondeling (dannelse av kjønnsceller)
• Forklare forskjellen på dominante og recessive (vikende) gener
• Homozygot
• Heterozygot
• Beskrive hvordan egenskaper arves ved hjelp av krysningsskjema
Veronica Bergan
3. Kromosompar – samme gen i to utgaver
• Gen = del av kromosomet som
gir en egenskap (et protein)
• To kromosomer gir to kopier
eller alleler av samme gen

4. A = dominant gen a = recessivt (vikende) gen
Homozygot (AA)
rød
Homozygot (aa)
hvit
Heterozygot (Aa)
rød
5. Mendels erteplanter
• Oppdagelse ved kryssing av to
gule erteplanter
• Enten bare gule
• ¾ gule og ¼ grønne planter
6. Homozygot (AA) x Heterozygot (Aa) Heterozygot (Aa) x Heterozygot (Aa)
Recessive gener kommer bare til uttrykk når cellen er homozygot (aa) for det vikende genet
11. Oppgaver s.24-30 i Tellus 10
1. Forklar begrepene: allele gener, recessiv,
dominant, homozygot og heterozygot
2. Beskriv forskjeller og likheter ved vanlig
celledeling og reduksjonsdeling
3. Hva er et kryssningsskjema og hva forteller
det oss?
4. Rita har blå øyne (blå øyne er recessivt).
Begge foreldrene har brune øyne (brun er
dominant). Forklar hvordan det er mulig!
